I’ve never before: done ROP, played with IOKit, MIG or the kernel heap, etc, etc. Note: This project included a lot of “firsts” for me. how the UaF can be used to gain PC control.The following are assumed to be well known/understood, and are explained in detail in his writeup: Now, If you haven’t already, I heavily suggest reading jndok’s writeup before continuing here.

I’m gonna leave it at applying the tfp0 patch here, but turning this into a full jailbreak should then be as “simple” as installing more patches to the kernel and other parts of the system, using tfp0 + the Mach APIs… it’s just gonna be a whole lot of work.

So, here’s my demonstration of how to use the Pegasus vulnerabilities to dump, exploit and patch an iOS kernel in a way that can be done from within the sandbox and with only publicly available knowledge (i.e. In light of that, I’m going to release my tool in an unfinished state and instead focus on this writeup. Of course huge props to all of them, but that kind of abolishes the need for an iOS 9 tfp0 patch. And on December 15th Ian Beer killed it (once again) with his partial 10.1.1 jailbreak, which qwertyoruiopz is now turning into a full one, probably diverting everyone’s attention away from iOS 9 for good. Apparently I’ve also missed some ongoing efforts by Simone Ferrini/ Benjamin Randazzo/ to create a 32-bit jailbreak based on these vulnerabilities. I intended to bring it to full compatibility with as many devices and OS versions as possible, but shortly after my PoC, released a web-based reimplementation of the 9.2-9.3.3 jailbreak, which does have a tfp0 patch. On December 4th, my tool had advanced enough for me to release a proof of concept video, it was still far from complete. Shortly after that I started working on a tool to exploit them on iOS, in order to add the tfp0 kernel patch that has been missing from Pangu’s 9.0 and 9.2-9.3.3 jailbreaks. On October 4th, did an amazing writeup on how to exploit the Pegasus vulnerabilities on OS X.
