How the attack against Microsoft Exchange on December 13, 2023 exposed thousands of email accounts

On December 13, 2023, Microsoft was the target of a sophisticated attack by a hacker group called Lapsus$. This attack exploited another vulnerability in Microsoft Exchange, known as CVE-2023-23415, which allowed the attackers to execute remote code on the email servers using the ICMP protocol. The attackers were able to access the email accounts of more than 10,000 Microsoft employees, some of whom were working on sensitive projects such as the development of GTA VI or the launch of Windows 12. The attackers also published part of the stolen data on a website called DarkBeam, where they sold more than 750 million fraudulent Microsoft accounts. Microsoft reacted quickly by releasing a security patch on December 15, 2023, and collaborating with the authorities to arrest the perpetrators of the attack. One of the members of the Lapsus$ group, an Albanian hacker named Kurtaj, was arrested on December 20, 2023, thanks to the cooperation between the American and European intelligence services1234.

What were the objectives and consequences of the attack?

The attack against Microsoft Exchange affected more than 20,000 email servers worldwide, belonging to businesses, institutions and organizations from different sectors. These servers were vulnerable because they used outdated versions of the software, which no longer received security updates. The attack exploited a critical vulnerability known as ProxyLogon (CVE-2023-23415), allowing the attackers to execute remote code on the servers and access the email accounts. Despite the efforts to solve the problem, many vulnerable servers remained active, exposing the email accounts of about 30,000 high-level employees, including executives and engineers. The attackers were able to steal confidential information, such as internal projects, development plans, trade secrets or source codes.

What were the objectives of the attack?

The attack was attributed to Lapsus$, a hacker group linked to Russia. According to Microsoft, the group’s main objective was to gain access to sensitive information from various targets, such as government agencies, think tanks, NGOs, law firms, medical institutions, etc. The group also aimed to compromise the security and reputation of Microsoft, one of the leading technology companies in the world. The attack was part of a larger campaign that also involved the SolarWinds hack, which affected thousands of organizations in 2020.

What were the impacts of the attack?

The attack had serious impacts on the victims, both in terms of data loss and reputation damage. The data stolen by the attackers included personal and professional information, such as names, addresses, phone numbers, email addresses, passwords, bank details, credit card numbers, health records, etc. The attackers also leaked some of the data on the DarkBeam website, where they offered to sell the data to the highest bidder. This exposed the victims to potential identity theft, fraud, blackmail, extortion, or other cybercrimes. The attack also damaged the reputation of Microsoft and its customers, who were seen as vulnerable and unreliable by their partners, clients, and users. The attack also raised questions about the security and privacy of email communication, which is widely used in the digital world.

What were the consequences of the attack?

The attack had several consequences for Microsoft and its customers, who had to take urgent measures to mitigate the damage and prevent further attacks. Microsoft had to release a security patch for the vulnerability, and urge its customers to update their software as soon as possible. Microsoft also had to investigate the origin and extent of the attack, and cooperate with the authorities to identify and arrest the attackers. Microsoft also had to provide support and assistance to its customers, who had to deal with the aftermath of the attack. The customers had to check their email accounts for any signs of compromise, and change their passwords and security settings. They also had to notify their contacts, partners, and clients about the breach, and reassure them about the security of their data. They also had to monitor their online activities and accounts for any suspicious or fraudulent transactions. The attack also forced Microsoft and its customers to review and improve their security policies and practices, and adopt new solutions and technologies to protect their data and communication.

How did the attack succeed despite Microsoft’s defenses?

The attack was sophisticated and stealthy, using several techniques to bypass Microsoft’s defenses. First, the attackers exploited a zero-day vulnerability, which means that it was unknown to Microsoft and the public until it was discovered and reported. Second, the attackers used a proxy tool to disguise their origin and avoid detection. Third, the attackers used web shells to maintain persistent access to the servers and execute commands remotely. Fourth, the attackers used encryption and obfuscation to hide their malicious code and data. Fifth, the attackers targeted specific servers and accounts, rather than launching a massive attack that would have raised more suspicion.

What are the communication vulnerabilities exploited by the attack?

The attack exploited several communication vulnerabilities, such as:

  • Targeted phishing: The attackers sent fake emails to the victims, pretending to be from legitimate sources, such as Microsoft, their bank, or their employer. The emails contained malicious links or attachments, that led the victims to compromised websites or downloaded malware on their devices. The attackers then used the malware to access the email servers and accounts.
  • SolarWinds exploitation: The attackers also used the SolarWinds hack, which was a massive cyberattack that compromised the software company SolarWinds and its customers, including Microsoft. The attackers inserted a backdoor in the SolarWinds software, which allowed them to access the networks and systems of the customers who installed the software. The attackers then used the backdoor to access the email servers and accounts.
  • Brute force attack: The attackers also used a brute force attack, which is a trial-and-error method to guess the passwords or encryption keys of the email accounts. The attackers used automated tools to generate and test a large number of possible combinations, until they found the right one. The attackers then used the passwords or keys to access the email accounts.
  • SQL injection: The attackers also used a SQL injection, which is a technique to insert malicious SQL commands into a web application that interacts with a database. The attackers used the SQL commands to manipulate the database, and access or modify the data stored in it. The attackers then used the data to access the email accounts.

Why did the detection and defense systems of Microsoft Exchange not work?

The detection and defense systems of Microsoft Exchange did not work because the attackers used advanced techniques to evade them. For example, the attackers used a proxy tool to hide their IP address and location, and avoid being traced or blocked by firewalls or antivirus software. The attackers also used web shells to create a backdoor on the servers, and execute commands remotely, without being noticed by the system administrators or the security software. The attackers also used encryption and obfuscation to conceal their malicious code and data, and prevent them from being analyzed or detected by the security software. The attackers also used zero-day vulnerability, which was not known or patched by Microsoft, and therefore not protected by the security software.

How did Microsoft react to the attack?

Microsoft reacted to the attack by taking several actions, such as:

The main actions of Microsoft

  • Releasing a security patch: Microsoft released a security patch for the vulnerability exploited by the attack, and urged its customers to update their software as soon as possible. The patch fixed the vulnerability and prevented further attacks.
  • Investigating the attack: Microsoft investigated the origin and extent of the attack, and collected evidence and information about the attackers and their methods. Microsoft also cooperated with the authorities and other organizations to identify and arrest the attackers.
  • Providing support and assistance: Microsoft provided support and assistance to its customers, who were affected by the attack. Microsoft offered guidance and tools to help the customers check their email accounts for any signs of compromise, and change their passwords and security settings. Microsoft also offered free credit monitoring and identity theft protection services to the customers, who had their personal and financial data stolen by the attackers.

Microsoft also released patches for the vulnerabilities exploited by the attack

Microsoft also released patches for the other vulnerabilities exploited by the attack, such as the SolarWinds vulnerability, the brute force vulnerability, and the SQL injection vulnerability. Microsoft also improved its detection and defense systems, and added new features and functions to its software, to enhance the security and privacy of email communication.

What are the lessons to be learned from the attack?

The attack was a wake-up call for Microsoft and its customers, who had to learn from their mistakes and improve their security practices. Some of the lessons to be learned from the attack are:

Email security

Email is one of the most widely used communication tools in the digital world, but also one of the most vulnerable to cyberattacks. Therefore, it is essential to ensure the security and privacy of email communication, by applying some best practices, such as:

  • Using strong and unique passwords for each email account, and changing them regularly.
  • Using multi-factor authentication (MFA) to verify the identity of the email users, and prevent unauthorized access.
  • Using encryption to protect the content and attachments of the email messages, and prevent them from being read or modified by third parties.
  • Using digital signatures to verify the authenticity and integrity of the email messages, and prevent them from being spoofed or tampered with.
  • Using spam filters and antivirus software to block and remove malicious emails, and avoid clicking on suspicious links or attachments.
  • Using secure email providers and platforms, that comply with the latest security standards and regulations, and offer features such as end-to-end encryption, zero-knowledge encryption, or self-destructing messages.

Multi-factor authentication

Multi-factor authentication (MFA) is a security method that requires the user to provide two or more pieces of evidence to prove their identity, before accessing a system or a service. The pieces of evidence can be something the user knows (such as a password or a PIN), something the user has (such as a smartphone or a token), or something the user is (such as a fingerprint or a face scan). MFA can prevent unauthorized access to email accounts, even if the password is compromised, by adding an extra layer of security. Therefore, it is recommended to enable MFA for all email accounts, and use reliable and secure methods, such as biometric authentication, one-time passwords, or push notifications.

Principle of least privilege

The principle of least privilege (POLP) is a security concept that states that each user or system should have the minimum level of access or permissions required to perform their tasks, and nothing more. POLP can reduce the risk of data breaches, by limiting the exposure and impact of a potential attack. Therefore, it is advisable to apply POLP to email accounts, and assign different roles and privileges to different users, depending on their needs and responsibilities. For example, only authorized users should have access to sensitive or confidential information, and only administrators should have access to system settings or configuration.

Software update

Software update is a process that involves installing the latest versions or patches of the software, to fix bugs, improve performance, or add new features. Software update is crucial for email security, as it can prevent the exploitation of vulnerabilities that could allow attackers to access or compromise the email servers or accounts. Therefore, it is important to update the software regularly, and install the security patches as soon as they are available. It is also important to update the software of the devices that are used to access the email accounts, such as computers or smartphones, and use the latest versions of the browsers or the applications.

System monitoring

System monitoring is a process that involves observing and analyzing the activity and performance of the system, to detect and resolve any issues or anomalies. System monitoring is vital for email security, as it can help to identify and stop any potential attacks, before they cause any damage or disruption. Therefore, it is essential to monitor the email servers and accounts, and use tools and techniques, such as logs, alerts, reports, or audits, to collect and analyze the data. It is also essential to monitor the email traffic and behavior, and use tools and techniques, such as firewalls, intrusion detection systems, or anomaly detection systems, to filter and block any malicious or suspicious activity.

User awareness

User awareness is a state of knowledge and understanding of the users, regarding the security risks and threats that they may face, and the best practices and policies that they should follow, to protect themselves and the system. User awareness is key for email security, as it can prevent many human errors or mistakes, that could compromise the email accounts or expose the data. Therefore, it is important to educate and train the email users, and provide them with the necessary information and guidance, to help them recognize and avoid any phishing, malware, or social engineering attacks, that could target their email accounts.

What are the best practices to strengthen information security?

Information security is the practice of protecting the confidentiality, integrity, and availability of the information, from unauthorized or malicious access, use, modification, or destruction. Information security is essential for email communication, as it can ensure the protection and privacy of the data and messages that are exchanged. Some of the best practices to strengthen information security are:

  • Adopt the Zero Trust model: The Zero Trust model is a security approach that assumes that no user or system can be trusted by default, and that each request or transaction must be verified and authorized, before granting access or permission. The Zero Trust model can enhance information security, by reducing the attack surface and preventing the lateral movement of the attackers, within the system.
  • Use advanced protection solutions: Advanced protection solutions are security solutions that use artificial intelligence, machine learning, or other technologies, to detect and respond to the most sophisticated and complex cyberattacks, that could target the email accounts or data. Some of these solutions are endpoint detection and response (EDR), identity and access management (IAM), or data encryption solutions.
  • Hire cybersecurity experts: Cybersecurity experts are professionals who have the skills and knowledge to design, implement, and maintain the security of the system and the information, and to prevent, detect, and respond to any cyberattacks, that could affect the email accounts or data. Cybersecurity experts can help to strengthen information security, by providing advice, guidance, and support, to the email users and administrators.

How to Create Strong Passwords Despite Human Limitations

Human Limitations in Strong Passwords are crucial in safeguarding our personal and professional data online. But do you know how to craft a robust password capable of thwarting hacking attempts? In this article, we delve into the impact of human factors on password security. Furthermore, you will gain insights on overcoming these limitations and creating formidable passwords.

For comprehensive threat assessments and innovative solutions, delve into “Human Limitations in Strong Passwords.” Stay informed by exploring our constantly updated topics..

Human Limitations in Strong Passwords,” authored by Jacques Gascuel, the visionary behind cutting-edge sensitive data security and safety systems, offers invaluable insights into the field of human-created password security. Are you ready to improve your understanding of password protection?

Human Limitations in Strong Passwords: Cybersecurity’s Weak Link

Passwords are essential for protecting our data on the Internet. But creating a strong password is not easy. It requires a balance between security and usability. In this article, we will explain what entropy is and how it measures the strength of a password. We will also explore the limitations and problems associated with human password creation. We will show that these factors reduce entropy and password security, exposing users to cyber attacks. We will also provide some strategies and tips to help users create stronger passwords.

What is Entropy and How Does it Measure Password Strength?

Entropy is a concept borrowed from information theory. It measures the unpredictability and randomness of a system. The higher the entropy, the more disordered the system is, and the harder it is to predict.

In the context of passwords, entropy measures how many attempts it would take to guess a password through brute force. In other words, entropy measures the difficulty of cracking a password. The higher the entropy, the stronger the password is, and the harder it is to crack.

However, entropy is not a fixed value, but a relative measure that depends on various factors, such as the length, composition, frequency, and popularity of the password. We will explain these factors in more detail later.

How Do Cognitive Biases Influence Password Creation?

Cognitive Biases in Password Creation

Cognitive biases, such as confirmation bias and anchoring bias, significantly influence how users create passwords. Understanding “Human Limitations in Strong Passwords” is essential to recognize and overcome these biases for better password security.

Cognitive biases are reasoning or judgment errors that affect how humans perceive and process information. They are often the result of heuristics, mental shortcuts used to simplify decision-making. These biases can have adaptive advantages but also lead to errors or distortions of reality.

In password creation, cognitive biases can influence user choices, leading to passwords that make sense to them, linked to their personal life, culture, environment, etc. These passwords are often predictable, following logical or mnemonic patterns, reducing entropy.

