Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple gold-price lookup guide that uses public web data and does not request local access, persistence, credentials, or code execution.

Before installing, understand that the skill relies on public market websites and search results for gold-price information, so outputs should be treated as reference data rather than financial advice. No local system access or persistent behavior was found.

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

description: 国内金价查询工具。用于查询黄金实时价格、银行金条价格、金店零售价、国际金价和黄金未来趋势分析。当用户询问金价、黄金价格、今日金价、金店价格、银行金条、国际金价、伦敦金、黄金走势或未来趋�
Confidence
80% confidence
Finding
YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).

Vague Triggers

Medium
Confidence
92% confidence
Finding
The manifest says the skill triggers when users ask about many general phrases such as '黄金价格', '今日金价', and '未来趋势', but it does not define boundaries, exclusions, or negative examples. This makes activation criteria broad enough to match ordinary finance-related conversation beyond a narrowly scoped invocation.

Natural-Language Policy Violations

Low
Confidence
86% confidence
Finding
The natural-language description and usage instructions are entirely in Chinese and present the skill as operating in that language, with no indication that users may choose another language. Under the stated policy, forcing a specific language without opt-in is a potential locale-policy issue unless the regional restriction is explicitly justified.
