ZeroLogon vulnerability (CVE-2020-1472) allows Privilege Escalation attack against Microsoft Active Directory domain controllers, making it possible for a hacker to impersonate any computer, including the root domain controller.

The flaw was addressed in Microsoft’s August 2020 security updates. However, the risk went higher when four PoCs were released and published publicly.

Recently, Microsoft warned about multiple malicious activities by MuddyWater using Zerologon vulnerabilitiy in active campaigns over the last 2 weeks.
