Bypassing iOS App Jailbreak Detection by Patching the Binary with Ghidra: Write-up of No-Escape Lab

This article explores jailbreak detection, a mechanism implemented by developers to prevent runtime manipulation, one of the key benefits of jailbreaking.
The blog covers types of jailbreak, detection methods, and the process and tools required to review and modify the binary of an iOS application using the Ghidra software.
To practice this, we will apply these concepts to the No Escape iOS application from MobileHackingLab, one of the more complex laboratories available.
This is a hands-on blog, so knowledge of jailbreak, some reverse engineering concepts, and the Ghidra software will be helpful.
Nevertheless, we will walk through the process from start to finish.
Some of the key takeaways are types of jailbreaks and how some common methods detect them.
We will also look at how to patch an application’s binary using Ghidra and other relevant tools.
Overall, this is a continuation of the previous blog on Environment Setup - MobileHackingLab.
