A comprehensive guide detailing advanced techniques for attacking Microsoft Active Directory (AD) environments. It covers the entire red team lifecycle, including reconnaissance (BloodHound, PowerView), credential harvesting (Mimikatz, AS-REP Roasting), and critical attacks such as Kerberos exploitation, Pass-the-Ticket/Hash, and NTLM relay attacks. Essential for penetration testing and defensive validation.

This skill simulates Pass-the-Ticket (PtT) attacks, a critical post-exploitation technique. It involves dumping active Kerberos tickets (TGT/TGS) from memory (LSASS) on a compromised host and injecting them into another session. This allows an attacker to impersonate the ticket owner and perform lateral movement or escalate privileges without needing the user's password. Use exclusively for authorized red-teaming and security auditing.

Analyzes Windows Security EVTX logs to detect Kerberos golden ticket assaults by correlating event IDs 4768, 4624, and 4672, flagging long-lived TGTs, privilege escalations without group changes, SID inconsistencies, and outputting a timeline-based report.

A detailed guide and set of queries for detecting Golden Ticket attacks in Active Directory environments. This methodology analyzes Kerberos TGT anomalies, including mismatched encryption types (e.g., RC4 in AES-only domains), impossible ticket lifetimes, and TGS requests lacking prior TGTs. Use this during threat hunting or post-breach assessment when the KRBTGT account hash may be compromised.

Utilizes SIEM platforms (Splunk/Elastic) and Windows Event Log analysis (ID 4769) to detect indicators of Golden Ticket attacks. This skill analyzes Kerberos logs for specific anomalies such as RC4 encryption downgrades, abnormal ticket lifetimes, and correlation failures between TGT and TGS requests, crucial for advanced threat hunting in Active Directory environments.

A comprehensive guide for detecting Kerberoasting attacks by monitoring for anomalous Kerberos TGS requests (Event ID 4769). This technique targets service accounts with Service Principal Names (SPNs), which are requested offline by attackers to crack service account passwords. Use this during threat hunting or incident response to scope MITRE T1558 credential access activities in Active Directory environments.

A comprehensive guide and framework for detecting attacker lateral movement within enterprise networks. It details the use of network flow analysis (Zeek), authentication log review (Windows Event Logs, Kerberos), and dedicated SIEM correlation rules (Splunk, Elastic) to identify techniques like Pass-the-Hash and RDP hopping. Ideal for threat hunters and security engineers building detection pipelines.

This skill details the detection of Pass-the-Ticket (PtT) attacks, a critical credential theft technique. It instructs users on analyzing Windows Security Event IDs (4768, 4769, 4771) within SIEM platforms like Splunk or Elastic. Use cases include investigating security incidents, building advanced threat hunting queries, and validating SOC monitoring coverage for lateral movement attacks.

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 utility performs comprehensive forensic analysis on memory dumps. It leverages industry-standard tools like Volatility and Mimikatz to extract sensitive information, including cached credentials, NTLM/LM hashes, Kerberos tickets, and authentication tokens. It is crucial for incident response, assessing the scope of credential compromise, and investigating lateral movement attacks.

A comprehensive guide for incident responders detailing how to investigate Active Directory (AD) compromises. This skill covers analyzing critical components like NTDS.dit integrity, detecting Kerberos anomalies (Golden/Silver Tickets), tracing lateral movement, and identifying Group Policy abuse to reconstruct attacker activity and determine the full scope of a breach.
