kerberos-roasting

kerberos-roasting is a skill for Claude Code, Codex from blacklanternsecurity/red-run. It costs 35 tokens per session (3,978 once invoked), scanned B, original, GPL-3.0.

A penetration-testing skill for recovering passwords from Kerberos data in Active Directory, Microsoft's system for authenticating users and services. It extracts service-ticket or account-response hashes so they can be tested offline for weak passwords.

In plain words
What is it for?
Use it to perform Kerberoasting and AS-REP Roasting during an authorized assessment, then evaluate whether the recovered hashes can be cracked.
Why use it?
Some account configurations allow password hashes to be obtained without directly logging in. Offline password testing can reveal accounts that need stronger passwords or safer settings.

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

kerberos-roasting 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.

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.
