Setuid Binary Created on Remote Host via SSH
This rule detects attempts to create a setuid binary on a remote host via an SSH connection. It specifically looks for the string "chmod u+s" within TCP traffic destined for port 22 (SSH), indicating a command to set the setuid bit on a file. This activity is often associated with privilege escalation attempts where an attacker tries to create a backdoor or maintain persistence with elevated privileges.
