## What it is
A Python CLI script that tests domain controllers for the ZeroLogon vulnerability (CVE-2020-1472) using the Impacket library. It attempts the Netlogon authentication bypass and stops immediately on success, without performing any further Netlogon operations.

## Use cases
- test if a domain controller is vulnerable to ZeroLogon
- check CVE-2020-1472 on a Windows DC
- detect Netlogon authentication bypass vulnerability
- verify patch status of a domain controller for ZeroLogon
- run ZeroLogon tester from a Docker container

## When to choose
- you need a quick, safe detection script for CVE-2020-1472 that does not exploit beyond the auth bypass
- you want a lightweight Python tool based on Impacket
- you need to audit domain controllers during a penetration test or patch verification

## When to avoid
- you need full exploitation or post-exploitation of ZeroLogon, not just detection
- your target is not a domain controller or backup DC
- you cannot meet the Python 3.7+ requirement or obtain the correct NetBIOS name of the DC
