Security audit

A Stock Trading Assistant

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed China A-share market assistant that fetches public stock data and gives analysis, with financial-risk caveats but no evidence of hidden access, exfiltration, persistence services, or destructive behavior.

Install only if you want a China A-share focused analysis helper. Verify any market data independently, do not treat generated buy/sell or position-size suggestions as professional financial advice, and be aware that the referenced helper scripts and watchlist files were not present in the inspected artifact.

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

Vague Triggers

Medium
Confidence
94% confidence
Finding
The manifest trigger is extremely broad and is likely to activate on nearly any A-share-related finance query, causing the skill to take over conversations beyond narrowly scoped stock lookup tasks. In a high-risk domain like trading, over-triggering increases the chance of unsolicited investment guidance, incorrect routing, and the model performing actions or giving advice when the user did not explicitly request this specialized skill.

Natural-Language Policy Violations

Medium
Confidence
90% confidence
Finding
The description and role definition are written to serve only the China A-share market and present the interaction policy entirely in Chinese, with no indication that users may choose another language. Under the policy, forcing a specific language or locale without user opt-in is a natural-language policy violation unless clearly offered as a choice or justified as a documented locale constraint.
