Domain Group Discovery With Wmic
This analytic looks for the execution of
wmic.exe with command-line arguments utilized to query for domain groups. The arguments utilized in this command return a list of all domain groups. Red Teams and adversaries alike use wmic.exe to enumerate domain groups for situational awareness and Active Directory Discovery.