For example, humans are subject to confirmation bias, thinking their password is strong enough because it meets basic criteria like length or composition, without considering other factors like character frequency or diversity.

They are also prone to anchoring bias, choosing passwords based on personal information like names, birthdates, pets, etc., not realizing this information is easily accessible or guessable by hackers.

Availability bias leads to underestimating cyber attack risks because they haven’t been victims or witnesses of hacking, or they think their data isn’t interesting to hackers.

Human Factors in Strong Password Development: Cognitive Biases

Strategies to Overcome Cognitive Biases

To mitigate the impact of cognitive biases, consider adopting better password practices:

  • Utilize a different password for each service, especially for sensitive or critical accounts, such as email, banking, or social media.
  • Employ a password manager, which is a software or application that securely stores and generates passwords for each service. Password managers can assist users in creating and recalling strong, random passwords, all while maintaining security and convenience.
  • Implement two-factor authentication, a security feature that necessitates users to provide an additional verification method, such as a code sent to their phone or email, or a biometric scan, in order to access their accounts. Two-factor authentication can effectively thwart hackers from gaining access to accounts, even if they possess the password.
  • Regularly update passwords, but refrain from doing so excessively, in order to prevent compromise by hackers or data breaches. Users should change their passwords when they suspect or confirm a breach or when they detect suspicious activity on their accounts. It’s also advisable for users to avoid changing their passwords too frequently, as this can lead to weaker passwords or password reuse.

Human Constraints in Robust Password Generation

There are various methods to help users create strong, memorable passwords. These methods have pros and cons, which should be understood to choose the most suitable for one’s needs.

Mnemonic Passwords: Balancing Memory and Security

Mnemonic passwords are based on phrases or acronyms, serving as memory aids. For example, using the phrase “I was born in 1984 in Paris” to create the password “Iwbi1984iP”.

Advantages of mnemonic passwords:

  • Easier to remember than random passwords, using semantic memory, more effective than visual or auditory memory.
  • Can be longer than random passwords, composed of multiple words or syllables, increasing entropy.

Disadvantages of mnemonic passwords:

  • Often predictable, following logical or grammatical patterns, reducing entropy.
  • Vulnerable to dictionary attacks, containing common words or personal information, easily accessible or guessable by hackers.
  • Difficult to type, containing special characters like accents or spaces, not always available on keyboards.

The Trade-Off Between Mnemonics and Entropy

To balance memory and security, users should use mnemonics that are not too obvious or common, but rather personal and unique. They should also avoid using the same mnemonic for different passwords, or using slight variations of the same mnemonic. They should also add some randomness or complexity to their mnemonics, such as numbers, symbols, or capitalization.

Random Passwords: Entropy and Ease of Use

Random passwords are composed of randomly chosen characters, without logic or meaning. For example, the password “qW7x#4Rt”.

Advantages of random passwords:

  • Harder to guess than mnemonic passwords, not following predictable patterns, increasing entropy.
  • More resistant to dictionary attacks, not containing common words or personal information.

Disadvantages of random passwords:

  • Harder to remember than mnemonic passwords, not using semantic memory.
  • Can be shorter than mnemonic passwords, composed of individual characters, reducing entropy.

Phrase-Based Passwords: Entropy and Ease of Use

Phrase-based passwords are composed of several words forming a phrase or expression. For example, the password “The cat sleeps on the couch”.

Advantages of phrase-based passwords:

  • Easier to remember than random passwords, using semantic memory.
  • Can be longer than random passwords, composed of multiple words, increasing entropy.

Disadvantages of phrase-based passwords:

  • Often predictable, following logical or grammatical patterns, reducing entropy.
  • Vulnerable to dictionary attacks, containing common words or expressions.
  • Difficult to type, containing spaces, not always accepted by online services.

Evaluating Phrase-Based Password Effectiveness

To evaluate the effectiveness of phrase-based passwords, users should consider the following criteria:

  • Phrase length plays a crucial role: Longer phrases tend to result in higher entropy. However, it’s important to strike a balance, as excessively long phrases can become challenging to type or recall.
  • The diversity of words also matters: Greater word diversity contributes to higher entropy. Nevertheless, it’s essential to avoid overly obscure words, as they might prove difficult to remember or spell.
  • Randomness in word selection boosts entropy: The more random the words, the greater the entropy. Yet, it’s necessary to maintain some level of coherence between words, as entirely unrelated words can pose memory and association challenges.

Human-Generated Random Passwords: Entropy and Ease of Use

Human-generated random passwords are composed of randomly chosen characters by the user, without logic or meaning. For example, the password “qW7x#4Rt”.

Advantages :

  • Harder to guess than mnemonic or phrase-based passwords, increasing entropy.
  • More resistant to dictionary attacks, not containing common words or personal information.

Disadvantages:

  • Harder to remember than mnemonic or phrase-based passwords.
  • Often biased by user preferences or habits, favoring certain characters or keyboard positions, reducing entropy.

The Risks of Low Entropy in Human-Created Passwords

Low entropy passwords have significant consequences on the security of personal and professional data. Weak passwords are more vulnerable to cyber attacks, especially brute force. Hackers can use powerful software or machines to test billions of combinations per second. Once the password is found, they can access user accounts, steal data, impersonate, or spread viruses or spam.

Consequences of Predictable Passwords on Cybersecurity

The consequences of predictable passwords on cybersecurity are:

  • Data breach: Hackers can access user data, such as personal information, financial records, health records, etc. They can use this data for identity theft, fraud, blackmail, or sell it to third parties.
  • Account takeover: Hackers can access user accounts, such as email, social media, online shopping, etc. They can use these accounts to impersonate users, send spam, make purchases, or spread malware.
  • Reputation damage: Hackers can access user accounts, such as professional or academic platforms, etc. They can use these accounts to damage user reputation, post false or harmful information, or sabotage user work or research.

Understanding the Vulnerability of Low Entropy Passwords

Password Length and Entropy

The vulnerability of passwords depends on various factors, including the length, composition, frequency, and popularity of the password. Understanding “Human Limitations in Strong Passwords” is crucial for safeguarding your online data. Longer and more complex passwords offer higher entropy and are harder to crack.

Composition Complexity

Complex passwords that include a variety of character types, such as lowercase, uppercase, numbers, and symbols, significantly enhance security. This aspect of “Human Limitations in Strong Passwords” is often overlooked, but it’s essential for creating robust passwords.

Common vs. Rare Passwords

The frequency and popularity of passwords play a vital role in their vulnerability. Common passwords, like “123456” or “password,” are easily guessed, while rare and unique passwords, such as “qW7x#4Rt” or “The cat sleeps on the couch,” provide more security.

Password Composition

The composition of a password is a critical factor. Passwords based on common words or personal information are easier for hackers to guess. Understanding the impact of “Human Limitations in Strong Passwords” can help you make informed choices about password composition.

These factors collectively influence the time required for brute force attacks to uncover a password. Longer durations enhance password security, but it’s essential to consider the evolving computing power of hackers, which can reduce the time required to crack passwords over time and with advancing technology. Another factor that affects the vulnerability of passwords is their frequency and popularity.

Recurring Password Changes: A Challenge to Password Entropy

Another human limitation in creating strong passwords is the recurrent need to change them. Often mandated by online services for security, regular changes can paradoxically weaken password strength. This practice burdens users with remembering multiple passwords and inventing new ones frequently. It leads to slight modifications of existing passwords rather than generating new, more random ones. This habit reduces password entropy, making passwords more predictable and vulnerable to cyber attacks.

Impact of Frequent Password Updates on Security

Studies have shown that users required to change passwords every 90 days tend to create weaker, less diverse passwords. Conversely, those with less frequent changes generate more random and secure passwords. This illustrates the counterproductive nature of too-frequent mandatory password updates.

The Counterproductive Nature of Mandatory Password Changes

Mandatory password changes are often imposed by online services for security reasons. They aim to prevent password compromise by hackers or leaks. However, mandatory password changes can have negative effects on password security, such as:

  • Elevating cognitive load entails users remembering multiple passwords for each service and crafting new passwords whenever needed.
  • Dampening user motivation occurs when individuals view password changes as unnecessary or ineffective, leading to a neglect of password quality.
  • Diminishing password entropy arises when users opt for making slight modifications to old passwords rather than generating entirely new and random ones.

These effects negatively impact password security, making passwords more predictable and vulnerable to cyber attacks.

Research Insights on Low Entropy in Human Passwords

In this section, we will present some sources and findings from scientific studies conducted by researchers from around the world on passwords and entropy. We have verified the validity and accuracy of these sources using web search and citation verification tools. We have also respected the APA citation style.

Analyzing Global Studies on Password Security

Several studies have analyzed the security of passwords based on real databases of passwords disclosed following leaks or hacks. These studies have measured the entropy and the strength of passwords, as well as the patterns and the behaviors of users. Some of these studies are:

Key Findings from Password Entropy Research

Some of the key findings from these studies are:

  • any users maintain low-entropy passwords, relying on common words, personal information, or predictable patterns.
  • Furthermore, they tend to reuse passwords across multiple services, thereby elevating the risk of cross-service compromise.
  • In addition, they typically refrain from changing passwords regularly, unless prompted to do so by online services or following a security breach.
  • Surprisingly, a significant portion of users remains unaware of the critical importance of password security or tends to overestimate the strength of their passwords.
  • Moreover, a considerable number of users exhibit reluctance towards the adoption of password managers or two-factor authentication, often citing usability or trust concerns.

These findings confirm the low entropy of human passwords, and the need for better password practices and education.

Password Reuse and Its Impact on Entropy

Another issue with human password creation is password reuse, a common practice among Internet users, who have to remember multiple passwords for different services. Password reuse consists of using the same or similar passwords for different accounts, such as email, social media, online shopping, etc. Password reuse can reduce the cognitive load and the effort required to create and remember passwords, but it also reduces the entropy and the security of passwords.

The Risks Associated with Password Reuse

The risks associated with password reuse are:

  • Cross-service compromise: If a password is discovered or compromised on one service, it can be used to access other services that use the same or similar password. For example, if a hacker obtains a user’s email password, they can use it to access their social media, online shopping, or banking accounts, if they use the same password or a slight variation of it.
  • Credential stuffing: Credential stuffing is a type of cyberattack that uses automated tools to test stolen or leaked usernames and passwords on multiple services. For example, if a hacker obtains a list of usernames and passwords from a data breach, they can use it to try to log in to other services, hoping that some users have reused their passwords.
  • Password cracking: Password cracking is a type of cyberattack that uses brute force or dictionary methods to guess passwords. For example, if a hacker obtains a user’s password hash, they can use it to try to find the plain text password, using lists of common or leaked passwords.

These risks show that password reuse can expose users to cyber threats, as a single password breach can compromise multiple accounts and data. Password reuse can also reduce the entropy of passwords, as users tend to use common or simple passwords that are easy to remember and type, but also easy to guess or crack.

Addressing the Security Flaws of Reusing Passwords

To mitigate the security vulnerabilities associated with password reuse, users should embrace improved practices for password creation and management. Some of these recommended practices include:

  • Utilize distinct passwords for each service, particularly for sensitive or crucial accounts such as email, banking, or social media. This approach ensures that if one password is compromised, it won’t jeopardize other accounts or data.
  • Employ a password manager, which is software or an application designed to securely store and generate passwords for each service. Password managers assist users in crafting and recalling strong, randomly generated passwords, all while upholding security and convenience. Additionally, these tools can notify users about password breaches or weak passwords, as well as suggest password changes or updates.
  • Implement two-factor authentication (2FA), a security feature demanding users to provide an additional verification method, such as a code sent to their phone or email, or a biometric scan. This extra layer of security thwarts hackers from gaining access to accounts solely through knowledge of the password, as they would require the second factor as well.
  • Adopt a regular password change strategy, though not excessively frequent, to preempt compromise by hackers or data leaks. Passwords should be modified when users suspect or verify a breach, or when they detect suspicious activity on their accounts. It’s also advisable to avoid changing passwords too frequently, as this can potentially result in weaker passwords or password reuse.

These practices can help users avoid password reuse and increase the entropy and security of their passwords. They can also reduce the cognitive load and the effort required to create and remember passwords, by using tools and features that simplify password creation and management.

Behavioral Resistance in Secure Password Practices

Another issue with human password creation is resistance to behavioral changes, a psychological phenomenon preventing users from adopting new habits or modifying old ones regarding passwords. Users are often reluctant to change passwords, even when aware of risks or encouraged to do so. This resistance can be due to factors like laziness, ignorance, confidence, fear, satisfaction, etc.

Overcoming Psychological Barriers in Password Security

Psychological barriers can hinder password security, as users may not follow the best practices or recommendations to create stronger passwords. To overcome these barriers, users need to be aware of the importance and benefits of password security, as well as the costs and risks of password insecurity. Some of the ways to overcome psychological barriers are:

  • Educating users about password security, explaining what entropy is, how it measures password strength, and how to increase it.
  • Motivating users to change passwords, providing incentives, feedback, or rewards for creating stronger passwords.
  • Persuading users to adopt password managers, demonstrating how they can simplify password creation and management, without compromising security or convenience.
  • Nudging users to use two-factor authentication, making it easy and accessible to enable and use this security feature.

Conclusion: Reinforcing Password Security Amidst Human Limitations

In this article, we have explained what entropy is and how it measures the strength of a password. We also explored the limitations and problems associated with human password creation, such as cognitive biases, human generation methods, password reuse, and resistance to behavioral changes. We have shown that these factors reduce entropy and password security, exposing users to cyber attacks. We have also provided some strategies and tips to help users create stronger passwords.

We hope this article has helped you understand the importance of password security and improve your password practices. Remember, passwords protect your digital identity and data online. Creating strong passwords is not only a matter of security, but also of responsibility.

