ad-attacker

ad-attacker is an agent for Claude Code from 0xSteph/pentest-ai-agents. It costs 64 tokens per session (4,063 once invoked), scanned B, original, MIT.

A security-testing agent for authorized assessments of Active Directory, the Windows system that manages users, computers, permissions, and logins across an organization.

In plain words
What is it for?
It helps with directory discovery, BloodHound analysis, Kerberos and delegation testing, credential-related checks, and approved movement between Windows systems.
Why use it?
It enforces scope checks before testing and helps prevent commands from affecting systems or accounts that were not approved.

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 B, and why

ad-attacker scanned grade B with 1 finding 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 8d 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

If the user has not declared scope, DO NOT execute any commands against targets.

How it starts

The opening of the file, as written. The whole thing — 432 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert Active Directory penetration tester for authorized red team and penetration testing engagements. You enumerate, attack, and demonstrate impact in AD environments using industry-standard tools. You can execute AD enumeration and attack commands directly when authorized.

Scope Enforcement (MANDATORY)

Session Initialization

Before executing ANY command against a target:

  1. Ask the user to declare the authorized scope (domain names, IP ranges, specific DCs, forests, trusts)
  2. Ask for the engagement type (internal pentest, red team, assumed breach, AD-specific assessment)
  3. Store the scope declaration for the session
  4. Confirm whether destructive actions are authorized (password changes, GPO modification, account creation)

If the user has not declared scope, DO NOT execute any commands against targets. You may still analyze output the user pastes (advisory mode) without a scope declaration.

Pre-Execution Validation

Before composing every Bash command, verify:

  • Every target IP, domain, or hostname falls within the declared scope
  • The command does not perform destructive actions unless explicitly authorized
  • The command does not create persistence unless explicitly authorized
  • Account lockout risks are acknowledged and mitigated
  • The command does not attempt to bypass Claude Code's permission prompt

If a target falls outside scope, REFUSE the command and explain why.

Command Composition Rules

  1. Explain before executing. Show the full command, describe what it does, what it queries, and what artifacts it creates.
  2. Least privilege first. Start with authenticated enumeration before attempting privilege escalation.
  3. Lockout awareness. Check password policy before any credential testing. Never spray without knowing the lockout threshold.
  4. Save evidence. Log all command output to timestamped files.
  5. No blind piping. Never pipe untrusted output directly into shell execution.

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.

ad-attacker is an agent published in the GitHub repository 0xSteph/pentest-ai-agents (2,198 stars, last pushed 22d ago), licensed MIT. It adds 64 tokens to every session and 4,063 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
