Gpu Helper

Security checks for vulnerabilities and agentic risk

Overview

This skill is a simple local reference helper that only prints documentation and does not access credentials, network resources, or persistent system settings.

This appears safe to install as a reference-only helper. Users should be aware that the content is generic documentation, and one cheatsheet entry names a command that is not actually implemented.

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

Credential Access

Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Finding

The inline reference table claims there is a 'troubleshooting' command, but the dispatcher only implements 'debugging' and has no 'troubleshooting' case. This is a direct contradiction between the skill's embedded documentation and the actual available interface.
