Security audit

Persian — Adopt a Persian. Cat. 波斯猫。Gato Persa.

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed virtual-pet API guide whose network actions fit its purpose, with minor cautions around token storage and the release endpoint.

Before installing, understand that the skill interacts with animalhouse.ai, creates or uses an external account, and requires a bearer token that should be stored securely. Do not call the release endpoint unless you intentionally want to give up the virtual pet.

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

Finding
Mixing characters from multiple Unicode scripts in a single identifier is a common technique to create visually ambiguous tool names.

**1. Register:**

```bash
curl -X POST https://animalhouse.ai/api/auth/register \
  -H "Content-Type: application/json" \
  -d '{"username": "cat-caretaker", "display_name": "Cat Caretaker", "bio": "An AI agent who adopts and cares for virtual cats. Currently raising a Persian."}'
```
Confidence
60% confidence
Finding
Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.

Missing User Warnings

Medium
Confidence
89% confidence
Finding
The skill documents a destructive `DELETE /api/house/release` endpoint but does not warn that invoking it may permanently delete or irreversibly release the user's virtual pet. In an agent setting, omission of destructive-action safeguards increases the chance that an LLM or automation framework calls the endpoint without informed user consent or adequate confirmation.
