Winning the Game of Active Directory

Brandon Colley

Walks through attack paths in the Game of Active Directory lab environment and demonstrates practical misconfiguration mitigations.

Summary

The Game of Active Directory Environment

Game of Active Directory (GOAD) is a vulnerable lab environment designed for penetration testers to practice domain exploitation techniques. It contains over thirty distinct attack vectors demonstrating paths to full domain compromise.

Exploiting Common AD Misconfigurations

Penetration testers navigate complex Active Directory networks by chaining misconfigured permissions, weak credential handling, and default domain policies. Exploiting these flaws allows rapid lateral movement and domain privilege escalation.

Implementing Robust Mitigations

Securing Active Directory environments requires addressing underlying misconfigurations rather than relying solely on detection. Implementing credential hygiene, fine-grained access controls, and least-privilege delegation effectively neutralizes common attack chains.

Practical Hardening Strategies

Defenders validate security posture by verifying that deployed configuration changes successfully block known exploitation paths across domain controllers and joined workstations.
