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:

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.

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).

5Ghoul: How Contactless Encryption Can Secure Your 5G Communications from Modem Attacks

5Ghoul is a set of 5G NR vulnerabilities that affect Qualcomm and MediaTek modems. These flaws allow to launch denial-of-service attacks or degrade the quality of the 5G network.

What is 5Ghoul?

5Ghoul is a set of 14 5G NR (New Radio) vulnerabilities, the protocol that governs the communication between 5G devices and base stations (gNB). Among these vulnerabilities, 10 are public and 4 are still confidential. They were discovered by researchers from the Singapore University of Technology and DesignSingapore University of Technology and Design.

The 5Ghoul vulnerabilities exploit implementation errors in Qualcomm and MediaTek modems, which do not comply with the specifications of the 5G NR protocol. They allow an attacker to create a fake base station, which pretends to be a legitimate one, and send malicious messages to 5G devices that connect to it. These messages can cause errors, crashes or infinite loops in the modems, resulting in denial-of-service attacks or degradations of the quality of the 5G network.

Which devices are affected by 5Ghoul?

The researchers tested the 5Ghoul vulnerabilities on 714 models of 5G smartphones from 24 different brands, including Lenovo, Google, TCL, Microsoft, etc. They also tested routers and modems 5G from various manufacturers. They found that the 5Ghoul vulnerabilities affect all 5G devices equipped with Qualcomm and MediaTek modems, which account for more than 90% of the market.

What are the impacts of 5Ghoul?

The impacts of 5Ghoul depend on the vulnerability exploited and the type of device targeted. The researchers classified the 5Ghoul vulnerabilities into three categories, according to their severity:

Level 1 vulnerabilities

Level 1 vulnerabilities are the most severe. They allow to render 5G devices completely unusable, by locking them in a state where they can neither connect nor disconnect from the 5G network. These vulnerabilities require a manual reboot of the devices to be resolved. Among the level 1 vulnerabilities, there is for example the CVE-2023-33043, which causes a crash of the Qualcomm X55/X60 modem by sending an invalid MAC/RLC message.

Level 2 vulnerabilities

Level 2 vulnerabilities are less critical, but still harmful. They allow to degrade the quality of the 5G network, by reducing the throughput, latency or stability of the connection. These vulnerabilities can be resolved by reconnecting to the 5G network. Among the level 2 vulnerabilities, there is for example the CVE-2023-33044, which causes packet loss on the MediaTek T750 modem by sending an invalid RRC message.

Level 3 vulnerabilities

Level 3 vulnerabilities are the least dangerous. They allow to disrupt the normal functioning of 5G devices, by displaying error messages, modifying settings or triggering alerts. These vulnerabilities have no impact on the quality of the 5G network. Among the level 3 vulnerabilities, there is for example the CVE-2023-33045, which causes an error message on the Qualcomm X55/X60 modem by sending an invalid RRC message.

How to protect yourself from 5Ghoul?

The researchers informed the manufacturers of Qualcomm and MediaTek modems of the 5Ghoul vulnerabilities, as well as the 5G network operators and the 5G device manufacturers. They also published a demonstration kit of the 5Ghoul vulnerabilities on GitHub, to raise awareness among the public and the scientific community of the risks of 5G NR.

To protect yourself from 5Ghoul, 5G device users must update their modems with the latest security patches, as soon as they are available. They must also avoid connecting to unreliable or unknown 5G networks, which could be fake base stations. In case of doubt, they can disable 5G and use 4G or Wi-Fi.

How 5Ghoul compares to other 5G attacks?

5Ghoul is not the first security flaw that affects 5G. Other 5G attacks have been discovered in the past, exploiting weaknesses in the protocol or in the equipment. Here are some examples of 5G attacks and their differences with 5Ghoul:

ReVoLTE

ReVoLTE is an attack that allows to listen to voice calls 4G and 5G by exploiting a vulnerability in the encryption of data. This vulnerability is due to the fact that some base stations reuse the same encryption key for multiple communication sessions, which allows an attacker to decrypt the content of the calls by capturing the radio signals.

It is different from 5Ghoul because it does not target the 5G modem, but the encryption of data. ReVoLTE also requires that the attacker be close to the victim and have specialized equipment to intercept the radio signals. ReVoLTE does not cause denial of service or degradation of the network, but it compromises the confidentiality of communications.

ToRPEDO

ToRPEDO is an attack that allows to locate, track or harass mobile phone users 4G and 5G by exploiting a vulnerability in the paging protocol. This protocol is used to notify mobile devices of incoming calls or messages. By sending repeated messages to a phone number, an attacker can trigger paging messages on the network, and thus determine the position or identity of the target device.

It is different from 5Ghoul because it does not target the 5G modem, but the paging protocol. ToRPEDO also requires that the attacker knows the phone number of the victim and has access to the mobile network. ToRPEDO does not cause denial of service or degradation of the network, but it compromises the privacy of users.

IMP4GT

IMP4GT is an attack that allows to degrade the quality of the 5G network by exploiting a vulnerability in the security protocol. This protocol is used to authenticate and encrypt the communications between 5G devices and base stations. By modifying the messages exchanged between the two parties, an attacker can mislead the network and the device on the level of security required, and thus reduce the throughput or latency of the connection.

It is different from 5Ghoul because it does not target the 5G modem, but the security protocol. IMP4GT also requires that the attacker be close to the base station and have equipment capable of modifying the messages. IMP4GT does not cause denial of service or crash of the modem, but it degrades the quality of the network.

SS7

SS7 is a set of signaling protocols used by mobile operators to establish and manage calls and messages between different networks. SS7 has existed since the 1970s and has not evolved much since, making it vulnerable to hacking attacks. By exploiting the flaws of SS7, an attacker can intercept SMS and voice calls, locate and track users, bypass two-factor authentication, or subscribe subscribers to paid services without their consent.

It is different from 5Ghoul because it does not target the 5G modem, but the signaling protocol. SS7 affects all types of mobile networks, including 5G, because it still uses SS7 for some functions, such as mobility management or compatibility with 2G and 3G networks. SS7 requires that the attacker has access to the signaling network, which is not easy to obtain, but not impossible. SS7 does not cause denial of service or crash of the modem, but it compromises the confidentiality and integrity of communications.

How and why to encrypt SMS, MMS and RCS without contact?

Contactless encryption is a method of protecting mobile communications that uses NFC (Near Field Communication) technology to establish a secure connection between two devices. NFC is a wireless communication protocol that allows to exchange data by bringing two compatible devices within a few centimeters of each other.

Contactless encryption relies on the use of an external device called NFC HSM (Hardware Security Module), which is a hardware security module that stores and manages encryption keys. The NFC HSM comes in the form of a card, a keychain or a bracelet, that the user must bring close to his phone to activate the encryption. The NFC HSM communicates with the phone via NFC and transmits the encryption key needed to secure the messages.

The technologies EviCore NFC HSM and EviCypher NFC HSM are examples of contactless encryption solutions developed by the Andorran company Freemindtronic. EviCore NFC HSM is a hardware security module that allows to encrypt SMS, MMS and RCS (Rich Communication Services) end-to-end, meaning that only the recipients can read the messages. EviCypher NFC HSM is a hardware security module that allows to encrypt multimedia files (photos, videos, audio, etc.) and share them via SMS, MMS or RCS.

Contactless encryption has several advantages over conventional encryption of mobile communications:

It offers a higher level of security, because the encryption key is not stored on the phone, but on the NFC HSM, which is more difficult to hack or steal.

It is compatible with all types of mobile networks, including 5G, because it does not depend on the communication protocol used, but on NFC.

It is easy to use, because it is enough to bring the NFC HSM close to the phone to activate the encryption, without having to install a specific application or create an account.

It is transparent, because it does not change the appearance or functioning of the messages, which remain accessible from the native application of the phone.

Statistics on 5Ghoul

How widespread are 5Ghouls? What are the trends and impacts of these flaws? Some statistics on 5Ghoul, based on sources and data that are a priori reliable.

5Ghoul: a threat to 5G devices

5Ghoul is a set of 5G NR vulnerabilities that affect Qualcomm and MediaTek modems, which are used by most 5G devices on the market. According to the researchers who discovered 5Ghoul, these vulnerabilities can cause denial-of-service attacks or network degradations.