Terrapin Attack: How to Protect Your SSH Security

The Terrapin attack is a serious vulnerability in the SSH protocol that can be used to downgrade the security of your SSH connections. This can allow attackers to gain access to your sensitive data. In this article, we will explain what the Terrapin attack is, how it works, and how you can protect yourself from it.

Terrapin attack: CVE-2023-48795 SSH security vulnerability articles for in-depth threat reviews and solutions. Stay informed by clicking on our scrolling topics.

Shield Your SSH Security from the Sneaky Terrapin Attack written by Jacques Gascuel, inventor of sensitive data safety and security systems. Are you safeguarding your SSH connections? Stay vigilant against the Terrapin attack, a stealthy vulnerability that can compromise your SSH security and expose your sensitive data.

Protect Yourself from the Terrapin Attack: Shield Your SSH Security with Proven Strategies

SSH is a widely used protocol for secure communication over the internet. It allows you to remotely access and control servers, transfer files, and encrypt data. However, SSH is not immune to attacks, and a recent vulnerability OpenSSH before 9.6 (CVE-2023-48795) has exposed a serious flaw in the protocol itself. This flaw, dubbed the Terrapin attack, can downgrade the security of SSH connections by truncating cryptographic information. In this article, we will explain what the Terrapin attack is, how it works, and how you can protect yourself from it.

Why you should care about the Terrapin attack

The Terrapin attack is not just a theoretical threat. It is a real and dangerous attack that can compromise the security of your SSH connections and expose your sensitive data. The consequences of a successful Terrapin attack can be severe, such as:

  • Data breaches: The attacker can access your confidential information, such as passwords, keys, files, or commands, and use them for malicious purposes.
  • Financial losses: The attacker can cause damage to your systems, services, or assets, and demand ransom or extort money from you.
  • Reputation damage: The attacker can leak your data to the public or to your competitors, and harm your credibility or trustworthiness.

Therefore, it is important to be aware of the Terrapin attack and take the necessary measures to prevent it. In the following sections, we will show you how the Terrapin attack works, how to protect yourself from it, and how to use PassCypher HSM PGP and EviKey NFC HSM to enhance the security of your SSH keys.

A prefix truncation attack on the SSH protocol

The Terrapin attack is a prefix truncation attack that targets the SSH protocol. It exploits a deficiency in the protocol specification, namely not resetting sequence numbers and not authenticating certain parts of the handshake transcript. By carefully adjusting the sequence numbers during the handshake, an attacker can remove an arbitrary amount of messages sent by the client or server at the beginning of the secure channel without the client or server noticing it.

This manipulation allows the attacker to perform several malicious actions, such as:

  • Downgrade the connection’s security by forcing it to use less secure client authentication algorithms
  • Bypass the keystroke timing obfuscation feature in OpenSSH, which may allow the attacker to brute-force SSH passwords by inspecting the network packets
  • Exploit vulnerabilities in SSH implementations, such as AsyncSSH, which may allow the attacker to sign a victim’s client into another account without the victim noticing

To pull off a Terrapin attack, the attacker must already be able to intercept and modify the data sent from the client or server to the remote peer. This makes the attack more feasible to be performed on the local network.

Unveiling the SSH Handshake: Exposing the Terrapin Attack’s Weakness

The SSH Handshake Process

The SSH handshake is a crucial process that establishes a secure channel between a client and server. It consists of the following steps:

  1. TCP connection establishment: The client initiates a TCP connection to the server.
  2. Protocol version exchange: The client and server exchange their protocol versions and agree on a common one. Then, the algorithm negotiation takes place.
  3. Algorithm negotiation: The client and server exchange lists of supported algorithms for key exchange, encryption, MAC, and compression. Then, they select the first matching algorithm.
  4. Key exchange: The client and server use the agreed-upon key exchange algorithm to generate a shared secret key. They also exchange and verify each other’s public keys. Then, the service request is sent.
  5. Service request: The client requests a service from the server, such as ssh-userauth or ssh-connection. Then, the client authenticates itself to the server using a supported method, such as password, public key, or keyboard-interactive.
  6. User authentication: The client authenticates itself to the server using a supported method, such as password, public key, or keyboard-interactive. Then, the channel request is sent.
  7. Channel request: The client requests a channel from the server, such as a shell, a command, or a subsystem. Thus, encrypted communication is enabled.

The Terrapin Attack

The Terrapin attack exploits a vulnerability in the SSH handshake by manipulating the sequence numbers and removing specific messages without compromising the secure channel integrity. This stealthy attack is difficult to detect because it doesn’t alter the overall structure or cryptographic integrity of the handshake.

For example, the attacker can eliminate the service request message sent by the client, which contains the list of supported client authentication methods. This forces the server to resort to the default method, typically password-based authentication. The attacker can then employ keystroke timing analysis to crack the password.

Alternatively, the attacker can target the algorithm negotiation message sent by the server, which lists the supported server authentication algorithms. By removing this message, the attacker forces the client to use the default algorithm, usually ssh-rsa. This opens the door for the attacker to forge a fake public key for the server and deceive the client into accepting it.

To illustrate the process of a Terrapin attack, we have created the following diagram:

Hackers exploit OAuth2 flaw to bypass 2FA on google accounts google account security flaw
Hackers exploit OAuth2 flaw to bypass 2FA on google accounts google account security flaw

As you can see, the diagram shows the steps from the interception of the communication by the attacker to the injection of malicious packets. It also highlights the stealthiness and the difficulty of detection of the attack.

Summery

The Terrapin attack is a serious threat to SSH security. By understanding how it works, you can take steps to protect yourself from it. Here are some tips:

  1. Make sure your SSH server is up to date with the latest security patches.
  2. Use strong passwords or public key authentication.
  3. Enable SSH key fingerprint verification.

How to protect yourself from the Terrapin attack: Best practices and tools

The Terrapin attack is a serious threat to SSH security, and it affects many SSH client and server implementations, such as OpenSSH, PuTTY, FileZilla, and more. Here are some steps you can take to protect yourself from it:

  • Update your SSH client and server to the latest versions. Many vendors have released patches that fix the vulnerability or introduce a strict key exchange option that prevents the attack. You can check if your SSH software is vulnerable by using the Terrapin vulnerability scanner.
  • Use strong passwords and public key authentication. Avoid using weak or default passwords that can be easily guessed by the attacker. Use public key authentication instead of password authentication, and make sure your public keys are verified and trusted.
  • Use secure encryption modes. Avoid using vulnerable encryption modes, such as ChaCha20-Poly1305 or AES-CBC with default MACs. Use encryption modes that use authenticated encryption with associated data (AEAD), such as AES-GCM or Chacha20-Poly1305@openssh.com.
  • Use a VPN or a firewall. If possible, use a VPN or a firewall to encrypt and protect your SSH traffic from being intercepted and modified by the attacker. This will also prevent the attacker from performing other types of attacks, such as DNS spoofing or TCP hijacking.
  • Implement a strict security policy on your local networks. Limit the access to your SSH servers to authorized users and devices, and monitor the network activity for any anomalies or intrusions.

Telegram and the Information War in Ukraine written by Jacques Gascuel, inventor of sensitive data safety and security systems, for Freemindtronic. This article may be updated on this subject.

How Telegram Shapes the Information War in Ukraine

In this article, we explore how Telegram and Ukraine’s information warfare are intertwined. We look at how the messaging app is influencing the Russia-Ukraine conflict, and how it can be used for good or evil. We also discuss the benefits and risks of using Telegram, as well as how security and freedom of expression can be enhanced with EviCypher NFC HSM technology.

How Telegram Influences the Conflict between Russia and Ukraine

Telegram and the information war in Ukraine are closely related. Telegram is a messaging app that offers users a secure and confidential way to communicate, thanks to its end-to-end encryption system. It has a large user base around the world, especially in Eastern Europe, where it plays a vital role in the information war between Russia and Ukraine.

Telegram’s Usage in Ukraine: Updated Statistics

Popularity and Download Trends

According to the report of the research company SimilarWeb, Telegram is the second most downloaded messaging app in Ukraine, after Viber, with 3.8 million downloads in 2021. It is also the fourth most used app in terms of time spent, with an average of 16 minutes per day. Telegram has about 10 million active users in Ukraine, which is almost a quarter of the country’s population.

Telegram’s Role in Ukrainian Media Landscape

Telegram is particularly appreciated by Ukrainians for its channel functionality, which allows to broadcast messages to a large audience. Some of these channels have become influential but controversial sources of information, as their owners and sources are often unknown. Among the most popular channels in Ukraine, we can mention:

  • @Zelenskyi, the official channel of President Volodymyr Zelensky, which has more than 2 million subscribers. It publishes announcements, speeches, interviews and videos of the head of state. It was created in 2019, during Zelensky’s election campaign, who was then an actor and a comedian.
  • @NashyGroshi, the channel of the journalistic project “Our Money”, which has more than 1.5 million subscribers. It publishes investigations, reports and analyses on corruption, abuse of power, political scandals and judicial cases in Ukraine. It was created in 2008, by journalist Denys Bihus, who received several awards for his work.
  • @Resident, the channel of blogger and activist Anatoliy Shariy, which has more than 1.3 million subscribers. It publishes comments, criticisms and sarcasms on the political and social news in Ukraine. He is known for his pro-Russian, anti-European and anti-government positions. He is currently in exile in Spain, where he is wanted by the Ukrainian justice for high treason and incitement to hatred.

These channels illustrate the diversity and complexity of the Ukrainian media landscape, which is marked by the conflict with Russia, the democratic transition, the fight against corruption and the polarization of society. They are also a reflection of the issues and challenges related to the use of Telegram, which can be both a tool of communication, information and manipulation.

Oleksiy Danilov’s Stance on Telegram’s Usage in Ukraine

Concerns Over National Security

Oleksiy Danilov is the secretary of the National Security and Defense Council of Ukraine, the body responsible for coordinating and controlling the activities of the executive bodies in the fields of national security and defense. He is also the head of cybersecurity of the country, and in this capacity, he expressed his reservations about the use of Telegram by Ukrainians. In February 2022, he stated that some anonymous and manipulative Telegram channels represented a threat to national security, and that they should be de-anonymized and regulated. He particularly targeted the channel @Resident, which broadcasts pro-Russian and anti-Ukrainian comments, and which is suspected of being linked to the Russian intelligence services. He also criticized the channel @Zelenskyi, which according to him, is not controlled by the Ukrainian president, but by advisers who seek to influence his policy.

Debating Telegram’s Influence in Ukraine

These statements provoked mixed reactions in Ukraine. Some supported Danilov’s position, believing that it was necessary to fight against misinformation and propaganda that undermine the sovereignty and democracy of the country. Others denounced an attempt at censorship and an attack on freedom of expression, recalling that Telegram was one of the few spaces where Ukrainians could access independent and diverse information.

Telegram is a messaging app that lets you send messages, photos, videos, documents, and make voice and video calls. Its privacy policy is based on data encryption and non-cooperation with authorities. You can also create groups and channels that can reach thousands or millions of users.

End-to-end encryption is a technology that makes sure only the people in a conversation can read the messages, not even the service provider. Telegram has this option, but it is not on by default. You have to choose it for each chat, by switching to the “secret chat” mode. However, Telegram’s encryption is not based on standard protocols, and security experts have found some flaws.

Anonymous Channels and Their Impact on the Ukrainian Conflict

The channels are spaces where an administrator can send messages to a large audience. They can be public or private, and they can have millions of followers. Some channels are influential but controversial sources of information, as their owners and sources are often unknown. The channels can spread misinformation, propaganda, fake news, or violence.

Telegram and Russian propaganda have a strong connection, as many pro-Russian channels use the app to influence the public opinion in Ukraine and other countries. Telegram and the Ukrainian resistance also use the app to communicate and organize their actions against the Russian aggression.

Bots, Payment Services and Unique Usernames: A Double-Edged Sword

Bots are programs that interact with users. They offer services, information, or entertainment. Anyone can create them. They can be part of chats or channels. Bots can be helpful or harmful. They can collect personal data, send spam, or spread viruses.

Payment Services: Handy or Dishonest?

You can also use payment services via Telegram. These features use third-party platforms, such as Stripe or Apple Pay. They need bank or credit card information. Payment services can be handy or dishonest. They can steal sensitive data, scam users, or fund illegal activities.

Unique Usernames: Fun or Troublesome?

Another feature of Telegram is the unique usernames. They let users contact each other easily, without sharing their phone number. Users can create and change them at any time. Unique usernames can be fun or troublesome. They can enable harassment, identity theft, or account sale.

These features of Telegram raise issues of cybersecurity, privacy, end-to-end encryption, and application security. They can be used by bad actors, who want to harm Ukraine or its people. They can also be regulated by the authorities, who want to control the information or access the data of the users.

Telegram and the Information War in Ukraine: A Challenge

One of the main challenges of Telegram and the information war in Ukraine is to balance the freedom of expression and the protection of national security. Telegram and the Ukrainian conflict are closely intertwined. The app is used by both sides to communicate, inform, and influence. Telegram and Russian propaganda have a strong connection. Many pro-Russian channels use the app to sway the public opinion in Ukraine and other countries. Telegram and the Ukrainian resistance also use the app to coordinate and organize their actions against the Russian aggression. Telegram and cybersecurity in Ukraine are also crucial. The app can be a source of threats or a tool of defense.

Telegram VS Other Messaging Apps: A Comparative Analysis

WhatsApp: Popular but Questionable Confidentiality

WhatsApp is the most popular messaging app in the world, with more than 2 billion users. It offers end-to-end encryption by default for all conversations, which guarantees the protection of data. However, it belongs to Facebook, which has a dubious reputation in terms of respect for privacy, and which has raised fears about the sharing of data with other applications of the group. WhatsApp is also subject to the requests of the authorities, who can demand access to the metadata, such as the phone number, the IP address or the location of the users.

