Security audit

DRG/DIP 工具包（MedGroup）

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward MedGroup DRG/DIP helper that uses a user-configured MCP connection and includes appropriate cautions for medical and credential handling.

Install only if you intend to use MedGroup's MCP service for Chinese DRG/DIP workflows. Use synthetic or de-identified case data where possible, keep the MedGroup key only in local MCP settings, and treat grouping or settlement output as professional reference rather than final clinical, coding, audit, or reimbursement authority.

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 natural-language instructions and user-facing guidance are written exclusively in Chinese, which effectively forces a specific language/locale for use of the skill. The file does not indicate that Chinese is optional, user-selected, or limited to a justified region-specific compliance context.
