Security audit

Sshkey

Security checks for vulnerabilities and agentic risk

Overview

This is a small SSH key reference skill that only prints local documentation and does not access credentials, network services, or persistent system state.

Reasonable to install if you want static sshkey reference text. Expect generic guidance rather than a functional SSH key manager, and note the minor command/documentation mismatch.

A.I.G

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 users can run a 'troubleshooting' command, but the dispatcher only recognizes 'debugging' and has no 'troubleshooting' branch. This is a direct contradiction between documentation embedded in the skill output and actual behavior.