Signal: High Security but Limited User Base

Signal is a messaging app that claims to be the most secure and confidential on the market. It also offers end-to-end encryption by default for all conversations, and it does not collect any personal data. It is developed by a non-profit organization, which does not depend on advertising or investors. It is recommended by personalities such as Edward Snowden or Elon Musk. Signal is however less popular than WhatsApp or Telegram, with about 50 million users. It also offers fewer features, such as file sharing, information channels, bots or payment services.

Telegram: Innovative but Security Concerns

Telegram is between these two apps, offering more features than Signal, but less security than WhatsApp. Telegram allows users to choose the level of encryption and privacy they want, by opting for the “secret chat” mode or the “normal chat” mode. Telegram also allows users to enjoy innovative services, such as channels, bots, payments or unique usernames. However, Telegram also presents risks, such as fakes news, inappropriate content, privacy breaches or cyberattacks. Telegram is therefore an app that offers advantages and disadvantages, and that requires vigilance and discernment from users.

Telegram’s Global Perception and Regulation

Russia: Origin and Opposition

Russia is the country of origin of Telegram, but also its main adversary. The Kremlin tried to block the app in 2018, invoking reasons of national security and fight against terrorism. It demanded that Telegram provide it with the encryption keys to access the messages of the users, which Pavel Durov refused. It then ordered the telecom operators to block access to Telegram, but this measure proved ineffective, as Telegram used cloud servers to bypass the blocking. Many Russian users also use VPNs or proxies to access the app. In 2020, the Kremlin finally lifted the ban on Telegram, acknowledging its failure and stating that the app had cooperated with the authorities to remove extremist content. However, some observers suspect that Telegram made concessions to the Kremlin to lift the blocking, such as collaborating with the Russian services or censoring some channels.

France: Striving for Digital Regulation

France is a country that wants to be at the forefront of the regulation of digital platforms, especially in terms of fighting online hate. It adopted in 2020 a law that obliges the platforms to remove illegal content, such as incitement to violence, discrimination or terrorism, within 24 hours, under penalty of financial sanctions. This law also applies to messaging apps, such as Telegram, which must set up reporting and moderation mechanisms for content. France recognizes the right of users to privacy and end-to-end encryption, but it also asks the service providers to cooperate with the law enforcement to access the encrypted data when needed. France is also a country where Telegram is used by radical groups, such as jihadists or yellow vests, who take advantage of the app to organize, mobilize or defend themselves.

Ukraine: Balancing Utility and Risks

Ukraine is a country that has an ambivalent attitude towards Telegram, recognizing its usefulness, but also its dangers. On the one hand, Telegram is a source of information and a tool of resistance for many Ukrainians, who face the threat of Russian aggression and the challenges of democratic transition. On the other hand, Telegram is also a vector of misinformation and propaganda, which can undermine the sovereignty and stability of the country. Ukraine does not have a specific law to regulate Telegram, but it has some legal provisions to protect national security and public order, which can be used to restrict or block the app if necessary. Ukraine also cooperates with international organizations, such as the EU or NATO, to counter the cyber threats and the hybrid warfare that target the country.

EviCypher NFC HSM: Enhancing Telegram’s Security

The Role of Contactless Encryption Technology

One of the main challenges of using Telegram is to ensure the security and confidentiality of the data exchanged, especially in a context of information war. To meet this challenge, a possible solution consists of using EviCypher NFC HSM technology, which is a contactless encryption technology developed by Freemindtronic, an Andorran company specializing in the design of counter-espionage solutions implementing in particular contactless security with NFC technology. EviCypher NFC HSM uses two types of encryption algorithms for data:

  • Symmetric encryption in AES-256 for data such as texts (messages), thanks to its sub-technology EviCrypt. It uses a unique key, which is randomly generated and segmented into several parts. This key is used to encrypt and decrypt messages with the AES 256-bit algorithm.
  • Asymmetric encryption in RSA-4096 for symmetric encryption keys. It uses a pair of keys, which is generated and used from the NFC HSM device and which is based on the RSA 4096-bit algorithm. This pair of keys is used to share the symmetric key of at least 256 bits between the NFC HSM devices remotely, by encrypting the symmetric key with the public key of the recipient and decrypting the symmetric key with the private key of the recipient. The symmetric key is then stored and re-encrypted in the NFC HSM device of the recipient, with the trust criteria imposed by the sender if he has encapsulated them in the shared encryption key.

Practical Applications of EviCypher NFC HSM

EviCypher NFC HSM is a technology that uses hardware security modules (HSM) to store and use encrypted secrets. It allows contactless encryption with the NFC communication protocol. You can integrate the NFC HSM into various media, such as a card, a sticker, or a key ring. Then, you can pair it with an NFC phone, tablet, or computer. This way, you can encrypt everything before using any messaging service, including Telegram. EviCypher NFC HSM also has anti-cloning, anti-replay, and counterfeit detection mechanisms. It is part of the DataShielder product range, which offers serverless and databaseless encryption solutions.

Telegram and the Ukrainian conflict

EviCypher NFC HSM is compatible with Telegram, a messaging app that influences the information war between Russia and Ukraine. It offers more security and confidentiality than Telegram’s end-to-end encryption, which is not based on recognized standards. It also gives you more flexibility and control than Telegram’s secret chat mode, as you can choose the trust criteria for the encryption keys. Moreover, it is more convenient and simple than Telegram’s normal chat mode, as you can encrypt and decrypt messages with a simple gesture.

Telegram and cybersecurity in Ukraine

EviCypher NFC HSM is a useful technology with Telegram, as it enhances the security and confidentiality of the data exchanged, especially in a context of information war. It is also a universal technology, as you can use it with any other messaging app, such as WhatsApp, Signal, Messenger, etc. It is also an innovative technology, as it uses the NFC communication protocol to perform contactless encryption, without requiring any connection or installation.

Kismet iPhone and Pegasus: a deadly combo

Hackers can use Kismet iPhone to install Pegasus spyware on your iPhone. This spyware can access your data, activity, and conversations.

Kismet iPhone: How to protect your device from the most sophisticated spying attack using Pegasus spyware

Do you own an iPhone? Do you think it is safe and private? You might be wrong. Hackers have created a clever attack called Kismet iPhone that can infect your device with Pegasus, the world’s most powerful spyware, without you noticing. This spyware can steal your personal data, track your activity, and listen to your conversations. In this article, we will tell you how Kismet iPhone works, who is behind it, and how you can protect yourself from it.

What is Kismet iPhone?

Kismet iPhone is the name of the attack that hackers use to install Pegasus, the spyware, on iPhones. Kismet iPhone uses a technique called “watering hole”. It consists of infecting websites visited by the targeted users. These websites contain malicious code that detects if the user has an iPhone and which model. If so, the malicious code redirects the browser to a server that exploits zero-day flaws in iOS and Safari. These flaws allow to install Pegasus without the user noticing. Pegasus then runs in the background and communicates with a command and control server.

What is Pegasus?

Pegasus is the name of the spyware that Kismet iPhone installs on iPhones. Pegasus is one of the most powerful spyware in the world, developed by NSO Group, an Israeli company that sells spyware to governments and intelligence agencies. Pegasus can access almost everything on the infected iPhone, such as messages, photos, contacts, location, calls, passwords and even conversations near the microphone. Pegasus can also activate the camera and the microphone remotely, and record the screen. Pegasus can bypass encryption and security features of apps like WhatsApp, Signal, Telegram, and others.

Who is behind Kismet iPhone and Pegasus?

Kismet iPhone and Pegasus are the work of NSO Group, an Israeli company that sells spyware to governments and intelligence agencies. NSO Group claims that its products are only used for legitimate purposes, such as fighting terrorism and crime. However, investigations have revealed that NSO Group has also targeted journalists, activists, lawyers, politicians and dissidents, violating their privacy and rights. NSO Group has been accused of being involved in the murder of Jamal Khashoggi, a Saudi journalist, and the hacking of Jeff Bezos, the founder of Amazon.

Examples of victims of Kismet iPhone and Pegasus

According to a report by Citizen Lab, a research group at the University of Toronto, Kismet iPhone and Pegasus have been used to spy on at least nine Bahraini activists between June 2020 and February 2021. The activists were members of the Bahrain Center for Human Rights, the Bahrain Institute for Rights and Democracy, and the European Center for Constitutional and Human Rights. They received text messages containing malicious links that attempted to infect their iPhones with Pegasus.

Another report by Amnesty International and Forbidden Stories, a non-profit media organization, revealed that Kismet iPhone and Pegasus have been used to target more than 50,000 phone numbers of people from various countries and professions. Among them were journalists, human rights defenders, lawyers, politicians, business executives, religious leaders, and celebrities. Some of the prominent names on the list were French President Emmanuel Macron, Pakistani Prime Minister Imran Khan, Indian opposition leader Rahul Gandhi, Moroccan journalist Omar Radi, and Mexican journalist Cecilio Pineda Birto.

A third report by The Guardian, a British newspaper, exposed that Kismet iPhone and Pegasus have been used to spy on the civil rights movement in the United States. The report found that at least 15 people who were close to the Black Lives Matter activist DeRay Mckesson had their phones hacked with Pegasus in 2016. The report also found that Alaa Mahajna, a lawyer who represented the family of George Floyd, had his phone hacked with Pegasus in 2020.

These examples show that Kismet iPhone and Pegasus are not only used to spy on criminals and terrorists, but also on innocent people who exercise their rights to freedom of expression, association, and assembly.

How to protect yourself from Kismet iPhone and Pegasus?

To protect yourself from Kismet iPhone and Pegasus, you need to update your iPhone with the latest version of iOS. Apple fixed the zero-day flaws exploited by Kismet iPhone in September 2020, making the attack ineffective. You also need to avoid clicking on suspicious links or visiting unsecured websites, which could be infected by malicious code. You need to use a VPN (virtual private network) to encrypt your internet connection and prevent potential spies from seeing your online activity. You can check if your iPhone has been infected by Pegasus by using a tool developed by Amnesty International, called MVT (Mobile Verification Toolkit).

Sources and downloads

If you want to learn more about the zero-day flaws used by Kismet iPhone and Pegasus, and how Apple fixed them, you can check the following sources:

If you want to check if your iPhone has been infected by Pegasus, you can download the following application:

The American Intelligence: How It Works, Its Limits and Consequences

The American intelligence is one of the most powerful and influential in the world. It has a vast network of agencies, resources, and allies that enable it to collect, analyze, and act on information of strategic interest. However, the American intelligence also faces challenges and criticisms, both internally and externally. In this article, we will explore how the American intelligence works, what are its limits, and what are the consequences of its actions for the global security and privacy.

How the American Intelligence Works

The American intelligence is composed of 18 agencies that form the Intelligence Community (IC). These agencies are divided into two categories: the civilian agencies, which are under the supervision of the Director of National Intelligence (DNI), and the military agencies, which are under the supervision of the Secretary of Defense.

The main civilian agencies are:

  • The Central Intelligence Agency (CIA), which is responsible for collecting, analyzing, and disseminating foreign intelligence, as well as conducting covert operations and paramilitary activities.
  • The National Security Agency (NSA), which is responsible for collecting, processing, and disseminating signals intelligence (SIGINT), as well as conducting cyber operations and protecting the US government’s communications and information systems.
  • The Federal Bureau of Investigation (FBI), which is responsible for collecting, analyzing, and disseminating domestic intelligence, as well as conducting counterintelligence, counterterrorism, and law enforcement activities.
  • The National Geospatial-Intelligence Agency (NGA), which is responsible for collecting, analyzing, and disseminating geospatial intelligence (GEOINT), which includes imagery, maps, and other geographic information.
  • The National Reconnaissance Office (NRO), which is responsible for designing, launching, and operating reconnaissance satellites and other space-based systems that provide intelligence to the IC and the Department of Defense (DoD).
  • The Office of the Director of National Intelligence (ODNI), which is responsible for overseeing, coordinating, and integrating the activities of the IC, as well as providing strategic guidance and support to the DNI.

The main military agencies are:

  • The Defense Intelligence Agency (DIA), which is responsible for providing military intelligence to the DoD and the IC, as well as conducting human intelligence (HUMINT), counterintelligence, and defense attaché activities.
  • The National Security Agency/Central Security Service (NSA/CSS), which is responsible for providing SIGINT and cyber support to the DoD and the IC, as well as conducting information assurance and cryptologic activities.
  • The National Geospatial-Intelligence Agency (NGA), which is responsible for providing GEOINT support to the DoD and the IC, as well as conducting geospatial analysis and mapping activities.
  • The National Reconnaissance Office (NRO), which is responsible for providing space-based intelligence support to the DoD and the IC, as well as conducting satellite reconnaissance and surveillance activities.
  • The Military Intelligence Corps (MI), which is responsible for providing tactical and operational intelligence to the Army and the joint force, as well as conducting HUMINT, SIGINT, GEOINT, and counterintelligence activities.
  • The Office of Naval Intelligence (ONI), which is responsible for providing maritime intelligence to the Navy and the joint force, as well as conducting HUMINT, SIGINT, GEOINT, and counterintelligence activities.
  • The Marine Corps Intelligence Activity (MCIA), which is responsible for providing intelligence to the Marine Corps and the joint force, as well as conducting HUMINT, SIGINT, GEOINT, and counterintelligence activities.
  • The Air Force Intelligence, Surveillance, and Reconnaissance Agency (AFISRA), which is responsible for providing intelligence to the Air Force and the joint force, as well as conducting HUMINT, SIGINT, GEOINT, and counterintelligence activities.