  • How many 5G devices are affected by 5Ghoul? According to a report by Counterpoint Research, Qualcomm and MediaTek accounted for 79% of the global smartphone chipset market in Q3 2020. Qualcomm had a 39% share, while MediaTek had a 40% share. Assuming that all Qualcomm and MediaTek chipsets are vulnerable to 5Ghoul, this means that nearly 8 out of 10 smartphones are potentially at risk.
  • How many 5G NR vulnerabilities are known? According to the CVE (Common Vulnerabilities and Exposures) database. There are 16 CVE entries related to 5G NR as of April 2021. Four of them are ZeroDay vulnerabilities that have not been publicly disclosed nor fixed by the manufacturers. These vulnerabilities are classified as level 1 or 2, meaning that they can cause denial-of-service attacks or network degradations.
  • How many 5G attacks have been reported? According to the SANS Internet Storm Center, there have been no reports of 5Ghoul attacks in the wild as of April 2021. However, this does not mean that 5Ghoul is not exploited by malicious actors. The researchers who discovered 5Ghoul have developed a proof-of-concept tool called 5Ghoul-Scanner, which can detect and exploit 5Ghoul vulnerabilities. They have also released a video demonstration of 5Ghoul attacks.

Conclusion

5Ghoul is a security flaw that affects 5G modems from Qualcomm and MediaTek, which are used by most 5G devices on the market. 5Ghoul allows an attacker to disrupt the functioning of smartphones, routers and modems 5G, or even make them unusable. 5Ghoul stands out from other 5G attacks known, such as ReVoLTE, ToRPEDO, IMP4GT or SS7, by the fact that it targets the 5G modem, that it does not require secret information or specialized equipment, and that it causes denial-of-service attacks or degradations of the network. To protect yourself from 5Ghoul, 5G device users must update their modems with the latest security patches, and avoid connecting to unreliable or unknown 5G networks.

Ledger Security Breaches from 2017 to 2023: How to Protect Your Cryptocurrencies from Hackers

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 victim of several security breaches, which have exposed the personal data and private keys of its users. 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.

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.

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. For example, other hardware wallets, such as Trezor or Keepser, offer similar features and security levels as Ledger, but they may have different designs, interfaces, or prices. 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, 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. Another option is to use a cold wallet, such as SeedNFC HSM, which is a patented HSM that uses NFC technology to store and manage your cryptocurrencies offline, 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.

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.
  • 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

Technological alternatives are already available, such as EviCore NFC HSM, EviCore HSM OpenPGP, EviCore NFC HSM Browser Extension and the NFC HSM devices that work without contact, developed and manufactured by Freemindtronic in Andorra. These are new cyber security and safety technologies that use HSMs with or without NFC. They offer a wide range of security features to manage your cryptocurrencies and other digital assets. These technologies also offer the hardware management of complex and complicated passwords by EviPass NFC HSM, OTP (2FA) keys by EviOTP NFC HSM, Seed Phrases by EviSeed NFC HSM, and the creation of multiple cryptocurrency wallets on the same device.

Conclusion

Ledger, the French leader in cryptocurrency security, has faced several security breaches since 2017. As a result of these breaches, hackers could steal the private keys and funds of Ledger users. In response to these threats, Ledger reacted by publishing security updates, informing its users, and strengthening its protection measures. However, Ledger users must be vigilant and follow the recommendations of Ledger to protect themselves from these attacks. Despite these challenges, Ledger remains a reliable and secure device to manage cryptocurrencies, as long as the best practices of digital hygiene are respected. If you want to learn more about Ledger and its products, you can visit their official website or read their blog. Additionally, you can also check their security reports and their help center for more information.

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.

How to Protect Your Gmail Account from FormBook Malware

Introduction

Imagine that you receive an email from your bank, asking you to confirm your identity by clicking on a link. You open the link, and you find yourself on a page that looks like your bank’s website, but it is actually a fake. You enter your credentials, and you think you are done. But in reality, you have just given access to your bank account to hackers, who will use it to steal your money, or worse. This is what FormBook can do, a malware that can steal your sensitive data, and that Google cannot stop. In this article, we will explain what FormBook is, how it works, and how to protect yourself from this malware.

What is FormBook and why is it a threat?

FormBook is a malware that can record your keystrokes, take screenshots, and steal your passwords, cookies, and clipboard data. It can also download and execute other malicious files on your device.

FormBook is distributed through phishing emails that contain malicious attachments. These attachments are usually disguised as invoices, receipts, or shipping confirmations. When you open them, they ask you to enable macros or content. If you do, the malware will be installed on your device.

FormBook can target any web browser, but it has a special feature for Chrome. It can inject a fake Gmail login page into your browser, and trick you into entering your credentials. The malware will then send your Gmail username and password to a remote server controlled by the hackers.

FormBook is a threat because it can compromise your Gmail account and access your personal and professional information. It can also use your Gmail account to send spam or phishing emails to your contacts, or to access other online services that are linked to your Gmail account, such as Google Drive, Google Photos, or Google Pay.

How to protect yourself from FormBook?

Google has not yet found a way to detect and block FormBook. Therefore, you need to be extra careful when you use Gmail and other online services. Here are some tips to protect yourself from FormBook and other malware:

  • Do not open or download attachments from unknown or suspicious senders. If you are not sure about the legitimacy of an email, contact the sender directly or check the official website of the company or organization.
  • Do not enable macros or content in any document unless you trust the source. Macros are small programs that can run malicious code on your device.
  • Use a strong and unique password for your Gmail account and other online accounts. Do not reuse the same password for different services. Change your password regularly and use a password manager to store and generate your passwords.
  • Enable two-factor authentication (2FA) for your Gmail account and other online accounts. 2FA adds an extra layer of security by requiring a code or a device confirmation in addition to your password.
  • Use a reputable antivirus software and keep it updated. Antivirus software can scan your device for malware and remove it. You can also use a browser extension that can block malicious websites and pop-ups.

Recent statistics on FormBook

FormBook is a malware that was first discovered in 2016, but it remains very active and dangerous. According to the Check Point report on cybersecurity in 2022, FormBook was the third most widespread malware in 2021, attacking 5% of enterprise networks. It was also the most prolific infostealer malware, accounting for 16% of attacks worldwide.

FormBook spreads mainly through phishing emails that contain malicious attachments. These attachments are often RAR self-extracting archives, which are compressed files that can run malicious code when opened. The RAR files contain a legitimate document, such as a PDF or a Word file, and a hidden executable file, which is the FormBook malware. When the user opens the RAR file, the document is displayed, but the malware is also installed in the background.

FormBook can also spread through other methods, such as drive-by downloads, malicious links, or removable media. The malware can infect any Windows device, from Windows XP to Windows 10. The malware can also evade detection and removal by using various techniques, such as encryption, obfuscation, or anti-analysis.

Here are some recent statistics on FormBook, based on the data from Check Point and ANY.RUN:

  • FormBook was the most popular malware in August 2021, affecting 4.5% of organizations worldwide, followed by Trickbot and Agent Tesla, affecting respectively 4% and 3% of organizations worldwide.
  • FormBook was the fourth most common malware in 2020, according to the ranking of malware families by ANY.RUN. It accounted for 8% of the samples analyzed by the online sandboxing service.
  • FormBook was used in many phishing campaigns targeting various industries, such as defense, aerospace, health, education, finance, retail, etc. It was also used to attack Ukrainian targets during the war between Russia and Ukraine in 2022.
  • FormBook has a successor called XLoader, which appeared in 2020 and which is able to infect macOS users. XLoader is sold on the dark web for $59 for a Windows license and $49 for a macOS license.

Danger level of FormBook compared to other malware

FormBook is a very dangerous malware, because it can steal sensitive information, such as credentials, passwords, credit card numbers, 2FA codes, etc. It can also download and execute other malware, such as ransomware, banking trojans, spyware, etc. It can also remotely control the infected device and perform various malicious actions, such as deleting browser cookies, taking screenshots, restarting or shutting down the system, etc.

