Security checks for vulnerabilities and agentic risk

Overview

The skill provides paid phone calls and optional number leasing, with explicit spending limits and recipient-consent rules.

Set a spending limit and authorize recipients and call tasks before use. Phone numbers, task details, and call audio pass through external services. Independently check provider pricing and privacy terms; the skill's claim that nothing is stored could not be 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
