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

Hunt NTLM/Negotiate information disclosure on internet-reachable IIS/SharePoint/Exchange. Anonymous NTLM Type-2 challenge capture leaks NetBIOS domain, internal DNS forest, computer name, AD timestamp via AV_PAIRS structure. Default Windows-installer hostnames (WIN-XXXXXXXXXXX pattern) signal lazy provisioning. Use when target advertises `WWW-Authenticate: NTLM` or `Negotiate` headers anonymously.

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/'hunt-ntlm-info' ] || [ -L ~/.agents/skills/'hunt-ntlm-info' ]; then echo 'A skill folder named hunt-ntlm-info already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/elementalsouls/Claude-BugHunter' "$d" && git -C "$d" checkout --quiet '8ac4242ee0a108e65ac1343b56cce6c50ba456ef' -- 'skills/hunt-ntlm-info' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/hunt-ntlm-info' ~/.agents/skills/'hunt-ntlm-info' && 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/'hunt-ntlm-info' ~/.claude/skills/'hunt-ntlm-info' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
