VirusTotal 样本查询

Security checks for vulnerabilities and agentic risk

Overview

This skill is coherent and appears safe: it helps query VirusTotal for file hashes and does not include code, persistence, or hidden system changes.

Before installing, be comfortable providing malware hashes to VirusTotal and, if using an API key, only provide a key you are willing to use for this lookup. The skill is designed for personal/non-production use and includes sensible limits against uploads, downloads, login cookies, and key storage.

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 instructions require a specific language/locale presentation style: Chinese and English must be spaced in a prescribed way, implying the skill's output is expected in Chinese format. The file does not offer the user any language or locale choice, nor does it justify the constraint as region-specific compliance.
