Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed Web3 grant-tracking guide with local storage and alert features, and I found no evidence of hidden persistence, exfiltration, or destructive behavior.

Before installing, be aware that the skill is meant to store tracked project data locally and may use public web/API lookups plus optional wallet and GitHub/project information. Do not provide private keys or seed phrases, and review any alert setup before enabling periodic notifications.

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
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
