What's genuine?

A module anti Xposed hook, anti fake signature, anti virtual app (binder proxy), and optional anti odex, anti overlay.

Since 2019-03, Genuine switch to pure c for hide itself. If you want to hide your package name and / or class name, contact me, or do it like fill_XXX in genuine.c.

  • Xposed hook: hook any Java method in Xposed.

  • fake signature: fake your signature. genuine module requires usage of Apk Sign v2 or Apk Sign v3.

  • (optional) PLT Hook: currently only check jniRegisterNativeMethods by flag CHECK_HOOK.

  • virtual app (binder proxy): run your app in virtual app, like VirtualApp.

  • (optional) odex: modify odex codes without modify apk, like URET

  • (optional) overlay: overlay resources, prevent from loading apk from /data.

How to use?

  1. run java SimpleApkV2 <package-name> <apk>, save output to src/main/jni/genuine.h

  2. modify build.gradle for rootProject.XXX

  3. search FIXME in src/main/jni/genuine.c
