Security audit

Piston

Security checks for vulnerabilities and agentic risk

Overview

This skill is a static Piston reference helper that prints documentation and does not access credentials, networks, files, or persistent system features.

This appears safe for normal use as a local reference skill. If your agent auto-routes skills from very broad terms like security or intro, consider invoking it explicitly as a Piston reference to avoid irrelevant documentation appearing in unrelated tasks.

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

Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Confidence

Finding

The skill exposes very generic single-word command triggers such as 'intro', 'security', and 'patterns'. In agent environments where skills may be auto-selected or matched by loose natural-language routing, these underspecified triggers can cause unintended invocation, leading the agent to surface this skill in unrelated contexts or override a more appropriate skill.