The American intelligence works by collecting information from various sources, such as human sources, signals, images, open sources, and others. It then analyzes this information to produce intelligence products, such as reports, assessments, briefings, and forecasts. These products are then disseminated to the relevant consumers, such as the President, the Congress, the military, the policy makers, and the allies. The American intelligence also acts on the information it collects, by conducting operations, such as covert actions, cyber attacks, drone strikes, and special operations.

The Limits of the American Intelligence

The American intelligence, despite its capabilities and resources, is not omnipotent or infallible. It faces several limits and challenges, such as:

  • Legal and ethical limits: The American intelligence is bound by the laws and regulations of the US and the international community, as well as by the values and principles of the American democracy. It must respect the rights and liberties of the American citizens and the foreign nationals, as well as the sovereignty and interests of the other countries. It must also abide by the oversight and accountability mechanisms of the executive, the legislative, and the judicial branches, as well as the public opinion and the media. The American intelligence must balance its need for secrecy and effectiveness with its duty for transparency and legitimacy.
  • Technical and operational limits: The American intelligence is limited by the availability and reliability of the information it collects, as well as by the accuracy and timeliness of the analysis it produces. It must deal with the challenges of information overload, data quality, data security, data privacy, and data sharing. It must also cope with the threats and risks of cyber attacks, counterintelligence, deception, and denial. The American intelligence must balance its need for innovation and adaptation with its need for standardization and coordination.
  • Strategic and political limits: The American intelligence is limited by the complexity and uncertainty of the global environment, as well as by the diversity and dynamism of the actors and issues it faces. It must deal with the challenges of globalization, multipolarity, regionalization, and fragmentation. It must also cope with the threats and opportunities of terrorism, proliferation, rogue states, failed states, and emerging powers. The American intelligence must balance its need for anticipation and prevention with its need for reaction and intervention.

The Consequences of the American Intelligence

The American intelligence has significant consequences for the global security and privacy, both positive and negative, such as:

  • Positive consequences: The American intelligence contributes to the protection and promotion of the national security and interests of the US and its allies, as well as to the maintenance and enhancement of the international peace and stability. It provides valuable information and insights to the decision makers and the operators, as well as to the public and the media. It also conducts effective operations and actions to deter, disrupt, or defeat the adversaries and the threats. The American intelligence plays a key role in the global intelligence cooperation and coordination, as well as in the global governance and leadership.
  • Negative consequences: The American intelligence also poses risks and challenges to the security and privacy of the US and its allies, as well as to the international order and norms. It may collect, analyze, or disseminate information that is inaccurate, incomplete, or biased, leading to errors, failures, or controversies. It may also conduct operations or actions that are illegal, unethical, or counterproductive, leading to violations, scandals, or backlashes. The American intelligence may face competition or conflict with the other intelligence services or actors, as well as with the other stakeholders or interests.

Section 702 of FISA: A Surveillance Without Control

  • On July 17, 2008, the US Congress passed section 702 of the FISA (Foreign Intelligence Surveillance Act), which authorizes the US intelligence agencies to collect the electronic communications of non-Americans located abroad, without a warrant from the FISA judge.
  • On January 19, 2018, the US Congress extended section 702 of FISA until December 31, 2023, without making any substantial changes.
  • On March 22, 2023, the US Congress extended section 702 of FISA again until April 19, 2024, without making any significant changes.
  • On December 16, 2023, the US Congress approved the National Defense Authorization Act (NDAA), which included a four-month extension of section 702 of FISA, avoiding its expiration at the end of the year.

The Violation of the Right to Privacy

  • On June 5, 2013, the whistleblower Edward Snowden revealed the existence of the PRISM program, which allowed the US intelligence agencies to access the data of the users of the main electronic service providers, such as Google, Facebook, Microsoft or Apple.
  • On October 6, 2015, the Court of Justice of the European Union (CJEU) invalidated the Safe Harbor, an agreement that allowed the transfer of personal data between the European Union and the United States, considering that it did not offer an adequate level of protection.
  • On July 16, 2020, the CJEU invalidated the Privacy Shield, the successor of the Safe Harbor, for the same reasons, considering that the risk of interference by the US intelligence services in the transferred data was incompatible with the respect of the fundamental rights of the persons concerned.
  • On July 31, 2023, the CJEU issued a ruling that confirmed the invalidity of the Privacy Shield and imposed strict conditions for the transfer of personal data to third countries, especially the United States, under the standard contractual clauses (SCCs) or the binding corporate rules (BCRs).

The Legal and Political Consequences

  • On October 24, 2013, the European Parliament adopted a resolution that condemned the massive surveillance activities of the US intelligence services and called for the suspension of the cooperation agreements on security and counter-terrorism.
  • On October 23, 2015, the European Parliament adopted another resolution that requested the creation of an independent international tribunal to examine the complaints of the European citizens regarding the surveillance of the US intelligence services.
  • On September 14, 2018, the European Parliament adopted a third resolution that called for the suspension of the Privacy Shield, due to the non-compliance of the commitments made by the United States on the protection of personal data.
  • On August 31, 2023, the European Parliament adopted a fourth resolution that asked the European Commission to propose a new legislation on the protection of personal data in the context of cross-border data flows, which would guarantee a level of protection equivalent to that of the general data protection regulation (GDPR).

New technologies and products that limit the possibilities of intelligence

Facing the capabilities of collection and analysis of the American intelligence, which threaten the privacy and sovereignty of individuals and countries, there are new technologies and products that allow to limit the possibilities of intelligence. These technologies and products use techniques of encryption, cryptography, blockchain or NFC to protect personal data and electronic communications. They offer an alternative to traditional solutions, which are often vulnerable to attacks or interceptions by the American intelligence. Among these technologies and products, we can mention:

  • EviCypher NFC HSM and EviCypher HSM OpenPGP, which are patented technologies in the United States in the field of cybersecurity developed by Freemindtronic SL Andorra, used in counter-espionage products such as DataShielder Defense. They allow to encrypt and decrypt data without contact, thanks to hardware security modules that use NFC technology. They offer compatibility with OpenPGP standards, operating without server, without database, with a very high level of flexibility from different removable, fixed and online and offline storage media including NFC HSM.
  • DataShielder DefenseDataShielder Defense, which is a counter-espionage product developed by Freemindtronic SL Andorra, which uses EviCore NFC HSM and EviCore HSM OpenPGP technologies to encrypt and decrypt all types of data and communication services. This product protects sovereign communications, by preventing the American intelligence from accessing personal, professional or state secrets. It also guarantees the sovereignty of users, by making their data anonymous and inviolable.
  • Signal, which is an instant messaging application that uses the Signal protocol, which is an end-to-end encryption protocol that ensures the confidentiality and integrity of messages. This application allows to communicate anonymously and securely, by avoiding the surveillance or censorship of the American intelligence.
  • Tor, which is a decentralized network that uses volunteer relays to route Internet traffic anonymously and encrypted. This network allows to browse the web without leaving traces, by hiding the IP address and location of users. It also allows to access hidden websites, which are not indexed by search engines.

These technologies and products represent examples of innovative solutions that limit the possibilities of the American intelligence and preserve the individual and collective sovereignty. They also illustrate the issues and challenges related to the use of digital technologies in the field of intelligence.

Conclusion

The American intelligence is a complex and dynamic phenomenon that has a significant impact on the world. It has many strengths and weaknesses, as well as many opportunities and threats. It has many achievements and failures, as well as many benefits and costs. It is a source of both security and insecurity, both privacy and surveillance. It is a subject of both admiration and criticism, both cooperation and confrontation. The American intelligence is a paradox that requires a careful and balanced approach.

This executive summary can be read in ≈ 3 to 4 minutes. It provides immediate insight into the central issue without requiring the full technical and historical analysis.

⚠️ Note on Supply Chain Resilience

The 2026 Global-e leak highlights what the CISA (Cybersecurity & Infrastructure Security Agency) defines as critical supply chain risks. According to their official guidelines, hardware security is only as strong as its weakest third-party link.

⚡ Key Findings

Since 2017, Ledger has faced several major breaches: seed phrase and firmware attacks, PCB modification, the 2020 database leak, the 2023 Connect Kit compromise, and the 2026 Global‑e data leak. These incidents show that threats arise not only from internal flaws but also from external dependencies and phishing vectors.

✦ Immediate Impact

  • Massive customer data exposure (292K in 2020, Global‑e in 2026)
  • Targeted phishing and harassment using personal information
  • Transaction manipulation and private-key compromise in controlled 2018 attack scenarios
  • Fragility of software supply chains and third‑party partners

⚠ Strategic Message

The real shift is not just technical compromise, but the repetition of breaches and their systemic exploitation. The threat becomes structural: automated phishing, doxxing, erosion of trust, and increased reliance on third parties. The risk is no longer occasional, but persistent.

The Shift from Trust to Proof

The repetition of Ledger Security Breaches proves that trust in a brand is not enough. Sovereignty requires proof. By implementing Segmented Key Authentication (WO2018154258), Freemindtronic moves control over critical secrets (seed phrases, private keys, credentials) from the vendor ecosystem directly into the user’s physical possession. This eliminates dependency on third-party infrastructure (e-commerce, update servers, logistics partners) for the custody and transfer of critical secrets.

⎔ Sovereign Countermeasure

There is no miracle solution against security breaches. Sovereignty means reducing exploitable surfaces: minimizing exposed data, using independent cold wallets (NFC HSM), strictly separating identity from usage, and maintaining constant vigilance against fraudulent communications.

The chronicles displayed above ↑ belong to the Digital Security section. They extend the analysis of sovereign architectures, data black markets, and surveillance tools. This selection complements the present chronicle dedicated to the **Ledger Security Breaches (2017–2026)** and the systemic risks linked to hardware vulnerabilities, supply‑chain compromises, and third‑party providers.

Advanced Summary

This advanced summary frames Ledger Security Breaches (2017–2026) through a systemic lens. It does not focus only on technical incidents, but analyzes the full dependency chain — firmware, software, partners, and customer data — and explains why certain architectures make these failures structural, not accidental.

A sequence of breaches that reveals a security-model problem

Since 2017, Ledger has faced a series of major incidents: seed phrase recovery attacks, firmware replacement, physical device modifications, application-level vulnerabilities (Monero), the massive 2020 customer database leak, the 2023 software supply-chain compromise, and the 2026 Global-e order-data leak. Taken separately, each event can be labeled an “incident.” Taken together, they reveal a security model problem.

The common denominator is not low-level cryptography, but the recurring necessity for critical secrets (seed phrases, private keys, identity-related metadata) to pass at some point through a non-sovereign environment: proprietary firmware, the host computer, connected applications, update servers, or an e-commerce partner.

From component security to ecosystem vulnerability

Ledger historically relied on the robustness of the hardware component itself. But from 2020 onward, the attack surface shifted to the peripheral ecosystem: customer databases, logistics services, software dependencies, user interfaces, notifications, and support channels.

The 2026 Global-e leak marks a turning point. Even without direct private-key compromise, exposure of delivery and order metadata turns users into persistent targets: ultra-targeted phishing, “delivery” social engineering, doxxing, and, in extreme cases, physical threats. Security is no longer only digital — it becomes civil and personal.

Why phishing and hybrid attacks become inevitable

Once a user’s real identity is correlated with crypto ownership, phishing stops being opportunistic. It becomes industrial and personalized.

BITB attacks, fake updates, fake delivery incidents, or “compliance” scams exploit less a technical bug than the human factor, made vulnerable by exposed metadata.

In this context, hardening firmware or adding software warnings is not sufficient. The problem is not cryptographic signing — it is that the secret or its holder becomes identifiable, traceable, or remotely reachable.

Paradigm shift: from trust to hardware proof

Facing these structural limits, some approaches do not attempt to strengthen transaction signing — they aim to remove critical secrets from any connected ecosystem. Freemindtronic’s sovereign alternatives follow the opposite logic: instead of securing a connected stack, they seek to radically reduce dependencies. NFC HSM devices are battery-less, cable-less, and network-port-less, requiring no account, no server, and no cloud synchronization.

This paradigm shift is embodied by air-gap secret sharing: critical secrets (seed phrases, private keys, credentials for hot wallets or proprietary systems) can be transferred hardware → hardware from one SeedNFC HSM to another, via an RSA-4096 encrypted QR code using the recipient’s public key — without blockchain, without server, and without any transaction-signing function.

A structural answer to the failures observed since 2017

Where Ledger failures rely on supply chains, updates, and commercial relationships, sovereign architectures remove these breaking points by design. There is nothing to hack remotely, nothing to divert in a cloud, and nothing to extract from a third-party server. Even if visually exposed, an encrypted QR code remains unusable without physical possession of the recipient HSM.

This model does not promise “magic” security. It imposes deliberate responsibility: irreversibility of transfers, physical control, and operational discipline. But it eliminates the systemic attack vectors that have repeatedly surfaced since 2017.

Ledger Security Breaches (2017–2026): How to Protect Your Cryptocurrencies

Have you ever questioned the real level of security protecting your digital assets?
If you use a Ledger device, you may assume your funds are safe from hackers. Ledger is a French company widely recognized for its role in cryptocurrency security, offering hardware wallets designed to isolate private keys from online threats.

However, since 2017, Ledger Security Breaches have repeatedly challenged this assumption. Over time, multiple vulnerabilities have emerged—some exposing personal data, others enabling private-key compromise only in specific, controlled attack scenarios (e.g., physical access or manipulated environments). These weaknesses have allowed attackers not only to steal funds, but also to exploit users through phishing, identity correlation, and targeted coercion.

This chronicle provides a structured analysis of the major Ledger security incidents from 2017 to 2026. It explains how each breach was exploited, what risks they introduced, and why certain architectural choices amplify systemic exposure. Most importantly, it outlines practical and strategic approaches to reduce attack surfaces and regain control over cryptographic sovereignty.

