Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly disclosed TikTok video/comment collection workflow that relies on Gecho's MCP and Chrome extension, with no hidden destructive or deceptive behavior found in the artifact.

Before installing, make sure you are comfortable installing the Gecho Chrome extension and configuring the Gecho Bridge MCP package, because they will interact with a logged-in browser session. Use it only for TikTok videos you intend to analyze, and review the external Gecho package/extension trust separately if your environment is sensitive.

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 manifest description is entirely in Chinese and presents the skill behavior and invocation guidance only in that language. Under the stated policy, forcing a specific language without user opt-in is a natural-language policy violation unless the locale constraint is documented and justified, which is not present here.
