Possible AD Groups Or Users Enumeration Via PowerShell - PoshModule (via ps_module)

This rule detects threat actors may attempt to find domain-level groups and permission settings. The knowledge of domain-level permission groups can help threat actors determine which groups exist and which users belong to a particular group. Adversaries may use this information to determine which users have elevated permissions, such as domain administrators.