Rather than focusing on fear or isolated failures, this analysis aims to help users understand the evolving threat landscape—and to distinguish between trust-based security and proof-based, sovereign architectures.

Ledger security incidents: How Hackers Exploited Them and How to Stay Safe

Ledger security breaches have exposed logistical and relational metadata (delivery address, purchase history, identity correlation), and in specific historical attack scenarios, enabled the compromise of private keys under controlled conditions. Ledger is a French company that provides secure devices to store and manage your funds. But since 2017, hackers have targeted Ledger’s e-commerce and marketing database, as well as its software and hardware products. In this article, you will discover the different breaches, how hackers exploited them, what their consequences were, and how you can protect yourself from these threats.

Ledger Security Breaches (2017–2026): From Hardware Attacks to Systemic Supply-Chain Risk

Have you ever wondered how safe your cryptocurrencies are? If you are using a Ledger device, you might think that you are protected from hackers and thieves. Ledger is a French company that specializes in cryptocurrency security. It offers devices that allow you to store and manage your funds securely. These devices are called hardware wallets, and they are designed to protect your private keys from hackers and thieves.

However, since 2017, Ledger has been the target of multiple incidents that exposed logistical and relational metadata (delivery address, purchase history, identity correlation) and, in specific historical attack scenarios, enabled private-key compromise under controlled conditions. These breaches could allow hackers to steal your cryptocurrencies or harm you in other ways. In this article, we will show you the different breaches that were discovered, how they were exploited, what their consequences were, and how you can protect yourself from these threats.

Ledger Security Issues: The Seed Phrase Recovery Attack (February 2018)

The seed phrase is a series of words that allows you to restore access to a cryptocurrency wallet. It must be kept secret and secure, as it gives full control over the funds. In February 2018, a security researcher named Saleem Rashid discovered a breach in the Ledger Nano S, which allowed an attacker with physical access to the device to recover the seed phrase using a side-channel attack.

How did hackers exploit the breach?

The attack consisted of using an oscilloscope to measure the voltage variations on the reset pin of the device. These variations reflected the operations performed by the secure processor of the Ledger Nano S, which generated the seed phrase. By analyzing these variations, the attacker could reconstruct the seed phrase and access the user’s funds.

Simplified diagram of the attack

  • Date of discovery of the breach by Ledger: February 20, 2018
  • Author of the discovery of the breach: Saleem Rashid, a security researcher
  • Date of publication of the fix by Ledger: April 3, 2018

Scenarios of hacker attacks

  • Scenario of physical access: The attacker needs to have physical access to the device, either by stealing it, buying it second-hand, or intercepting it during delivery. The attacker then needs to connect the device to an oscilloscope and measure the voltage variations on the reset pin. The attacker can then use a software tool to reconstruct the seed phrase from the measurements.
  • Scenario of remote access: The attacker needs to trick the user into installing a malicious software on their computer, which can communicate with the device and trigger the reset pin. The attacker then needs to capture the voltage variations remotely, either by using a wireless device or by compromising the oscilloscope. The attacker can then use a software tool to reconstruct the seed phrase from the measurements.

Ledger Security Flaws: The Firmware Replacement Attack (March 2018)

The firmware is the software that controls the operation of the device. It must be digitally signed by Ledger to ensure its integrity. In March 2018, the same researcher discovered another breach in the Ledger Nano S, which allowed an attacker to replace the firmware of the device with a malicious firmware, capable of stealing the private keys or falsifying the transactions.

How did hackers exploit the Ledger Security Breaches?

The attack consisted of exploiting a vulnerability in the mechanism of verification of the firmware signature. The attacker could create a malicious firmware that passed the signature check, and that installed on the device. This malicious firmware could then send the user’s private keys to the attacker, or modify the transactions displayed on the device screen.

Ledger Security Incidents: The Printed Circuit Board Modification Attack (November 2018)

The printed circuit board is the hardware part of the device, which contains the electronic components. It must be protected against malicious modifications, which could compromise the security of the device. In November 2018, a security researcher named Dmitry Nedospasov discovered a breach in the Ledger Nano S, which allowed an attacker with physical access to the device to modify the printed circuit board and install a listening device, capable of capturing the private keys or modifying the transactions.

How did hackers exploit the breach?

The attack consisted of removing the case of the device, and soldering a microcontroller on the printed circuit board. This microcontroller could intercept the communications between the secure processor and the non-secure processor of the Ledger Nano S, and transmit them to the attacker via a wireless connection. The attacker could then access the user’s private keys, or modify the transactions displayed on the device screen.

Ledger Security Breaches: Monero Application Vulnerability (March 2019)

Not all cryptocurrencies interact with hardware wallets in the same way.
In March 2019, a critical vulnerability was discovered in the Monero (XMR) application for Ledger devices.
Unlike the 2018 physical attacks, this flaw was located in the communication protocol between the Ledger device and the Monero desktop client.

How Was the Vulnerability Exploited?

The flaw allowed a malicious or compromised Monero client to send manipulated transaction data to the Ledger device.

By exploiting a bug in the handling of change outputs, an attacker could:

  • redirect funds to an address under their control without the user noticing on the Ledger screen, or
  • under specific and controlled conditions, reconstruct the Monero private spend key by observing multiple device–host exchanges.

In this scenario, the hardware wallet signed cryptographically valid transactions based on manipulated inputs originating from the host software.

Infographic illustrating a Monero transaction hijack via a malicious GUI wallet despite the use of a Ledger hardware wallet.

Incident Summary

  • Potentially affected users: Monero (XMR) holders using Ledger Nano S or Nano X
  • Reported loss: One documented case of approximately 1,600 XMR (~USD 83,000 at the time)
  • Date of discovery: March 4, 2019
  • Discoverers: Monero community & Ledger Donjon
  • Patch released: March 6, 2019 (Monero app version 1.5.1)

Attack Scenarios

  • Compromised software: The user interacts with an infected or unofficial Monero GUI wallet. During a legitimate transaction, the client silently alters transaction parameters to drain funds.
  • Key reconstruction (controlled scenario): An attacker with malware on the host computer could theoretically reconstruct the Monero private spend key by intercepting and correlating multiple device–PC exchanges.

Important clarification: This incident did not involve a mass leak of private keys.
It demonstrated that, under specific conditions and with a compromised host environment, private key compromise was technically possible due to application-layer design flaws.

Structural “Blind Signing” Vulnerability: Signing in the Dark by Design (Permanent)

Blind Signing is not a temporary flaw nor a bug that can be patched with a firmware update.
It is a structural design limitation inherent to hardware wallets when confronted with the growing complexity of smart contracts.


As of 2026, it represents the #1 fund-theft vector in Web3, ahead of classic technical exploits.

Why Blind Signing Is Fundamentally Dangerous

A hardware wallet is supposed to enable conscious and verifiable validation of sensitive operations.
With Blind Signing, however, the device is unable to render the real intent of the contract being signed.

The user is typically presented with:

  • a generic “Data Present” message
  • unreadable hexadecimal strings
  • or a partial, non-human-interpretable description

The signature becomes an act of faith.
The user no longer validates a understood action, but complies with an opaque interface.

Diagram illustrating Blind Signing, showing a hardware wallet displaying 'Data Present' while a malicious smart contract drains funds.

Figure — Blind Signing: when the user signs a transaction whose real intent cannot be verified.

An Attack by Consent, Not by Circumvention

Unlike the 2018 Ledger incidents (seed recovery, firmware replacement, PCB modification),
Blind Signing does not attempt to break the hardware security.

It turns it against the user.

Everything is:

  • cryptographically valid
  • signed with the genuine private key
  • irreversible on the blockchain

There is no detectable malware, no key extraction, no firmware compromise.
The loss is legally and technically attributable to the signature itself.

Impact and Scope

  • Affected users: 100% of DeFi / NFT / Web3 users
  • Estimated losses: hundreds of millions of USD (cumulative)
  • Status: permanent and systemic risk
  • Root cause: inability to verify signed intent

Typical Attack Scenarios

  • Wallet drainers: a fake mint or airdrop leads to signing a contract that grants unlimited asset transfer rights.
  • Hidden infinite approvals: the user unknowingly signs a permanent authorization. The wallet is emptied later, without any further interaction.

Conclusion:
Blind Signing marks a critical rupture: the private key remains protected, but effective security disappears.

The question is no longer “Is my wallet secure?”, but:

“Am I able to prove what I am signing?”

Ledger Security Breaches: The Connect Kit Attack (December 2023)

The Connect Kit is a software that allows users to manage their cryptocurrencies from their computer or smartphone, by connecting to their Ledger device. It allows to check the balance, send and receive cryptocurrencies, and access services such as staking or swap.

The Connect Kit breach was discovered by the security teams of Ledger in December 2023. It was due to a vulnerability in a third-party component used by the Connect Kit. This component, called Electron, is a framework that allows to create desktop applications with web technologies. The version used by the Connect Kit was not up to date, and had a breach that allowed hackers to execute arbitrary code on the update server of the Connect Kit.

Technical validation: This type of supply chain attack is classified under CWE-494 (Download of Code Without Integrity Check). You can monitor similar hardware wallet vulnerabilities on the MITRE CVE Database.

How did hackers exploit the Ledger Security Breaches?

The hackers took advantage of this breach to inject malicious code into the update server of the Connect Kit. This malicious code was intended to be downloaded and executed by the users who updated their Connect Kit software. The malicious code aimed to steal the sensitive information of the users, such as their private keys, passwords, email addresses, or phone numbers.

Simplified diagram of the attack

Figure Ledger Security Breaches The Connect Kit Attack (December 2023)

Statistics on the breach

  • Number of potentially affected users: about 10,000
  • Total amount of potentially stolen funds: unknown
  • Date of discovery of the breach by Ledger: December 14, 2023
  • Author of the discovery of the breach: Pierre Noizat, director of security at Ledger
  • Date of publication of the fix by Ledger: December 15, 2023

Scenarios of hacker attacks

  • Scenario of remote access: The hacker needs to trick the user into updating their Connect Kit software, either by sending a fake notification, a phishing email, or a malicious link. The hacker then needs to download and execute the malicious code on the user’s device, either by exploiting a vulnerability or by asking the user’s permission. The hacker can then access the user’s information or funds.
  • Scenario of keyboard: The hacker needs to install a keylogger on the user’s device, either by using the malicious code or by another means. The keylogger can record the keystrokes of the user, and send them to the hacker. The hacker can then use the user’s passwords, PIN codes, or seed phrases to access their funds.
  • Scenario of screen: The hacker needs to install a screen recorder on the user’s device, either by using the malicious code or by another means. The screen recorder can capture the screen of the user, and send it to the hacker. The hacker can then use the user’s QR codes, addresses, or transaction confirmations to steal or modify their funds.

Ledger Security Breaches: The Data Leak (December 2020)

The database is the system that stores the information of Ledger customers, such as their names, addresses, phone numbers and email addresses. It must be protected against unauthorized access, which could compromise the privacy of customers. In December 2020, Ledger revealed that a breach in its database had exposed the logistical and relational metadata (delivery address, purchase history, identity correlation) of 292,000 customers, including 9,500 in France.

How did hackers exploit the breach?

The breach had been exploited by a hacker in June 2020, who had managed to access the database via a poorly configured API key. The hacker had then published the stolen data on an online forum, making them accessible to everyone. Ledger customers were then victims of phishing attempts, harassment, or threats from other hackers, who sought to obtain their private keys or funds.

Scenarios of hacker attacks

  • Scenario of phishing: The hacker sends an email or a text message to the user, pretending to be Ledger or another trusted entity. The hacker asks the user to click on a link, enter their credentials, or update their device. The hacker then steals the user’s information or funds.
  • Scenario of harassment: The hacker calls or visits the user, using their logistical and relational metadata (delivery address, purchase history, identity correlation) to intimidate them. The hacker threatens the user to reveal their identity, harm them, or steal their funds, unless they pay a ransom or give their private keys.
  • Scenario of threats: The hacker uses the user’s logistical and relational metadata (delivery address, purchase history, identity correlation) to find their social media accounts, family members, or friends. The hacker then sends messages or posts to the user or their contacts, threatening to harm them or expose their cryptocurrency activities, unless they comply with their demands.

Ledger Security Breaches: The Global-e Data Leak (January 2026)

In January 2026, Ledger disclosed a new breach caused by its e-commerce partner Global-e.
Attackers compromised Global-e’s cloud systems, exposing customer names, email addresses, and delivery contact details used for online orders.

Unlike previous incidents, no seed phrases, private keys, or payment card data were compromised.
However, this leak significantly increased the risk of targeted phishing, doxxing, and long-term social engineering attacks against Ledger customers.

Figure — Global-e 2026 breach: how exposed order data enables phishing, doxxing, and coercive targeting.
Active Defense: Mitigating Global-e Leak Risks

The SeedNFC HSM ecosystem, combined with PassCypher HSM PGP, provides a structural response by shifting security into the user’s physical control:

  • Reduced purchase metadata exposure: minimizing the collection and retention of identifiable data (name, address, phone) limits the long-term impact of e-commerce and logistics leaks such as 2020 and Global-e (2026).
  • Hardware-based intent validation: critical actions require a physical NFC interaction, rendering remote phishing and fake-support attacks ineffective after a data leak.
  • Anti-BITB & Anti-Iframe protection: blocks fake Ledger Live interfaces and credential-harvesting windows commonly used in post-leak phishing campaigns.
  • Compromised credential detection: checks whether emails or passwords have appeared in previous breaches, preventing reuse and account takeover.
Global-e Breach Statistics
  • Affected users: Not publicly disclosed (investigation ongoing as of January 2026).
  • Exposed data: Customer names, emails, and delivery contact information.
  • Impact on sensitive assets: None (private keys and funds remained secure).
  • Date of discovery: January 4, 2026.
  • Breach origin: Global-e cloud infrastructure.
⚠️ Critical Alert: Dark Web Resale & Persistent Targeting

A data breach is permanent. Once an identity is associated with a hardware wallet purchase,
the individual remains a high-value target for years.

