playbook-ad

playbook-ad is a skill for Claude Code, Codex from s0ld13rr/pentestcode. It costs 68 tokens per session (646 once invoked), scanned A, original, MIT.

A playbook for testing the security of Microsoft Active Directory, the system many Windows organizations use to manage users, computers, and permissions. It covers Kerberos, LDAP, Group Policy, certificates, and movement between machines.

In plain words
What is it for?
Use it during an approved Windows domain security test for domain discovery, user and credential checks, delegation and certificate checks, lateral movement, and paths to domain administrator access.
Why use it?
It provides a staged checklist and example commands for finding accounts, permissions, configuration weaknesses, and possible paths to higher access during an authorized assessment.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

playbook-ad 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 1mo 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.

What it actually says

Active Directory — Decision Tree

Without credentials

  • AS-REP Roasting: accounts with "Do not require Kerberos preauthentication" → offline crack (hashcat -m 18200). No creds needed.
  • Null session: enum4linux-ng -A DC → user list for spray.
  • Password spraying: one password, many users. Lockout-safe: 1 attempt per 30+ min. Try Season2024!, Company1!.
  • NTLM relay: only if SMB signing disabled.

With any valid user

  • Kerberoasting: any domain user can request TGS for SPN accounts → offline crack (hashcat -m 13100). Service accounts often have weak passwords.
  • BloodHound: bloodhound-python -u USER -p PASS -d DOMAIN -c all → shortest path to DA.
  • GPP passwords: netexec smb DC -u USER -p PASS --gpp-passwords — legacy, still found.

Delegation abuse

  • Unconstrained: machine impersonates ANY user to ANY service. Coerce DC auth (PrinterBug/PetitPotam) → capture TGT → DCSync.
  • Constrained: impersonate users to SPECIFIC services via S4U2Self + S4U2Proxy.
  • RBCD: if you can write msDS-AllowedToActOnBehalfOfOtherIdentity → impersonate admin. Discover: impacket-findDelegation DOMAIN/USER:PASS -dc-ip DC

ADCS — check IMMEDIATELY if present

ESC1–ESC8, many give instant DA:

  • ESC1: enrollable template with SAN override → request cert as DA
  • ESC4: template owner → modify template → create ESC1
  • ESC8: HTTP enrollment → NTLM relay to ADCS web endpoint Tool: certipy find -u USER@DOMAIN -p PASS -dc-ip DC -vulnerable

Four classic paths to DA

  1. AS-REP → crack → Kerberoast → crack SPN → ACL path → DA
  2. Spray → creds → BloodHound → ACL abuse (GenericAll/WriteDACL) → DA
  3. Null session → user list → spray → delegation abuse → DA
  4. NTLM relay → local admin → cred dump → lateral → DCSync

DCSync (endgame)

Requires "Replicating Directory Changes" rights: impacket-secretsdump DOMAIN/USER:PASS@DC → all domain hashes + krbtgt. With krbtgt hash → Golden Ticket → persistent DA.

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.
