Security audit

Freebie

Security checks for vulnerabilities and agentic risk

Overview

This skill is a small Chinese-language guide for finding free samples and coupons, with no code, persistence, credential use, or hidden behavior.

Before installing, expect this skill to be useful mainly for Chinese-language freebie, sample, coupon, and store-visit queries. Share only the location details needed for a specific search, and verify real-time store, queue, and coupon information with the merchant or source shown by the assistant.

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

Vague Triggers

Finding

The example trigger phrases are very broad and overlap with ordinary help-seeking language such as asking how to use a feature for a concrete task. This can cause unintended invocation of the skill in unrelated conversations, increasing the chance of unwanted data use, confusing responses, or bypassing more appropriate routing.
