Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed TikTok research workflow that depends on Gecho MCP, a Chrome extension, and a logged-in TikTok browser session, with no hidden code or unsupported prompt-leak behavior found.

Before installing, understand that this workflow depends on a third-party Gecho MCP server and Chrome extension using your logged-in TikTok browser session. Install it only if you are comfortable letting that integration read TikTok pages available in your browser and save collected results locally.

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
Vulnerability Patterns
  • System Prompt LeakageDirect Leakage, Indirect Extraction, Tool-Based Exfiltration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
