This activity is often associated with attackers performing reconnaissance after gaining initial access to a compromised system. By querying Group Policy Objects (GPOs), adversaries can map out the Active Directory environment, discover potential attack paths, and identify opportunities for privilege escalation or lateral movement. The rule is designed to detect this behavior across various Windows environments, using data from Elastic Endgame, Elastic Defend, Windows Security Event Logs, Microsoft Defender XDR, Sysmon, SentinelOne, and Crowdstrike.
