Unity HWID Fetcher

HWID Fetcher is a Windows-only developer utility for Unity that retrieves raw hardware and system identifiers directly from the operating system using PowerShell and Windows Management Instrumentation (WMI).

This tool is designed for developers, not end users, and is intended to be used as a building block for systems such as:

• Licensing and DRM

• Account or device moderation

• Analytics and diagnostics

• Security research

• Internal developer tooling

⚠️ This is not an anti-cheat solution by itself.
It provides access to system identifiers so developers can implement their own logic.

🔍 What Information Can Be Retrieved

The script can collect the following raw values at runtime:

• Physical disk serial numbers

• CPU Processor ID

• Motherboard (BaseBoard) serial number

• GPU PNPDeviceID

• MAC addresses (active network adapters)

• Unity device identifier

• Windows username

• Windows user SID

• Public IP address (via ipify)

All values are exposed through public fields and can be used however the developer chooses (hashed, logged, compared, sent to a backend, etc.).

🖥️ Platform Support

• ✅ Windows Desktop

• ❌ macOS

• ❌ Linux

• ❌ Android / iOS

• ❌ WebGL

• ❌ Consoles

PowerShell and WMI must be available on the target system.
