BITB Attacks: How to Avoid Phishing by iFrame

We have all seen phishing attacks aren’t uncommon, and they demand urgent attention with fake emails and messages at least once.. However, there’s much more in the cybersecurity landscape than just conventional email practices when it comes to phishing. Enterprises that don’t take the necessary precautions can suffer a death blow from a phishing attack. The top line is affected, but the brand’s image and trust can be obliterated if news of a data breach reaches the public.

The latest form of phishing scam is the browser in the browser attack (BITB) that simulates a browser window within a web browser and steals sensitive user information. A fraudulent pop-up window caters to the user and asks for their credentials to sign into the website in the previous web browser window, leading to identity theft.

This article explains what BITB attacks are and how they work, what the risks and consequences of BITB attacks are, how to prevent and protect yourself from BITB attacks using EviBITB technology, and how to install EviBITB on your web browser.

What are BITB attacks and how do they work?

BITB stands for Browser-In-The-Browser. This phishing technique creates a fake browser window within your web browser using HTML and CSS code. An iFrame of redirection, which is an invisible element that loads content from another URL, is displayed by this fake window. The iFrame of redirection mimics the appearance and functionality of a legitimate site, such as Google, Facebook, or Outlook, and asks you to enter your authentication information.

This fake window shows a legitimate URL in the address bar, as well as the icon and the title of the original site. That is the problem. Most users rely on checking the URL to verify the authenticity of a site. This makes it very difficult to detect the phishing attempt. This attack can affect you even if you use a secure connection (https).

BITB attacks can bypass many security measures that are designed to prevent phishing. That is why they are very dangerous. For example:

BITB attacks do not involve malicious links or domains. Anti-phishing software may fail to detect them because of that.
BITB attacks do not intercept your verification codes or tokens. Two-factor authentication may not protect you from them because of that.
Password managers may autofill your credentials on the fake window. They may not protect you from BITB attacks because of that.

Therefore, BITB attacks can allow hackers to access your accounts, steal your data, or even take over your identity. They pose a serious threat to your online security and privacy because of that.

How do BITB attacks work?

Two features of modern web development enable BITB attacks: single sign-on (SSO) options and iFrames.

Many websites embed SSO options that allow you to sign in using an existing account from another service, such as Google, Facebook, Apple, or Microsoft. This option is convenient because you do not need to create a new account or remember a new password for each website you visit.

iFrames are elements that can load content from another URL within a web page. They are often used for embedding videos, maps, ads, or widgets on websites.

The attackers do the following steps:

They make a phishing website with SSO options.
On their phishing website, they embed an iFrame of redirection that leads to their own server with a fake SSO window.
Using HTML and CSS code, they design their fake SSO window to imitate a browser window inside the browser.
They make their fake SSO window appear when you click on an SSO option on their phishing website.
With JavaScript code, they show a legitimate URL in the address bar of their fake SSO window.
Using OAuth methods, they request you to enter your credentials on their fake SSO window.
To their server, they send your credentials and then redirect you to the real website.

As you can see, BITB attacks are very deceptive and convincing. They can fool even savvy users who check the URL before entering their credentials.

What are the risks and consequences of BITB attacks?

BITB attacks are a serious threat. They can compromise data and identity for users and businesses. Users who fall victim to BITB attacks face these risks and consequences:

Their SSO account can be hijacked and all linked services accessed by the attacker.
Their personal and financial information can be stolen and used for identity theft, fraud or blackmail.
Their devices can be infected by malware or ransomware and their files damaged or encrypted.
Their online reputation can be tarnished by spamming or posting malicious content.

Businesses that offer SSO options are also vulnerable to BITB attacks. They can lose trust and loyalty from their customers or employees. Businesses that suffer a data breach due to BITB attacks face these risks and consequences:

Their customer or employee data can be exposed, exploited or sold by the attacker or the dark web.
Their brand image and reputation can be damaged by negative publicity and customer complaints.
Their legal and regulatory compliance can be violated by data protection laws and regulations.
Their revenue and profitability can be reduced by customer churn, lawsuits and fines.

Recent Examples of BITB Attacks

BITB attacks are not new, but they have become more sophisticated and widespread in recent years. Here are some examples of BITB attacks that targeted governmental entities:

In February 2020, Zscaler revealed a campaign of phishing BitB targeting users of Steam, a video game digital distribution service. The hackers created fake Counter-Strike: Global Offensive (CS: GO) websites that offered free skins or weapons for the game. These websites displayed a fake pop-up window that asked users to sign in with Steam. If users entered their credentials, they were sent to the hackers who could then access their Steam accounts and steal their items.
In March 2020, Bitdefender reported a campaign of phishing BitB targeting users of Office 365, a cloud-based suite of productivity applications. The hackers sent emails that pretended to be from Microsoft and asked users to update their Office 365 settings. These emails contained a link that led users to a fake Office 365 website that displayed a fake pop-up window that asked users to sign in with Office 365. If users entered their credentials, they were sent to the hackers who could then access their Office 365 accounts and steal their data.
In September 2020, Proofpoint uncovered a campaign of phishing BitB targeting users of Okta, a cloud-based identity and access management service. The hackers sent emails that pretended to be from various organizations and asked users to verify their Okta account. These emails contained a link that led users to a fake Okta website that displayed a fake pop-up window that asked users to sign in with Okta. If users entered their credentials, they were sent to the hackers who could then access their Okta account and compromise their other connected applications.

These examples show that BITB attacks can target any SSO provider and any website or web application that uses SSO. They also show that hackers can use various methods to lure users into clicking on malicious links or entering their credentials on fake windows.

What are some statistics on BITB attacks?

BITB attacks use iFrames to deceive users with fake SSO windows. Here are some statistics on BITB attacks:

According to Statista, the number of unique phishing sites detected worldwide reached 2.11 million in the third quarter of 2020, an increase of 10% from the previous quarter.
According to The Hacker News, BITB attacks can exploit third-party SSO options embedded on websites such as “Sign in with Google” (or Facebook, Apple, or Microsoft) to create fake browser windows within the browser and spoof legitimate domains.
According to Zscaler, BITB attacks have been used in the wild at least once before, in February 2020, to target Steam users by means of fake Counter-Strike: Global Offensive (CS: GO) websites.
According to NetSPI, the volume of successful phishing attacks on organizations worldwide in 2021 was highest in Brazil (25%), followed by India (17%), and Mexico (14%).
According to DZone, the most targeted industry sectors by phishing attacks as of the third quarter of 2020 were SaaS/Webmail (33%), Financial Institutions (22%), and Payment Services (14%).

How to effectively fight against BITB attacks?

BITB attacks are very hard to detect, but not impossible. There are some signs that can help you spot them and some measures that can help you prevent them. Here are some tips:

Always check the URL of the site before entering your credentials. Make sure it matches the domain of the site or the SSO provider that you want to use. Do not rely on the URL displayed on the pop-up window, as it can be fake.
Always check the SSL certificate of the site before entering your credentials. Make sure it is valid and issued by a trusted authority. Do not rely on the padlock icon displayed on the pop-up window, as it can be fake.
Always use an updated antivirus software and browser extension that can detect and block malicious sites and scripts. They can help you avoid landing on phishing pages or loading fake windows.
Always use strong and unique passwords for each site or application that you use. Do not reuse the same password for different accounts, as it can increase the risk of compromise if one of them is breached.
Always use two-factor authentication (2FA) for your accounts, especially those that you use for SSO. 2FA adds an extra layer of security by requiring a second factor (such as a code sent to your phone or email) to verify your identity. Having your username and password is less useful for hackers if they need your device or access to your email account too.

How to prevent and protect yourself from BITB attacks using EviBITB technology?

The best way to prevent and protect yourself from BITB attacks is to use EviBITB technology, a technology that allows you to detect and remove redirection iframes from web pages. EviBITB is integrated for free in the free and paid extensions of Freemindtronic that are compatible with NFC HSM devices that use a smartphone or an NFC HSM device. The latter stores encrypted multiple authentication information (username, password, otp) for secure authentication for any website on the internet or intranet.

EviBITB technology also has a system of automatic backup of the URL of connection to the account using a web browser to connect to an online account on the internet or intranet. This extension is paired with the NFC android phone which is itself paired with an NFC HSM where encrypted detailed authentication information such as username, password, and secret keys OTP (TOP or HOTP) are stored. Thus, before authorizing auto-filling of connection fields or auto-connection to an online account, the phone will check beforehand if the connection URL is compliant (sandbox technique). This system adds to EviBITB protection.(click here to learn more about EviBITB)

By using EviBITB technology, you can enjoy many benefits:

You can avoid falling victim to BITB attacks that can steal your data or compromise your identity.

Snake: The Russian malware that steals sensitive information for 20 years

The origin of the name Snake

The malware authors named the malware Snake themselves, as it appears in the data that Snake exfiltrates from compromised systems. It is also known by the names Uroboros, Turla, Venomous Bear or Waterbug. These names are used by different security researchers or vendors to refer to the same malware family.

The Mac version of Snake malware

In 2017, security researchers discovered a Mac version of Snake malware. It had many similarities with the Windows version, such as the use of encryption and fragmentation for communication, the ability to execute commands and download modules, and the presence of the name “Snake” in the exfiltrated data. However, it also had some differences, such as the use of a fake Adobe Flash Player installer to infect systems, the use of a launch daemon to achieve persistence, and the use of a Python script to run the main payload. The Mac version of Snake malware showed that the FSB was expanding its target range to include Mac users.

