The detection rule titled 'Windows PowerSploit GPP Discovery' identifies the execution of the PowerShell cmdlet 'Get-GPPPassword', which is utilized to search for unsecured credentials within Group Policy Preferences (GPP). This rule is significant because it focuses on monitoring PowerShell Script Block Logging (EventCode=4104) for specific attempts to access sensitive stored credentials from the SYSVOL directory. If an attacker successfully uses this command, they can potentially escalate their privileges or maneuver laterally across the network by leveraging exposed credentials. Implementing this analytic necessitates enabling PowerShell Script Block Logging on endpoints to capture the relevant execution details reliably.
