Active Directory Penetration Testing Services

Real World Security Testing for Active Directory Environments, Domain Infrastructure, and Identity Controls

Orasec delivers results driven Active Directory penetration testing services, identifying vulnerabilities that expose domain infrastructure, compromise identity controls, and undermine the security of Windows environments built on Active Directory. We go beyond surface level assessments by combining certified penetration testers, advanced methodologies, and real world attack simulation to uncover security weaknesses that genuinely impact organisations depending on Active Directory for authentication, authorisation, and access control across their environment.

Active Directory is the backbone of most enterprise networks. A single misconfiguration, weak delegation setting, or exploitable Kerberos implementation can give an attacker a direct path from a standard user account to full domain compromise making Active Directory penetration testing one of the highest value security assessments an organisation can invest in.

Why Active Directory Penetration Testing Matters

Active Directory misconfigurations and attack paths are consistently exploited in real world breaches, ransomware deployments, and advanced persistent threat operations. Attackers who gain initial network access target Active Directory immediately using privilege escalation techniques, lateral movement paths, and Kerberos attack vectors to move from a single compromised endpoint to complete domain control.

Orasec's Active Directory penetration testing methodology tests every layer of your domain environment from user account configurations and group policy settings to Kerberos implementations, delegation controls, and trust relationships ensuring your Active Directory security posture is resilient against the real world attack techniques targeting enterprise environments today.

The Active Directory Attack Surface

  • User Account and Password Security

    Weak passwords, password reuse, accounts with no expiry, and service accounts with excessive privileges create exploitable entry points across Active Directory environments. Password spraying, credential stuffing, and AS REP roasting attacks target misconfigured account policies to gain initial domain footholds.

  • Kerberos Attack Vectors

    Kerberos is the authentication protocol underpinning Active Directory. Kerberoasting, AS REP roasting, Pass the Ticket, Golden Ticket, and Silver Ticket attacks exploit Kerberos implementations to extract credential material, forge authentication tokens, and achieve persistent domain access without requiring plaintext credentials.

  • Privilege Escalation and Delegation

    Misconfigured delegation settings, excessive group memberships, and over privileged service accounts create privilege escalation paths from standard user access to domain administrator control. Unconstrained delegation, constrained delegation abuse, and resource based constrained delegation create high value escalation vectors across Active Directory environments.

  • Lateral Movement Paths

    Pass the Hash, Pass the Ticket, Overpass the Hash, and credential harvesting techniques allow attackers to move laterally across Active Directory environments using captured credential material pivoting from compromised endpoints to domain controllers and high value systems without triggering authentication failures.

  • Group Policy and ACL Misconfigurations

    Misconfigured Group Policy Objects, weak access control lists, and excessive object permissions create paths for privilege escalation, persistence, and domain compromise. WriteDACL, GenericAll, GenericWrite, and ForceChangePassword permissions on sensitive Active Directory objects give attackers direct paths to domain control.

  • Domain Trust Relationships

    Active Directory environments connected through domain and forest trusts create cross domain attack paths. Misconfigured trust relationships, SID history abuse, and trust transitivity exploitation allow attackers to move from a compromised child domain to parent domain and forest wide control.

Our Active Directory Penetration Testing Services

  • Active Directory Security Assessment

    We conduct comprehensive penetration testing of Active Directory environments covering user account security, group policy configurations, privilege assignments, delegation settings, and access control list weaknesses. Testing identifies exploitable misconfigurations and attack paths across the entire domain environment.

  • Kerberos Attack Simulation

    Our testers simulate real world Kerberos attacks including Kerberoasting, AS REP roasting, Pass the Ticket, Golden Ticket, and Silver Ticket techniques to identify exploitable service account configurations, weak encryption settings, and Kerberos implementation weaknesses across Active Directory environments.

  • Privilege Escalation Testing

    We assess Active Directory privilege escalation paths including misconfigured delegation settings, excessive group memberships, over privileged service accounts, and ACL based escalation vectors. Testing confirms whether standard user access can be escalated to domain administrator control through identified misconfigurations.

  • Lateral Movement Simulation

    Our testers simulate lateral movement across Active Directory environments using Pass the Hash, Pass the Ticket, credential harvesting, and remote execution techniques identifying paths from initial compromise to domain controllers and high value systems across the network.

  • BloodHound Attack Path Analysis

    We use BloodHound and advanced graph based analysis to map Active Directory attack paths, identify shortest paths to domain compromise, and uncover non obvious privilege escalation routes across complex Active Directory environments that manual analysis alone would miss.

  • Domain Trust and Forest Security Testing

    Our testing evaluates domain and forest trust relationships for misconfigured trust settings, SID history abuse opportunities, and cross domain attack paths that allow compromise to propagate from one domain to parent domains and forest wide infrastructure.

  • Active Directory Red Team Operation

    For organisations requiring comprehensive Active Directory security validation, Orasec conducts full red team operations simulating advanced persistent threat techniques across Active Directory environments from initial compromise through lateral movement to domain controller access and forest wide control.

Our Active Directory Penetration Testing Methodology

  1. Reconnaissance and Domain Enumeration

    Active Directory structure, user accounts, group memberships, service accounts, Group Policy Objects, trust relationships, and delegation configurations are enumerated to establish a complete picture of the domain environment and identify high value attack targets.

  2. Credential Attack Simulation

    Password spraying, AS REP roasting, and Kerberoasting techniques are applied to identify weak and exploitable credentials across user and service accounts without triggering account lockout policies.

  3. Privilege Escalation and ACL Analysis

    Group Policy configurations, access control lists, delegation settings, and group memberships are assessed for privilege escalation paths from standard user access to administrative and domain controller access.

  4. Lateral Movement and Credential Harvesting

    Following initial access, lateral movement techniques including Pass the Hash, Pass the Ticket, and credential harvesting are applied to simulate attacker movement across the domain environment toward high value systems and domain controllers.

  5. Domain Persistence Techniques

    We assess Active Directory environments for persistence opportunities including Golden Ticket viability, DCSync rights, AdminSDHolder abuse, and skeleton key attack paths confirming whether attackers could maintain persistent domain access following initial compromise.

  6. Detection and Response Evaluation

    Testing evaluates whether existing monitoring, alerting, and incident response capabilities detect and respond to simulated Active Directory attack activity revealing visibility gaps across domain security operations.

  7. Reporting and Remediation Guidance

    Findings are delivered in a detailed report with risk ranked vulnerabilities, exploitation evidence, attack path documentation, and prioritised remediation guidance tailored to Active Directory operational and administrative constraints.
