Cross-platform Chaos malware
A new Botnet is taking hold of Windows and Linux devices alike, using them to start DDoS (Distributed Denial of Service) attacks. Chaos, a Go-based malware, can infect various architectures like x86, AMD64, ARMv5 and many more. With such a wide spectrum, it does not just target high value devices, it also targets smaller ones. The malware mainly focuses on unpatched devices, but also tries to hijack other devices with brute forcing or stolen SSH keys. After infecting one, it creates a backdoor for itself to be able to communicate with their C2-Server (Command and Control).
Researchers from the Black Lotus Labs were able to identify targets of the Chaos clusters. They cover a broad range targeting gaming to financial services, media and entertainment industry as well as their competitors, DDoS-as-a-service providers.
