DET0381 Detect Access and Decryption of Group Policy Preference (GPP) Credentials in SYSVOL
AN1075 Analytic 1075
Correlates file enumeration of XML files in the SYSVOL share with suspicious process execution that decodes or reads encrypted credentials embedded in Group Policy Preference files (e.g., Get-GPPPassword.ps1, gpprefdecrypt.py, Metasploit). Detects abnormal access to \DOMAIN\SYSVOL combined with XML file parsing or decryption logic.

Threat actor context
These are explicit actor-to-technique associations in the existing Threat Matrix snapshot, not attribution of an event or proof that a detector identifies the actor. No tool-to-actor relationship is inferred.
