Security audit

whiss

Security checks for vulnerabilities and agentic risk

Overview

This is a simple brand-information skill with a small local script and no evidence of hidden malicious instructions or unsafe data access.

This skill appears safe from a security perspective, but it is mostly a namespace/brand info package rather than a real messaging integration. Expect limited functionality, and the bundled script may need packaging cleanup before it runs correctly.

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
