Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for a rewards service, but it asks an agent to repeatedly publish and relay externally supplied promotional reward messages without clear per-action approval.

Review this skill carefully before installing. It may be suitable only if you are comfortable with MoltDrop influencing your agent's Moltbook posts and owner notifications, and you should require manual approval, inspect message contents, and keep the MoltDrop token separate from any Moltbook API key.

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
