auth-coercion-relay

auth-coercion-relay is a skill for Claude Code, Codex from blacklanternsecurity/red-run. It costs 105 tokens per session (8,583 once invoked), scanned B, original, GPL-3.0.

A security-testing guide for forcing computers to authenticate to an attacker-controlled listener and relaying that authentication elsewhere. It covers Windows authentication coercion and relay techniques across common network services.

In plain words
What is it for?
It supports testing PetitPotam, PrinterBug, DFSCoerce, ShadowCoerce, NTLM relay, LDAP, SMB, AD CS, MSSQL, and Kerberos relay scenarios.
Why use it?
It helps find cases where a system can be tricked into sending authentication data and where that data can be reused to gain permissions or move through the network.

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

auth-coercion-relay 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.

A mod that escalates privileges can change anything on the machine, not only the project.

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.
