A new Mirai variant, dubbed "Gayfemboy," has been targeting industrial routers, specifically those from the Four-Faith brand, using Distributed Denial-of-Service (DDoS) attacks. The botnet has gained over 15,000 daily active nodes and has launched attacks against researchers tracking it. This emergence highlights the ongoing threat posed by Mirai variants and the importance of vigilance in detecting and responding to cyber threats.
The Gayfemboy botnet is a new Mirai variant targeting industrial routers from Four-Faith brand. The botnet exploits 0-day and N-day vulnerabilities to launch DDoS attacks. The botnet has gained over 15,000 daily active nodes by November 2024. It targets devices such as DVRs, routers, and security appliances using exploits and infection methods. The botnet is particularly active in targeting China, the US, Iran, Russia, and Turkey. Its attacks can launch large-scale traffic attacks instantly using distributed botnets. The botnet employs lax security measures, making it easier for researchers to track its activities.
The cybersecurity landscape has recently witnessed the emergence of a new Mirai variant, dubbed "Gayfemboy," which has been targeting industrial routers, specifically those from the Four-Faith brand. This botnet has been exploiting several vulnerabilities, including 0-day and N-day exploits, to launch Distributed Denial-of-Service (DDoS) attacks against its victims.
According to a report published by QiAnXin XLab experts, the Gayfemboy botnet was first identified in February 2024. It borrows code from the basic Mirai variant but has since integrated new features and exploits, including N-day and 0-day vulnerabilities. By November 2024, the botnet had already gained over 15,000 daily active nodes and had launched DDoS attacks against researchers tracking it.
The Gayfemboy botnet's modus operandi is to exploit vulnerabilities in various devices, including DVRs, routers, and security appliances. It uses a combination of exploits and infection methods to infect its victims, often targeting key identifiers such as device operating systems or other identifying details. The botnet's grouping information typically includes these identifiers, allowing attackers to efficiently manage and control the large botnet.
The Gayfemboy botnet has been particularly active in targeting China, the United States, Iran, Russia, and Turkey. Its attacks have peaked in October and November 2024, with key targets including domains registered for analysis and VPS hosts hosted by cloud providers. The botnet's DDoS attacks can launch large-scale traffic attacks instantly using distributed botnets, malicious tools, or amplification techniques, depleting or disabling the target network's resources.
Despite its evolution, the Gayfemboy botnet still employs lax security measures, such as plaintext strings and unchanged output messages. This lack of sophistication makes it easier for researchers to track and analyze the botnet's activities.
The emergence of the Gayfemboy botnet highlights the ongoing threat posed by Mirai variants and the importance of vigilance in detecting and responding to cyber threats. As the cybersecurity landscape continues to evolve, it is essential for organizations and individuals to stay informed about the latest threats and take proactive measures to protect themselves against such attacks.
In conclusion, the Gayfemboy botnet represents a significant threat to network security, with its ability to launch large-scale DDoS attacks using distributed botnets. As researchers continue to monitor and analyze this threat, it is crucial for individuals and organizations to stay informed about the latest developments in the cybersecurity landscape.
