# Performing Active Directory Compromise Investigation
## Overview
Active Directory (AD) compromise investigation is a critical incident response capability that focuses on identifying how attackers gained access to domain services, what persistence mechanisms they established, and the scope of credential compromise. Since 88% of breaches involve compromised credentials (Verizon 2025 DBIR), AD is the primary target for enterprise-wide attacks. Investigators must analyze NTDS.dit database integrity, Kerberos ticket-granting activity, Group Policy modifications, replication metadata, and privileged group membership changes to reconstruct the attack chain and determine full compromise scope.
## When to Use
- When conducting security assessments that involve performing active directory compromise investigation
- When following incident response procedures for related security events
- When performing scheduled security testing or auditing activities
- When validating security controls through hands-on testing
