Teamgram Biz Service

Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only skill about Teamgram's biz_service and does not ask the agent to run code, access data, or change the environment.

Install this as reference material for Teamgram Server developers. Non-Chinese readers may need translation, but the artifact does not add executable behavior or request sensitive access.

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
