The following analytic utilizes PowerShell Script Block Logging (EventCode=4104) to identify the execution of the Get-WmiObject commandlet. The DS_Computer class parameter leverages WMI to query for all domain computers. Red Teams and adversaries may leverage this commandlet to enumerate domain computers for situational awareness and Active Directory Discovery.
