macOS Login Hook Script Modified via SSH
This rule detects modifications to macOS Login Hook scripts via SSH. Login Hooks are scripts that execute when a user logs in or out, and their modification can be an indicator of persistence mechanisms used by attackers. The rule specifically looks for TCP traffic on port 22 (SSH) containing the string 'LoginHook' in a case-insensitive manner, indicating an attempt to interact with or modify these scripts.
