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

Baseline the EFI System Partition and hunt malicious EFI binaries such as ESPecter, BlackLotus, Bootkitty, and Glupteba by mounting the ESP, hashing and verifying boot loaders, scanning with YARA, and flagging anomalous non-EFI files or out-of-band bootloader changes. Use during proactive threat hunts for firmware/bootkit persistence (MITRE ATT&CK T1542.003) or when investigating suspected UEFI-level compromise that survives OS reinstall.

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/'hunting-bootkits-in-efi-system-partition' ] || [ -L ~/.agents/skills/'hunting-bootkits-in-efi-system-partition' ]; then echo 'A skill folder named hunting-bootkits-in-efi-system-partition 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 "$d" checkout --quiet '54a798831d2266a3ca61ce68a7acb80b81160d57' -- 'skills/hunting-bootkits-in-efi-system-partition' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/hunting-bootkits-in-efi-system-partition' ~/.agents/skills/'hunting-bootkits-in-efi-system-partition' && 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/'hunting-bootkits-in-efi-system-partition' ~/.claude/skills/'hunting-bootkits-in-efi-system-partition' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
