Active Directory Penetration Testing

Reveal hidden privilege paths and domain weaknesses before attackers do.

Overview

Active Directory (AD) is the backbone of identity and access management in most enterprises, controlling user authentication, permissions, and resource access. However, misconfigurations, weak password policies, and overlooked trust relationships can provide attackers with paths to escalate privileges and move laterally across your entire network, potentially taking over your domain.

Our Active Directory Penetration Testing service simulates realistic attack paths to show how these weaknesses translate to business impact, without causing disruption.

Active Directory

Domain Enumeration

Map users, groups, computers, domain trusts, and organizational structure.

Credential Harvesting

Kerberoasting, AS-REP roasting, password spraying, credential extraction.

Delegation Abuse

Exploit unconstrained, constrained, and resource-based delegation for impersonation.

Privilege Escalation

Abuse ACLs/DACLs, nested groups, and writable GPO paths for privilege gain.

Lateral Movement

Pass-the-Hash, Pass-the-Ticket, token impersonation, WinRM/WMI/SMB pivots.

Attack Path Analysis

Map chains from low privilege to domain dominance; validate chokepoints with DCsync or shadow credentials.

Domain Controllers & Trusts

Review cross-domain trusts, replication, and privileged objects exposure.

Configuration Issues

Identify legacy protocols, missing patches, and misconfigured security settings.

Testing Methodology

1

Scoping & Kick-off

Define objectives, in-scope assets, exclusions, testing mode (blackbox or greybox), credentials, test windows, and required approvals.

2

Reconnaissance

Gather passive and active information to map the Active Directory environment, identify key assets, and understand network topology and domain structure.

3

Threat Modeling

Analyze AD topology to identify attack paths through nested groups, Kerberos weaknesses, and trust misconfigurations. Prioritize domain controllers, service accounts, and high-privilege objects.

4

Vulnerability Analysis

Query the directory and perform credential testing to uncover weak service account passwords, delegation misconfigurations, vulnerable ACLs, NTLMv1 exposure, and missing patches on domain controllers.

5

Exploitation & Initial Access

Safely exploit validated AD weaknesses to demonstrate realistic privilege escalation and access scenarios without disrupting operations.

6

Post-Exploitation & Lateral Movement

Demonstrate lateral movement across the domain by compromising additional users or service accounts, escalating to Domain Admin, and exfiltrating sensitive data. Simulate persistence techniques relevant to AD environments.

7

Reporting & Debrief

Produce a comprehensive report with executive summary, scope, methodology, prioritized findings with PoCs, business impact, and actionable remediation, then present the results during a restitution meeting.

8

Retest (Optional)

Ensure all identified vulnerabilities have been properly fixed without introducing new risks.

FAQ

Frequently Asked Questions

  • Provide a basic user account with limited permissions for testing.
  • Allow network access onsite or via secure VPN.
  • Coordinate with SOC or EDR teams to temporarily whitelist tester activities and avoid false positives.

Active Directory is the backbone of authentication and access in most organizations. If compromised, attackers can gain full control of your network. This service uncovers misconfigurations, privilege escalation paths, and weak credentials to prevent domain-wide breaches.

The duration varies depending on environment size:

  • Small (≤300 workstations, one site): 5–7 business days
  • Medium (≤600 workstations, one site): 8–10 business days
  • Large (≥2 sites, up to 600 workstations): 10–15 business days

Factors such as segmentation, number of domain controllers, and access logistics can extend the duration.

All testing is safe and non-destructive. When performed in production, testing windows are coordinated to minimize impact. Potentially disruptive actions are executed only after agreement and approval.
