Executes authorized, advanced attack simulations against Active Directory environments to identify critical misconfigurations, weak credentials, and exploitable trust relationships. Utilizing industry tools like BloodHound, Mimikatz, and Impacket, this process simulates complex attacks such as Kerberoasting, Golden Ticket forging, and domain compromise path analysis, helping organizations validate their security posture against real-world threats.

This guide details the exploitation of the Active Directory Certificate Services (AD CS) ESC1 vulnerability. By leveraging misconfigurations, an attacker can request certificates impersonating high-privileged users (e.g., Domain Admins). The workflow covers AD enumeration, forging certificates with arbitrary Subject Alternative Names (SANs), authenticating via PKINIT, and ultimately escalating domain privileges using tools like mimikatz. Essential for authorized red team and penetration testing.

BloodHound is a powerful, graph-based reconnaissance tool specifically designed for Active Directory environments. It utilizes graph theory to map deep, hidden relationships and potential attack paths—such as privilege escalation chains—from compromised low-value accounts to high-value targets like Domain Admins. This tool is essential for authorized red team exercises and penetration testing engagements.

Details techniques for exploiting misconfigured Kerberos Constrained Delegation (KCD) in Active Directory. By abusing the S4U2Self and S4U2Proxy protocols, attackers can impersonate highly privileged users (e.g., Domain Admins) to achieve lateral movement or full domain compromise during authorized red-team engagements.

Kerberoasting is a credential access attack (T1558.003) targeting Active Directory service accounts with Service Principal Names (SPNs). This skill demonstrates using Impacket to request Kerberos TGS tickets for these accounts. The resulting RC4 or AES-encrypted tickets are then cracked offline using tools like Hashcat or John the Ripper, allowing attackers to recover service account credentials for lateral movement during authorized penetration testing or red-team engagements.

This guide details the exploitation chain for noPac, combining CVE-2021-42278 (sAMAccountName spoofing) and CVE-2021-42287 (KDC PAC confusion). It demonstrates how an attacker can escalate from a standard domain user to Domain Admin by manipulating Active Directory tickets and performing DCSync. Primarily used in authorized red-teaming and penetration testing to validate domain security.

This guide details the exploitation of the critical Zerologon vulnerability (CVE-2020-1472) in Active Directory Domain Controllers. It demonstrates the methodology for resetting the DC machine account password to empty, achieving full domain compromise. Subsequent steps include dumping domain credentials using DCSync. Essential for authorized red-teaming and security validation.

This guide details how to hunt for DCSync attacks (MITRE ATT&CK T1003.006) in Active Directory environments. It focuses on analyzing Windows Security Event ID 4662, specifically looking for DS-Replication-Get-Changes requests originating from non-domain-controller accounts. This technique is critical for incident response, purple teaming, and detecting unauthorized credential theft via Active Directory replication abuse.

This skill helps detect NTLM relay attacks (T1557.001) by analyzing Windows Security Event ID 4624 (logon type 3) for NTLMSSP usage. It flags critical anomalies such as IP-to-hostname mismatches, evidence of LLMNR/NBT-NS poisoning, rapid cross-domain authentication, and verifies SMB signing status. It is essential for proactive threat hunting and security incident investigation in Active Directory environments.

This skill guides security analysts through detecting MITRE ATT&CK T1098 account manipulation techniques. It analyzes Windows Security Event Logs (e.g., 4738, 4728) to find signs of unauthorized privilege escalation, group membership changes, or shadow admin account creation. It is essential for proactive threat hunting, incident response, and validating Active Directory security posture.

This guide details the deployment of Cisco Identity Services Engine (ISE) for comprehensive Network Access Control (NAC). It utilizes 802.1X authentication, MAC Authentication Bypass (MAB), and posture assessment to enforce security policies. Key features include integrating with Active Directory, assigning dynamic VLANs, and applying TrustSec Security Group Tags (SGTs) for advanced network segmentation in enterprise environments.

This guide details the process of performing Active Directory reconnaissance using BloodHound and SharpHound. It leverages graph theory to visualize hidden trust relationships, group memberships, and ACLs, mapping the shortest attack paths from a low-privilege compromised user all the way to Domain Admin rights. This is essential for red-teaming, security auditing, and identifying critical misconfigurations.
