Why iOS 5 Is An Exploitation Nightmare? I0n1c Publishes His CanSecWest Presentation
Jailbreaking has been around from early days of iPhone first it was done through hardware modification then a more sophisticated software method came in. With the passage of time Apple made their iOS mobile operating system more secure and hard to hack (Jailbreak) but developers somehow found the way to bypass Apple’s security and jailbreak almost every iOS update released by Apple. Frequent iOS updated are released to patch the vulnerabilities which are exploited by hackers in order to jailbreak previous iOS version. This cat and mouse chase is still on but Apple is getting clever and intelligently closing doors on iOS hackers. Though jailbreaking is legal but Apple try everything possible to stop it. With iOS 5 Apple changed the game completely and took it to a whole new level. More than 200 new feature we introduced in iOS 5 but the major things which Apple did change completely were at the backend.
Famous iOS security expert and the guy behind iOS 4.x.x untethered jailbreak Stefan Esser recently aka i0n1c gave a presentation at CanSecWest. Stefan explained the difficulties faced by iOS hacker in jailbreaking Apple latest iOS 5 mobile operation system. He also explained the reason behind slow public roll outs of iOS 5 jailbreaks. In this presentation Stefan mentioned that Apple made a great move by snatching “guru of kernel hacking” comex. Remember that Comex was the one who released the first iPad 2 jailbreak in the form of JailbreakMe 3.0. Apple hired comex as a summer intern in their security team. So it was clearly a +1 for Apple and -1 for Jailbreak Community.
If you go through the presentation you’d see how easily Stefan explained the restoration process which Apple completely revamped in iOS 5. Even an average Joe can easily understand the complete process of iOS firmware restoration and how it evolved in iOS 4.x.x and iOS 5.
He also pin pointed some important things about iOS 5.0.1′s untethered jailbreak which was released for A4 and A5 devices. Overall its a good read for jailbreaks and all developer who want to learn about iOS jailbreak and ASLR security. Head over to this link for complete presentation.
