However jailbroken devices are very useful to observe and reverse applications. Those protected with anti-jailbreak code are then more tedious to reverse thus complicating their security assessment or the development of alternatives.
In this talk we will first present how specific iOS restrictions complicate reverse engineering but also reduce the number of tools that can be used by software protection. Then, we will list different methods available to detect jailbreak. Finally, we will describe how to study and bypass a real-world anti-jailbreak solution with the famous opensource dynamic instrumentation framework Frida.
