Crypto Portfolio Tracker

Security checks for vulnerabilities and agentic risk

Overview

This is a simple, visible crypto portfolio helper skill with no bundled code, persistence, credential handling, or hidden behavior found.

Before installing, users should understand that the skill appears localized for Chinese/Cantonese readers and should only provide public wallet addresses or read-only data unless future versions clearly document stronger safeguards for credentials or trading actions.

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
