Get DomainPolicy with Powershell

The following analytic detects the execution of `powershell.exe` running the `Get-DomainPolicy` cmdlet, which is used to retrieve password policies in a Windows domain. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line executions. This activity is significant as it indicates potential reconnaissance efforts by adversaries to gather domain policy information, which is crucial for planning further attacks. If confirmed malicious, this could lead to unauthorized access to sensitive domain configurations, aiding in privilege escalation and lateral movement within the network.
