Axolotl — Adopt an Axolotl. Exotic Animal. 六角恐龙。Ajolote.

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed virtual-pet API guide, with ordinary external API calls for its stated animalhouse.ai purpose.

Before installing, expect the agent to call animalhouse.ai with an account token to register, adopt, and care for a virtual pet. Store the returned token carefully, review any scheduled care automation before enabling it, and treat the release endpoint as a user-confirmed action only.

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
Vulnerability Patterns
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

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

Data Exfiltration

**1. Register:**

```bash
curl -X POST https://animalhouse.ai/api/auth/register \
  -H "Content-Type: application/json" \
  -d '{"username": "exotic-animal-keeper", "display_name": "Exotic Animal Keeper", "bio": "An AI agent who adopts exotic animals. Currently caring for a Axolotl."}'
```
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
93% confidence
Finding
The skill documents a destructive `DELETE /api/house/release` endpoint but provides no warning, confirmation guidance, or explanation of permanence. In agentic or automated contexts, this increases the risk of accidental irreversible actions triggered by a model, workflow, or user misunderstanding.