FormBook is also hard to detect and remove, because it uses advanced evasion techniques, such as code injection, string obfuscation, data encryption, anti-analysis, etc. It also changes frequently its name, path, and file extension, and uses random Windows registry keys to maintain its persistence.

To compare the danger level of FormBook with other known malware in its category, we can use the following criteria:

  • The number of organizations affected worldwide
  • The type and amount of information stolen
  • The ability to download and execute other malware
  • The ability to remotely control the infected device
  • The evasion techniques used
  • The ease of detection and removal

Here is a table that compares FormBook with other popular infostealer malware, such as Trickbot, Agent Tesla, LokiBot, and Raccoon:

Malware Number of organizations affected Type and amount of information stolen Ability to download and execute other malware Ability to remotely control the infected device Evasion techniques used Ease of detection and removal
FormBook 4.5% in August 2021 Credentials, passwords, credit card numbers, 2FA codes, screenshots, keystrokes, etc. Yes Yes Code injection, string obfuscation, data encryption, anti-analysis, etc. Hard
Trickbot 4% in August 2021 Credentials, passwords, banking information, personal data, etc. Yes Yes Code injection, string obfuscation, data encryption, anti-analysis, etc. Hard
Agent Tesla 3% in August 2021 Credentials, passwords, banking information, personal data, screenshots, keystrokes, etc. No Yes String obfuscation, data encryption, anti-analysis, etc. Medium
LokiBot 1.5% in August 2021 Credentials, passwords, banking information, personal data, etc. No Yes String obfuscation, data encryption, anti-analysis, etc. Medium
Raccoon 0.8% in August 2021 Credentials, passwords, banking information, personal data, etc. No Yes String obfuscation, data encryption, anti-analysis, etc. Medium

From this table, we can see that FormBook is the most dangerous infostealer malware, because it affects the most organizations, steals the most types of information, and can download and execute other malware. It is also the hardest to detect and remove, because it uses more evasion techniques than the other malware.

Forms of attacks of FormBook

FormBook can be delivered through different forms of attacks, depending on the delivery mechanism chosen by the malicious actor. Here are some forms of attacks of FormBook:

  • Phishing: FormBook can be sent by email as a malicious attachment, such as a Word, Excel, PDF, or ZIP or RAR file. The email can have a misleading subject, such as an invoice, a receipt, a contract, a job offer, etc. When the user opens the attachment, the malware runs and infects the device.
  • Exploitation of vulnerabilities: FormBook can exploit vulnerabilities in popular software, such as Microsoft Office, Windows, Adobe Reader, etc. For example, FormBook used the vulnerability CVE-2017-8570 in Microsoft Office to run malicious code from a RTF file. FormBook also used the vulnerability CVE-2021-40444 in Microsoft MSHTML to run malicious code from a CAB file.
  • Drive-by downloads: FormBook can be downloaded without the user’s knowledge when they visit a compromised or malicious website. The website can use a script or an exploit kit to trigger the download and execution of the malware on the user’s device.
  • Removable media: FormBook can be copied to removable media, such as USB drives, external hard drives, memory cards, etc. When the user connects the removable media to their device, the malware runs automatically and infects the device.
  • Social media: FormBook can be spread by messages or posts on social media, such as Facebook, Twitter, Instagram, etc. These messages or posts can contain links or images that redirect to malicious websites or infected files. When the user clicks on the link or image, the malware is downloaded and executed on their device.

Brute Force: danger and protection 80% of cyberattacks are brute force attacks. This technique tests all combinations to find the password, key, URL or hash of a system. These attacks threaten the security of your data. How to protect yourself? What tools and practices to adopt? This article explains:

  • Brute force types and methods : they vary according to the hackers’ method, the intrusion level and the application domain.
  • Brute force on electronic components : physical or electrical techniques are used to target chips or boards.
  • Brute force on passwords, keys, URLs and hashes : software or network techniques are used to access websites, online accounts, encrypted files, etc.
  • Brute force on phone systems : code or key techniques are used to hack landlines, mobiles or VoIP services.
  • Protection from brute force on devices and domains : encryption, authentication, masking, verification or correction techniques can help you strengthen your security.
  • Resistance evaluation of products or services to brute force : a scoring model based on the attack type and severity can help you assess the risk.

Types and Methods of Brute-force Attacks

There are several types and methods of brute force attacks, depending on the hackers’ method, the level of intrusion, and the domain of application.

Hackers’ Method

Hackers can use different methods to perform brute force attacks, depending on the type of data they want to obtain or modify. Here are the most common ones:

  • Simple brute force attacks: hackers try to guess the password of a user without using software, based on personal information or common passwords. These attacks work against users who have weak and easy-to-guess passwords, such as “password”, “1234567890”, or “qwerty”.
  • Dictionary attacks: hackers use software that tries passwords from a predefined list of common words, such as those from a dictionary or a database. These attacks are faster than simple ones but less effective against complex and random passwords.
  • Hybrid brute force attacks: hackers combine the previous two methods by adding variations to the dictionary words, such as numbers, symbols, or capital letters. These attacks are more sophisticated and can crack more robust passwords but they take more time and resources.
  • Reverse brute force attacks: hackers target the username rather than the password, assuming that the password is easier to guess or obtain by other means. These attacks are useful to access accounts that use the same username on multiple sites or services.
  • Distributed brute force attacks: hackers use multiple computers or devices connected to the Internet to perform brute force attacks simultaneously on the same target. These attacks are more powerful and harder to detect because they distribute the load and avoid security measures such as attempt limits or IP blocks.
  • Non-invasive faster than brute force attacks: hackers exploit weaknesses in the design or implementation of a system to reduce the number of combinations to test to find a secret information. For example, they can use a technique called “side-channel cube attack” to break AES encryption in less than 10 minutes with a laptop.
  • Analogous attacks: hackers use methods similar to brute force attacks but that do not test all possible combinations. For example, they can use a technique called “binary search attack” to guess a PIN code in less than 20 tries by exploiting the system’s response (correct/incorrect).

Level of Intrusion

Brute force attacks can also be classified according to the level of intrusion they involve:

  • Invasive attacks: hackers access physically the system or device they want to hack, using for example a keyboard, a USB stick, or a cable. These attacks are more dangerous because they can bypass software or network protections but they require proximity with the target and a risk of being caught.
  • Non-invasive attacks: hackers do not need to access physically the system or device they want to hack; they do it remotely via Internet or wireless network. These attacks are more discreet and easier to perform but they can be blocked by firewalls, antivirus software or secure protocols.

Domain of Application

Hackers’ objectives and motivations determine the domains where they apply brute force attacks. Here are some examples:

  • The civil domain: Hackers use brute force attacks to access personal or professional accounts such as emails, social networks, online banks or cloud services. They can steal sensitive information, impersonate identities, extort money or harm the reputation of the victims.
  • The defense domain: Hackers compromise national or international security by targeting military, governmental or diplomatic systems with brute force attacks. They can spy, sabotage, destabilize or provoke conflicts between countries.
  • The ethical hacking domain: Hackers test the security of systems or devices with brute force attacks by putting themselves in the attackers’ shoes. They can identify and report flaws, improve protections or train users.
  • The research domain: Hackers advance science and technology by exploring the limits of systems or devices with brute force attacks. They can discover new possibilities, innovate or create new products.

Brute-force Attacks on Electronic Components

Brute force attacks are not limited to passwords or encryption keys. They can also target electronic components that store or process data such as chips or integrated circuit boards. These attacks aim to access encrypted or protected information that is in the hardware using physical or electrical techniques.

