Skill Hunter

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed ClawHub search, vetting, and user-directed install helper with no evidence of hidden code execution or credential handling.

Install only if you are comfortable with the agent querying ClawHub public endpoints and helping run explicit ClawHub install, update, or uninstall commands. Continue to inspect candidate skills before installing them, as the skill itself recommends.

A.I.G

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

External Script Fetching

Confidence
90% confidence
Finding

Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.

### Red flags

- SKILL.md asks you to run shell commands that download external scripts
- Instructions tell you to `curl | bash` or `pip install` from non-standard sources
- Skill requires credentials but doesn't explain what they're used for
- Files contain base64-encoded content or obfuscated code
- The "setup" instructions do more than configure — they install, modify, or phone home
