ReZygisk is an Android root module framework and Zygote process injector. It functions as a native hooking engine and linker redirection tool designed to inject custom code into the Android Zygote process so that modifications are inherited by all spawned applications.
The project provides a decoupled abstraction layer and Zygisk API implementation, allowing system modules to operate independently of specific root management tools. This ensures that root modules remain stable and compatible across various kernel-level rooting solutions.
The framework includes capabilities for system process hiding and memory-level process hiding to bypass linker detection and security scanners. It utilizes dynamic symbol resolution and instruction-pointer native hooking to modify function behavior in memory.
