Security checks for vulnerabilities and agentic risk

Overview

This is a plain-language A-share trading strategy skill with financial-risk caveats needed, but no hidden code, persistence, credential handling, or data exfiltration behavior.

Before installing, understand that this skill may steer stock-trading decisions and uses aggressive short-term trading assumptions. Treat it as informational only, verify market data independently, and do not let an agent place trades or access brokerage accounts without explicit, separate controls.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • 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 gives specific, actionable short-term trading instructions, position sizing, stop-loss rules, and security-selection criteria without any warning that this is risky financial guidance or may cause monetary loss. Because it is framed as an operational strategy rather than general education, users may reasonably rely on it as investment advice and suffer losses.

Confidence
