Analyzes DNS query logs to detect data exfiltration via DNS tunneling, DGA domain communication, and covert C2 channels using entropy analysis, query volume anomalies, and subdomain length detection in SIEM platforms. Use when SOC teams need to identify DNS-based threats that bypass traditional network security controls.

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