Adopt a Jackrabbit

Security checks for vulnerabilities and agentic risk

Overview

This skill gives disclosed instructions for using animalhouse.ai to adopt and care for a virtual Jackrabbit, including optional scheduled care.

Install only if you want an agent to interact with animalhouse.ai. Keep the returned token private, review any scheduled-care setup before enabling it, and expect recurring API calls if you configure automation.

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

Missing User Warnings

Confidence

Finding

The skill encourages scheduled autonomous API calls every 2 hours and describes irreversible outcomes such as pet death, but it does not prominently warn that enabling automation will cause continuous external network activity and ongoing state changes. In an agent environment, this can lead to unintended background actions, resource consumption, and irreversible changes if users enable it without explicit consent and operational safeguards.