Invasive Attacks

Invasive attacks are attacks that require direct access to the hardware and that involve modifying or destroying it. These attacks are often used to reverse engineer or extract data from chips or smart cards. Here are some examples:

  • Decapsulation: this technique consists of removing the outer layer of protection of a chip to expose the silicon and the internal layers. This can be done mechanically or chemically for example with nitric acid.
  • Deprocessing: this technique consists of removing progressively the internal layers of a chip to access the transistors and the connections. This can be done with chemicals lasers or focused ion beams (FIB).
  • Removal of the passivation layer: this technique consists of removing the insulating layer that covers the surface of a chip to allow electrical contact with the bonding wires (the thin connections between the chip and the package).
  • Reverse engineering: this technique consists of analyzing the structure and the functioning of a chip or an integrated circuit board to extract the source code the algorithms or the vulnerabilities.
  • Micro-probing: this technique consists of using micro-probes (metal needles) to connect directly to the internal components of a chip or an integrated circuit board and interfere with the signals or extract data.
  • Instantaneous memory attack: this technique consists of freezing a chip or an integrated circuit board to preserve the data that is in the volatile memory (RAM) after cutting off the power supply. This technique allows bypassing the mechanisms of automatic erasure of sensitive data in case of intrusion attempt.
  • Securing pairing algorithms against physical attacks: this technique consists of protecting pairing algorithms which are used for identity-based encryption against physical attacks that aim to modify the behavior of the hardware. This technique uses mathematical methods to detect and correct errors induced by physical disturbances.

Non-invasive Attacks

Non-invasive attacks are attacks that do not need direct access to the hardware but that use auxiliary or hidden channels to obtain or modify data on chips or integrated circuit boards. These attacks exploit the physical characteristics of the hardware such as power consumption electromagnetic field acoustic noise or temperature. Here are some examples:

  • Side-channel attack: this technique consists of measuring a physical parameter related to the functioning of a chip or an integrated circuit board to deduce information about the operations it performs or the data it processes. For example it is possible to guess an encryption key by analyzing the power consumption of a chip while it encrypts or decrypts a message.
  • Fault injection attack: this technique consists of provoking an error in the functioning of a chip or an integrated circuit board by sending it an abnormal signal such as an electric pulse a light wave or ionizing radiation. This technique allows modifying the behavior of the hardware revealing hidden information or bypassing protections.
  • Software flaw attack: this technique consists of exploiting a vulnerability in the software that controls the functioning of a chip or an integrated circuit board to access or modify sensitive data. For example it is possible to take control of a router by using a flaw in its firmware (the internal software that controls the functioning of the hardware).
  • Hidden channel attack: this technique consists of exploiting information that is not directly related to the functioning of the targeted system such as noise temperature or time. For example it is possible to guess the PIN code of a phone by listening to the sound produced by the keys when entering it.

Brute-force Attacks on Passwords Encryption Keys Hidden URLs and Hashes

Passwords encryption keys hidden URLs and hashes are data that serve to protect access or confidentiality of information on Internet. Hackers can try to guess them using brute force attacks which consist in testing all possible combinations until they find the right one. These attacks can have serious consequences such as identity theft account hijacking message decryption or website hacking.

Attacks on Passwords

Passwords are secret codes that users enter to authenticate on a website or an online service. Hackers can try to guess them using brute force attacks simple dictionary hybrid reverse or distributed as we have seen previously. These attacks can allow hackers to access users’ accounts and steal their personal financial or

professional information. To protect themselves from these attacks, users should choose strong and unique passwords, use a password manager, enable two-factor authentication, and avoid phishing emails.

Attacks on Encryption Keys

Encryption keys are data that are used to encrypt or decrypt messages or files. They can be symmetric (the same key is used for encryption and decryption) or asymmetric (two different keys are used: a public key for encryption and a private key for decryption). Hackers can try to guess them using brute force attacks simple or distributed, by testing all possible combinations until they find the right one. These attacks can allow hackers to read or modify confidential messages or files.

To protect themselves from these attacks, users should choose long and random encryption keys, use secure encryption algorithms, do not disclose or store their encryption keys in insecure places, and use secure protocols to exchange their encryption keys with their correspondents, such as the Diffie-Hellman protocol or the SSL/TLS protocol.

Another type of brute force attack targets the data stored in the volatile memory of devices, such as computers and phones. Volatile memory is a type of memory that loses its content when the power supply is cut off. This makes it vulnerable to brute force attacks that aim to extract sensitive data from it, using physical or software techniques. In this section, we will explain what are brute force attacks on volatile memory, how they work, what are the risks and how to prevent them.

Tools for brute force attacks

There are many tools available for brute force attacks on different protocols or services. Some are used for malicious purposes, others for penetration testing or security audit. Here is a non-exhaustive list of tools for brute force attacks:

  • Hashcat: Hashcat claims to be the world’s fastest and most advanced password recovery tool based on CPU. It supports five unique modes of attack for over 300 optimized hashing algorithms.
  • Flipper Zero: a multifunctional device that allows you to perform brute force attacks on RFID, NFC, Bluetooth systems, etc.
  • Gobuster: a tool written in Go that allows you to perform brute force attacks on web directories, DNS subdomains, S3 buckets or virtual hosts.
  • BruteX: a shell-based tool that allows you to perform brute force attacks on different services such as FTP, SSH, Telnet, RDP, VNC, etc.
  • Dirsearch: a tool written in Python that allows you to perform brute force attacks on web directories and files.
  • Callow: a tool written in C# that allows you to perform brute force attacks on web forms.
  • SSB: a tool written in Perl that allows you to perform brute force attacks on SMTP servers.
  • THC-Hydra: a popular tool that allows you to perform brute force attacks on more than 50 protocols such as HTTP, HTTPS, FTP, SSH, Telnet, SMB, etc.
  • Burp Suite: a suite of tools that allows you to perform penetration testing on web applications, including brute force attacks on web forms or HTTP parameters.
  • Patator: a tool written in Python that allows you to perform modular brute force attacks on different services such as HTTP, FTP, SSH, SMTP, etc.
  • Pydictor: a tool written in Python that allows you to generate custom lists for brute force or dictionary attacks.
  • Ncrack: a tool that allows you to perform fast and flexible brute force attacks on different services such as RDP, SSH, Telnet, HTTP(S), POP3(S), etc.

Brute force attacks on volatile memory: a data security risk

Volatile memory is a type of memory that loses its content when the power supply is cut off. This is the case for the random access memory (RAM) of computers and phones, which temporarily stores data and programs that are running. Volatile memory has an advantage: it erases the traces of computer activity in case of power outage or system shutdown. But it also has a drawback: it can be targeted by brute force attacks aiming to recover the sensitive data it contains.

A brute force attack is a method that consists of testing all possible combinations of a password, an encryption key or an access code, until finding the right one. Brute force attacks can be performed using specialized software, which exploits the computing power of computers or networks of machines. Brute force attacks can take a lot of time, depending on the complexity and length of the password, key or code to guess.

Brute force attacks on volatile memory are attacks that aim to extract data stored in the RAM of a computer or a phone, using physical or software techniques. For example, it is possible to cool down the RAM with liquid nitrogen, which allows to preserve its content for a few minutes after the system shutdown. It is then possible to transfer the RAM to another device, and use a brute force software to decrypt the data it contains. It is also possible to use malicious software that infiltrates the system and accesses the RAM, bypassing software or hardware protections.

Brute force attacks on volatile memory pose a risk for data security, because they can allow hackers to access confidential information, such as passwords, encryption keys, personal or professional data, etc. These information can then be used to compromise other systems or services, or to extort the victims. To protect against these attacks, it is recommended to use passwords or keys that are long and complex enough, to encrypt data stored in the RAM, and to update software and hardware to benefit from the latest security measures.

To sum up, brute force attacks on volatile memory are a serious threat for data security, as they can allow hackers to access confidential information, such as passwords, encryption keys, personal or professional data, etc. These information can then be used to compromise other systems or services, or to extort the victims. To protect against these attacks, it is recommended to use passwords or keys that are long and complex enough, to encrypt data stored in the RAM, and to update software and hardware to benefit from the latest security measures.

Attacks on Hidden URLs

Hidden URLs are web addresses that are hidden or modified to avoid being easily accessible or identifiable. They can be used to protect the privacy or security of a website or an online service. For example, a website may use a hidden URL to prevent being indexed by search engines or targeted by hackers. Hackers can try to guess them using brute force attacks simple or distributed, by testing all possible combinations until they find the right one. These attacks can allow hackers to access hidden or forbidden websites, such as illegal, malicious, or sensitive websites.

To protect themselves from these attacks, users should choose long, complex, and random hidden URLs, do not use predictable or easy-to-guess hidden URLs, do not share or publish their hidden URLs with other people or on other websites, and use encryption or authentication techniques to enhance the security of their hidden URLs.

