GreatWait

Security checks for vulnerabilities and agentic risk

Overview

GreatWait’s scheduling instructions fit its purpose and require user-approved destinations, scoped access, and controlled creation and cancellation.

GreatWait receives schedule and callback data and calls your approved destination. Use narrowly scoped credentials and review recurring schedules. Receivers must tolerate duplicate delivery, and cancellation cannot undo completed actions. The live service and optional CLI implementation were not verified.

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
