Detects and analyzes fileless malware that operates entirely in memory using PowerShell, WMI, .NET reflection, registry-resident payloads, and living-off-the-land binaries (LOLBins) without writing traditional executable files to disk. Activates for requests involving fileless threat detection, in-memory malware investigation, LOLBin abuse analysis, or WMI persistence examination.

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/'detecting-fileless-malware-techniques' ] || [ -L ~/.agents/skills/'detecting-fileless-malware-techniques' ]; then echo 'A skill folder named detecting-fileless-malware-techniques already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/plurigrid/asi' "$d" && git -C "$d" checkout --quiet '293ce9f76e3abcd5ba18db284688bc0d9ac6691d' -- 'plugins/asi/skills/detecting-fileless-malware-techniques' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/asi/skills/detecting-fileless-malware-techniques' ~/.agents/skills/'detecting-fileless-malware-techniques' && 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/'detecting-fileless-malware-techniques' ~/.claude/skills/'detecting-fileless-malware-techniques' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
