1. Disable libusb Installation

Group Policy: Configure Device Installation Restrictions. Block installation of devices with the class GUID 88bae032-5a81-49f0-bc3d-a4ff138216d6 (libusb's WinUSB/GUID). Also, block any unsigned driver.

2.2 Process Memory Patching

While LibUSB handles hardware, the tool also includes a software component. It scans running processes for known authentication flags (e.g., IsLicensed = 0 or IsLoggedIn = false) and patches them in memory using OS-specific APIs (WriteProcessMemory on Windows, ptrace on Linux). Because it is portable, it injects these patches without rebooting or modifying binaries on disk.
