Study Notes
- KmsdBot is a cryptomining botnet that could also be used for denial-of-service (DDOS) attacks.
- Researchers at Akamai Security Research noticed that, when controlling the botnet, its controllers forgot to put a space between an IP address and a port in a command. This caused a panic crash with an "index out of range" error.
- Because there's no persistence, the bot stays down, and malicious agents would need to reinfect a machine and rebuild the bot's functions.
- KmsdBot is an intriguing modern malware written in Golang.
- Almost all KmsdBot activity Akamai's firm was tracking has ceased, though the authors may be trying to reinfect systems again. Using public key authentication for secure shell connections, or at a minimum improving login credentials, is the best defense in the first place.
