Volcengine ARK Entry

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small Volcengine ARK API helper whose external request template matches its stated purpose.

Install only if you intend to use Volcengine ARK. Treat prompts and API keys as sensitive, and avoid sending secrets or private data to the ARK endpoint unless your account and data-handling requirements allow it.

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
