This rule detects when a cron job is created or modified via a remote SSH session. It specifically looks for the string "crontab -e" within TCP traffic destined for port 22 (SSH), indicating an interactive session where a user is editing their crontab file. This activity, when originating from a remote SSH session, could be indicative of an attacker establishing persistence or scheduling malicious tasks on a compromised system.