Attacks on Hashes

Hashes are data that result from applying a mathematical function to a message or a file. They are used to verify the integrity or authenticity of a message or a file, by comparing it to the original hash. They can also be used to store passwords securely, by transforming them into irreversible hashes. Hackers can try to guess them using brute force attacks simple, dictionary, or hybrid, by testing all possible combinations until they find the right hash. These attacks can allow hackers to falsify or reveal messages or files.

To protect themselves from these attacks, users should choose secure hashing functions that do not have collisions (two different messages that produce the same hash) or preimages (a message that produces a given hash), use salting (adding a random data to the message before hashing) or peppering (adding a secret data to the message before hashing) techniques to make hashes more resistant to brute force attacks, do not store or transmit their hashes in insecure places, and use secure protocols to exchange their hashes with their correspondents, such as the HMAC protocol or the SSL/TLS protocol.

Brute-force Attacks on Phone Systems

Phone systems are devices that allow communication by voice or text, such as landlines, mobile phones (smartphones), or VoIP services. Hackers can try to hack them using brute-force attacks that consist of guessing codes or keys. These attacks can allow hackers to access data or services of a phone system, such as contacts, messages, calls, payments, or subscriptions.

Attacks on PIN Codes

PIN codes are secret codes of four digits that are used to unlock a mobile phone or a SIM card. Hackers can try to guess them using brute force attacks simple or analogous by testing all possible combinations until they find the right one. These attacks can allow hackers to access data or services of the mobile phone or the SIM card.

To protect themselves from these attacks users should choose random and unpredictable PIN codes that do not contain numerical sequences easy to guess such as “0000” “1234” or “4321”. They should not write or share their PIN codes with other people. They should activate the function of automatic locking of the mobile phone or the SIM card after a certain number of unsuccessful attempts. They should activate the function of automatic reset of the mobile phone or the SIM card after a certain number of unsuccessful attempts.

Attacks on IMEI Codes

IMEI codes are unique codes of 15 digits that identify a mobile phone. They are used to block a mobile phone in case of theft or loss. Hackers can try to guess them using brute force attacks simple or distributed by testing all possible combinations until they find the right one. These attacks can allow hackers to unlock a stolen or lost mobile phone and use it for malicious purposes such as making fraudulent calls sending unwanted messages or accessing personal data of the owner.

To protect themselves from these attacks users should note their IMEI codes and keep them in a safe place. They should not disclose their IMEI codes to unknown or suspicious people. They should report the loss or theft of their mobile phone to their operator and request the blocking of their IMEI codes. They should use a service of location or remote locking of their mobile phone in case of loss or theft.

Evaluation of Products or Services Resistance to Brute-force Attacks

To evaluate the resistance of products or services to brute force attacks we can use a scoring model based on the type and severity of possible attacks. The scoring model can be as follows:

  • For each product or service we identify the possible types of brute force attacks that can target it such as passwords encryption keys hidden URLs hashes PIN codes or IMEI codes.
  • For each type of brute force attack we assign a score from 1 to 5 according to the severity of the attack. The score can be based on the following criteria: the complexity of the attack the time required to perform the attack the impact of the attack on the confidentiality integrity or availability of the data or service and the likelihood of the attack to succeed.
  • We calculate the average score for each product or service by adding up the scores for each type of brute force attack and dividing by the number of types. The lower the score the more resistant the product or service is to brute force attacks.

For example let’s consider two products: a web application and a smartphone. The possible types of brute force attacks and their scores are as follows:

Type of brute-force attack Web application Smartphone
Passwords 3 2
Encryption keys 4 3
Hidden URLs 2 N/A
Hashes 3 N/A
PIN codes N/A 2
IMEI codes N/A 4

The average score for the web application is (3 + 4 + 2 + 3) / 4 = 3. The average score for the smartphone is (2 + 3 + 2 + 4) / 4 = 2.75. Therefore, according to this scoring model, the smartphone is more resistant to brute force attacks than the web application.

Statistics on brute force attacks

Brute force attacks are common and effective methods used by hackers to access systems protected by passwords or encryption keys. According to the IBM Cost of a Data Breach 2022 report, stolen or compromised credentials are the leading cause of data breaches and cost an average of $4.35 million to businesses worldwide in 2021. Brute force attacks are also increasing with the health crisis, which has encouraged remote work and online services. According to Cloudflare, the number of brute force attacks on RDP and SSH protocols increased by 400% between March and April 2020.

The duration and difficulty of a brute force attack depend on the length and complexity of the password or key to guess. According to Cloudflare, a seven-character password would take, at a rate of 15 million keystrokes per second, 9 minutes to crack. An eight-character password would take 4 hours, a nine-character password would take 8 days, and a ten-character password would take 463 days. It is therefore essential to use passwords or keys that are long and random enough to resist brute force attacks.

Real Cases of Brute-force Attacks

Brute force attacks are not only theoretical methods, but also real threats that have affected various domains, such as finance, health, politics, etc. In this section, we will present some examples of brute force attacks that have taken place in recent years, and show their consequences and lessons.

Brute force attacks on financial institutions

Financial institutions are often targeted by brute force attacks, as they store sensitive data and money. For instance, in 2019, a group of hackers used brute force attacks to access the online banking systems of several banks in Eastern Europe and Central Asia. They stole over $100 million from more than 40,000 accounts. The hackers used a software called Cobalt Strike, which allowed them to remotely control the infected computers and launch brute force attacks on the banks’ servers. They also used a technique called “ATM cash-out”, which enabled them to withdraw money from ATMs without using cards.

This case shows the importance of using strong passwords and encryption keys for online banking systems, as well as updating the software and hardware to prevent malware infections. It also shows the need for monitoring and alerting mechanisms to detect and stop brute force attacks in real time.

Brute force attacks on health systems

Health systems are also vulnerable to brute force attacks, as they store personal and medical data that can be used for identity theft or blackmail. For example, in 2020, a hacker group called Maze used brute force attacks to breach the network of Fresenius, Europe’s largest private hospital operator. They encrypted the data and demanded a ransom for its release. The attack affected the hospital’s operations and patient care, as well as its subsidiaries that produce dialysis products and blood transfusion devices.

This case illustrates the impact of brute force attacks on human lives and health services. It also highlights the need for securing the network and data of health systems, as well as having backup and recovery plans in case of an attack.

Brute force attacks on political systems

Political systems are not immune to brute force attacks, as they can influence the outcome of elections or policies. For instance, in 2016, a hacker group called Fancy Bear used brute force attacks to access the email accounts of several members of the Democratic National Committee (DNC) in the United States. They leaked the emails to WikiLeaks, which published them online. The leaked emails revealed internal conflicts and controversies within the DNC, and damaged the reputation of Hillary Clinton, who was running for president against Donald Trump.

This case demonstrates the power of brute force attacks to manipulate public opinion and interfere with democratic processes. It also underscores the need for protecting the email accounts and communications of political actors, as well as educating the public about cyber threats and misinformation.

How to Prevent Brute-force Attacks

Brute force attacks are a serious threat to the security and privacy of users, systems, and devices. Therefore, it is important to take preventive measures to avoid or mitigate their impact. Here are some general tips to prevent brute force attacks:

  • Use strong and unique passwords, encryption keys, hidden URLs, hashes, PIN codes, and IMEI codes. They should be long, complex, and random, containing letters, numbers, and symbols. They should not be based on personal or predictable information, such as names, dates, or phone numbers.
  • Use secure encryption algorithms and hashing functions. They should not have known or exploitable flaws or weaknesses, such as collisions or preimages. They should have enough entropy (degree of unpredictability) to resist brute force attacks.
  • Use secure protocols and techniques to exchange and store data. They should provide encryption, authentication, verification, correction, masking, or salting features. They should use secure channels and devices to transmit and store data.
  • Use security software and hardware to protect systems and devices. They should include firewalls, antivirus software, sensors, or locks. They should detect and block brute force attacks or trigger self-destruction or data erasure mechanisms.
  • Use ethical hacking and research to test and improve the security of systems and devices. They should identify and report vulnerabilities, flaws, or weaknesses. They should provide solutions, innovations, or products to enhance the security of systems and devices.

