Security checks for vulnerabilities and agentic risk

Overview

The skill provides a purpose-aligned giveaway workflow with user-controlled draws and expected sharing of entrant names with Perkadoo.

Proceed if you are comfortable sending the complete cleaned list of entrant names or handles to Perkadoo and publishing giveaway results. Use only necessary entrant information, verify the list before confirming a final draw, and enable the full connector only if you need its additional entry-management tools. This review covers the skill instructions, not the remote service's implementation or data-retention practices.

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

The workflow instructs the agent to submit entrants' names or handles to a third-party service. Although the skill explains that results are public and requires confirmation that the draw is final, it does not tell the user that the complete entrant list will be transmitted; the confirmation covers only the entrant count, winners count, and prize.
