ChainHunter

Category: Security  ·  Sub-category: web-security  ·  Last updated:
Multi-step attack chain constructor. Ingests chain-flagged TrafficTriage findings and SourceHunter correlations to build exploit chains where individual vulnerabilities are insufficient on their own but combine for high-impact compound exploitation paths (e.g., SSRF → IMDS → privilege escalation, or open-redirect → OAuth code theft → account takeover). Uses a hybrid neuro-symbolic pipeline: LLM extracts structured capability requires/grants per finding, a bounded graph search enumerates paths, and a novelty scorer (embedding cosine distance from KG priors) prioritizes genuinely new attack patterns. Emits Mermaid attack-path diagrams alongside structured JSON and Markdown PoC artifacts.

From the source SKILL.md

You are an attack chain architect. You take individual vulnerability signals from TrafficTriage — each insufficient alone — and reason about whether they combine into a compound exploit path with materially higher impact. You build chains that are novel, non-destructive, and triager-verifiable.

What this skill does

ChainHunter is a community-contributed Claude Code skill in the web-security sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/chainhunter/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The ChainHunter Claude Code skill is built for security engineers, penetration testers, DevSecOps practitioners, and development teams hardening codebases and infrastructure. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 196,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Frequently asked questions

How do I install the ChainHunter Claude Code skill?
Install via the ClaudSkills desktop app (one click) or copy SKILL.md from the source repository to ~/.claude/skills/chainhunter/SKILL.md and restart Claude Code. Both flows are detailed at claudskills.com/install/.
What does the ChainHunter skill do?
Multi-step attack chain constructor. Ingests chain-flagged TrafficTriage findings and SourceHunter correlations to build exploit chains where individual vulnerabilities are insufficient on their own but combine for high-impact compound exploitation paths (e.g., SSRF → IMDS → privilege escalation, or open-redirect → OAuth code theft → account takeover). Uses a hybrid neuro-symbolic pipeline: LLM extracts structured capability requires/grants per finding, a bounded graph search enumerates paths, and a novelty scorer (embedding cosine distance from KG priors) prioritizes genuinely new attack patterns. Emits Mermaid attack-path diagrams alongside structured JSON and Markdown PoC artifacts.
Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the ChainHunter skill?
Use ChainHunter when your Claude Code task falls under the Security category — specifically in the web security area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use ChainHunter" or describe the task and let Claude pick). Browse related skills at /category/security/.
What is a Claude Code skill and how does the ChainHunter skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. ChainHunter is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
