Userland Jailbreaks More Difficult Past iOS 4.3?

Jan 26, 2011 by

Everyday, Apple throws new challenges at iPhone hackers and jailbreakers as part of their commitment to keeping their devices closed. For the most part, hackers such as MuscleNerd, Geohot and comex have been able to overcome these challenges. In a recent iOS 4.3 beta, it has been discovered that Apple has added something referred to as ASLR or Address Space Layout Randomization.

Joshua Hill (posixninja) has already expressed his feelings towards this over Twitter.

He then continues by explaining what ASLR is.

ASLR randomizes where the device memory is located from where the code is injected and executed which makes it difficult for hackers to judge the exact memory address of their malicious code.

What this means for future jailbreaks and whether it will affect the latest Greenpois0n untether expoit found by the Chronic Dev Team is unknown, but you can be sure to stay with How’s My App for the latest on this developing story.
