The following analytic detects the execution of the Get-ForestDomain cmdlet, a component of the PowerView toolkit used for Windows domain enumeration. It leverages PowerShell Script Block Logging (EventCode=4104) to identify this activity. Detecting Get-ForestDomain is significant because adversaries and Red Teams use it to gather detailed information about Active Directory forest and domain configurations. If confirmed malicious, this activity could enable attackers to understand the domain structure, facilitating lateral movement or privilege escalation within the environment.

How To Implement

The following Hunting analytic requires PowerShell operational logs to be imported. Modify the powershell macro as needed to match the sourcetype or add index. This analytic is specific to 4104, or PowerShell Script Block Logging.

Known False Positives

Administrators may leverage PowerSploit tools for legitimate reasons, filter as needed.