What is Snake?

Snake is a malware that implants itself on infected systems and steals confidential information, such as documents, communications or credentials. It is implemented in the .NET programming language and uses custom communication protocols that employ encryption and fragmentation to ensure confidentiality and avoid detection. It is capable of spreading on local networks and bypassing security measures.

The name Snake comes from the name that the malware authors gave it themselves, as it appears in the data that Snake exfiltrates from compromised systems ¹. It is also known by the names Uroboros, Turla, Venomous Bear or Waterbug.

The technical features of Snake

Snake is implemented in the .NET programming language and custom communication protocols with encryption and fragmentation are the tools that Snake uses to ensure confidentiality and avoid detection. It is capable of spreading on local networks and bypassing security measures. It can also execute commands on infected systems and download additional modules or payloads.

Another variant of Snake malware is Snake ransomware, also known as Ekans. This variant targets manufacturers and industrial control systems. It can infect an entire network before activating and encrypting files. It also attempts to stop processes related to industrial control systems, such as SCADA and HMI software. This can cause serious disruption and damage to critical infrastructure. Snake malware as a ransomware threat demands a ransom in Bitcoin to decrypt the files. Some of its victims include Honda and Enel Group.

How does Snake work?

Snake works by creating a covert peer-to-peer (P2P) network of many infected computers worldwide. Many of these systems serve as relay nodes that route disguised operational traffic to and from Snake implants on the FSB’s final targets. Thus, Snake creates an almost undetectable way to transmit stolen information to Russia.

Snake mainly targets sectors of interest for Russian intelligence, such as governments, research facilities, journalists, or financial and technological sectors. Among the identified victims are NATO member countries, media and educational organizations in the United States, or critical infrastructure sectors such as government facilities, financial services, critical manufacturing or communications ².

Snake has been used by the FSB since 2004 and has undergone numerous adaptations and revisions to remain viable after several public disclosures and other mitigation measures ². On the computers it has compromised, the Snake implant persists indefinitely on the system, usually without being detected by the owner or authorized users of the system ³.

The disclosure and disruption of Snake

On May 9, 2023, the Cybersecurity and Infrastructure Security Agency (CISA) and its partners issued a joint advisory to disclose the threat of Snake malware. The advisory provides technical descriptions of the malware’s host architecture and network communications, and mitigations to help detect and defend against this threat. On the same day, the US Department of Justice announced the completion of a court-authorized operation, code-named MEDUSA, to disrupt a global peer-to-peer network of computers compromised by Snake malware.

An example of technical analysis of Snake malware

To illustrate how Snake malware works in detail, we will use an example of technical analysis conducted by FortiGuard Labs on a fresh variant of Snake keylogger malware. This variant was captured in November 2021 and was delivered as an Excel file with malicious macro code. The main payload of Snake keylogger malware was an executable file named “Requests07520000652.exe”, which the macro code downloaded and executed

Snake malware’s core component

Several embedded resources were contained in the main payload, which was a .NET assembly file. Reflection loaded another .NET assembly file named “Guna.UI2.dll” into memory, which was one of theml”, which was loaded into memory by reflection. This file contained the core functionality of Snake keylogger malware, such as stealing information, taking screenshots, capturing clipboard data, and communicating with a command and control (C2) server.

How Snake malware steals sensitive data

The information stealing module was responsible for collecting various types of sensitive information from the infected system, such as:

System information: computer name, user name, operating system version, processor architecture, etc.
Saved credentials: passwords stored in browsers (Chrome, Firefox, Edge), email clients (Outlook), FTP clients (FileZilla), etc.
Keystrokes: keyboard input from various applications (browsers, email clients, chat programs, etc.)
Screenshots: images of the desktop or active window at regular intervals
Clipboard data: text or images copied to the clipboard

Snake stored the collected information in a temporary folder with random names and encrypted it with AES.

How Snake malware communicates with its operators

After the previous subsection, you can add this subsection:

The communication module was responsible for sending the encrypted information to a C2 server and receiving commands from it. The C2 server used a domain name that was generated by an algorithm based on the current date. The communication protocol used HTTP POST requests with custom headers and parameters. Snake encoded the data with Base64 and encrypted it with AES.

Some of the commands that the C2 server could send to the malware were:

GetInfo: request system information from the malware
GetLogs: request keystroke logs from the malware
GetClipboard: request clipboard data from the malware
GetScreen: demander des captures d’écran du malware
Mise à jour : téléchargez et exécutez une version mise à jour du malware
Désinstaller: supprimer le malware du système

How Operation MEDUSA neutralized Snake

After the previous paragraph, you can add this subsection:

Operation MEDUSA used a tool created by the FBI named PERSEUS, which issued commands that caused the Snake malware to overwrite its own vital components. This effectively disabled the malware on infected computers and prevented it from communicating with other nodes or exfiltrating data. The operation also seized several domains used by Snake to communicate with its infrastructure.

How to mitigate against Snake

After the previous subsection, you can add this subsection:

The joint advisory from CISA and its partners provides several recommendations to mitigate against Snake malware. These include:

Updating antivirus software and scanning for indicators of compromise (IOCs)
Implementing network segmentation and firewall rules
Applying security patches and updates
Enforcing strong password policies and multi-factor authentication
Disabling unnecessary services and ports
Educating users about phishing and social engineering
Reporting any suspicious activity or incidents to CISA or law enforcement

How to detect Snake?

The detection of Snake can be difficult due to its high level of stealth and its use of custom protocols. However, there are some ways to identify the presence of the malware on a system or a network.

On the infected system, it is possible to spot a Windows service named “Windows Error Reporting Service” that is not the legitimate service of the same name. This malicious service executes a file WerFault.exe hidden among the many valid Windows WerFault.exe files in the %windows%WinSxS directory. This file is responsible for decrypting and loading Snake’s components into memory ².
On the infected network, it is possible to use network intrusion detection systems (NIDS) to identify some of the custom communication protocols of Snake, such as UDP with XOR fragmentation or TCP with RC4 encryption. These protocols are described in detail in the joint warning issued by partner agencies ².

How extensive is Snake infection?

According to partner agencies that issued the joint warning on Snake, malware infrastructure has been identified in more than 50 countries across North America, South America, Europe, Africa, Asia and Australia, including the United States and Russia itself ². Although Snake uses infrastructure across all industries, its targeting is purposeful and tactical. Globally, the FSB has used Snake to collect sensitive intelligence from high-priority targets, such as government networks, research facilities and journalists. For example, FSB actors used Snake to access and exfiltrate sensitive international relations documents, as well as other diplomatic communications, from a victim in a NATO country ². In the United States, the FSB has affected sectors such as education, small businesses and media organizations, as well as critical infrastructure sectors such as government facilities, financial services, critical manufacturing and communications ².

Snake: All its features to collect sensitive data on compromised systems

Snake has a set of features that allow it to collect various sensitive data on compromised systems. Among these features are:

The ability to execute arbitrary commands remotely on the infected system.
The ability to download or upload files from or to the infected system.
The ability to enumerate or modify Windows registry keys or values.
The ability to enumerate or modify files or directories present on the infected system.
The ability to enumerate or modify processes or services running on the infected system.
The ability to capture screenshots of the infected system.
The ability to record keystrokes (keylogging) on the infected system.
The ability to collect various information about the infected system, such as its hostname, IP address, username or password ¹.

What are the statistics on Snake malware?

There are no official statistics on the exact number of computers infected by Snake or on the amount of information stolen by malware. However, we can rely on some indicators to get an approximate idea of the scale of phenomenon.

What are technical characteristics of snake?

Snake is a feature-rich malware that poses a significant threat to users’ privacy and security. Some of its technical characteristics are:

It is implemented in .NET programming language and uses custom communication protocols that employ encryption and fragmentation for confidentiality and avoid detection.
It consists of several components that are encrypted and stored either in files or registry keys on infected systems. These components are decrypted and loaded into memory at runtime by a loader component.
It uses different techniques for persistence on infected systems, such as creating malicious Windows services or modifying legitimate ones.
It uses different techniques for stealth on infected systems, such as hiding its files among valid Windows files or using steganography to hide its malicious code in PNG images.
It uses different techniques for propagation on local networks, such as exploiting vulnerabilities or using stolen credentials.
It uses different techniques for exfiltration of stolen data from infected systems, such as using custom UDP or TCP protocols with encryption or fragmentation, or using legitimate applications such as Telegram ¹ ².

How can you prevent snake from stealing your sensitive data?

To prevent snake from stealing your sensitive data , you should follow some best practices in terms of computer security . These include :

Regularly update operating systems and applications with latest security patches .
Use effective antivirus and antimalware solutions and keep them up date .

