I am an exploit developer/penetration tester for Maroon Penetration Testing based in Oklahoma (private organization) and I am currently looking for vulnerabilities in iOS, but I would either need the source code of iOS or the system files (root or / directory). I am running iOS 10.2.1 and it is nearly impossible to jailbreak the device, downgrading is not an option either. If there is anywhere I can download the source of iOS 10.2.1/ the root directory contents that would be awesome, or if there is any way to retrieve them myself that would be even better.
Regards, Noodles.
