02 Aug 2016

iOS jailbreaks are incredibly useful to security researchers, providing unrestricted access to application and operating system functionality. But with the latest jailbreaks comes a certain amount to of uncertainty. How much can you trust a binary that contains a 0-day kernel exploit? This blog takes a closer look at the Pangu 9.3 jailbreak, specifically focusing on the encryption mechanism that has been used to encrypt strings within the application. We provide a detailed summary of the reverse engineering of this encryption using a mixture of static and off device dynamic analysis.