Message reçu. Here is the same article in English, with some additions on how to prevent Snake from stealing your sensitive data, the technical characteristics of Snake, the consequences of data theft by the malware, and the impact of Snake on businesses and governments. # Snake: The Russian malware that steals sensitive information for 20 years Snake is a malware that allows Russian intelligence services to collect and transmit sensitive information from hundreds of infected computers across 50 countries. It is a very sophisticated espionage tool, designed and used by Center 16 of the Federal Security Service of the Russian Federation (FSB) for long-term operations on strategic targets. ## What is Snake? Snake is a malware that implants itself on infected systems and steals confidential information, such as documents, communications or credentials. It is implemented in the .NET programming language and uses custom communication protocols that employ encryption and fragmentation to ensure confidentiality and avoid detection. It is capable of spreading on local networks and bypassing security measures. The name Snake comes from the name that the malware authors gave it themselves, as it appears in the data that Snake exfiltrates from compromised systems. It is also known by the names Uroboros, Turla, Venomous Bear or Waterbug. ## How does Snake work? Snake works by creating a covert peer-to-peer (P2P) network of many infected computers worldwide. Many of these systems serve as relay nodes that route disguised operational traffic to and from Snake implants on the FSB’s final targets. Thus, Snake creates an almost undetectable way to transmit stolen information to Russia. Snake mainly targets sectors of interest for Russian intelligence, such as governments, research facilities, journalists, or financial and technological sectors. Among the identified victims are NATO member countries, media and educational organizations in the United States, or critical infrastructure sectors such as government facilities, financial services, critical manufacturing or communications. Snake has been used by the FSB since 2004 and has undergone numerous adaptations and revisions to remain viable after several public disclosures and other mitigation measures. On the computers it has compromised, the Snake implant persists indefinitely on the system, usually without being detected by the owner or authorized users of the system. ## How to detect Snake? The detection of Snake can be difficult due to its high level of stealth and its use of custom protocols. However, there are some ways to identify the presence of the malware on a system or a network. – On the infected system, it is possible to spot a Windows service named “Windows Error Reporting Service” that is not the legitimate service of the same name. This malicious service executes a file WerFault.exe hidden among the many valid Windows WerFault.exe files in the %windows%WinSxS directory. This file is responsible for decrypting and loading Snake’s components into memory. – On the infected network, it is possible to use network intrusion detection systems (NIDS) to identify some of the custom communication protocols of Snake, such as UDP with XOR fragmentation or TCP with RC4 encryption. These protocols are described in detail in the joint warning issued by partner agencies. ## How extensive is Snake infection? According to partner agencies that issued the joint warning on Snake, malware infrastructure has been identified in more than 50 countries across North America, South America, Europe, Africa, Asia and Australia, including the United States and Russia itself. Although Snake uses infrastructure across all industries, its targeting is purposeful and tactical. Globally, the FSB has used Snake to collect sensitive intelligence from high-priority targets, such as government networks, research facilities and journalists. For example, FSB actors used Snake to access and exfiltrate sensitive international relations documents, as well as other diplomatic communications, from a victim in a NATO country. In the United States, the FSB has affected sectors such as education, small businesses and media organizations, as well as critical infrastructure sectors such as government facilities, financial services, critical manufacturing and communications. ## Snake: All its features to collect sensitive data on compromised systems Snake has a set of features that allow it to collect various sensitive data on compromised systems. Among these features are: – The ability to execute arbitrary commands remotely on the infected system. – The ability to download or upload files from or to the infected system. – The ability to enumerate or modify Windows registry keys or values. – The ability to enumerate or modify files or directories present on the infected system. – The ability to enumerate or modify processes or services running on the infected system. – The ability to capture screenshots of the infected system. – The ability to record keystrokes (keylogging) on the infected system. – The ability to collect various information about the infected system, such as its hostname, IP address, username or password. ## What are the statistics on Snake malware? There are no official statistics on the exact number of computers infected by Snake or on the amount of information stolen by malware. However, we can rely on some indicators to get an approximate idea of the scale of phenomenon. – According to Cybereason , a cybersecurity company that analyzed a variant of malware in 2020 , Snake was distributed via a massive campaign malicious emails that affected more than 100 , 000 recipients in more than 30 countries [ ^1 ^ ] . – According to CISA , a US agency responsible for cybersecurity and security critical infrastructures that published a joint warning with several partners in 2023 , infrastructure malware has been identified in more than 50 countries across six continents [ ^2 ^ ] . – According to CBS News , an American media outlet that reported operation conducted by FBI to neutralize network Snake in United States in 2023 , malware was used for 20 years by FSB to collect sensitive intelligence from hundreds of infected computers [ ^3 ^ ] . ## What are technical characteristics of snake? Snake is a feature-rich malware that poses a significant threat to users’ privacy and security. Some of its technical characteristics are: – It is implemented in .NET programming language and uses custom communication protocols that employ encryption and fragmentation for confidentiality and avoid detection. – It consists of several components that are encrypted and stored either in files or registry keys on infected systems. These components are decrypted and loaded into memory at runtime by a loader component. – It uses different techniques for persistence on infected systems, such as creating malicious Windows services or modifying legitimate ones. – It uses different techniques for stealth on infected systems, such as hiding its files among valid Windows files or using steganography to hide its malicious code in PNG images. – It uses different techniques for propagation on local networks, such as exploiting vulnerabilities or using stolen credentials. – It uses different techniques for exfiltration of stolen data from infected systems, such as using custom UDP or TCP protocols with encryption or fragmentation, or using legitimate applications such as Telegram . ## How can you prevent snake from stealing your sensitive data? To prevent snake from stealing your sensitive data , you should follow some best practices in terms of computer security . These include : – Regularly update operating systems and applications with latest security patches . – Use effective antivirus and antimalware solutions and keep them up date . – Enable firewall and configure strict rules limit incoming outgoing traffic . – Apply principle least privilege limit access sensitive data only authorized users . – Educate users risks related unsolicited suspicious emails attachments . – Perform regular backups important data store them offline secure location . – Monitor anomalies suspicious activities networks report any potential incident . For more information snake how protect yourself it , you can consult joint warning issued by intelligence cybersecurity agencies [ ^2 ^ ] threat analysis report published by Cybereason [ ^1 ^ ] . ## How can you remove snake from your system? To remove snake from your system , you should follow some steps : – Disconnect your system from network prevent further communication with snake infrastructure . – Scan your system with updated antivirus antimalware tools detect remove any traces snake components . – Restore your system previous clean state using backups restore points . – Change passwords any accounts may have been compromised snake . – Report incident relevant authorities seek professional help needed .

How does Snake spread precisely?

Snake spreads precisely by using different techniques to infect systems and networks. Some of these techniques are:

Exploiting vulnerabilities in software or hardware to gain access to systems or networks. For example, Snake used a Microsoft Word vulnerability (CVE-2017-11882) to deliver malicious documents to victims in Central and Eastern Europe ¹.
Using phishing emails with malicious attachments or links to trick users into opening or downloading Snake. For example, Snake used a massive email campaign that targeted more than 100,000 recipients in more than 30 countries with PNG images that contained hidden malicious code ².
Using stolen credentials or brute-force attacks to log into systems or networks. For example, Snake used credentials stolen from other malware campaigns or from keylogging to access systems or networks of interest ¹.
Using lateral movement techniques to spread within a network. For example, Snake used tools such as Mimikatz, PsExec or WMI to move from one system to another within a network ¹.
Using covert peer-to-peer (P2P) network to communicate with other infected systems and relay nodes. For example, Snake used custom UDP or TCP protocols with encryption and fragmentation to transmit data to and from its command and control servers ¹.

Source : CVE Details – CVE-2023-32784

✦ Impacts immédiats

D’une part, la compromission devient un état durable du terminal, et non un incident ponctuel. Une fois que les artefacts mémoire ont été extraits, il est difficile de garantir que le système n’est plus compromis.
D’autre part, les agents de sécurité logiciels perdent leur capacité à prouver qu’ils fonctionnent correctement sur un environnement potentiellement compromis.
Par conséquent, l’attribution et la réponse deviennent plus incertaines, tandis que la fenêtre d’exposition s’allonge.

Source : NIST Cybersecurity Framework

⚠ Message stratégique

Cependant, l’élément clé n’est pas seulement la vulnérabilité en elle-même, mais la logique de la confiance : un système compromis, même sans signature connue, ne peut plus garantir une sécurité fiable. La confiance dans un environnement où les secrets sont stockés devient fragile si ces secrets sont vulnérables à une exfiltration discrète via la mémoire.

Source : NIST Special Publication 800-53: Security and Privacy Controls for Information Systems and Organizations

🛑 Quand ne pas agir

Tout d’abord, ne réintroduisez pas de secrets (identifiants, clés, données sensibles) sur un terminal dont l’intégrité n’est pas attestée.
Ensuite, n’empilez pas des couches de sécurité logicielle qui peuvent compliquer l’audit et étendre la surface d’attaque.
Enfin, ne confondez pas retour au service et restauration de confiance : une reprise rapide peut masquer des compromissions persistantes.

✓ Principe de contre-espionnage souverain

Ainsi, la réduction du risque ne consiste pas à “nettoyer” un système compromis, mais à déplacer la confiance hors du périmètre compromis : hors OS, hors mémoire, et si nécessaire hors réseau. Cela garantit que les secrets restent protégés même si l’environnement principal du système est compromis.

Résumé avancé — Comprendre la vulnérabilité CVE-2023-32784

⮞ Reading Note

D’abord, ce résumé avancé propose une analyse détaillée de la vulnérabilité CVE-2023-32784, ses implications techniques et les risques d’exfiltration de secrets à travers des artefacts de mémoire comme les fichiers d’hibernation et de pagination. Ensuite, la chronique complète fournira des stratégies pratiques pour minimiser l’impact de cette vulnérabilité, y compris les solutions de sécurité robustes comme PassCypher.

