Comex has just confirmed via a series of tweets that his userland jailbreak he already showed off few days ago has already been patched by Apple in the newly released iOS 4.3.1. Well, hackers lose the war against Apple again.
Comex on his Twitter account:
yeah, uh. I can find kernel exploits, but this is ridiculous.
As noticed by @0naj, my kernel exploit was fixed in 4.3.1.
I try not to be paranoid, but it is really hard to explain this as anything but a leak.
It stayed there from 4.0.2 through 4.3, but was magically found in time for 4.3.1. well, go go @MuscleNerd and @i0n1c I guess
Interestingly, and as Comex notes, “is that my “new” kernel exploit is actually the kernel exploit used by JailbreakMe 2.0. It was never properly fixed.”
Now the only hope is from the iPhone hacker Stefan Esser who is the only one having untethered exploit right now which jailbreaks all iOS devices on iOS 4.3.1 except iPad 2. Yes, MuscleNerd and Stefan must find more exploits to jailbreak the iPad 2. [Twitter: 1,2,3,4]
Comex, the well-know iPhone hacker, and the guy behind Spirit and JailbreakMe, has unveiled some good news for iPad 2 users, as we reported you earlier that Comex has successfully jailbroke iPad 2 running iOS 4.3 with his upcoming userland jailbreak, today he just confirmed that there’s new bootom exploit has been discovered by someone to jailbreak iPad 2 running iOS 4.3.
Someone asking Comex: is your new iPad 2 exploit in the boot rom? Or a userland exploit? Kinda curious. I am one of the lucky ones who landed one day one.
Comex replying: Userland, but I hear someone has a bootrom vulnerability that they might have exploited.
Comex didn’t announce about the hacker who have this bootrom exploit. On the other hand you have to know that also Stefan Essar (iPhone hacker) also has confirmed that he will release his untethered iPad 2 jailbreak on iOS 4.3 by the next weekend.
It’s highly expected that hacker behind this exploit will keep his bootrom exploit until iPhone 5 releases to make it effective for the longest period as much as they can, as this kind of exploits is only patched by a hardware upgrade. But the userland exploit is a software exploit which can be patched on any iOS update.
Confirmed: limera1n is patched in iPad 2.
For who don’t know, all current jailbreak tools are based on Geohot’s boot room exploit (hardware exploit), so Apple was able to patch this exploit by upgrading iPad 2 hardware.
So we’ll not be able to jailbreak iPad 2 with any of the current jailbreak tools. But really I trust that hackers will be able to handle this issue soon.
