T1552.006 — Unsecured Credentials: Group Policy Preferences
Sub-technique of T1552 Unsecured Credentials
Description
Adversaries may attempt to find unsecured credentials in Group Policy Preferences (GPP). GPP are tools that allow administrators to create domain policies with embedded credentials. These policies allow administrators to set local accounts.
These group policies are stored in SYSVOL on a domain controller. This means that any domain user can view the SYSVOL share and decrypt the password (using the AES key that has been made public).
The following tools and scripts can be used to gather and decrypt the password file from Group Policy Preference XML files:
* Metasploit’s post exploitation module: post/windows/gather/credentials/gpp
* Get-GPPPassword
* gpprefdecrypt.py
On the SYSVOL share, adversaries may use the following command to enumerate potential GPP XML files: dir /s * .xml

This project's own SigmaHQ-derived detection pipeline tags every compiled rule with the ATT&CK technique(s) it maps to -- if a rule in your install covers this technique, it shows up automatically on your own Grafana Alerts dashboard's "Top ATT&CK Techniques" panel, no lookup needed. This page exists so a click from there always lands here on easysiem.com, not on attack.mitre.org.