Fingerprint Security

You will surely be amazed by our discoveries! These systems verify your identity on smartphones and other devices by using the unique patterns of your finger. But is their security level? In this study, we explore the weaknesses of these systems and how various actors, from cybercriminals to sovereign entities, can exploit them.

Fingerprint Biometrics: An In-Depth Exploration of Security Mechanisms and Vulnerabilities

It is a widely recognized biometric authentication system for identity verification. In this overview of fingerprint authentication systems, we will explore comprehensively to understand the complex world of fingerprint biometrics. Our goal is to provide a detailed exploration of these systems, their inner workings, vulnerabilities, and countermeasures.

Demystifying Fingerprint Systems: A Thorough Examination

Two fundamental components make up these systems: the fingerprint sensor and the comparison algorithm.:

The Fingerprint Sensor: Where Biometric Data Begins

These systems rely on an essential component: the fingerprint sensor. It captures the finger image and converts it into a digital format. Different types of sensors exist, each with their advantages and disadvantages:

  1. Optical sensors: They use light and a camera to create a high-resolution image.
  2. Capacitive sensors: They use an array of small capacitors to measure the differences in electrical charge between the ridges and valleys.
  3. Ultrasonic sensors: They use sound waves to create a three-dimensional image.
  4. Thermal sensors: They detect the heat emitted by the finger to generate an image.

The Comparison Algorithm: The Gatekeeper of Access

The comparison algorithm is a critical software component that analyzes the captured fingerprint image. Its role is vital:

  • Image Analysis: The algorithm scrutinizes the fingerprint image, extracting its unique features.
  • Template Comparison: It then compares these features to one or more stored templates, serving as reference fingerprints for authorized users.
  • Threshold Criteria: Access is granted if the algorithm determines a significant similarity between the captured image and a stored template, surpassing a predefined threshold. If not, the system considers the fingerprint invalid and denies access.

Fingerprint System Vulnerabilities and Attack Techniques

First, before evaluating attack techniques against fingerprinting systems, let’s explore different attack types, techniques, motivations, and strategies. In our thorough analysis of fingerprint system vulnerabilities, we must acknowledge numerous attack techniques employed by various actors. These techniques, driven by diverse motivations ranging from personal gain to malicious intent, illuminate the complexities of fingerprint system security. We’ve identified a total of twenty-five (25) distinct attack types, categorized into five groups in this study: “Electronic Devices for Biometric Attacks,” “Additional Fingerprint Attacks,” “Advanced Attacks,” “Attacks on Lock Patterns,” and “Attacks on Fingerprint Sensors.”

Attacks on Fingerprint Sensors

Fingerprint sensors, a common biometric authentication method, are vulnerable to several attack types and techniques update 23 february 2024:

ATTACK TYPE TECHNIQUE MOTIVATIONS STRATEGIES
Residual Fingerprint Attack Recovers the smartphone owner’s fingerprint left on surfaces, reproducing it. Identity theft, unauthorized access, or malicious purposes. Exploits traces of fingerprints on surfaces using materials like gelatin, silicone.
Code Injection Attack Injects malicious code to bypass fingerprint sensor security. Compromises device security for data theft or illicit activities. Exploits software vulnerabilities for unauthorized access to biometric data.
False Acceptance Attack The system accepts a fingerprint that doesn’t belong to the authorized user. Identity theft, unauthorized access, or malicious intentions. Can occur due to poor sensor quality, a high tolerance threshold, or similarity between different individuals’ fingerprints.
False Rejection Attack The system rejects a fingerprint that belongs to the authorized user. Identity theft, unauthorized access. Can occur due to poor sensor quality, a low tolerance threshold, environmental changes, or alterations to the user’s fingerprint.
Substitution Attack Tricks the system with an artificial fingerprint. Identity theft or unauthorized access. Can be done using materials like gelatin, silicone, latex, or wax.
Modification Attack Tricks the system with a modified fingerprint. Identity theft or to conceal the user’s identity. Can be done using techniques like gluing, cutting, scraping, or burning.
Impersonation Attack Tricks the system with another user’s fingerprint, either with their consent or by force. Identity theft using force, threats, bribery, or seduction. Uses the fingerprint of another user who has given consent or has been coerced into doing so.
Adversarial Generation Attack Tricks the system with images of fingerprints generated by an adversarial generative adversarial network (GAN). Bypasses liveness detection methods based on deep learning. Mimics the appearance of real fingerprints.
Acoustic Analysis Attack Tricks the system by listening to the sounds emitted by the fingerprint sensor during fingerprint capture. Can reconstruct the fingerprint image from acoustic signals. Use noise cancellation techniques, encrypt acoustic signals, or use liveness detection methods
Partial Print Attack Tricks the system with a partial fingerprint from the registered fingerprint. Increases the false acceptance rate by exploiting the similarity between partial prints of different users. Can use a portion of the registered fingerprint.
Privilege Escalation Attack Exploits vulnerabilities in the operating system or application to obtain higher privileges than those granted by fingerprint authentication Can access sensitive data, manipulate system files, perform unauthorized actions, or bypass security measures Use strong passwords, enforce multi-factor authentication, limit user privileges, patch system vulnerabilities, monitor user activities, and audit logs
Spoofing Attack Imitates a legitimate fingerprint or identity to deceive the system or the user Can gain access, steal information, spread malware, or impersonate someone. Use liveness detection methods, verify the authenticity, avoid trusting unknown sources, and report spoofing attempts
PrintListener: Side-channel Attack Utilizes acoustic signals from finger friction on touchscreens to replicate fingerprints Gain unauthorized access to devices and services protected by fingerprint authentication Implement noise interference, use advanced fingerprint sensors resistant to acoustic analysis, enable multifactor authentication, regularly update security protocols

For more information on new attack type “PrintListener” (a specific acoustic analysis attack), readers are encouraged to explore the detailed article at https://freemindtronic.com/printlistener-technology-fingerprints/.
These attacks expose vulnerabilities in fingerprint sensor technology and underline the need for robust security measures.

Attacks on Lock Patterns (For Lock Screen Authentication)

Lock patterns, often used on mobile devices for screen unlocking, are susceptible to various attack techniques:

ATTACK TYPE TECHNIQUE MOTIVATIONS STRATEGIES
Brute Force Attack Attempts all possible lock pattern combinations. Gains unauthorized device access. Systematically tests different pattern combinations.
Replica Fingerprint Attack Uses a 3D printer to create a replica fingerprint. Unauthorized access or identity theft. Produces a replica for sensor authentication.
Sensor Vulnerabilities Exploits sensor technology vulnerabilities. Compromises device security for malicious purposes. Identifies and exploits sensor technology weaknesses.
BrutePrint Attack Intercepts messages, emulating the fingerprint sensor. Gains unauthorized access, often with hardware components. Exploits communication protocol vulnerabilities.

These attacks target the vulnerabilities in lock pattern authentication and underscore the importance of strong security practices.

Advanced Attacks

Advanced attacks employ sophisticated techniques and technologies to compromise fingerprint systems:

ATTACK TYPE TECHNIQUE MOTIVATIONS STRATEGIES
Presentation Attack Presents manipulated images or counterfeit fingerprints. Espionage, identity theft, or malicious purposes. Crafts counterfeit fingerprints or images to deceive sensors.
Rapid Identification Attack Uses advanced algorithms to swiftly identify fingerprints. Corporate espionage, financial gain, or enhanced security. Quickly identifies fingerprints from extensive datasets.
Digital Footprint Attack Collects and analyzes the online data and activity of the target, using open source intelligence tools or data brokers Can obtain personal information, preferences, habits, or vulnerabilities of the target. Use privacy settings, delete unwanted data, avoid oversharing, and monitor online reputation

These advanced attacks leverage technology and data to compromise fingerprint-based security.

Network-Based Attacks

Network-based attacks are those that target the communication or data transmission between the device and the fingerprint authentication system. These attacks can compromise the integrity, confidentiality, or availability of the biometric data or the user session. In this section, we will discuss four types of network-based attacks: phishing, session hijacking, privilege escalation, and spyware.