Exploitation de CVE-2023-32784 — L’attaque Zero-Day sur les secrets numériques

Tout d’abord, il est essentiel de comprendre comment la vulnérabilité CVE-2023-32784 peut être exploitée. Cette faille permet à un attaquant d’accéder à des secrets numériques stockés dans des fichiers mémoire sensibles, comme les fichiers d’hibernation (hiberfil.sys) et de pagination (pagefile.sys). Ces fichiers peuvent contenir des informations critiques, telles que des mots de passe, des clés de chiffrement et d’autres secrets utilisateurs.

Dump mémoire et vulnérabilités de pagefile

Les fichiers d’hibernation et de pagination sont des composants essentiels pour la gestion des ressources système dans les environnements Windows. Cependant, ces fichiers peuvent devenir des cibles privilégiées pour les attaquants, car ils contiennent des portions de la mémoire du système, qui peuvent inclure des secrets non chiffrés.

En effet, lorsque des informations sensibles sont présentes dans la mémoire, elles sont souvent écrites dans ces fichiers sans aucune forme de protection, ce qui les rend vulnérables à l’accès non autorisé. Une fois cette vulnérabilité exploitée, un attaquant peut extraire ces secrets et les utiliser à des fins malveillantes, comme le vol d’identifiants ou l’accès à des systèmes sécurisés.

Hiberfil et exfiltration de données sensibles

Un autre vecteur d’attaque majeur est l’exfiltration des secrets stockés dans le fichier hiberfil.sys. Ce fichier, utilisé pour la gestion des états de mise en veille prolongée, contient une copie complète du contenu de la mémoire vive. Par conséquent, si un attaquant parvient à accéder à ce fichier, il peut facilement y extraire des données sensibles.

Cependant, l’utilisation de solutions de sécurité comme PassCypher permet de chiffrer ces fichiers mémoire sensibles, de manière à empêcher l’exfiltration de données en cas de compromission.

Protéger vos secrets : PassCypher NFC HSM

PassCypher NFC HSM protège vos secrets numériques en les stockant en dehors du système d’exploitation compromis, avec un chiffrement segmenté et un authentification sans contact NFC. Ces mécanismes offrent une protection maximale contre les attaques de type CVE-2023-32784, qui exploitent les vulnérabilités dans les fichiers mémoire sensibles comme hiberfil.sys et pagefile.sys. Grâce à ces technologies, même en cas de compromission du système d’exploitation, vos secrets restent protégés.

Par conséquent, cette solution offre une couche supplémentaire de protection qui limite les risques associés aux attaques zero-day, tout en permettant une gestion de la sécurité des données au niveau physique et réseau, en dehors du périmètre OS compromis.

Recommandations stratégiques pour la gestion de CVE-2023-32784

Les entreprises et les utilisateurs doivent mettre en place des stratégies de défense multi-couches pour contrer les risques liés à cette vulnérabilité. Voici quelques recommandations stratégiques :

Chiffrez les fichiers d’hibernation et de pagination : Cela permet d’empêcher l’accès non autorisé aux informations sensibles stockées dans la mémoire système.
Utilisez des solutions de protection avancées : Comme PassCypher, qui protège vos secrets, même en dehors du système d’exploitation.
Surveillez les accès aux fichiers mémoire sensibles : Mettre en place une surveillance continue des fichiers d’hibernation et de pagination pour détecter toute tentative d’accès non autorisé.
Revue des mécanismes de stockage sécurisé : Utiliser des solutions de stockage sécurisé hors du périmètre système pour les données sensibles, telles que des clés physiques NFC ou des dispositifs de stockage chiffrés.

En résumé, la protection des secrets sensibles dans un environnement numérique devient une priorité à mesure que les vulnérabilités comme CVE-2023-32784 sont découvertes et exploitées. PassCypher se présente comme une solution de défense efficace, mais il est essentiel de maintenir une approche proactive de la sécurité en appliquant des mesures de prévention et en intégrant des outils robustes dans l’architecture de votre système de sécurité.

Transition
À présent, la chronique complète détaillera les implications à long terme de cette vulnérabilité et la manière dont des solutions comme PassCypher contribuent à sécuriser les systèmes dans un environnement numérique en constante évolution.

Chronique complète — Comprendre et contrer CVE-2023-32784

D’abord, cette chronique complète explore en profondeur la vulnérabilité CVE-2023-32784 et ses impacts sur la sécurité numérique. Ensuite, nous examinerons les mécanismes de cette faille et les meilleures pratiques pour la prévenir. Vous découvrirez également comment des solutions comme PassCypher peuvent vous protéger.

Analyse de CVE-2023-32784 : Une faille critique dans la gestion de la mémoire

La vulnérabilité CVE-2023-32784 est liée à une faille dans la gestion de la mémoire des systèmes informatiques. Les artefacts de mémoire, tels que les fichiers d’hibernation (hiberfil.sys) et de pagination (pagefile.sys), peuvent contenir des informations sensibles. Ces fichiers, utilisés pour améliorer la performance du système, deviennent une cible idéale pour les attaquants.

En effet, ces fichiers peuvent stocker des secrets tels que des identifiants, des clés de chiffrement et d’autres informations sensibles. Une fois extraites, ces données peuvent être utilisées pour des attaques malveillantes. Ce phénomène représente un risque majeur pour la confidentialité des entreprises.

Oui : des failles liées à la mémoire existent toujours

Les vulnérabilités qui exposent des secrets numériques en mémoire — que ce soit dans :

le fichier d’hibernation (hiberfil.sys),
le fichier de pagination (pagefile.sys),
ou même la mémoire RAM active —

continuent d’être une préoccupation réelle en 2025–2026.

Cela tient à la nature fondamentale de l’informatique : pour exécuter des programmes, des données sensibles doivent parfois vivre temporairement en mémoire vive, y compris des clés, mots de passe ou jetons d’authentification. C’est un risque inhérent, et pas une vulnérabilité ponctuelle unique.

Comment ces classes de failles se manifestent aujourd’hui

Exfiltration mémoire

C’est une classe d’attaque où un attaquant accède à la mémoire ou à des artefacts système pour extraire des secrets. Ce type d’attaque peut se produire par :

Dump mémoire (extraction complète de la RAM)
Accès aux fichiers d’échange/pagination
Débogage accessible
Malware avec privilèges élevés
Exploits zero-day dans le système d’exploitation ou dans des pilotes

Même si un patch corrige une vulnérabilité spécifique, un autre vecteur mémoire pourrait être exploité tant que des données sensibles transitent en clair en mémoire.

Failles Zero-Day plus larges

Chaque année, de nouvelles vulnérabilités de type zero-day sont découvertes. Certaines permettent à un attaquant de lire la mémoire ou d’intercepter des secrets en clair — indépendamment des fichiers d’hibernation/pagination. Par exemple :

Failles dans le noyau OS
Failles dans des pilotes systèmes
Failles dans des outils de virtualisation
Failles dans des gestionnaires de mémoire

La simplicité d’exécution varie, mais l’effet potentiel reste : exfiltration de données sensibles en mémoire.

Fuites de mémoire dans les applications

Beaucoup de logiciels, notamment ceux lisant des secrets et clés, ont encore :

des buffers non nettoyés
des allocations de mémoire non effacées
des chaînes sensibles laissées en clair en RAM

Même des produits modernes peuvent présenter ce type de risque si l’accès à la mémoire n’est pas strictement géré.

Évolution des contre‑mesures en 2025–2026

Les éditeurs ont continué à améliorer les protections :

Chiffrement renforcé en mémoire
Windows utilise Virtual Secure Mode,
Linux intègre des distributions avec protections renforcées (SELinux, AppArmor),
et macOS a des protections en écriture de la mémoire (AMFI).

Mais aucune mesure n’élimine complètement la mémoire non chiffrée tant que des secrets y transitent en clair.

Caractéristiques modernes de mitigation

Mitigation	But
Memory encryption (TPM/SEV/SME)	Chiffrement de la mémoire vive en hardware
ASLR / CFG / DEP	Mitigation d’exploitation d’applications
Credential Guard (Windows)	Isolation des secrets dans un conteneur protégé
Kernel hardening	Réduction des vecteurs d’exploitation

Ces technologies réduisent les risques mais ne les éliminent pas complètement.

Exemples récents (2024–2026)

Bien qu’aucune faille ne soit exactement identique à CVE-2023-32784, plusieurs vulnérabilités récentes ont montré que :

des secrets pouvaient être extraits via des attaques mémoire
des clés sensibles pouvaient être récupérées si elles furent stockées non protégées en RAM.

Par exemple, dans les années 2024–2025, il y a eu :

Vulnérabilités dans les hyperviseurs permettant d’accéder à la mémoire VM
Exploits dans des outils de conteneurs laissant les secrets en mémoire
Défaillances de sécurité dans certains antivirus ou outils de diagnostic exposant la mémoire

Ces vulnérabilités sont souvent classées CVE avec des amplitudes différentes mais une conséquence similaire : données sensibles en mémoire exposées.

