Today we have shared with the world that we developed a new jailbreak for iOS 7.1.1 by releasing a picture of a jailbroken yellow iPhone 5c at iOS 7.1.1. This jailbreak is a completely reimplemented exploit for an iOS kernel vulnerability that is completely based on an exploitation technique we discuss in our trainings. The discussion of this technique (not this specific vulnerability) was added to our course in March and makes exploitation of this specific kernel bug 99.99% stable. We mainly developed this new exploit in the last days to test the technique in the real world.
You might wonder what is so special about this specific jailbreak. It is the fact that a kernel bug is used that is hidden inside some functionality that can be easily reached even from within the iOS application sandbox. This means that the exploit code can be used to break out of any application that you exploit. This is very different from nearly all of the kernel vulnerabilities used in iOS jailbreaks since iOS 4.