ATTACK TYPE TECHNIQUE MOTIVATIONS STRATEGIES
Phishing Attack Technique: Phishing attacks involve sending fraudulent messages to victims, enticing them to click on a link or download an attachment. These malicious payloads may contain code designed to steal their fingerprints or redirect them to a fake website requesting authentication. Motivations: Phishing attacks are motivated by the desire to deceive and manipulate users into revealing their fingerprint data or login credentials. Strategies: Phishing attackers employ various tactics, such as crafting convincing emails, spoofing legitimate websites, and using social engineering to trick users.
Session Hijacking Attack Technique: Session hijacking attacks aim to intercept or impersonate an authenticated user’s session, exploiting communication protocol vulnerabilities or using spyware. Motivations: Session hijacking is typically carried out to gain unauthorized access to sensitive information or systems, often for financial gain or espionage. Strategies: Attackers employ packet sniffing, session token theft, or malware like spyware to compromise and take control of active user sessions.
Spyware Attack Technique: Spyware attacks infect the device with spyware to capture fingerprint data. Motivations: Spyware attacks are driven by the objective of illicitly obtaining biometric data for malicious purposes, such as identity theft or unauthorized access. Strategies: Attackers use spyware to secretly record and transmit fingerprint information, often through backdoors or covert channels, without the victim’s knowledge.
Predator Files Infects Android phones with a spyware application that can access their data, including fingerprint information. Sold to multiple governments for targeting political opponents, journalists, activists, and human rights defenders in over 50 countries. Use spyware detection and removal tools, update system software, avoid downloading untrusted applications, and scan devices regularly

As we can see from the table above, network-based attacks pose a serious threat to fingerprint authentication systems and users’ privacy and security. Therefore, it is essential to implement effective countermeasures and best practices to prevent or mitigate these attacks. In the next section, we will explore another category of attacks: physical attacks.

Electronic Devices for Biometric Attacks

Some electronic devices are designed to target and compromise fingerprint authentication systems. Here are some notable examples:

Device Description Usage STRATEGIES
Cellebrite UFED A portable device capable of extracting, decrypting, and analyzing data from mobile phones, including fingerprint data. Used by law enforcement agencies worldwide. Used by law enforcement agencies to access digital evidence on mobile phones. Applies substances to damage or obscure sensor surfaces.
GrayKey A black box device designed to unlock iPhones protected by passcodes or fingerprints using a “brute force” technique. Sold to law enforcement and government agencies for investigative purposes. Sold to law enforcement and government agencies for investigative purposes to unlock iPhones. Use strong passwords, enable encryption, disable USB access, and update system software.
Chemical Attacks Alters or erases fingerprints on sensors. Prevents identification or creates false identities. Use fingerprint enhancement techniques, verify the authenticity, and use liveness detection methods

These devices pose a high risk to biometric systems because they can allow malicious actors to access sensitive information or bypass security measures. They are moderate to high in ease of execution because they require physical access to the target devices and the use of costly or scarce devices. Their historical success is variable because it depends on the quality of the devices and the security of the biometric systems. They are currently relevant because they are used by various actors, such as government agencies, law enforcement, or hackers, to access biometric data stored on mobile phones or other devices. This comprehensive overview of attack types, techniques, motivations, and strategies is crucial for improving biometric authentication system security.

BrutePrint: A Novel Attack on Fingerprint Systems on Phones

Fingerprint systems on phones are not only vulnerable to spoofing or data breach attacks; they are also exposed to a novel attack called BrutePrint. This attack exploits two zero-day vulnerabilities in the smartphone fingerprint authentication (SFA) framework. BrutePrint allows attackers to bypass the attempt limit and liveness detection mechanisms of fingerprint systems on phones. It also enables them to perform unlimited brute force attacks until finding a matching fingerprint.

How BrutePrint Works

Fingerprint Systems Really Secure : BrutePrint

BrutePrint works by hijacking the fingerprint images captured by the sensor. It applies neural style transfer (NST) to generate valid brute-forcing inputs from arbitrary fingerprint images. BrutePrint also exploits two vulnerabilities in the SFA framework:

  • Cancel-After-Match-Fail (CAMF): this vulnerability allows attackers to cancel the authentication process after a failed attempt. It prevents the system from counting the failed attempts and locking the device.
  • Match-After-Lock (MAL): this vulnerability allows attackers to infer the authentication results even when the device is in “lock mode”. It guides the brute force attack.To perform a BrutePrint attack, attackers need physical access to the phone, a database of fingerprints, and a custom-made circuit board that costs about 15 dollars. The circuit board acts as a middleman between the sensor and the application. It intercepts and manipulates the fingerprint images.

How to Prevent BrutePrint

BrutePrint is a serious threat to phone users who rely on fingerprint systems to protect their devices and data. It shows that fingerprint systems on phones are not as secure as they seem. They need more robust protection mechanisms against brute force attacks. Some of the possible ways to prevent BrutePrint are:

  • Updating the phone’s software: this can help fix the vulnerabilities exploited by BrutePrint and improve the security of the SFA framework.
  • Using multifactor authentication: this can increase the level of security and reduce the risks of spoofing or brute force attacks. It combines fingerprint authentication with another factor, such as a password, a PIN code, a pattern lock screen ,or other trust criteria that allows patented segmented key authentication technology developed by Freemindtronic in Andorra .
  • Use of DataShielder HSM solutions: these are solutions developed by Freemindtronic in Andorra that allow you to create HSM (Hardware Security Module) on any device, without a server or database, to encrypt any type of data. DataShielder HSM solutions also include EviSign technology, which enables advanced electronic signing of documents. DataShielder HSM solutions are notably available in Defense versions, which offer a high level of protection for civil and/or military applications.

The type of attack by electronic devices for biometric systems is very dangerous because it can allow malicious actors to access sensitive information or bypass the protections of biometric systems. Its ease of execution is moderate to high, as it requires physical access to target devices and the use of expensive or difficult-to-obtain devices. Its historical success is variable because it depends on the quality of the devices used and the security measures implemented by the biometric systems. It is currently relevant because it is used by government agencies, law enforcement or hackers to access biometric data stored on mobile phones or other devices.

Statistical Insights into Fingerprint Systems

Fingerprint systems have found wide-ranging applications, from law enforcement and border control to banking, healthcare, and education. They are equally popular among consumers who use them to unlock devices or access online services. However, questions linger regarding their reliability and security. Let’s delve into some pertinent statistics:

According to Acuity Market Intelligence, 2018 saw more than 1.5 billion smartphones equipped with fingerprint sensors, constituting 60% of the global market.

The IAFIS Annual Report of 2020 revealed that more than 1.3 billion fingerprint records were stored in national and international databases in 2019.

According to the National Institute of Standards and Technology (NIST), the average false acceptance rate of fingerprint systems in 2018 was 0.08%, marking an 86% decrease compared to 2013.

These statistics shed light on the widespread adoption of fingerprint systems and their improved accuracy over time. Nevertheless, they also underline that these systems, while valuable, are not without their imperfections and can still be susceptible to errors or manipulation.

Real-World Cases of Fingerprint System Corruption: Phone Cases

Fingerprint system corruption can also affect phone users, who rely on fingerprint sensors to unlock their devices or access online services. However, these sensors are not foolproof and can be bypassed or exploited by skilled adversaries. These attacks can result in device theft, data breaches, or other security issues.

