Write multi-event correlation rules that detect APT lateral movement by chaining Windows authentication events, process execution telemetry, and network connection logs across hosts. Uses Splunk SPL and Sigma rule format to correlate Event IDs 4624, 4648, 4688, and Sysmon Events 1/3 within sliding time windows to surface attack sequences invisible to single-event detections.

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/'implementing-siem-correlation-rules-for-apt' ] || [ -L ~/.agents/skills/'implementing-siem-correlation-rules-for-apt' ]; then echo 'A skill folder named implementing-siem-correlation-rules-for-apt 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 "$d" checkout --quiet '293ce9f76e3abcd5ba18db284688bc0d9ac6691d' -- 'plugins/asi/skills/implementing-siem-correlation-rules-for-apt' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/asi/skills/implementing-siem-correlation-rules-for-apt' ~/.agents/skills/'implementing-siem-correlation-rules-for-apt' && 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/'implementing-siem-correlation-rules-for-apt' ~/.claude/skills/'implementing-siem-correlation-rules-for-apt' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