Sovereign defense: By managing keys and credentials in a hardware-only environment such as SeedNFC HSM,
users can de-link their digital identity from centralized e-commerce databases and recurring leaks.

Escalation of Threats: From Delivery Phishing to Physical Coercion

The Global-e delivery-data leak does not merely enable email scams.
It fuels hybrid attacks where digital exposure transitions into real-world coercion.

“Delivery” Phishing: Precision Social Engineering

Attackers exploit order history to send ultra-credible SMS or emails:

  • Scenario: Fake courier messages (customs issue, address error, delayed shipment).
  • Trap: A cloned Ledger interface requesting a recovery phrase to “unlock” delivery.
  • Why it works: The victim is already expecting a shipment or update.

Physical Extortion & Home-Targeting

When physical addresses are exposed, the threat extends beyond cybercrime:

  • Targeted home visits: Criminal groups identify where crypto holders live.
  • Coercion: Victims are forced to sign irreversible transfers under threat.
  • Family pressure: Attacks may involve relatives to break resistance.

“A leaked Ledger delivery address acts as a marker: it tells criminals where the vault is and who holds the key.” This reality forces a fundamental rethink of how security tools are purchased and how identity is exposed.

Official Statements and Expert Sources

Global Reactions: Trust Erosion, Legal Pressure, and Community Backlash

The January 2026 Global-e order-data breach triggered a strong and immediate reaction across the global crypto ecosystem. Unlike earlier technical exploits, this incident reinforced a growing perception that the primary risk no longer lies in cryptography or hardware components, but in ecosystem-level dependencies: e-commerce partners, logistics providers, and identity-linked metadata.

Across English-speaking communities (Reddit, X, Discord, Telegram), the dominant sentiment was not surprise, but fatigue. For many users, Global-e represented the third major reminder—after 2020 and 2023—that hardware security alone does not guarantee user safety.

Recurring Themes in Anglophone Communities

  • Collapse of “secure-by-brand” trust: Ledger’s hardware is still widely perceived as technically robust, but confidence in the surrounding commercial and data-handling ecosystem has eroded.
  • Metadata as the real vulnerability: Users increasingly recognize that names, emails, delivery addresses, and purchase history enable profiling, targeting, and coercion—even when private keys remain secure.
  • Phishing industrialization: Highly personalized scams (fake delivery notices, fake compliance alerts, fake support cases) are now viewed as an unavoidable consequence of large-scale data leaks.

From Cybersecurity to Legal and Regulatory Exposure

In the United States, United Kingdom, and European Union, discussions rapidly shifted toward legal accountability and consumer protection, backed by official frameworks:

  • Class action risk (US / UK): Law firms are examining collective lawsuits for negligence and failure of duty of care, citing precedents in data breach litigation.
  • Regulatory scrutiny: Data-protection authorities like the CNIL (EU) and the ICO (UK) have emphasized strict third-party dependency management under GDPR.
  • Law-enforcement alerts: Agencies like Cybermalveillance.gouv.fr and the FBI (IC3) emphasize that crypto-related leaks increasingly enable hybrid crime, combining cyber-fraud with real-world intimidation.

Hybrid Threat Escalation: From Phishing to Physical Coercion

The Global-e breach illustrates a broader evolution of crypto-crime: the transition from purely digital theft to hybrid attack models, a trend confirmed by the INTERPOL Global Cybercrime reports.

Precision Phishing at Global Scale

Attackers leverage order metadata to craft highly credible messages. As reported by The Block, these campaigns include:

  • Fake courier notifications (customs delay, address issues)
  • Cloned Ledger Live portals requesting recovery phrases
  • Social-engineering scripts tailored to purchase history

Physical Targeting and Extortion Risks

Once physical addresses are exposed, risks extend beyond cybercrime, aligning with the Chainalysis Crypto Crime evolution analysis:

  • Home targeting: Criminal groups identify where high-value crypto holders live.
  • Forced transactions: Victims are coerced into signing irreversible transfers via physical threats.
  • Family leverage: Threats may extend to relatives to break resistance.

“A leaked delivery address does not steal funds—but it identifies the vault and the person holding the key.”

This realization has driven a growing demand for identity-minimizing, hardware-sovereign security models built on privacy-by-design principles —such as those prioritizing “Privacy by Design” by erasing all digital purchase records—to decouple asset protection from centralized logistics vulnerabilities.

Permanent Air-Gapped Secret Sharing: RSA-4096 Encrypted QR Between SeedNFC HSM Devices

SeedNFC implements a fully air-gapped secret-sharing mechanism based on an
RSA-4096 encrypted QR code using the recipient’s public key.
The recipient must be another SeedNFC HSM, ensuring that only that device can decrypt and
import the secret directly into hardware.

The QR code is only an encrypted transport container. It can be displayed locally, sent as an image,
or even shown during a video call. Without physical possession of the recipient SeedNFC HSM,
the content remains mathematically unusable.

  • Offline asymmetric encryption: the secret is never exposed in plaintext inside the QR code.
  • Zero infrastructure: no server, no account, no database, no cloud.
  • Operational + logical air-gap: sharing remains possible without any network connectivity.

This mechanism includes no revocation, no delay, and no expiration: the transfer is permanent by design.
It enables direct hardware → hardware transfer of critical secrets (seed phrases, private keys, access credentials)
between isolated HSM devices, with no software intermediary and no blockchain involvement.

Clarification: secret transfer ≠ transaction signing

SeedNFC HSM is not presented here as a transaction signer. Its role is upstream: to generate, store, and transfer secrets (seed phrases, private keys) or authentication data (IDs/passwords, hot-wallet access, proprietary systems) within a sovereign hardware boundary.

It can also store encrypted seed phrases from third-party wallets (Ledger, Trezor, software hot wallets, etc.) and their associated private keys, without depending on the original vendor’s firmware, software, or infrastructure.

Depending on the use case, data can be injected in a controlled way into an application field through Bluetooth HID keyboard emulation (e.g., migration, restore, login).

Web complement: for browser workflows, equivalent controlled input can be triggered via the Freemindtronic browser extension (explicit field selection). This eliminates exposure via clipboard, temporary files, or cloud sync, and strongly reduces risk from classic software keyloggers, since the user does not type anything.

Scope note: like any input, data may still become observable at the display point or on a compromised host (screen capture, application malware). The goal is to remove “copy/paste + file” vectors and human typing—not to make an infected system “invulnerable”.

Important: transferring a private key transfers ownership (full control over the associated funds).This is relevant for backup, migration, inheritance, or off-chain ownership transfer, but must be used with strict operational discipline.

Why this matters after data leaks: even if metadata is exposed, secrets can remain isolated and transferable without re-entering a connected vendor ecosystem.

Comparison with other crypto wallets

Ledger is not the only solution to secure your cryptocurrencies. There are other options, such as other hardware wallets, software wallets, or exchanges. Each option has its advantages and disadvantages, depending on your needs and preferences.

Other Hardware Wallets

For example, other hardware wallets, such as Trezor, offer similar features and security levels as Ledger, but they may have different designs, interfaces, or prices.

Software Wallets

Software wallets, such as Exodus or Electrum, are more convenient and accessible, but they are less secure and more vulnerable to malware or hacking.

Exchanges

Exchanges, such as Coinbase or Binance, are more user-friendly and offer more services, such as trading or staking, but they are more centralized and risky, as they can be hacked, shut down, or regulated.

Security Vector Traditional USB Wallet Freemindtronic NFC HSM
Physical Attack Surface High (USB ports, Battery, Screen) Minimal (No ports, No battery)
Data Persistence Risk of flash memory wear High (EviCore long-term integrity)
Side-Channel Leakage Possible (Power consumption analysis) Immune (Passive induction)

Cold Wallet Alternatives

Another option is to use a cold wallet, such as SeedNFC HSM, which is a patented HSM that uses NFC technology to create, store, and transfer cryptographic secrets (seed phrases, private keys, credentials) in an offline, hardware-only environment, without any connection to the internet or a computer. It also allows you to create up to 100 cryptocurrency wallets and check the balances from this NFC HSM.

Internationally Patented Sovereign Technology

To address the structural flaws identified in traditional hardware wallets, Freemindtronic uses a unique architecture protected by international patents (WIPO). These technologies ensure that the user remains the sole master of their security environment.

  • Access Control System Patent WO2017129887
    Guarantees physical-to-digital integrity by ensuring the HSM can only be triggered by a specific, intentional human action, preventing remote exploitation.
  • Segmented Key Authentication System Patent WO2018154258
    Provides a defense-in-depth mechanism where secrets are fragmented. This prevents a “single point of failure,” making “Connect Kit” type attacks or firmware replacements ineffective.

Technological, Regulatory, and Societal Projections

The future of cryptocurrency security is uncertain and challenging. Many factors can affect Ledger and its users, such as technological, regulatory, or societal changes.

Technological changes

It changes could bring new threats, such as quantum computing, which could break the encryption of Ledger devices, or new solutions, such as biometric authentication or segmented key authentication patented by Freemindtronic, which could improve the security of Ledger devices.

Regulatory changes

New rules or restrictions could affect Cold Wallet and Hardware Wallet manufacturers and users, such as Ledger. For example, KYC (Know Your Customer) or AML (Anti-Money Laundering) requirements could compromise the privacy and anonymity of Ledger users. They could also ban or limit the use of cryptocurrencies, which could reduce the demand and value of Ledger devices. On the other hand, other manufacturers who have anticipated these new legal constraints could have an advantage over Ledger. Here are some examples of regulatory changes that could affect Ledger and other crypto wallets:

  • MiCA, the proposed EU regulation on crypto-asset markets, aims to create a harmonized framework for crypto-assets and crypto-asset service providers in the EU. It also seeks to address the risks and challenges posed by crypto-assets, such as consumer protection, market integrity, financial stability and money laundering.The Markets in Crypto-Assets (MiCA) regulation, specifically Title V on service provider obligations, is now the gold standard. Freemindtronic technologies are designed to align with the Official Regulation (EU) 2023/1114, ensuring privacy while meeting compliance needs.
  • U.S. interagency report on stablecoins recommends that Congress consider new legislation to ensure that stablecoins and stablecoin arrangements are subject to a federal prudential framework. It also proposes additional features, such as limiting issuers to insured depository institutions, subjecting entities conducting stablecoin activities (e.g., digital wallets) to federal oversight, and limiting affiliations between issuers and commercial entities.
  • Revised guidance from the Financial Action Task Force (FATF) on virtual assets and virtual asset service providers (VASPs) clarifies the application of FATF standards to virtual assets and VASPs. It also introduces new obligations and recommendations for PSAVs, such as the implementation of the travel rule, licensing and registration of PSAVs, and supervision and enforcement of PSAVs.

These regulatory changes could have significant implications for Ledger and other crypto wallets. They could require them to comply with new rules and standards, to obtain new licenses or registrations, to implement new systems and processes, and to face new supervisory and enforcement actions.

Societal changes

Societal changes could influence the perception and adoption of Ledger and cryptocurrencies, such as increased awareness and education, which could increase the trust and popularity of Ledger devices, or increased competition and innovation, which could challenge the position and performance of Ledger devices. For example, the EviSeed NFC HSM technology allows the creation of up to 100 cryptocurrency wallets on 5 different blockchains chosen freely by the user.

Technological Alternatives for Absolute Sovereignty

The persistence of Ledger Security Breaches demonstrates that relying on a single centralized manufacturer creates a systemic risk. Today, decentralized alternatives developed by Freemindtronic in Andorra offer a paradigm shift: security based on hardware proof and physical intent, rather than brand trust.

Technologies such as EviCore NFC HSM and EviSeed NFC HSM are not just wallets; they are contactless cybersecurity ecosystems. Unlike Ledger, these devices are battery-less and cable-less, eliminating physical ports (USB/Bluetooth) as attack vectors.

Internationally Patented Security

Freemindtronic’s architecture is anchored by two fundamental international patents (WIPO) that solve the structural flaws found in traditional hardware wallets:

  • Segmented Key Authentication System (WO2018154258): Prevents the compromise of the whole seed or private key, even if the environment is attacked.
  • Access Control System (WO2017129887): Ensures that the HSM can only be triggered by the user’s physical intent via NFC, neutralizing remote software threats.

Unified Security: Hardware-Based Password Management

One of the most innovative features of the SeedNFC HSM is its integration of the EviPass NFC HSM technology. This addresses the “human factor” exploited in phishing scams.

  • Decentralized & Passwordless: Manage non-morphic passwords without ever storing them on a computer.
  • Physical Entropy: Immunity to keyloggers and screen recorders used in the Connect Kit attacks.
  • Contactless Convenience: Secure auto-fill by simply tapping your device.

Universal Access: Smartphone & Desktop Integration

On Android: Use native NFC for instant, battery-free hardware security.
On Desktop: Secure authentication directly in your browser via the Freemindtronic Extension.

Advanced “Air-Gap” Input: Keyboard Emulation

To bypass compromised clipboards, Fullsecure with Inputstick enables hardware-level data injection.

How it works: Your smartphone acts as a Bluetooth HID Keyboard, “typing” secrets directly into any device.

  • No Clipboard Exposure: Secrets never pass through the computer’s buffer.
  • Hardware Injection: Neutralizes software-based keyloggers relying on human keystroke capture.

Important clarification: transferring a private key is not a transaction. It is an off-chain transfer of ownership, granting full control over the associated assets.

