Security checks for vulnerabilities and agentic risk

Overview

This is a security-advice skill that gives disclosed hardening guidance and does not ship code, persistence, credential handling, or hidden execution.

Before installing, treat the security claims and linked GitHub references as advice to verify independently. The only persistent local change suggested is making memory files read-only, which may affect normal OpenClaw memory updates until permissions are changed back.

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