Leçons et bonnes pratiques durables

Ce qui cause encore des risques aujourd’hui :

Les programmes stockant des secrets en clair
Les dumps mémoire accessibles à un attaquant
Les processus mal isolés
Les privilèges inadéquats

Source pour l’évolution des failles mémoire :

Chiffrez toutes les informations sensibles : Utilisez des solutions robustes pour protéger les secrets dans la mémoire et les fichiers système.
Appliquez une sécurité multi-couches : Combinez des stratégies physiques et logiques pour renforcer la protection des secrets numériques.
Optez pour un stockage sécurisé : Protégez vos secrets avec des dispositifs comme PassCypher NFC, stockés hors du système compromis.
Surveillez les fichiers sensibles : Mettez en place une surveillance continue des fichiers tels que hiberfil.sys et pagefile.sys pour détecter toute tentative d’accès non autorisé.
Formez vos équipes : Sensibilisez vos équipes à la sécurité des secrets et à la gestion proactive des attaques zero-day.

Résilience et défense contre les attaques zero-day

Face aux attaques zero-day, il est essentiel de renforcer la résilience des systèmes. La protection ne se limite pas aux failles connues, mais inclut aussi la préparation face aux menaces inconnues. Une approche proactive de la sécurité est cruciale, intégrant des outils avancés comme le chiffrement et la gestion des secrets hors OS.

En résumé, une défense multi-couches et proactive est primordiale pour se prémunir contre les attaques complexes et persistantes.

À présent, explorez la section suivante sur les solutions de détection des failles CVE, où nous détaillerons les stratégies de détection avancée des vulnérabilités et des attaques zero-day pour renforcer la résilience de vos systèmes.

L’Impact de CVE-2023-32784 sur la Confidentialité des Utilisateurs

L’exploitation de CVE-2023-32784 met en lumière un problème majeur concernant la confidentialité des informations personnelles et professionnelles. Les artefacts mémoire, tels que les fichiers d’hibernation (hiberfil.sys) et de pagination (pagefile.sys), peuvent contenir des données sensibles. Si un attaquant parvient à y accéder, il peut récupérer des informations critiques, souvent sans que la victime ne le sache. Ce genre de compromission peut impacter la réputation des entreprises et entraîner des pertes financières.

Une étude menée par le Ponemon Institute sur le coût des violations de données révèle que les entreprises dépensent en moyenne 3,86 millions de dollars pour une violation de données, ce qui montre l’ampleur de l’impact financier pour une organisation.

Les Meilleures Pratiques pour Contourner les Failles Zero-Day

Face à la nature insidieuse des attaques zero-day, il est essentiel pour les entreprises de prendre des mesures proactives pour éviter de devenir une cible. Cela inclut non seulement l’application régulière de mises à jour et de correctifs mais aussi l’adoption de stratégies de défense en profondeur qui rendent difficile l’accès à des secrets numériques, même si un attaquant parvient à exploiter une vulnérabilité inconnue.

Des pratiques telles que la gestion rigoureuse des clés de chiffrement et le chiffrement des fichiers mémoire sensibles (hiberfil.sys, pagefile.sys) peuvent réduire le risque d’exploitation de CVE-2023-32784. CIS Controls recommande des stratégies de sécurité efficaces pour la gestion des risques liés à ces vulnérabilités.

La Sécurisation de la Mémoire du Système : Un Combat Permanent

Les fichiers mémoire, comme hiberfil.sys et pagefile.sys, sont des éléments critiques pour le fonctionnement des systèmes Windows. Toutefois, leur gestion pose un dilemme pour les administrateurs en matière de sécurité. En effet, bien qu’ils améliorent les performances du système, leur contenu peut être utilisé à des fins malveillantes si une vulnérabilité est exploitée.

Les meilleures pratiques de sécurité recommandent de désactiver les fichiers d’hibernation et de pagination lorsque cela est possible. Si ces fichiers doivent être utilisés, leur chiffrement doit être appliqué pour assurer qu’aucune donnée sensible n’est exposée lors d’une intrusion.

Tout d’abord, il est essentiel de comprendre comment la vulnérabilité CVE-2023-32784 peut être exploitée. Cette faille permet à un attaquant d’accéder à des secrets numériques stockés dans des fichiers mémoire sensibles, comme les fichiers d’hibernation (hiberfil.sys) et de pagination (pagefile.sys). Ces fichiers peuvent contenir des informations critiques telles que des mots de passe, des clés de chiffrement et d’autres secrets utilisateurs.

En effet, les attaquants peuvent utiliser cette vulnérabilité pour exfiltrer des données sans laisser de traces visibles, rendant l’attaque difficile à détecter jusqu’à ce que des informations sensibles aient déjà été compromises. Cette exploitation rend la compromission d’autant plus insidieuse et difficile à contrer avec les mécanismes de sécurité traditionnels.

Hiberfil et exfiltration de données sensibles

Exfiltration de données sensibles via la mémoire : un risque pour tous les gestionnaires de mots de passe

La faille CVE-2023-32784 dans KeePass est un exemple de ce que l’on appelle une vulnérabilité de “dump mémoire”, où un attaquant peut récupérer un mot de passe maître depuis la mémoire d’un système compromis. Bien que cette vulnérabilité concerne directement KeePass, elle met en lumière un problème plus large qui touche tous les logiciels qui manipulent des données sensibles telles que des mots de passe, des clés de chiffrement et des tokens d’authentification.

Gestionnaires de mots de passe et logiciels vulnérables

Bien que la vulnérabilité CVE-2023-32784 soit spécifique à des attaques d’exfiltration via des artefacts mémoire (hiberfil.sys et pagefile.sys), d’autres gestionnaires de mots de passe, tels que Bitwarden, LastPass, et Dashlane, peuvent également être vulnérables à des attaques de clickjacking et exploitation DOM lorsqu’ils utilisent des extensions de navigateur non sécurisées. Ces vulnérabilités peuvent permettre à un attaquant de manipuler les données sensibles via l’interface du navigateur, bien que la gestion en mémoire des données sensibles dans ces outils soit généralement protégée par des mécanismes de chiffrement.
Cependant, les fichiers mémoire (hiberfil.sys, pagefile.sys) restent une cible théorique pour les attaquants si les données ne sont pas correctement protégées en mémoire. Bien que ces gestionnaires chiffrent généralement les données stockées, la mémoire volatile (RAM), où les informations sont temporairement stockées pendant une session active, reste une cible potentielle si elle n’est pas correctement sécurisée.

ViperSoftX: The Malware that Steals Your Cryptocurrencies and Passwords

ViperSoftX is a malware that steals sensitive information from infected computers, including data related to cryptocurrencies and passwords. It was first discovered in 2020 as a JavaScript-based remote access trojan and cryptocurrency hijacker. Since then, it has evolved to become more sophisticated and stealthy, using innovative arrival and execution techniques, enhanced encryption and a malicious extension for web browsers. In this article, we will examine the features, targets and consequences of ViperSoftX malware, as well as how to protect yourself from it.

Global impact of ViperSoftX malware

This is not a regional threat, but a global one. The malware is mostly spread via torrents and software-sharing sites, which attract users from all over the world. According to Avast, the most impacted countries by ViperSoftX in 2022 were India, USA, Italy, and Brazil. However, Trend Micro reported that the malware also affected a significant number of victims in Australia, Japan, Taiwan, Malaysia and France in 2023. Both enterprises and consumers are at risk of losing their sensitive data and cryptocurrencies to this stealthy malware. Therefore, it is important to raise awareness about the dangers of ViperSoftX and how to prevent its infection.

How to avoid ViperSoftX, the malware that steals your sensitive data

This is malware is dangerous malware that targets Chrome and other browsers, and can steal your passwords from virtual password managers like 1Password or KeePass 2 and virtual cryptocurrency wallets. In this article, you will learn how it works and how to prevent it from infecting your device.

Features of ViperSoftX malware

ViperSoftX is a malware that stands out for its innovative arrival and execution techniques, enhanced encryption and malicious extension for web browsers. VipersoftX is a malware that steals information from infected computers.

What is ViperSoftX and how does it work?

ViperSoftX is a type of malware called infostealer, which means it is designed to steal the data from a device. It was first discovered in 2020 by Fortinet1, and has since evolved to become more sophisticated and stealthy.

ViperSoftX mainly targets the users of Chrome and other browsers, such as Firefox, Opera, Brave and Microsoft Edge. It installs a malicious extension called VenomSoftX on the browser, which can access and extract sensitive information such as browser login data, cryptocurrency wallets, stored credit card information, passwords and more2.

It is a JavaScript-based Remote Access Trojan (RAT) that allows attackers to remotely control the compromised machine and execute various malicious actions. VipersoftX uses advanced obfuscation techniques to hide itself and evade detection from security software, It uses 8 layers of code obfuscation before executing its actual payload. It uses 3 types of obfuscation techniques: AES decryption, character array conversion, and UTF-81 decoding,

It establishes its persistence by copying itself to %APPDATA% and creating a shortcut in the startup directory to invoke it. It uses seemingly legitimate names to disguise itself, such as v pn_port.dll, reg.converter.sys, install.sig, and install.db

The main features of the malware

These features make ViperSoftX malware a serious threat to the security of users and organizations that use cryptocurrencies or password managers.

