Apple Serial Lookup

Security checks for vulnerabilities and agentic risk

Overview

This skill performs a disclosed Apple serial-number lookup workflow, but users should know that web lookups may send the serial number to third-party sites.

Install only if you are comfortable using it for Apple serial lookups. Prefer the local decoder first, and ask the agent not to send the full serial number to search engines or third-party lookup sites unless you explicitly approve that disclosure.

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
  • MCP Tool PoisoningHidden Instructions, Unicode Deception, Parameter Description Injection
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Finding

The description overstates the skill's coverage and capabilities. The code is a standalone local serial decoder focused on old-format Apple serial numbers. It can infer manufacturing location and rough production week/year, and it contains only a tiny built-in model mapping database (some MacBook Pro and iPhone 7 variants). It does not implement general lookup for iPhones, iPads, Macs, Apple Watch, Apple TV, and iPods as claimed, nor does it check warranty status. For post-2021/new randomized serials, it explicitly cannot identify the device locally. So the declared description does not accurately represent the actual behavior.

Finding

The skill instructs the agent to send full Apple serial numbers to third-party sites and search engines without any warning or minimization. Serial numbers are device identifiers that can be sensitive, and disclosing them to external services may expose ownership, warranty, or device metadata to parties unrelated to the user’s request.
