Keygen

Security checks for vulnerabilities and agentic risk

Overview

The skill is a disclosed Keygen management connector with high-impact account actions guarded by user confirmation, though its optional CLI install snippet uses a risky pipe-to-shell pattern.

Install only if you intend to let the agent manage your Keygen account through OOMOL. Review destructive requests carefully before approving them, and verify the oo CLI installer from OOMOL before running any pipe-to-shell setup command.

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

External Script Fetching

Finding

The skill instructs the agent to install software by piping a remotely fetched script directly into a shell, which creates a classic supply-chain execution risk. If the install endpoint, transport, distribution pipeline, or upstream publisher is compromised, arbitrary code would execute immediately on the host with the agent's privileges.
