WHAT IT DOES

What hydra_bruteforce does on MCP Kali Pentest

WHY IT NEEDS A POLICY

Why hydra_bruteforce needs a policy

This executes external attack operations against target systems, making it Execute category. Severity is critical because misuse can compromise remote systems, violate unauthorized access laws, and cause account lockouts across SSH, RDP, FTP, and HTTP services at scale.
