In recent developments, the Matrix botnet has been identified as the driving force behind an extensive distributed denial-of-service (DDoS) campaign. This operation exploits security weaknesses and misconfigurations in Internet of Things (IoT) devices, integrating them into a potent botnet capable of significant disruptions.

Comprehensive Setup

According to Assaf Morag, director of threat intelligence at Aqua, the campaign showcases an all-encompassing approach, from scanning and exploiting vulnerabilities to deploying malware and establishing operational kits.

Perpetrator Profile

Investigations suggest that a solo hacker, potentially a Russian novice in cyber activities, is orchestrating these attacks. Their efforts have predominantly affected IP addresses in China and Japan, with additional hits in Argentina, Australia, Brazil, Egypt, India, and the United States. Notably, the exclusion of Ukrainian targets points to financially driven motives.

Vulnerable Technologies

The attacks exploit known security loopholes and capitalize on the use of weak or default credentials. Targeted devices include internet-connected gadgets like IP cameras, DVRs, routers, and telecom hardware.

Infrastructure Abuse

The campaign also targets misconfigured Telnet, SSH, and Hadoop servers. There is a significant focus on IP ranges linked to cloud service providers such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud.

Deploying Mirai Botnet

The Matrix botnet utilizes various accessible scripts and tools, including those hosted on GitHub, to install Mirai malware and other DDoS software. This toolkit includes PYbot, pynet, and DiscordGo, among others.

Operations on GitHub

Evidence shows that Matrix maintains a GitHub account for hosting parts of their DDoS arsenal, which they initiated in November 2023.

DDoS-for-Hire Service

The campaign is linked to a Telegram bot, "Kraken Autobuy," which facilitates DDoS-for-hire services, allowing clients to purchase attack services with cryptocurrency.

Expert Commentary Morag from Aqua emphasizes the campaign's accessibility, demonstrating how available tools and basic technical know-how can launch widespread attacks on multiple vulnerabilities. He underscores the importance of bolstering security fundamentals, such as updating default passwords and securing administrative access, to combat these types of threats.

Related Observations Parallel to these findings, NSFOCUS has highlighted a new botnet variant known as XorBot, primarily targeting Intelbras cameras and routers from manufacturers like NETGEAR, TP-Link, and D-Link. Since November 2023, this botnet has grown, offering DDoS attack rentals under the brand name Masjesu. The operators have implemented sophisticated techniques like code redundancy and signature obfuscation to enhance their evasion and complicate detection efforts.
