Keiten is a known malware family referenced as part of the SSHStalker Linux botnet toolkit. In the observed SSHStalker operation, Keiten was used alongside Tsunami, multiple C-based IRC bots, and Perl scripts within an IRC-centric command-and-control architecture. The broader campaign targeted Linux servers through mass SSH scanning and brute-force attacks, then staged and compiled payloads directly on compromised hosts, maintained persistence through cron-based relaunch mechanisms, and used log-cleaning components and rootkit-like artifacts. Researchers observed the operation affecting large numbers of internet-facing Linux systems, especially cloud-hosted servers with strong links to Oracle Cloud infrastructure. The tradecraft resembled Outlaw/Maxlas-style Linux botnets, though attribution was not confirmed; Romanian-language artifacts were noted in the wider SSHStalker ecosystem. Within the provided content, Keiten is specifically identified only as one of the malware families used by SSHStalker, and no additional high-confidence family-specific capabilities, infection vectors, or indicators unique to Keiten are directly provided.
