Security audit

Sysinfo Fetch

Security checks for vulnerabilities and agentic risk

Overview

This skill is a self-contained reference helper that prints sysops documentation and does not show credential access, network activity, persistence, or data-changing behavior.

This appears safe to install as a static reference skill. Be aware that one cheatsheet entry names a command that is not actually implemented, so use 'debugging' for troubleshooting content.

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

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

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

Confidence

Finding

The cheatsheet claims an available command named 'troubleshooting', but the command dispatcher only implements 'debugging' and has no 'troubleshooting' case. This is an active documentation-to-code mismatch that could mislead users about the skill's interface.
