vutoolkit

Security checks for vulnerabilities and agentic risk

Overview

This instructions-only Vanderbilt toolkit skill openly handles sensitive university and Microsoft account sessions, but that access is disclosed and aligned with its student-account purpose.

Install only if you trust the external vutoolkit runtime and intend to connect your own Vanderbilt and Microsoft account. Use the host's secure vault, keep cookies/tokens/passwords out of chat and logs, and review any Microsoft Graph write action or passkey enrollment/recovery before allowing it.

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
