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.

Pass-the-Ticket (PtT) is a critical post-exploitation technique used in red teaming and offensive security assessments. It allows an attacker to move laterally across a network by utilizing stolen Kerberos tickets (TGT or TGS) without ever needing the user's password. This skill outlines the process of dumping tickets from memory (e.g., LSASS) and injecting them into a current session to impersonate a high-privilege user for access to sensitive resources.

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.

This skill guides the detection of Golden Ticket attacks within Active Directory by analyzing Kerberos logs (Event IDs 4768, 4769, 4771). It hunts for critical anomalies, such as mismatched encryption types (e.g., RC4 in AES environments), impossible ticket lifetimes, or service tickets appearing without a prior ticket grant request. This is essential for post-breach assessment and advanced threat hunting in domain environments.

This skill provides structured procedures for detecting Golden Ticket attacks, a severe threat involving forging Kerberos Tickets in Active Directory. It analyzes Windows Event ID 4769 for indicators such as RC4 encryption downgrades, abnormal ticket lifetimes, and inconsistencies in TGS/TGT requests. Designed for SOC analysts and threat hunters using SIEM platforms (Splunk/Elastic) to enhance security monitoring coverage against credential theft.

This guide outlines a comprehensive threat hunting methodology for detecting Kerberoasting attacks. It focuses on monitoring for anomalous Kerberos TGS requests targeting service accounts with SPNs, which are indicators of brute-force or offline password cracking attempts. Use this workflow during proactive security assessments, incident response, or when analyzing SIEM/EDR telemetry to identify potential lateral movement.

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 provides a structured approach to detecting Pass-the-Ticket (PtT) attacks, a severe credential theft technique utilizing stolen Kerberos tickets (TGT/TGS). It involves analyzing Windows Security Event IDs (4768, 4769, 4771) within SIEM platforms like Splunk or Elastic. Use cases include incident response, building advanced threat hunting queries, and validating security monitoring coverage against MITRE ATT&CK techniques.

This technique details how to exploit misconfigurations within Kerberos Constrained Delegation (KCD) in Active Directory. By leveraging S4U2self and S4U2proxy extensions, attackers can impersonate highly privileged users (e.g., Domain Admins) to request service tickets, enabling lateral movement and full domain compromise during authorized red teaming or penetration testing.

A comprehensive guide detailing the Kerberoasting technique (T1558.003) used in Active Directory environments. This method exploits service accounts by requesting and subsequently cracking Kerberos TGS tickets offline, allowing attackers to compromise credentials. Instructions cover enumeration, ticket request, cracking with tools like Hashcat/John the Ripper, and credential validation, for authorized red team and penetration testing purposes.

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.
