Mac Remote Access

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward macOS remote-access troubleshooting guide, with sensitive admin and unattended-access steps disclosed and aligned to that purpose.

Install only if you intend to manage remote access for a Mac you own or administer. Use dedicated passwords, narrow Tailscale ACLs to specific users and ports, and treat unattended AnyDesk/RustDesk startup as persistent remote access that should be reviewed periodically.

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
