Security checks for vulnerabilities and agentic risk

Overview

This is a disclosed stock-scanning skill with financial-risk caveats but no evidence of hidden code, credential access, persistence, exfiltration, or destructive behavior.

Before installing, understand that this skill presents market signals and sample backtest data but does not include a clear financial-advice disclaimer. Do not rely on its `buy`, `watch`, or `hold` labels alone for investment decisions, and confirm whether any daily automatic backtest behavior creates platform scheduling you can control or disable.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep

Finding

The skill presents scored stock outputs with action labels such as 'hold', 'watch', and 'buy' plus backtest examples, but it does not provide any visible disclaimer that the content is informational only and not financial advice. In a trading context, this can encourage users to act on signals that may affect their finances, increasing the risk of harmful reliance or misinterpretation.

Natural-Language Policy Violations

Finding

The manifest description and most user-facing documentation are presented in Chinese, while the file title and commands are otherwise mixed-language. This imposes a language constraint on users without explicit opt-in or justification, which fits the policy's language/locale violation criteria.