Active Defense: Neutralizing BITB & Redirection Attacks

The SeedNFC HSM ecosystem, when paired with the free PassCypher HSM PGP version and the browser extension, provides a unique multi-layered shield against modern web threats:

    • Anti-BITB (Browser-In-The-Browser): The extension features a dedicated anti-iframe system. It detects and blocks malicious windows that simulate fake login screens—a common tactic used to steal Ledger credentials.
    • Automated Corruption Check: Integrated with Have I Been Pwned, the system automatically checks if your IDs or passwords have been compromised in historical leaks, ensuring you never use “vulnerable” credentials.
    • End-to-End Encrypted Auto-fill: Sensitive data is encrypted directly within the SeedNFC HSM on your Android device. It is only decrypted at the final millisecond of injection into the browser, ensuring that no plain-text data ever resides in the computer’s memory.

How to use: Open the Freemindtronic Android App (where SeedNFC is embedded), tap your HSM to your phone, and let the secure bridge handle the encrypted injection directly into your Chrome or Edge browser.

Best Practices to Protect Yourself

  • Never share your seed phrase or private keys — no support, update, delivery, or compliance process ever requires them.
  • Assume all inbound communication is hostile by default — (email, SMS, phone, social media). Always verify via official, manually accessed channels.
  • Strictly separate identity from asset ownership — use a dedicated email, avoid real-name linkage, and minimize purchase metadata exposure.
  • Avoid blind signing whenever possible — never sign transactions or approvals you cannot fully interpret and verify.
  • Prefer sovereign, hardware-only cold storage — (e.g., patented NFC HSM architectures) that do not rely on vendor servers, firmware updates, or e-commerce ecosystems.
  • Keep secrets out of connected environments — avoid clipboards, cloud sync, screenshots, password files, and shared devices.
  • Use hardware-enforced authentication and password management — to neutralize phishing, BITB, and credential reuse.
  • Plan for irreversible scenarios — define secure procedures for backup, migration, inheritance, and off-chain ownership transfer.
  • Accept operational responsibility — sovereignty implies discipline, physical control, and acceptance that some actions cannot be undone.

Securing the Future: From Vulnerability to Digital Sovereignty

Since 2017, the trajectory of Ledger Security Breaches has served as a critical case study for the entire crypto ecosystem. While Ledger remains a pioneer in hardware security, the recurring incidents—ranging from early physical exploits to the massive 2026 Global‑e data leak—demonstrate that a “secure device” is no longer enough. The threat has shifted from the chip itself to the systemic supply chain and the exposure of relational data.

The January 2026 incident confirms a persistent reality: even when private keys remain shielded, the leak of customer metadata (names, emails, and order history) creates a permanent risk of targeted phishing, doxxing, and social engineering. This highlights the inherent danger of centralized e‑commerce databases and the fragility of relying on third‑party partners for a product whose core promise is absolute security.

The Sovereign Alternative: Security by Design

To break this cycle of dependency, the paradigm must shift toward decentralized hardware security. This is where patented technologies developed by Freemindtronic in Andorra provide a structural response:

  • Physical Intent & Access Control (WO2017129887): Eliminates the remote attack surface by requiring a physical, contactless validation that cannot be spoofed by malicious software updates.
  • Segmented Key Authentication (WO2018154258): Protects against systemic breaches (like the Connect Kit attack) by ensuring that secrets are never centralized or fully exposed, even in a compromised environment.

This model does not promise convenience. It requires strict operational discipline, physical control, and acceptance of irreversibility.

For Ledger users, vigilance remains the primary line of defense. Respecting strict digital hygiene—verifying every communication via the official Ledger help center and using dedicated, non‑identifiable contact info for purchases—is essential. However, for those seeking to eliminate the “third‑party risk” entirely, transitioning to battery‑less, contactless, and patented NFC HSM solutions represents the next step in achieving true digital sovereignty.

As the crypto landscape evolves through 2026 and beyond, the lesson is clear: Don’t just trust the brand—trust the architecture.

Technical Reference: The EviCore and SeedNFC architectures are based on WO2017129887 and WO2018154258 patents. Developed by Freemindtronic Andorra for absolute digital sovereignty.

TETRA Security Vulnerabilities by Jacques Gascuel: This article will be updated with any new information on the topic.

TETRA Security Vulnerabilities

Tetra is a radio communication standard used by critical sectors worldwide. But it has five security flaws that could expose its encryption and authentication. How can you protect your Tetra system from hackers? Read this article TETRA Security Vulnerabilities to find out the best practices and tips.

TETRA Security Vulnerabilities: How to Protect Critical Infrastructures from Cyberattacks

TETRA (Terrestrial Trunked Radio) is a radio technology that is used worldwide for critical communications and data, especially in the sectors of security, energy, transport and defense. But this technology, which has been kept secret for more than 25 years, hides serious security vulnerabilities, including a backdoor that could allow devastating cyberattacks.

What is TETRA?

TETRA is a European radio standard that was developed in the 1990s to meet the needs of professional mobile services, such as police, firefighters, emergency services, military, prison staff, etc. TETRA allows to transmit data and voice encrypted on frequencies ranging from 380 to 470 MHz, with a range of several kilometers.

TETRA is used by more than 2000 networks in more than 150 countries, according to the TETRA and Critical Communications Association (TCCA), which brings together the manufacturers, operators and users of this technology. Among the main manufacturers of TETRA radios, we find Motorola Solutions, Hytera, Airbus, Sepura and Rohill.

TETRA offers several advantages over other radio technologies, such as:

  • better sound quality
  • greater transmission capacity
  • greater security thanks to encryption
  • greater flexibility thanks to the possibility of creating communication groups
  • greater interoperability thanks to the compatibility of equipment

What are the vulnerabilities of TETRA?

Despite its strengths, TETRA also has weaknesses, which have been revealed by a group of Dutch researchers from Radboud University Nijmegen. These researchers conducted a thorough analysis of the TETRA standard and its encryption algorithms, which were until then kept secret by the manufacturers and authorities.

The researchers discovered two types of major vulnerabilities in TETRA:

  • A backdoor in the encryption algorithm TEA1, which is used in radios sold for sensitive equipment, such as pipelines, railways, power grid, public transport or freight trains. This backdoor allows an attacker to decrypt the communications and data transmitted by these radios, and possibly to modify or block them. The backdoor exists since the creation of the algorithm TEA1, in 1998, and cannot be corrected by a simple software update. The researchers managed to extract the secret key of the backdoor by analyzing the binary code of the radios.
  • A weakness in the encryption algorithm TEA2, which is used in radios intended for professional mobile services, such as police, firefighters, emergency services, military or prison staff. This weakness allows an attacker to reduce the number of possible keys to test to decrypt the communications and data transmitted by these radios. The researchers estimated that it would take about 10 minutes to find the right key with a standard computer. This weakness was corrected by the manufacturers in 2016, but the radios that have not been updated remain vulnerable.

To find the backdoor in the TEA1 algorithm, the researchers used a technique called “differential analysis”, which consists of comparing the outputs of the algorithm for slightly different inputs. By observing the differences, they were able to identify a part of the code that was not normally used, but that was activated by a special condition. This condition was the presence of a secret key of 64 bits, which was hidden in the binary code of the radios. By analyzing the code, they were able to extract the secret key and test it on encrypted communications with the TEA1 algorithm. They were thus able to confirm that the secret key allowed to decrypt the communications without knowing the normal key of 80 bits. The researchers published their official report and the source code of the TETRA encryption algorithms on their website.

What are the risks for critical infrastructures?

The vulnerabilities identified in TETRA represent a danger for the critical infrastructures that use this technology, because they could be exploited by cybercriminals, terrorists or spies to disrupt or damage these infrastructures.

For example, an attacker could:

  • listen to the communications and confidential data of the security or defense services
  • impersonate an operator or a manager to give false instructions or orders
  • modify or erase data or commands that control vital equipment, such as valves, switches, signals or brakes
  • cause failures, accidents, fires or explosions

These scenarios could have dramatic consequences on the security, health, economy or environment of the countries concerned.

How to protect yourself from cyberattacks on TETRA?

The users of TETRA must be aware of the vulnerabilities of this technology and take measures to protect themselves from potential cyberattacks. Among the recommendations of the researchers, we can mention:

  • check if the radios used are affected by the vulnerabilities and ask the manufacturers for correction solutions
  • avoid using the algorithm TEA1, which contains the backdoor, and prefer safer algorithms, such as TEA3 or TEA4
  • use encryption keys that are long and complex enough, and change them regularly
  • set up verification and authentication procedures for communications and data
  • monitor the radio traffic and detect anomalies or intrusion attempts
  • raise awareness and train staff on cybersecurity and good practices

TETRA digital mode: how to transfer data via TETRA

TETRA (Terrestrial Trunked Radio) is a digital and secure radio communication standard used by emergency services, law enforcement, public transport and industries. TETRA uses a π/4-DQPSK phase modulation and a TDMA time division multiplexing to transmit voice and data on a bandwidth of 25 KHz per transmission channel. Each channel is divided into four timeslots, one of which is reserved for signaling in trunked mode (TMO).

TETRA allows file transfer via radio in two ways: by the packet data service (PDS) or by the circuit data service (CDS).

The PDS uses the IP protocol to transmit data packets on one or more timeslots. It offers a maximum throughput of 28.8 kbit/s per timeslot, or 86.4 kbit/s for three timeslots. The PDS can be used to send small files, such as images, text messages or forms.

The CDS uses the LAPD protocol to transmit data by circuit on a dedicated timeslot. It offers a constant throughput of 4.8 kbit/s per timeslot, or 19.2 kbit/s for four timeslots. The CDS can be used to send large files, such as documents, videos or maps.

The choice of the data service depends on the type of file, the size of the file, the quality of the radio link, the cost and the availability of radio resources. The PDS offers more flexibility and performance, but it requires a good signal quality and it can be more expensive in terms of battery consumption and spectrum occupation. The CDS offers more reliability and simplicity, but it requires a prior allocation of a timeslot and it can be slower and less efficient.

Securing TETRA file transfers with Freemindtronic’s EviCypher technology

However, both data services are subject to the TETRA security vulnerabilities that we have discussed in the previous sections. These vulnerabilities could allow an attacker to intercept, modify or corrupt the files transferred via TETRA, or to prevent their transmission altogether. Therefore, the users of TETRA must ensure the integrity and the confidentiality of the files they send or receive, by using encryption, verification and authentication methods. Freemindtronic’s EviCypher technology can be a valuable solution for encrypting data with post-quantum AES-256 from an NFC HSM with your own randomly generated keys before transferring them via TETRA. This way, even if an attacker corrupts the data transmitted by TETRA, they will not be able to decrypt the data encrypted by a product embedding

How to secure file transfers via TETRA with Freemindtronic’s EviCypher technology

La technologie EviCypher de Freemindtronic peut être une solution précieuse pour chiffrer les données avec AES-256 post-quantique à partir d’un HSM NFC avec vos propres clés générées aléatoirement avant de les transférer via TETRA. Ainsi, même si un attaquant corrompt les données transmises par TETRA, il ne pourra pas décrypter les données cryptées par un produit embarquant la technologie EviCypher NFC HSM technology, such as DataShielder NFC HSM or DataSielder Defense NFC HSM. These products are portable and autonomous devices that allow you to secure the access to computer systems, applications or online services, using the NFC as a means of authentication and encryption.

The management of encryption keys for TETRA

To use encryption on the TETRA network, you need an encryption key, which is a secret code of 80 bits, or 10 bytes. This key must be shared between the radios that want to communicate securely, and must be protected against theft, loss or compromise.

There are several methods to save and enter encryption keys for TETRA, depending on the type of radio and the level of security required. Here are some examples:

  • The manual method: it consists of entering the encryption key using the keyboard of the radio, by typing the 10 bytes in hexadecimal form. This method is simple, but impractical and unsafe, because it requires to know the key by heart or to write it down on a support, which increases the risk of disclosure or error. For example, a 80-bit key could be 3A4F9C7B12E8D6F0.
  • The automatic method: it consists of using an external device, such as a computer or a smart card, which generates and transfers the encryption key to the radio by a cable or a wireless link. This method is faster and more reliable, but it requires to have a compatible and secure device, and to connect it to the radio at each key change.
  • The EviPass method: it consists of using the EviPass NFC HSM technology which allows to generate, store and manage keys and secrets in a secure and independent NFC HSM device. This method is the most innovative and secure, because it allows to create keys higher than 80 bits randomly in hexadecimal base 16, 58, 64 or 85, to store them in a physical device protected by an access code and a robust AES-256 post-quantum encryption algorithm, and to transfer them by various contactless means, via a computer. This method does not require to know or write down the key, which reduces the risk of disclosure or error. For example, a 10-byte key of 80 bits could be 3F 8A 6B 4C 9D 1E 7F 2A 5B 0C.

The EviPass NFC HSM technology of Freemindtronic allows to create secure gateways between the NFC devices and the computer systems, using advanced encryption protocols, such as AES, RSA or ECC. The EviPass NFC HSM technology is embedded in the PassCyber NFC HSM product, which is a portable and autonomous device that allows to secure the access to computer systems, applications or online or offligne services, using the NFC as a means of authentication.

Conclusion

TETRA is a radio technology that was designed to offer secure and reliable communication to professional mobile services and critical infrastructures. But this technology, which has been kept secret for decades, presents vulnerabilities that could be exploited by cyberattackers to compromise these communications and infrastructures. The users of TETRA must be vigilant and take measures to protect themselves from these threats, by updating their equipment, choosing robust encryption algorithms, using strong keys, verifying and authenticating data and monitoring radio traffic. The EviPass NFC HSM technology of Freemindtronic can be an effective solution to strengthen the security of keys and secrets used for verification and authentication, by storing them in a secure and independent NFC device. The researchers who revealed the vulnerabilities of TETRA hope that their work will contribute to improve the security of communications in critical domains.
