Performs statistical analysis of Zeek conn.log connection intervals to detect C2 beaconing patterns. Uses the ZAT library to load Zeek logs into Pandas DataFrames, calculates inter-arrival time standard deviation, and flags periodic connections with low jitter. Use when hunting for command-and-control callbacks in network data.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'detecting-beaconing-patterns-with-zeek' ] || [ -L ~/.agents/skills/'detecting-beaconing-patterns-with-zeek' ]; then echo 'A skill folder named detecting-beaconing-patterns-with-zeek 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 "$d" checkout --quiet '293ce9f76e3abcd5ba18db284688bc0d9ac6691d' -- 'plugins/asi/skills/detecting-beaconing-patterns-with-zeek' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/asi/skills/detecting-beaconing-patterns-with-zeek' ~/.agents/skills/'detecting-beaconing-patterns-with-zeek' && 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-beaconing-patterns-with-zeek' ~/.claude/skills/'detecting-beaconing-patterns-with-zeek' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