Arrival technique by cracked software: The malware usually poses as a cracked software, an activator or a key generator, which hides the malicious code in the overlay. The malware uses non-malicious files as carriers of the malicious code, such as gup.exe from Notepad++, firefox.exe from Tor or ErrorReportClient.exe from Magix. These files are accompanied by a DLL file that serves as a decryptor and loader of the malicious code. This technique aims to deceive users who are looking for illegal versions of software and to avoid detection by security solutions.
Enhanced encryption by byte remapping: The malware uses a sophisticated encryption method that consists of remapping the bytes of the malicious code according to a specific byte map. Without the correct byte map, the encrypted malicious code, including all components and relevant data, cannot be correctly decrypted, making the decryption and analysis of the code longer and more difficult for analysts. The malware also changes its byte map every month, which makes it even harder to track the malicious code.
Monthly change of command and control server: The malware communicates with a command and control (C&C) server to send the stolen information and receive instructions. The C&C server also changes every month, according to a predictable algorithm based on the current date. The C&C server uses the HTTPS protocol to encrypt the communication with the malware.
Ability to steal data from various cryptocurrency wallets and web browsers: The malware mainly aims to steal data related to cryptocurrencies, such as private keys, passwords and addresses of wallets. The malware targets more than 20 different cryptocurrency wallets, such as Blockchain, Binance, Coinbase, MetaMask or Ledger Live. The malware also installs a malicious extension named VenomSoftX on Chrome, Brave, Edge, Opera and Firefox web browsers. This extension can intercept and modify cryptocurrency transactions made on web browsers. The malware can also steal other sensitive data stored on web browsers, such as cookies, history, bookmarks or autofill data.
Detection of two password managers, KeePass 2 and 1Password: The malware checks for files associated with two popular password managers, KeePass 2 and 1Password, on the infected computer. It also tries to steal data stored in the browser extensions of these password managers. It is not clear whether the malware exploits a known vulnerability of the password managers or whether it uses another method to access the saved passwords.

Consequences of information theft by ViperSoftX malware

ViperSoftX is a malware that can cause serious damage to the users and organizations whose data it steals. The consequences of information theft by ViperSoftX malware can include:

Loss of money: The malware can steal data related to cryptocurrencies, such as private keys, passwords and addresses of wallets. This can result in the loss of funds stored in these wallets, or the redirection of transactions to the attacker’s accounts. The malware can also steal data related to online banking, credit cards or other payment methods, which can enable the attacker to make fraudulent purchases or transfers using the victim’s identity.
Loss of identity or confidentiality: The malware can steal data related to personal or professional identity, such as passport numbers, driver’s license numbers, social security numbers, medical records, online subscriptions, etc. This can result in identity theft, where the attacker can use the victim’s identity to access secure accounts, set up credit cards, apply for loans, or commit other crimes. The malware can also steal data related to confidential or proprietary information, such as software code, algorithms, processes or technologies. This can result in the loss of intellectual property, competitive advantage or trade secrets.
Risks for the consumer and enterprise sectors: The malware targets both individual users and organizations that use cryptocurrencies or password managers. For individual users, the malware can compromise their privacy and security, as well as expose them to financial losses or legal liabilities. For organizations, the malware can compromise their reputation and customer trust, as well as expose them to lawsuits, ransomware demands, recovery costs, regulatory fines or penalties

Victims of the ViperSoftX malware and statistics

The ViperSoftX malware has made many victims around the world, especially in France. Some users have lost large amounts of cryptocurrencies due to the theft of their wallet addresses. Others have seen their online accounts hacked due to the theft of their passwords. Here are some testimonies collected from forums or social networks:

“I was infected by ViperSoftX two weeks ago. I only realized it when I wanted to make a transfer of bitcoins to another wallet. The address I had copied had been replaced by another one in the clipboard. I lost 0.5 bitcoin, which is about 20,000 euros.”
“I got caught by ViperSoftX by downloading a cracked software from a torrent site. The malware installed a malicious extension on my Firefox browser and stole my passwords stored in KeePass. I had to change all my passwords and disinfect my computer with an antivirus.”
“ViperSoftX caused me a lot of problems. The malware accessed my personal and professional data by going through the extension of 1Password on Chrome. It used my Gmail account to send spam to my contacts and my PayPal account to make fraudulent purchases.”

According to TrendMicro, the ViperSoftX malware has infected more than 10,000 computers worldwide since its appearance in 2020. The number of victims could be even higher, as the malware is difficult to detect by antivirus.

How does ViperSoftX spread?

The malware also checks if the device has virtual password managers installed, such as 1Password or KeePass 2. These are applications that help users store and manage their passwords securely. ViperSoftX exploits a vulnerability called CVE-2023-24055 to access the data stored by these password managers through their browser extensions ³.

ViperSoftX also steals users’ cryptocurrency by attacking wallets and exchanges. It targets the following wallets in particular: Armory, Atomic Wallet, Binance, Bitcoin, Blockstream Green, Coinomi, Delta, Electrum, Exodus, Guarda, Jaxx Liberty, Ledger Live, Trezor Bridge, Coin98, Coinbase and MetaMask.

ViperSoftX is a very stealthy malware that can evade antivirus detection by using various techniques. It also checks if the device has security software installed, such as Windows Defender or ESET, and activates its camouflage mechanisms accordingly ⁴.

How to secure your passwords and cryptocurrencies with modern authentication methods?

One of the best ways to protect your passwords and cryptocurrencies from ViperSoftX and other malware is to use modern authentication methods that rely on hardware devices instead of software. These devices are called hardware password managers or cold wallets.

Hardware password manager

A hardware password manager is a device that stores and manages your passwords securely. Unlike a virtual password manager, which runs on your computer or smartphone, a hardware password manager is a separate device that you can carry with you. This way, you can avoid storing your passwords on potentially compromised devices or online services.

A hardware password manager generates and stores strong passwords for your online accounts, which you can access with one master password. To log in to an online service, you can either type the password manually or use the NFC feature of the device to transmit the password to your computer or smartphone.

NFC

NFC (Near Field Communication) is a wireless technology that allows devices to communicate over short distances. You can use NFC for various purposes, such as contactless payments, smart cards, and authentication. By using NFC, you can log in to your online accounts with a simple tap of your hardware password manager on your device.

Some of the benefits of using NFC are:

It is fast and convenient: you do not need to type long passwords or scan QR codes.
It is secure: NFC uses encryption and authentication protocols to prevent eavesdropping or tampering.
It is compatible: NFC works with most:

Cold wallet

A cold wallet is a device that stores your cryptocurrencies offline. Unlike a hot wallet, which is connected to the internet and vulnerable to hacking, a cold wallet is isolated and protected from unauthorized access. To use a cold wallet, you need to transfer your cryptocurrencies from an online platform to the device and vice versa.

A cold wallet generates and stores private keys for your cryptocurrency accounts. A private key is a secret code that allows you to access and control your cryptocurrency funds. You should never share or lose your private key, as it is the only way to access your funds.

Some of the advantages of using a cold wallet are:

It is safe and reliable: you do not have to worry about hackers, malware, or phishing attacks.
It is easy and convenient: you can manage your funds with a simple interface and a few clicks.
It is versatile and compatible: you can store different types of cryptocurrencies on the same device.

One example of a cold wallet that uses NFC technology is the NFC Cold Wallet with EviVault technology from Freemindtronic Andorra. This device allows you to store and manage your cryptocurrencies securely and conveniently with your smartphone.

EviVault Cold Wallet & Hardware Wallet

EviVault is a patented technology that enhances the security and performance of NFC devices. It uses a combination of hardware and software features to protect your data from physical and logical attacks.

Some of the features of EviVault are:

It encrypts and authenticates your data with AES-256 and HMAC-SHA256 algorithms.
It prevents cloning, tampering, or replay attacks with anti-counterfeiting and anti-replay mechanisms.
It detects and blocks brute force attacks with auto unpairing functions traced in a black box.
It optimizes the speed and reliability of NFC communication with error correction and data compression techniques.

With EviVault, you can enjoy the benefits of NFC technology without compromising your security or privacy.

The impact of the ViperSoftX malware on businesses

The ViperSoftX malware does not only target individuals, but also businesses. Indeed, the malware can compromise the security of professional data by stealing the passwords of employees or customers. It can also infect the computer network of the company and spread other malware, such as ransomware or cryptominers.

To protect themselves from the ViperSoftX malware, businesses must take several measures:

Educate employees about the risks associated with downloading software or documents from unofficial or illegal sources.
Use up-to-date and effective antivirus software to detect and remove the malware.
Choose secure and reliable password managers, which do not store sensitive data in browser extensions.
Check regularly the transactions in cryptocurrencies and the addresses of the wallets.

In conclusion

ViperSoftX is a dangerous malware that can steal your passwords and cryptocurrencies from your virtual password managers and online platforms. To protect yourself from ViperSoftX, you should be careful about what you download and install on your device, keep your software updated and secure, avoid installing unknown or suspicious extensions and backup your data regularly.

To secure your passwords and cryptocurrencies with modern authentication methods, you can use hardware password managers or cold wallets that rely on hardware devices instead of software. These devices use NFC technology to offer you a high level of security and convenience for your online accounts. However, you should also follow some best practices, such as keeping your devices updated and secure, using strong passwords and two-factor authentication, and storing only small amounts of cryptocurrency on online platforms.

