## Description

Safetynet-fix is a tool for Android device attestation designed to bypass hardware and software integrity checks. Its primary purpose is to achieve Google SafetyNet compliance on devices with unlocked bootloaders, allowing software that requires specific security profiles to run on modified systems.

The project provides compatibility for rooted devices, specifically ensuring that banking and payment applications remain functional while maintaining root access. It manages the Magisk environment configuration to maintain these security-sensitive application requirements.

The system utilizes various interception and modification techniques, including dynamic library hooking, system property spoofing, and runtime memory patching. It also employs kernel-level module loading and Zygote-based process injection to hide root indicators and manipulate the reported integrity state of the device.
