Siri

Security checks for vulnerabilities and agentic risk

Overview

This is a Siri/HomeKit reference skill made of Markdown guidance, with no executable install path or hidden behavior found.

Review the HomeKit sections before use if you share a home, use presence automations, cameras, locks, or garage doors. These features can reveal occupancy patterns or affect physical devices, so they should be limited to trusted household members and reviewed in Apple Home and Location Services settings.

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

Session Persistence

Medium
Category
Rogue Agent
Content
- Check Console.app for intent logs

**Common Issues:**
- Intent not appearing: Check Info.plist IntentsSupported
- Parameters not captured: Verify @Parameter types match expected
- Shortcut not in app: Ensure AppShortcutsProvider is registered
Confidence
75% confidence
Finding
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Missing User Warnings

Low
Confidence
83% confidence
Finding
The skill describes presence and occupancy-related Siri/Home features such as 'Is anyone home?' and earlier location-based automations without warning that these rely on location sharing and can expose home/occupancy patterns. In a home-control context, omission of a privacy caution can lead users to enable sensitive features without understanding that household presence data may be shared or inferred.
