Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

ADCS abuse via Certipy — find vulnerable templates (ESC1-ESC15), request a certificate, authenticate as the target, dump the krbtgt. Full chain in 4 commands. Covers ESC1 (any SAN), ESC2 (any-purpose EKU), ESC3 (enrollment-agent), ESC4 (vulnerable ACL), ESC8 (NTLM relay to CA), ESC9/10/11/13.

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/'ad-certipy-esc-chain' ] || [ -L ~/.agents/skills/'ad-certipy-esc-chain' ]; then echo 'A skill folder named ad-certipy-esc-chain already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/BitterSecurity/Decepticon' "$d" && git -C "$d" checkout --quiet 'bdb1016c93ed687f61ac57481da298c25a47c8f5' -- 'packages/decepticon/decepticon/skills/standard/ad/certipy-esc-chain' && mkdir -p ~/.agents/skills && cp -R "$d"/'packages/decepticon/decepticon/skills/standard/ad/certipy-esc-chain' ~/.agents/skills/'ad-certipy-esc-chain' && 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/'ad-certipy-esc-chain' ~/.claude/skills/'ad-certipy-esc-chain' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
