SSHStalker Botnet Activity Detection
This rule detects various indicators associated with the SSHStalker botnet on Linux systems, including outbound IRC-like network connections, modifications to cron files for persistence, log tampering (specifically utmp/wtmp/lastlog files), and the execution of compilers from suspicious directories like /tmp or /dev/shm. Each section of the rule targets a specific behavior of the botnet.
