Fine to try. Some of what it can do is expected: a security skill usually runs scanners and checks websites.

Trigger machine account authentication with PetitPotam (MS-EFSR) and Coercer (MS-RPRN, MS-DFSNM, MS-FSRVP, MS-EVEN) via Coercer's scan/coerce/fuzz modes, feeding the coerced NTLM auth into a relay against AD CS Web Enrollment (ESC8), LDAP (RBCD), or SMB. Use in authorized engagements to complete a coercion-relay chain against a Domain Controller, or to validate coercion detections and signing/EPA mitigations.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'coercing-authentication-with-coercer-petitpotam' ] || [ -L ~/.agents/skills/'coercing-authentication-with-coercer-petitpotam' ]; then echo 'A skill folder named coercing-authentication-with-coercer-petitpotam already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/mukul975/Anthropic-Cybersecurity-Skills' "$d" && git -C "$d" checkout --quiet '54a798831d2266a3ca61ce68a7acb80b81160d57' -- 'skills/coercing-authentication-with-coercer-petitpotam' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/coercing-authentication-with-coercer-petitpotam' ~/.agents/skills/'coercing-authentication-with-coercer-petitpotam' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'coercing-authentication-with-coercer-petitpotam' ~/.claude/skills/'coercing-authentication-with-coercer-petitpotam' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
