Ngrok Execution for Tunneling
Detects the execution of Ngrok, a legitimate utility often abused by threat actors for port forwarding and tunneling. This allows them to expose local services to the internet, bypassing firewalls and network restrictions. The rule specifically looks for common command-line arguments used with Ngrok, such as those for tunneling specific TCP ports (e.g., 139, 445, 3389, 5985, 5986), HTTP services, or configuration file usage.
