SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides a comprehensive guide to execute multi-step Kerberos attacks on Active Directory, targeting authentication via AS-REP roasting, Kerberoasting, golden/silver/diamond/sapphire tickets, delegation abuse, or pass-the-ticket attacks.

Core Features & Use Cases

  • Kerberos Attack Techniques: Offers expert-level guidance on AS-REP roasting, Kerberoasting, golden/silver/diamond/sapphire tickets, delegation attacks, pass-the-ticket, and overpass-the-hash.
  • Multi-Step Attack Chains: Combines Kerberos with ACL abuse, ADCS, and relay for end-to-end scenarios from foothold to domain admin.
  • End-to-End Scenarios: Provides detailed attack chains for lateral movement and domain admin escalation.

Frequently Asked Questions about active-directory-kerberos-attacks

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I perform Kerberoasting attacks against Active Directory?

Kerberoasting extracts service account credential hashes by requesting TGS tickets from Active Directory. This Skill provides expert guidance to execute Kerberoasting alongside AS-REP roasting for offline hash cracking and privilege escalation.

What is the difference between golden and silver ticket attacks in Kerberos?

Golden tickets forge TGTs using the domain's krbtgt hash, while silver tickets forge TGS tickets using a service account hash. This Skill guides you through executing both attacks, plus diamond and sapphire ticket variations for domain persistence.

How do I chain Kerberos attacks for lateral movement to domain admin?

You can chain Kerberos attacks by combining pass-the-ticket or overpass-the-hash with ACL abuse, ADCS exploitation, and relay attacks. This Skill maps multi-step attack chains from initial foothold to full domain admin escalation.

Can I abuse Kerberos delegation to escalate privileges in Active Directory?

Yes, Kerberos delegation abuse allows impersonation of users to access restricted services. This Skill covers techniques for exploiting unconstrained and constrained delegation as part of broader Active Directory authentication bypass campaigns.

Do I need prior knowledge of the Kerberos protocol to use these attack techniques?

Yes, you need a solid understanding of the Kerberos protocol and Active Directory infrastructure. This Skill provides advanced, multi-step attack execution guidance rather than foundational concepts, targeting administrative workflows involving AD authentication.

When should I use pass-the-ticket versus overpass-the-hash for AD authentication attacks?

Pass-the-ticket uses existing Kerberos tickets directly, while overpass-the-hash uses an NTLM hash to request new tickets. This Skill details both techniques to facilitate lateral movement across Active Directory environments.