Here are some examples of fingerprint system corruption that involve phones:

  • German hacker Jan Krissler, alias Starbug, remarkably unlocked the smartphone of the German Defense Minister Ursula von der Leyen in 2014 using a high-resolution photo of her thumb taken during a press conference. He employed image processing software to enhance the photo’s quality and created a counterfeit fingerprint printed on paper.
  • A terrorist attack at the Istanbul airport killed 45 people and injured more than 200 in 2016. The investigators found that the three suicide bombers used fake fingerprints to enter Turkey and avoid security checks. They copied the fingerprints of other people from stolen or forged documents.
  • Researchers from Tencent Labs and Zhejiang University discovered in 2020 that they could bypass a fingerprint lock on Android smartphones using a brute force attack, that is when a large number of attempts are made to discover a password, code or any other form of security protection.
  • Experts from Cisco Talos created fake fingerprints capable of fooling the sensors of smartphones, tablets and laptops as well as smart locks in 2020, but it took them a lot of effort.
  • A case of identity theft was discovered in France in 2021, involving the use of fake fingerprints to obtain identity cards and driving licenses. The suspects used silicone molds to reproduce the fingerprints of real people, and then glued them on their fingers to fool the biometric sensors.
  • Researchers from the University of Buffalo developed a method in 2021 to create artificial fingerprints from images of fingers. These fingerprints can fool the sensors of smartphones, but also more advanced biometric systems, such as those used by police or airports.
  • A report by Kaspersky revealed in 2021 that banking apps on smartphones are vulnerable to attacks by falsified fingerprints. Attackers can use malware to intercept biometric data from users and use them to access their accounts.

These cases highlight the significant threats posed by fingerprint system corruption to phone users. Therefore, it is important to protect these systems against external and internal threats while integrating advanced technologies to enhance security and reliability.

Current Trends and Developments in Fingerprint Biometrics

Fingerprint biometrics is a constantly evolving field. It seeks to improve the performance, reliability and security of existing systems. But it also develops new technologies and applications. Here are some current or expected trends and developments in this field.

  • Multimodality: it consists of combining several biometric modalities (fingerprint, face, iris, voice, etc.) to increase the level of security and reduce the risks of error or fraud. For example, some smartphones already offer authentication by fingerprint and facial recognition.
  • Contactless biometrics: it consists of capturing fingerprints without the need to touch a sensor. This technique avoids the problems related to the quality or contamination of fingerprints. And it improves the comfort and hygiene of users. For example, some airports already use contactless scanners to verify the identity of travelers.
  • Behavioral biometrics: it consists of analyzing the behavior of users when they interact with a biometric system. For instance, the way they place their finger on the sensor or the pressure they exert. This technique adds a dynamic factor to identification. And it detects attempts of impersonation or coercion. For example, some banking systems already use behavioral biometrics to reinforce the security of transactions.

Standards and Regulations for Fingerprint Systems

The use of fingerprint systems is subject to standards and regulations. They aim to ensure the quality, compatibility and security of biometric data. These standards and regulations can be established by international, national or sectoral organizations. Here are some examples of standards and regulations applicable to fingerprint systems.

  • The ISO/IEC 19794-2 standard: it defines the format of fingerprint data. It allows to store, exchange and compare fingerprints between different biometric systems. It specifies the technical characteristics, parameters and procedures to be respected to ensure the interoperability of systems.
  • The (EU) 2019/1157 regulation: it concerns the strengthening of the security of identity cards and residence permits issued to citizens of the European Union and their relatives. It provides for the mandatory introduction of two fingerprints in a digital medium integrated into the card. It aims to prevent document fraud and identity theft.
  • The Data Protection Act: it regulates the collection, processing and storage of personal data, including biometric data. It imposes on data controllers to respect the principles of lawfulness, fairness, proportionality, security and limited duration of data. It guarantees to data subjects a right of access, rectification and opposition to their data.

Examples of Good Practices for Fingerprint System Security

Fingerprint systems offer a convenient and effective way to authenticate people. But they are not without risks. It is important to adopt good practices to strengthen the security of fingerprint systems and protect the rights and freedoms of users. Here are some examples of good practices to follow by end users, businesses and governments.

  • For end users: it is recommended not to disclose their fingerprints to third parties, not to use the same finger for different biometric systems, and to check regularly the state of their fingerprints (cuts, burns, etc.) that may affect recognition. It is also advisable to combine fingerprint authentication with another factor, such as a password or a PIN or other trust criteria that allows the patented segmented key authentication technology developed by Freemindtronic in Andorra.
  • For businesses: it is necessary to comply with the applicable regulation on the protection of personal data, and to inform employees or customers about the use and purposes of fingerprint systems. It is also essential to secure biometric data against theft, loss or corruption, by using encryption, pseudonymization or anonymization techniques.
  • For governments: it is essential to define a clear and consistent legal framework on the use of fingerprint systems, taking into account ethical principles, fundamental rights and national security needs. It is also important to promote international cooperation and information exchange between competent authorities, in compliance with existing standards and conventions.

Responses to Attacks

Fingerprint systems can be victims of attacks aimed at bypassing or compromising their operation. These attacks can have serious consequences on the security of people, property or information.

Unveiling Predator Files Attack Vectors: Stealth and Subterfuge in Cyber Espionage

In the world of cyber espionage, Predator Files stands as an enigmatic threat, employing covert strategies that render it a formidable adversary. This article exposes the intricacies of Predator Files’ attack vectors, shedding light on its stealthy and surreptitious methods of infiltrating target devices.

Email: The Trojan Horse

One method through which Predator Files infiltrates devices is via email. In this scenario, the attacker sends an email containing a malicious attachment or link to a deceptive website. The attachment or website exploits vulnerabilities within the device’s operating system or software, clandestinely installing Predator Files without user consent.

Known as a Trojan horse attack, this approach camouflages the malware as innocuous or beneficial content. Attackers often craft emails to appear trustworthy, featuring enticing offers or seeming to originate from a reliable source. Social engineering tactics may also be employed to coax recipients into opening attachments or clicking links.

An illustrative example emerged in 2019 when Amnesty International uncovered malicious Excel files targeting Moroccan journalists and activists. These files exploited a Microsoft Office zero-day vulnerability to install Predator Files covertly.

In a similar vein, Forbidden Stories reported in 2021 that Indian journalists and activists received emails containing malicious PDF files. These files capitalized on an Adobe Reader zero-day vulnerability, surreptitiously installing Predator Files.

SMS Intrigue: Texts That Betray

Predator Files also leverages SMS as a means of infection. Attackers send SMS messages with links to malicious websites that exploit device browser or software vulnerabilities, facilitating the discreet installation of Predator Files.

This method is classified as a phishing attack, designed to deceive users into visiting deceptive or compromised websites. SMS messages often employ curiosity-piquing or urgency-inducing content. Spoofing techniques may be used to make the SMS appear genuine.

Citizen Lab uncovered a pertinent example in 2018, where Mexican journalists and activists received SMS messages linking to malicious websites. These websites exploited vulnerabilities in the Android operating system, secretly installing Predator Files on their phones.

Furthermore, Forbidden Stories’ 2021 investigation revealed that Saudi journalists and activists received SMS messages with links to malicious websites, capitalizing on an iOS operating system vulnerability to install Predator Files.

Web of Deceit: Navigating Vulnerabilities

Another avenue of infection is through the web. Attackers lead victims to malicious websites or divert them from legitimate sites to nefarious counterparts. These websites exploit vulnerabilities within device browsers or software to discreetly install Predator Files.

Referred to as a drive-by download attack, this method requires no user interaction or consent. Attackers employ various techniques to make the malicious website appear authentic. Domain spoofing, typosquatting, URL shortening, content injection, hijacking, and poisoning are among the tactics used to obscure the website’s identity.

Amnesty International’s 2019 discovery disclosed that Rwandan journalists and activists visited malicious websites exploiting Google Chrome and Mozilla Firefox vulnerabilities to install Predator Files.

Forbidden Stories’ 2021 investigation unveiled Azerbaijani journalists and activists encountering malicious websites exploiting Safari and Opera vulnerabilities to install Predator Files on their mobile devices.

WhatsApp’s Vulnerable Connection

Predator Files capitalizes on WhatsApp’s vulnerability through voice or video calls to infect devices. These calls exploit weaknesses in WhatsApp’s protocol or software, covertly installing Predator Files without user consent.

Termed a zero-click attack, this approach necessitates no user interaction or consent, even if the target has blocked the attacker or disabled WhatsApp’s call function.

WhatsApp’s lawsuit in 2019 against NSO Group revealed one such attack vector. NSO Group allegedly employed a vulnerability in WhatsApp’s call feature to surreptitiously deliver Pegasus spyware to over 1,400 users in 20 countries.

Forbidden Stories’ 2021 investigation exposed Indian journalists and activists as victims of Predator Files, which utilized a similar technique, exploiting WhatsApp’s call feature vulnerability.
