I: Decoding AndroidManifest.xml with resources. Make sure to add the libraries for the correct architecture in a suitable folder under /lib, e.g. The gadget libraries for each architecture can be found in FridaвЂ™s release page. $ apktool d myapp.apk -o extractedFolderДЄdd the frida native libraries ( frida-gadget) into the APKвЂ™s /lib folder.

Use apktool to decode the APK into itвЂ™s contents. Get the the APK binary of te application you want to test, e.g.The technique is simple, it can be described in short as вЂњadding a shared library & repackaging the Android applicationвЂќ. This technique will trigger checks against repackaging (unless those are separately bypassed).ДЄdding frida-gadget to an Android application.Avoids some sideeffects due to application checks for ptracing/debugging or checks for tampered environment.Enables testing on devices you cannot or do not want to root (obviously).In this post I will focus on Android, however things are pretty similar on iOS - frida can also be used on jailed Apple devices.ДЄ few advantages of using Frida on a non-rooted device: However, testing on a rooted device is not the only way! I am not sure why this technique is not more widely publicized, but Frida can also be used on non-rooted Android devices and non-jailbroken iPhones, without running frida-server at all. There are several reasons for this, but the most important is that the frida-server binary, which executes on the device, requires root privileges to attach to ( ptrace) the target application, in order to inject the Frida gadget library into the memory space of the process. Typically rooted Android devices are used during such reviews. It is often used, like Substrate, Xposed and similar frameworks, during security reviews of mobile applications. Frida is a great toolkit by used to build tools for dynamic instrumentation of apps in userspace.
