Security checks for vulnerabilities and agentic risk

Overview

This skill is a clearly disclosed Little Snitch command guide whose elevated firewall controls are expected for its purpose.

Install only if you intend to let the agent help administer Little Snitch. Treat sudo commands as high-impact: confirm profile, rule group, preference, restore, and traffic-capture actions before running them.

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
