Security audit

Hunter

Security checks for vulnerabilities and agentic risk

Overview

The skill is mostly coherent for Hunter account operations, but its fallback setup tells the agent to run unverified remote installer scripts directly.

Review before installing. Use the skill only if you trust OOMOL and Hunter data flowing through the OOMOL connector. Do not let an agent automatically run the installer commands; install the oo CLI through a verified, user-controlled process and confirm any create, update, or delete action before it runs.

Vulnerability Patterns
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • 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
  • 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 users to install the CLI by piping a remote script directly into bash (curl ... | bash), which executes unverified code from the network immediately. If the install endpoint, transport path, hosting account, or upstream release pipeline is compromised, this becomes an arbitrary code execution path on the user's machine.

Finding

This markdown skill description defines activation in extremely broad terms that overlap with many routine user requests involving Hunter. It does not provide exclusions, negative examples, or context limits, which could cause unintended skill invocation whenever Hunter is merely mentioned.
