Matrix Botnet Targets IoT Devices in Massive DDoS Attack

Matrix Linked to Widespread DDoS Campaign Targeting IoT Devices

A newly identified threat actor, known as Matrix, has emerged as a significant player in a widespread distributed denial-of-service (DDoS) campaign. This operation exploits vulnerabilities and misconfigurations in Internet of Things (IoT) devices, transforming them into a potent botnet for disruptive attacks. According to Assaf Morag, director of threat intelligence at cloud security firm Aqua, this campaign exemplifies a "do-it-all-yourself" approach to cyberattacks, highlighting the ease with which individuals can launch sophisticated operations.

The Scope of Matrix’s DDoS Campaign

Evidence suggests that Matrix may be a lone wolf actor, possibly a script kiddie from Russia. The primary targets of this campaign include IP addresses in China and Japan, with additional attacks observed in Argentina, Australia, Brazil, Egypt, India, and the United States. Notably absent from the list of victims is Ukraine, indicating that financial gain rather than geopolitical motives drives this campaign.

Tactics Employed in the Campaign

Matrix’s attacks rely on exploiting known security vulnerabilities and weak or default credentials. The following types of internet-connected devices are especially vulnerable:

• IP cameras
• DVRs
• Routers
• Telecom equipment

Moreover, the threat actor has been seen leveraging misconfigured servers, particularly Telnet, SSH, and Hadoop, with a focus on IP addresses associated with major cloud service providers like Amazon Web Services (AWS), Microsoft Azure, and Google Cloud.

Tools and Malware Used

The malicious activities orchestrated by Matrix utilize a variety of publicly available scripts and tools, many of which can be found on GitHub. Key malware components include:

• Mirai Botnet: A well-known malware used for DDoS attacks.
• PYbot and pynet: Additional tools utilized to enhance attack capabilities.
• DiscordGo: A tool that enables attacks through the Discord platform.
• JavaScript Programs: Specifically designed for HTTP/HTTPS flood attacks.
• Disabling Microsoft Defender: A tool that can neutralize antivirus defenses on Windows machines.

In a notable development, Matrix has created a GitHub account as of November 2023 to distribute DDoS artifacts associated with their campaign. They are also believed to operate a Telegram bot named "Kraken Autobuy," which offers DDoS-for-hire services with various payment tiers in cryptocurrency.

Implications and Recommendations

Morag emphasizes that while the Matrix campaign may not be highly sophisticated, it illustrates how accessible tools and minimal technical knowledge can empower individuals to execute complicated attacks. To defend against such opportunistic attacks, organizations should prioritize:

• Changing default credentials for all devices.
• Securing administrative protocols.
• Regularly applying firmware updates.

Related Threats: XorBot Botnet

The disclosure of the Matrix campaign coincides with reports from NSFOCUS about a new botnet family called XorBot. This botnet has been targeting Intelbras cameras and routers from brands like NETGEAR, TP-Link, and D-Link since November 2023. As the botnet expands, its operators are actively promoting DDoS attack rental services under the name Masjesu, employing advanced techniques to obscure their methods.
