Security audit

Aurora Norfolk

Security checks for vulnerabilities and agentic risk

Overview

This skill is a narrow, disclosed aurora-planning helper for Norfolk, with proportionate web, HTTP, calculator, and small local state use.

Install this if you want a Norfolk-specific aurora watch. Configure any cron or scheduler entries deliberately, keep the state file limited to the listed aurora fields, and adjust the timezone only if you adapt the skill outside the UK.

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

Finding

The markdown explicitly says to always use Europe/London local time. This is a natural-language locale constraint, and the file does not indicate that users can choose a different locale or that this is presented as an opt-in preference.
