An App Zygote is an application-specific Zygote process that preloads resources and forks isolated services for the application. +To function correctly, the App Zygote must transition into the restricted context of the isolated service. Because of this requirement, it is indispensable for it to have the permission to [query and check SELinux access rules](https://android.googlesource.com/platform/system/sepolicy/+/master/private/app_zygote.te#:~:text=%23%20Check%20validity%20of%20SELinux,selinux_check_access(app_zygote)). +This inherent design makes it the perfect candidate to query SELinux without being restricted by normal untrusted app constraints. + +In this implementation, the `AppZygote` uses the `SELinux.checkSELinuxAccess` API to analyze the system's global SELinux policies for "dirty" rules injected by common root and hooking solutions. +Developers can easily extend this implementation by adding the specific SELinux rule characteristics of other future popular su solutions or root tools. +Because the app zygote and zygote share code, SELinux permissions must be checked, otherwise, the process will crash, so this detection cannot be bypassed in userspace. +The only way to circumvent this detection is by modifying the kernel itself. + +## License + +Licensed under the Apache License, Version 2.0 (the "License");
