Security checks for vulnerabilities and agentic risk

Overview

This is a Chinese-language homework coaching skill that uses bundled PowerPoint templates and does not show hidden execution, credential access, persistence, or data exfiltration.

Install this only if you are comfortable giving the assistant the learner and company details needed to complete the course templates. Review generated PPTX files before sharing them, especially pages containing personal photos, business goals, employee/customer information, or unfinished "待补充" items.

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

Natural-Language Policy Violations

Category
Not specified by scanner
Confidence
77% confidence
Finding

The display name and description are written entirely in Chinese, which suggests the skill may be intended to operate in that language, but the file provides no indication that users can choose another language or explicitly opt in to a Chinese-only experience. Under the policy, a language or locale constraint should either offer user choice or be clearly documented and justified.
