Gayfemboy Botnet: Evolution of a Potent Threat

The Gayfemboy botnet is a sophisticated Mirai variant that exploits a 0-day vulnerability in Four-Faith industrial routers. Its advanced development includes modifications to registration packets, UPX packing, and exploitation of multiple vulnerabilities. With over 15,000 active nodes, it has launched significant DDoS attacks, peaking at 100GB of traffic. The botnet’s ability to leverage both known and zero-day vulnerabilities highlights critical cybersecurity concerns and the pressing need for robust security measures.
