active-directory-acl-abuse

active-directory-acl-abuse is a skill for Claude Code, Codex from ShulkwiSEC/bb-huge. It costs 54 tokens per session (2,683 once invoked), scanned A, a copy of active-directory-acl-abuse, MIT.

A playbook for abusing access-control lists in Active Directory. These lists define who can change users, groups, policies, credentials, and other directory objects.

In plain words
What is it for?
Use it to review BloodHound data, dangerous permissions such as GenericAll and WriteDACL, DCSync rights, shadow credentials, LAPS access, group changes, and GPO abuse.
Why use it?
It helps security testers find permission mistakes that can create paths from a low-privileged account to higher privileges. It also explains how such paths may connect with other Windows attacks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

active-directory-acl-abuse scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SKILL: AD ACL Abuse — Expert Attack Playbook

AI LOAD INSTRUCTION: Expert AD ACL abuse techniques. Covers BloodHound enumeration, dangerous ACEs (GenericAll, WriteDACL, WriteOwner, etc.), DCSync, shadow credentials, targeted kerberoasting, group manipulation, LAPS, and GPO abuse. Base models miss complex ACL chain exploitation and Cypher query patterns.

  • Common BloodHound attack paths with Cypher queries
  • Custom Neo4j queries for finding complex chains
  • Data collection and ingestion tips

1. BLOODHOUND ENUMERATION

Data Collection

# SharpHound (from Windows, domain-joined)
SharpHound.exe -c all --outputdirectory C:\temp --zipfilename bh.zip

# bloodhound-python (from Linux)
bloodhound-python -d domain.com -u user -p password -c all -dc DC01.domain.com -ns DC_IP

# Specific collection methods
SharpHound.exe -c DCOnly          # Fastest — only DC queries
SharpHound.exe -c Session         # Session data only (run periodically)
SharpHound.exe -c All,GPOLocalGroup  # Include GPO analysis

Key BloodHound Queries (Built-in)

  • "Find all Domain Admins"
  • "Shortest Paths to Domain Admins from Owned Principals"
  • "Find Principals with DCSync Rights"
  • "Shortest Paths to Unconstrained Delegation Systems"
  • "Find computers where Domain Users are Local Admin"

2. DANGEROUS ACE TYPES

ACE Effect on Users Effect on Groups Effect on Computers
GenericAll Change password, set SPN, modify attributes Add members RBCD, LAPS read, all attributes
GenericWrite Set SPN, modify attributes, shadow creds Add members RBCD, shadow credentials
WriteDACL Grant yourself any permission Same Same
WriteOwner Take ownership → then WriteDACL Same Same
ForceChangePassword Reset password without knowing old N/A N/A
AddMember N/A Add self/others to group N/A
AllExtendedRights Force change password, read LAPS N/A Read LAPS, BitLocker keys
ReadLAPSPassword N/A N/A Read local admin password
WriteSPN Set SPN → targeted kerberoast N/A N/A

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