Juice Jacking: How to Avoid This Cyberattack

Do you often use public USB chargers to recharge your smartphone or tablet? If so, you may be exposing your device to a cyberattack called Juice Jacking. This is a type of attack that can steal your data or infect your device when you use a public USB charger. In this article, we will explain what Juice Jacking is and how to protect yourself from it.

What is Juice Jacking?

Juice Jacking is an attack that hackers can perform. They put malware on the public charger’s USB port. When you plug your device into the charger, the malware can access your data or infect your device.

Juice Jacking can take two forms:

Data theft: the malware can copy your contacts, photos, messages, passwords or any other sensitive information stored on your device.
Malware installation: the malware can install a program that will do malicious things to your device.

The Lack of Awareness and Protection of Juice Jacking Among Users Worldwide

One of the reasons why juice jacking is a serious threat is that many people are unaware of it or do not take precautions when using public USB ports. According to a 2019 study by the University of Illinois at Urbana-Champaign, 64% of Americans use public USB ports to charge their devices, and 15% of them do not know what juice jacking is. The study also found that only 8% of the participants used a USB data blocker or a power-only cable to protect their devices from potential attacks. A similar situation exists in other countries, such as the United Kingdom and Australia. A 2020 study by Comparitech surveyed more than 2,000 people in the UK and found that 45% of them used public USB ports to charge their devices, and 50% of them had never heard of juice jacking. A 2019 study by Finder analyzed the behavior of more than 1,000 people in Australia and found that 41% of them used public USB ports at least once a month, and 21% of them did not know what juice jacking was. These studies show that there is a need for more education and awareness on the risks and prevention of juice jacking.

How to prevent Juice Jacking?

To prevent Juice Jacking, don’t use public USB chargers. Instead, you can use your own charger or a portable battery. However, if you have no choice but to use a public charger, you can take some precautions:

Use a USB data blocker. This is a device that blocks the data transfer between the charger and your device. It only allows the power to pass through.
Turn off your device before plugging it into the charger. This may reduce the risk of data theft or infection.
Use a VPN app on your device. This can encrypt your data and make it harder for hackers to access it.

A more technical explanation by ethical hackers

The Juice Jacking is a cyberattack that exploits the vulnerability of the USB ports that are used for both charging and data transfer. Ethical hackers, who are security professionals who use their skills for good, have demonstrated how this attack works and how to prevent it.

One of the first demonstrations of Juice Jacking was made by researchers from the University of Michigan in 2011 at the DEF CON hacker convention. They set up an informative kiosk on Juice Jacking to raise awareness among visitors about the danger of plugging their devices into public charging stations. When a visitor plugged in their phone, the screen turned red and displayed a warning message: “You should not trust public kiosks with your smart phoneYou should not trust public kiosks with your smart phone You should not trust public kiosks with your smart phone”.

The researchers also showed how malicious actors could use the kiosk to steal data, track devices, or compromise them. They also provided information on how to compromise charging kiosks.

Another demonstration was made by security researchersecurity researcher Kyle Osborn in 2012. He published an attack framework called P2P-ADB that uses a USB On-The-Go cable to connect an attacker’s phone to a victim’s device. The framework includes examples and proofs of concept that would allow hackers to unlock locked phones, steal data from a phone, including authentication keys that would allow the attacker to access the owner’s Google account.

In 2013, security researchers from Georgia Tech published a proof of concept of a malicious tool called Mactans that uses the USB charging port of an Apple mobile device. They used low-cost hardware components to build a small malicious wall charger that can inject malware into an iPhone running

In 2014, security researchers Karsten Nohl and Jakob Lell from srlabs published their research on the BadUSB attack at the Black Hat USA conference . They showed how hackers can reprogram USB devices such as flash drives or cables to act as keyboards or network cards and send commands or data to a connected device.

These demonstrations show how Juice Jacking can be performed by skilled hackers who have access to the USB ports or cables in public places. They also show how users can protect themselves by using their own chargers or batteries, using data blockers, turning off their devices, or using VPN apps.

Some examples and testimonials

Juice Jacking is a serious threat for users of public USB chargers. It can compromise your data and your device’s security. Here are some examples and testimonials that illustrate the risks of Juice Jacking:

In 2011, at the DEF CON hacker convention, an informative kiosk on Juice Jacking was set up to raise awareness among visitors about the danger of plugging their devices into public charging stations . When a visitor plugged in their phone, the screen turned red and displayed a warning message: “You should not trust public kiosks with your smart phone” .
In 2013, security researchers from Georgia Tech presented a proof of concept of a malicious wall charger that could inject malware into an iPhone running the latest version of iOS while it was being charged. The malware bypasses all the built-in security measures in iOS and hides itself in the same way that Apple hides background processes in iOS .
In 2019, the Los Angeles County District Attorney warned travelers about Juice Jacking in airports. He advised travelers to use electrical outlets rather than USB ports to charge their devices.
In 2020, a French journalist testified that she was a victim of Juice Jacking during a trip to India. She said that her phone was infected by malware after plugging it into a USB port in a hotel. The malware sent her messages asking her to pay a ransom to get her data back.

To illustrate the phenomenon of Juice Jacking further, you can also check out these videos:

A video explanation from ZDNet that presents Juice Jacking and its consequences.
A video demonstration from ETX Studio that shows how to protect yourself from Juice Jacking with a USB data blocker.
A video information from Slate that explains why you should not be afraid of Juice Jacking and how it is unlikely to happen.

Some scientific and statistical sources

Juice Jacking is a topic that interests security researchers and public authorities. Here are some scientific and statistical sources that address Juice Jacking:

An academic paper published in 2011 by researchers from the University of Michigan that analyzes the risks associated with using public USB ports and proposes solutions to reduce them.
A technical report published in 2014 by researchers from Johns Hopkins University that describes a method to detect and prevent Juice Jacking on Android devices.
A study conducted in 2017 by Kaspersky Lab that reveals that 25% of French users have already used a public USB charger and that 12% of them have already suffered a loss or theft of data as a result of such use.

Conclusion

Juice Jacking is a cyberattack that targets users of public USB chargers. It can compromise your data and your device’s security. To avoid it, you should use your own charger or battery whenever possible. If you have to use a public charger, you should use a USB data blocker, turn off your device, or use a VPN app.

We hope this article helped you understand what Juice Jacking is and how to protect yourself from it.

How to create strong passwords in the era of quantum computing?

Quantum computing is a technology that promises to revolutionize the field of computation by exploiting the properties of subatomic particles. It offers unprecedented possibilities for scientific research, artificial intelligence or cryptography. But it also represents a risk for the security of data and online communications. Indeed, quantum computers could be able to crack the secret codes that protect our passwords, our bank accounts or our private messages.

What is quantum computing? What is encryption? What is a brute force attack?How to protect ourselves from this threat? The answer is simple: create strong passwords and resist quantum attacks. But what is a strong password? And how to choose it? Here are some tips to help you strengthen your digital security in the era of quantum computing.

What is quantum computing and how does it work in video?

What is a strong password?

A strong password is a password that is hard to guess or crack by a hacker. It must be composed of at least 12 characters, mix uppercase and lowercase letters, numbers and symbols, and not contain dictionary words, proper names or personal data. For example, “P@ssw0rd123” is not a strong password, because it is too short, too simple and too common. On the other hand, “Qx7!tZ9#rGm4” is a strong password, because it is long, complex and random.

Why is a strong password important?

A strong password is important because it reduces the risk that your account will be hacked by a brute force attack. A brute force attack consists of testing all possible combinations of characters until finding the right password. The longer and more complex the password, the more possible combinations there are, and the more time and resources it takes to crack it.

For example, a password of 8 characters composed only of lowercase letters has about 200 billion (26^8) possible combinations. A classical computer can crack it in a few minutes. But a password of 20 characters composed of letters, numbers and symbols has about 10^39 (95^20) possible combinations. A classical computer would need 766 trillion years to crack it.

But what about quantum computers?

Quantum computers are able to perform calculations much faster and more powerful than classical computers thanks to their ability to manipulate qubits instead of bits. A qubit can take two states simultaneously (0 and 1), which allows it to explore multiple solutions at the same time. Thus, a quantum computer could theoretically crack a password by testing all possible combinations in parallel.

However, there are technical and practical limits to this ability. First, you need to have a quantum computer powerful and stable enough to perform this type of operation. However, current quantum computers are still very rudimentary and only have a limited number of qubits. Second, you need to know the type of encryption used to protect the password. However, there are encryption algorithms that are resistant to quantum attacks, such as symmetric encryption or elliptic curve encryption. Third, you need to have access to the system that stores the password. However, there are security measures that prevent unauthorized access, such as two-factor authentication or account locking after several unsuccessful attempts.

Thus, even if quantum computers represent a potential threat for the security of passwords, they are not yet able to crack them easily. Nevertheless, it is prudent to prepare for the advent of this technology by creating strong passwords and changing them regularly.

How to choose a strong password?

To choose a strong password, there are several methods. Here are some examples:

The Diceware method: it consists of randomly choosing several words from a predefined list and separating them by spaces or symbols. For example, “piano cat star 7 &”. This method allows you to create passwords that are easy to remember and hard to crack.
The XKCD method: it consists of choosing four random words and assembling them without space. For example, “correcthorsebatterystaple”. This method is inspired by a comic from the XKCD site that shows that this type of password is safer than a complex but short password.

