The binary will simply be called ‘AppName’ with no file extension. Remember that the app’s binary is located inside the file we downloaded from our device, in Payload/AppName.app. Now we can open Hopper, go to File -> Read Executable To Disassemble and select the app binary. In Part 1, we decrypted an app with bfinject and downloaded the. Once you’ve installed Hopper, we are ready to begin analyzing our chosen target app. The free version will do just fine for our purposes – with pro you will gain features allowing you to patch binaries, but it isn’t necessary for basic analysis and debugging. Hopper is a decompiler and disassembler that will allow us to view the assembly code of a cracked app’s binary. In this tutorial we’ll be using Hopper Disassembler. iOS Penetration Testing- Frida And Objection- Part 3.iOS Penetration Testing- Cycript A Runtime Manipulation- Part 2.iOS Penetration Testing- App Decryption And Jailbreaking- Part 1.I am specifically using iOS 11.1.2, but most of the tools in the series should work on any version of iOS 11. The series will be assuming that the user is using Electra jailbreak. I want to note that I won’t be going in depth into ARM and assembly code in general, as it simply would not fit into this post – however, I will refer you to other sources to learn about it. We will start with an introduction to binary analysis with ‘Hopper’, then we will move into debugging app store apps using ‘lldb’. This post is the 4th and final part a series giving an overview of the most useful app pentesting tools, research by Allyson IOS Penetration Testing Part 4 – Final Part
