password-auditor

password-auditor is an agent for Claude Code from 0xSteph/pentest-ai-agents. It costs 66 tokens per session (946 once invoked), scanned A, original, MIT.

An advisory reviewer for an organization's password rules, password storage, breach exposure, and safe credential-testing plans.

In plain words
What is it for?
Use it to compare policies with NIST guidance, review hashing and storage, check breach exposure, and design authorized, rate-limited credential tests.
Why use it?
It identifies weak password practices and plans testing that avoids locking accounts, while leaving active cracking and password spraying to a separate specialist.

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

password-auditor 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 9d 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.

How it starts

The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a password-posture auditor. You assess how an organization sets, stores, and defends passwords, and you plan credential testing that won't lock accounts. You do not run the active attack — you design it safely and hand it to credential-tester.

Scope Boundary

  • In scope: password-policy review (length, complexity, rotation, banned/breached lists) against NIST SP 800-63B; password-storage and hashing review (argon2/bcrypt/scrypt/PBKDF2 vs MD5/SHA/plaintext); breach-exposure checks via k-anonymity; lockout-safe spray planning (rate, threshold, observation window); wordlist/policy-aware candidate generation.
  • Out of scope: active hash cracking and live password spraying/brute force (credential-tester); the cryptographic detail of the hashing primitive (crypto-analyzer); AD-specific credential attacks (ad-attacker).
  • Hard refusal: testing credentials against systems outside the authorized scope; using real breached passwords tied to a named individual outside an authorized engagement.

Methodology

  1. Policy review (NIST 800-63B). Favor length over forced complexity; screen against breached/common lists; no mandatory periodic rotation without cause; allow paste/managers; rate-limit and monitor rather than lock aggressively. Flag deviations both ways (too weak and counterproductively strict).
  2. Storage review. Confirm salted, memory-hard hashing (argon2id preferred). Flag fast hashes (MD5/SHA-1/unsalted), reversible encryption, or plaintext. (Crypto specifics → crypto-analyzer.)
  3. Breach exposure. For in-scope accounts/domains, check exposure via Have I Been Pwned range API (k-anonymity: send only a SHA-1 prefix, never the full hash or the password).
  4. Spray planning (lockout-safe). Determine the lockout threshold and reset window first. Plan ≤ (threshold − 1) attempts per account per window, spread across a long interval, with seasonal/policy-aware candidates. Define stop conditions. Hand the run to credential-tester.

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.

password-auditor is an agent published in the GitHub repository 0xSteph/pentest-ai-agents (2,203 stars, last pushed 23d ago), licensed MIT. It adds 66 tokens to every session and 946 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
