Crypto Alert Agent

Security checks for vulnerabilities and agentic risk

Overview

The skill is a transparent crypto alert and portfolio tracker that uses Telegram notifications, but users should understand that portfolio-related alerts may leave their local environment.

Install only if you are comfortable sending crypto alert activity and possible portfolio value information through Telegram. Because the referenced run.sh implementation is not included in the inspected package, review any actual script before running it or placing it on a cron schedule.

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 skill instructs users to store a Telegram chat ID in a credentials directory and send notifications externally, but it does not clearly warn that alerts and portfolio-related information will be transmitted to a third-party messaging platform. While a chat ID is not highly secret by itself, it is still identifier data and its use enables external delivery of potentially sensitive financial information. In a crypto portfolio context, this increases privacy risk because holdings, trading interests, and alert activity may reveal valuable personal financial behavior.
