GPOHound: Offensive GPO dumping and analysis tool

GPOHound is a tool for dumping and analysing Group Policy Objects (GPOs) extracted from the SYSVOL share.

It provides a structured, formalized format to help uncover misconfigurations, insecure settings, and privilege escalation paths in Active Directory environments.

The tool integrates with BloodHound’s Neo4j database, using it as an LDAP-like source for Active Directory information while also enriching it by adding new relationships (edges) and node properties based on the analysis.

Features

•  Dumps GPOs in a structured JSON or tree format

•  Handles multiple domains

•  Resolves GPO names with GPO GUIDs

•  Filters output by GPO files, GPO GUIDs, and domains

•  Searches in key/value pairs using regex

•  Groups settings by impacted object (e.g., Local Groups, Registry)

•  Detects members added to local privileged groups

•  Detects insecure registry settings, stored credentials, and privilege rights

•  Supports decrypting VNC credentials and GPP passwords

•  Finds domains, containers, and OUs affected by GPOs

•  Gets GPOs applied to a specific user, computer, OU, container, or domain

•  Enriches BloodHound data with relationships and properties

Current analysis and enrichment

• Detection of users assigned to privileged local groups during logon

• Detection of renamed built-in privileged local groups.

• Detection of trustees added to privileged local groups using “Preference Process Variables” (e.g., %ComputerName%, %DomainName%)

• Detection of abusable trustees using sAMAccountName hijacking

• Detection of any trustees added to privileged local groups:

  Group	Edge
  Administrators	AdminTo
  Remote Desktop Users	CanRDP
  Distributed COM Users	ExecuteDCOM
  Remote Management Users	CanPSRemote
  Backup Operators	CanPrivEsc
  Print Operators	CanPrivEsc
  Network Configuration Operators	CanPrivEsc

Default privileged trustees, as well as service accounts with SIDs starting with S-1-5-8, are excluded from analysis.
