iOS 5: An Exploitation Nightmare?

I0n1c (Stefan Esser), the hacker behind the iOS 4.3.1 untether, has posted his presentation slides from CanSecWest.

The talk focused on iOS 5 and the more than 200 new features and changes it brought. Some of them had a security impact causing the release of a public jailbreak to seemingly take forever.

I0n1c notes that the release of a jailbreak was slowed down due to Apple snatching the scene's 'biggest iOS kernel guru' comex. In addition, the company also killed several bugs in iOS 5 that jailbreak developers relied on and made changes to the iOS 5 restore process that required more reverse engineering and required a more strategic vulnerability release. Furthermore, new devices like the iPad 2 and iPhone 4S could not be exploited using the bootrom vulnerability exploited by limera1n.