The random generator method: it consists of using an online tool that creates a random password composed of letters, numbers and symbols. For example, “Qx7!tZ9#rGm4”. This is the method implemented in the evicore nfc and evicore hsm technology from Freemindtronic, which features a random password generator with Shannon entropy control. This technology also automatically calculates the number of bits of the generated password based on the type of printable ASCII 95 characters used. This method allows you to create very secure passwords but difficult or impossible to remember, which requires the use of a hardware or virtual password manager. Whatever the method chosen, it is important to follow some rules:

Do not use the same password for multiple accounts or services.
Do not write the password on a paper or store it on an insecure device.
Do not share the password with other people or communicate it by email or phone.
Do not use obvious clues or security questions to recover the password in case of forgetfulness.
Use a password manager to store and manage your passwords securely.

Tools for creating and protecting strong passwords

If you want to create and protect strong passwords in the age of quantum computing, you can use some of these online tools to help you:

Online password generator: A tool that creates a random and strong password composed of letters, numbers and symbols. For example, Mot de passe.xyz is a free and secure online password generator that lets you choose the length and types of characters for your password.
Password strength calculator: A tool that calculates the entropy (the number of bits) of a password based on its length and the number of possible characters. For example, Password Entropy Calculator is a free online tool that shows you how strong your password is and how long it would take to crack it.
Data breach checker: A tool that checks if your email or phone number has been exposed in a data breach. For example, Have I Been Pwned? is a free online service that lets you check if your personal information has been compromised by hackers.

Using these tools can help you create and protect strong passwords that are resistant to quantum attacks. However, you should also remember to use different passwords for different accounts, change them regularly, and use a password manager to store them safely.

In conclusion

Passwords are essential to protect our privacy and our data online. Faced with the potential threat of quantum computers, it is important to create strong passwords and resist quantum attacks. To do this, we need to choose passwords that are long and complex, change them regularly and manage them with caution. Thus, we will be able to enjoy the benefits of quantum computing without fearing for our digital security.

AMOS Malware Protection with Keepser Cold Wallet

The Threat of AMOS Malware on macOS

AMOS malware is a growing threat to macOS users. Hackers are marketing a new malware for the macOS operating system. Named Atomic Macos Stealer or AMOS, this malicious software is designed to steal user data for $1,000 per month. It extracts passwords from the keychain, steals files on disks, cookies, as well as cards and identification information stored in the browser and tries to extract data from 50 different cryptocurrency wallets. Buyers also benefit from a complete web dashboard to brute force MetaMask.

How AMOS Malware Works

AMOS is capable of accessing iCloud keychain passwords, system information, files from the desktop and documents folder, as well as the Mac password. It is able to infiltrate applications such as Chrome and Firefox and extract autofill information, passwords, cookies, wallets and credit card information. Cryptocurrency wallets such as Electrum, Binance and Atomic are specific targets.

The malware is being propagated using an unsigned disk image file called Setup.dmg. Once executed, the file prompts the victim to enter their system password on a bogus prompt. This allows the malware to escalate privileges and carry out its malicious activities. This technique is similar to that used by other macOS malware, such as MacStealer.

How to Protect Against AMOS Malware

The increase in the deployment of macOS stealer malware by non-state actors highlights the need for users to be cautious when downloading and installing software. The cybersecurity industry recommends that users only download and install software from trustworthy sources, enable two-factor authentication, review app permissions, and refrain from opening suspicious links received via email or SMS messages.

The Solution: Keepser Cold Wallet with EviVault Technology

However, there is a solution to protect your sensitive data against AMOS malware. For only €387, you can purchase two NFC Cold Wallet Keepser from Keepser Group with EviVault technology from Freemindtronic SL. These wallets allow you to store offline and physically externalized from macOS and/or PC computers the private keys and/or seed phrases of cryptocurrency wallets as well as identifier and password pairs. Thus, it will simply be impossible to extract sensitive data from a computer that is not physically present in these computers, even for this AMOS malware.

By using EviVault NFC Cold Wallet technologies from Freemindtronic embedded in Keepser products, you can protect your sensitive data against malware attacks such as AMOS or Cryptbot. These wallets also work on macOS, providing additional protection to Mac users.

The Benefits of EviVault Technology

Thanks to EviVault technology developed by Freemindtronic, the Keepser Cold Wallet is a unique ultra-secure cold storage solution for cryptocurrency wallets, offering anonymous, offline and contactless use via NFC technology, as well as compatibility with NFC Android phones and computer systems via a browser extension.

It’s like they say: “Why pay €1,000 per month to steal sensitive data when you can pay €387 one shot for AMOS malware protection without subscription to protect against it (and other malware like Cryptbot)!” 😉

It is important to take seriously the threats posed by malware such as AMOS and to take the necessary measures to protect your sensitive data. By using advanced technologies such as EviVault NFC Cold Wallet from Freemindtronic embedded in Keepser products, you can ensure that your data is secure.

Through this legal action, Google sought to reduce the number of victims who fall prey to CryptBot’s theft of sensitive information. This court decision is a crucial step in the fight against sophisticated and difficult-to-detect malware attacks such as CryptBot.

In the next section, we will delve deeper into CryptBot and its inner workings

Malware Targeting Chrome Users: Understanding the Inner Workings of CryptBot

CryptBot is a type of malware that targets Chrome users by stealing their personal data, including cryptocurrency. But how does this malware infiltrate Chrome and avoid detection by antivirus software, and how does it communicate with its command server? Below is a brief technical explanation of CryptBot for those interested in the details:

CryptBot is primarily spread through phishing campaigns that offer a fake Chrome update or other legitimate software that contains a hidden virus. Once installed, the virus creates four files in the %TEMP% folder and activates a disguised BAT file that injects CryptBot into Chrome’s legitimate process. This allows the malware to access and encrypt the user’s data using the AES algorithm before sending it to its command server via an HTTP POST request.
In addition to stealing data, CryptBot can receive instructions from the command server via a JSON and AES-based communication protocol. These instructions can include downloading additional malware, updating the configuration settings, or deleting itself as needed.
Although CryptBot is a dangerous form of malware, understanding how it works can help users protect themselves from future attacks.

In conclusion, the threat CryptBot poses to the security of your data and cryptocurrencies on Chrome is real, but there are steps you can take to protect yourself. By following the advice we have shared and using Freemindtronic’s EviVault technology embedded in cold wallets such as Keepser, you can strengthen the security of your computer and protect your cryptographic assets from hackers.

What is a wood transistor?

A transistor is a device that can amplify or switch electrical signals. Transistors are the building blocks of modern electronics, such as computers, smartphones, and sensors. They are usually made of silicon, a semiconductor material that can conduct electricity under certain conditions.

However, a wood transistor is a type of transistor that uses wood as the base material instead of silicon. Wood is also a semiconductor, but with different properties than silicon. To make wood transistors, researchers coat thin slices of wood with carbon nanotubes. These are tiny tubes of carbon atoms that have excellent electrical and mechanical properties.

The carbon nanotubes act as electrodes, which are the parts of the transistor that connect to the external circuit. The wood acts as the channel, which is the part of the transistor that controls the flow of current between the electrodes.

How does a wood transistor work?

A wood transistor works by applying a voltage to one of the electrodes, called the gate. This voltage creates an electric field that affects the conductivity of the wood channel. By changing the gate voltage, the current flowing between the other two electrodes, called the source and the drain, can be modulated.

The wood transistor can operate in two modes: depletion mode and enhancement mode. In depletion mode, the wood channel is normally conductive, and the gate voltage can reduce or stop the current flow. In enhancement mode, the wood channel is normally non-conductive, and the gate voltage can increase or start the current flow.

The researchers who developed the wood transistor made an interesting discovery. They found that it can switch between depletion mode and enhancement mode by changing the polarity of the gate voltage. This means that the wood transistor can perform both n-type and p-type functions, which are essential for creating complex electronic circuits.

Why is a wood transistor important?

A wood transistor is important because it offers several advantages over conventional silicon transistors. Some of these advantages are:

Wood is abundant, cheap, biodegradable, and renewable, which makes it an environmentally friendly alternative to silicon. Silicon is scarce, expensive, non-biodegradable, and requires high-energy processing.
Wood transistors have a low operating voltage, which means they consume less power and generate less heat than silicon transistors. This can improve the energy efficiency and performance of electronic devices.
Wood transistors have a high sensitivity to humidity and temperature changes, which makes them suitable for applications such as environmental sensors and smart textiles.
Moreover, wood transistors have a flexible and transparent structure, which makes them compatible with flexible and wearable electronics.

What are the challenges and opportunities for wood transistors?

Researchers are still developing wood transistors, and they face some challenges and opportunities for further improvement. Some of these are:

The stability and reliability of wood transistors need to be enhanced by optimizing the fabrication process and protecting them from moisture and oxidation.
The scalability and integration of wood transistors need to be improved by developing methods to produce large-area and high-density arrays of wood transistors on various substrates.
The functionality and diversity of wood transistors need to be expanded by exploring different types of wood materials and carbon nanotube coatings with different properties.
The applications and markets for wood transistors need to be explored by collaborating with industry partners and end-users who can benefit from this novel technology.

Conclusion

Wood transistors are a breakthrough innovation that can revolutionize green electronics. They combine the natural advantages of wood with the exceptional properties of carbon nanotubes to create low-power, high-performance, flexible, transparent, and biodegradable electronic devices.
