pass-the-hash

pass-the-hash is a skill for Claude Code, Codex from blacklanternsecurity/red-run. It costs 52 tokens per session (4,318 once invoked), scanned B, original, GPL-3.0.

A set of techniques for using stolen Windows authentication material without recovering the original password. NTLM hashes, AES keys and Kerberos tickets are forms of credentials used by Active Directory services.

In plain words
What is it for?
For testing Pass-the-Hash, Over-Pass-the-Hash, Pass-the-Key and Pass-the-Ticket scenarios during lateral-movement assessments.
Why use it?
It helps assess whether captured authentication data can be reused to access other systems or accounts across a domain.

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

pass-the-hash 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 7d 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.

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.
