Use when attacking a Windows Active Directory domain — Kerberos roasting/delegation, coercion + NTLM/Kerberos relay (CVE-2025-33073), ADCS ESC1-16 (EKUwu), ticket forgery & DCSync, dMSA BadSuccessor (CVE-2025-53779), BloodHound attack-path enumeration, domain dominance.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Active Directory Attacks

## When to Activate

- Attacking Windows domain environments after gaining any domain foothold (creds, hash, or unauth network position)
- Kerberos exploitation: Kerberoasting, AS-REP roasting, delegation (RBCD/constrained/unconstrained), ticket forgery
- Coercion + NTLM/Kerberos relay chains (PetitPotam/DFSCoerce → LDAP/ADCS, NTLM reflection CVE-2025-33073)
- ADCS certificate-template abuse (ESC1-ESC16) and certificate-based domain takeover
- dMSA / BadSuccessor privilege escalation on Windows Server 2025 domains
- BloodHound CE attack-path discovery, lateral movement, DCSync, and domain-dominance persistence

## Technique Map

| Technique | ATT&CK | CWE | Reference | Script |
|-----------|--------|-----|-----------|--------|
| BloodHound CE / SharpHound enumeration | T1482 | CWE-732 | references/bloodhound-enum-lateral.md | scripts/ad_recon.py |
| Password spray / PtH / PtT lateral movement | T1550.002, T1550.003 | CWE-522 | references/bloodhound-enum-lateral.md | scripts/ad_recon.py |
| LAPS / gMSA password read | T1003 | CWE-522 | references/bloodhound-enum-lateral.md | scripts/ad_recon.py |

How to install

The exact contents, by fingerprint
mdr add hypnguyen1209/offensive-claude/active-directory-attack@sha256:4e50cc891aa9edfc

The line at the top of this page pins the label git:20260629.9f4a1a5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
