enum4linux_scan · Kali MCP: Risk & Policy

WHAT IT DOES

What enum4linux_scan does on Kali

AI agents invoke enum4linux_scan to trigger actions in Kali. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why enum4linux_scan needs a policy

The tool explicitly executes Enum4linux, an active enumeration tool that probes remote Windows/Samba systems to extract users, shares, policies, and other sensitive information. This is an active operation against external targets (not just a local read), making it Execute.
