Could Your Device Be Caught in the Matrix Cyber Attack?

 



A recent report has outlined a large-scale cyberattack widely referred to as the Matrix campaign. This attack has put in jeopardy an estimated 35 million internet-connected devices across the globe. "This attack contributes to slowing down internet connections to homes and exposes businesses to data breaches, operational interruptions, and reputational damage among others," said Aqua Security's threat intelligence team.

The Matrix campaign is a threat that has been orchestrated by an actor called Matrix. The attack leverages vulnerabilities and weak security practices in the devices like home routers, surveillance cameras, and enterprise systems. According to experts, this attack signifies an emerging trend of IoT device and enterprise infrastructure targeting in order to build botnets for DDoS attacks.


How the Matrix Attack Works

They take advantage of the openly available hacking tools, poor passwords, and misconfiguration to enter devices. Methods used are brute-force attacks and exploitation of hardcoded default credentials such as "admin:admin" or "root:camera." Once a device is compromised, it joins a botnet—a network of hijacked devices that can be used to carry out large-scale cyber attacks like DDoS, overwhelming targets with traffic.

Matrix is not only targeting the home router but also, for instance, the Telecom equipment and server infrastructure are under attack through common protocols and applications such as Telnet, SSH, and Hadoop. Even software development life cycle servers are vulnerable to attack; it has proven an evolution of cybercrime through the exploitation of corporate vulnerabilities. 


A Cybercrime Evolution: Low Skills, Big Impact

The scariest part of the Matrix attack is that it seems to be the handiwork of a lone, somewhat novice hacker known as a "script kiddie." This attacker, with the aid of widely available AI tools and ready-to-use hacking software, has mounted an unprecedented campaign around the globe.

According to Aqua Security, this attack highlights the ease with which low-skilled hackers can now execute sophisticated attacks, underscoring the growing danger of poorly secured devices.  


How to Protect Yourself

To safeguard your devices from becoming part of a botnet, it is essential to take the following precautions:  

1. Update Firmware: Ensure your router and other devices run the latest software updates.

2. Strengthen Passwords: Replace default credentials with strong, unique passwords. 

3. Secure Access: Where possible, use additional security measures such as two-factor authentication.


Having addressed these vulnerabilities, the users can secure their devices from further attacks. The Matrix campaign reminds everyone that in today's networked world, proper cybersecurity is essential.


A Matrix Update Patches Serious End-to-End Encryption Flaws

Recently the open source Matrix messenger protocol published security warnings on its platform about two critical-severity vulnerabilities that affect the end-to-end encryption in the software development kit (SDK). 

As per the warning statement, the groups of malicious actors are exploiting these vulnerabilities that could break the confidentiality of Matrix communications. The vulnerabilities also allow the threat actors to run man-in-the-middle attacks that expose message contents in a readable form. 

According to the technical data, the users who were using the matrix-js-sdk, matrix-android-sdk2, and matrix-ios-sdk, like Element, Cinny, SchildiChat, Beeper, Circuli, and Synod.im have been hit by the bugs. However, the platform clarified that clients using a different encryption implementation such as Hydrogen, Nheko, ElementX, FluffyChat, Timmy, Syphon, Gomuks, Pantalaimon) are safe from the attacks. 

The vulnerabilities were reported to Matrix by the researchers of Brave Software, the University of Sheffield, and the Royal Holloway University in London. The group published the technical details of the research findings. 

List of the critical severity flaws discovered by the team

 
  • CVE-2022-39255: Same as CVE-2022-39251 but impacting matrix-ios-sdk (iOS clients). 
  • CVE-2022-39251: Protocol-confusion bug in matrix-js-sdk, leading to incorrectly accepting messages from a spoofed sender, possibly impersonating a trusted sender. 

The same flaw makes it possible for malicious home server admins to add backup keys to the target's account. 

  • CVE-2022-39250: Key/Device identifier confusion in SAS verification on matrix-js-sdk, enabling a malicious server administrator to break emoji-based verification when cross-signing is used, authenticating themselves instead of the target user.
  • CVE-2022-39257: Same as CVE-2022-39249 but impacting matrix-ios-sdk (iOS clients).
  • CVE-2022-39248: Same as CVE-2022-39251 but impacting matrix-android-sdk2 (Android clients). 
  • CVE-2022-39249: Semi-trusted impersonation problem in matrix-js-sdk leading to accepting keys forwarded without request, making impersonation of other users in the server possible. Clients mark these messages as suspicious on the recipient's end,  thus dropping the severity of the bug. 
  • CVE-2022-39246: Same as CVE-2022-39249 but impacting matrix-android-sdk2 (Android clients). 
Furthermore, the report detailing listed two problems that are yet to receive an identification number. One of these problems allows malicious actors access to the home server and the second refers to using AES-CTR.
