Linux security admins must be wary of an emerging and dangerous threat: the cShell DDoS bot malware. Recently discovered by researchers at ASEC, this sophisticated bot uses Go programming language-based code known as cShell to exploit weak passwords and poor security practices in SSH servers running Linux-based operating systems to gain control. Popular Linux utilities like screen and hping3 orchestrate distributed denial-of-service (DDoS) attacks that leverage infected systems to overwhelm their targets with traffic.
