Security checks for vulnerabilities and agentic risk

Overview

This is a simple nearby-ATM lookup skill whose location use is disclosed and aligned with its purpose, with only minor trigger-wording ambiguity.

Installers should expect this skill to use location when finding nearby ATMs. Only share precise location after an explicit ATM-finding request, and consider narrowing the trigger text to avoid activation during general financial or cash-withdrawal discussions.

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 manifest description says to invoke the skill when the user asks for "cash withdrawal near me," which is broad natural language that could overlap with general conversation and does not clearly constrain invocation to ATM lookup requests. The file does not provide negative examples or stronger activation boundaries to distinguish ATM search from other cash-withdrawal contexts.

Finding

The activation examples '取款机 附近 / ATMs near me / cash withdrawal' are ambiguously scoped, especially 'cash withdrawal,' which can overlap with broader financial-assistance intents rather than simple ATM lookup. This can cause the agent to invoke the skill in unintended contexts, potentially collecting or using precise location data when the user did not clearly request nearby ATM discovery.
