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
