Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple Chinese-language gold price lookup guide that uses web extraction/search and does not include code, persistence, credential access, or hidden behavior.

Before installing, understand that the skill will use web extraction and search to fetch current gold-price data, and its trend commentary should be treated as informational rather than financial advice. Verify prices and dates with authoritative sources before making investment decisions.

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
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • YARA SignaturesMalware Match, Webshell Match, Cryptominer Match
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

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
88% confidence
Finding
The manifest says the skill triggers when users ask about a wide set of phrases such as gold price, shop price, bank bullion, international gold, trends, or future trends, but it does not define exclusions or negative examples. This makes activation conditions somewhat ambiguous and could cause unintended invocation for general finance or market-discussion queries.

Natural-Language Policy Violations

Low
Confidence
81% confidence
Finding
All user-facing instructions and examples are written only in Chinese, and the skill is framed specifically for domestic gold-price queries without stating that other languages are supported. This can be a locale/language policy issue if the organization requires user choice rather than implicit language enforcement.
