Docker Helper

Security checks for vulnerabilities and agentic risk

Overview

This Docker helper skill is a straightforward Docker command guide with disclosed cleanup risks and no hidden execution code.

Install only if you intend the agent to help run Docker commands on your machine. Review destructive operations such as container removal, image pruning, system pruning, and volume pruning before approving them because they can stop services or delete data.

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

Category
Privilege Escalation
Confidence
60% confidence
Finding

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