Security audit

非毒·分析魄

Security checks for vulnerabilities and agentic risk

Overview

This is a simple data-analysis guidance skill with no executable code, network behavior, persistence, or hidden privileged actions.

Before installing, consider that the skill may be invoked for general data-analysis requests; avoid using it on sensitive personal, financial, or business data unless you intend the agent to analyze that data. No code execution or privileged access was found.

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

Vague Triggers

Finding

The skill’s activation guidance is broad enough to trigger on generic requests like analyzing an Excel file or predicting trends, without clear boundaries on dataset type, sensitivity, or required user intent. In an agent system, this can cause over-invocation on common prompts, leading to unintended processing of sensitive business or personal data and reducing operator control over when the skill is used.

Natural-Language Policy Violations

Finding

The natural-language content of the skill is written in Chinese, but there is no statement that the language is optional, user-selectable, or limited to a justified Chinese-only context. This can violate language or locale policy when users are not given a choice.
