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.


TP-Link Routers Vulnerable Again; Voids Passwords! Patching Highly Suggested!



A “zero-day vulnerability” was recently discovered in the “TP-Link Archer C5v4 routers” with the firmware version 3.16.0 0.9.1 v600c and of the build 180124 Rel.28919n.

This vulnerability could affect devices both at corporate levels as well as domestic level. The attacker could take control of the routers configuration by way of “telnet on the local area network” and it could connect to the File Transfer Protocol (FTP) via the LAN or WAN (wide area network).

The attackers could gain complete access of all the admin licenses and privileges. Enabling guest wi-fi, and acting an entry point happen to be a few other demerits of the vulnerable router.

Previously as per reports there was a “password overflow issue”. When a string shorter than the estimated length is typed then the estimated length is sent as the password, altering the actual password whereas if too long then the password gets void.

The vulnerability allegedly depends on the type of request that is sent through for requesting access to the device. Either it is safe or is vulnerable. The safe requests for HTML content there are two aspects that need to be taken into account.

One of them being the “TokenID” and the other being “the JSESSIONID”. Per reports the common Gateway Interface though, is only based on the referrer’s HTTP headers if it matches the IP address or the domain related to it then the main service of the routers thinks it to be valid and if the referrer is removed it responds as “Forbidden”.

The automated attacks that were dissipated via the botnet malware, “Mirai” were caused by weak passwords that allowed access to the FTP server and even provided console access.


Reportedly, the function “strncmp” is used to validate the referrer header with the string “tplinkwifi.net”. It apparently also validates for the IP address. This is definitely hence a disconcerting vulnerability which could be easily exploited.

The shorter strings when sent corrupt the password stopping the users from logging in but luckily it would stop the attacker too. FTP, Telnet and other services are mostly affected by this.

A longer string length made it entirely void and the value became empty. This made Telnet and FTP accessible simply by using “admin” as a password which is the default.

The same configuration of FTP is also allowed on the WAN. The router also reportedly happens to be vulnerable to the CGI attack which is pretty injurious to privacy.

So far there isn’t a way to set a new password, but even if there were the next vulnerable LAN/WAN/CGI request would void that password as well. Per reports, another aftermath of this vulnerability is that the RSA encryption key would crash.

This vulnerability is extremely disconcerting when the “Internet of Things” IoT security is considered at large. Millions of businesses and homes could be affected by any exploit or vulnerability these routers disperse.

What could be done right off the bat is, creating stronger passwords, applying two-factor authentication, changing all the default passwords and at last applying mitigating controls to all the devices in use.

Patching is HIGHLY ADVISED. TP-Link has provided patches for the TP-Link Archer C5 v5 and other versions.
