Absinthe 2.0 jailbreaks most iDevices running iOS 5.1.1

post #1 of 94
Thread Starter 
The untethered jailbreak Absinthe v2.0 debuted on Friday with compatibility for almost all devices powered by Apple's A4 and A5 processors running the latest iOS 5.1.1 firmware, and is the first solution to unlock the new iPad.

Disclaimer: Jailbreaking may void Apple's warranty and in rare cases cause damage to the device being unlocked. Users opting to run jailbreak software and tweaks do so at their own risk.

Announced at the Hack in the Box event in Amsterdam, GreenPois0n Absinthe v2.0 is the result of a collaboration between the Chronic-Dev Team and iPhone Dev Team and gives iDevice users wider access to system features normally prohibited by Apple thus allowing for the download of applications and extensions unavailable in the official App Store.

Currently, the iOS 5.1.1-only jailbreak can be applied to nearly all iPads, the iPhone 3G, 4 and 4S, third and fourth generation iPod touch media players, and the second-generation Apple TV. Support for the new 8GB iPad 2, which features a custom-designed A5 chip, will be available soon though the team notes that Apple TV compatibility will not be included in the version 2.0 build.

Absinthe v2.0


During the event, the "dream team" of hackers explained (via iClarified) how Absinthe v2.0 works:

GreenPois0n Absinthe was built upon @pod2g's Corona untether jailbreak to create the first public jailbreak for the iPhone 4S and iPad 2 on for the 5.0.1 firmware. In this paper, we present a chain of multiple exploits to accomplish sandbox breakout, kernel unsigned code injection and execution that result in a fully-featured and untethered jailbreak.

Corona is an acronym (sic) for "racoon", which is the primary victim for this attack. A format string vulnerability was located in racoon's error handling routines, allowing the researchers to write arbitrary data to racoon's stack, one byte at a time, if they can control racoon's configuration file. Using this technique researchers were able to build a ROP payload on racoon's stack to mount a rogue HFS volume that injects code at the kernel level and patch its code-signing routines.

The original Corona untether exploit made use of the LimeRa1n bootrom exploit as an injection vector, to allow developers to disable ASLR and sandboxing, and call racoon with a custom configuration script. This however left it unusable for newer A5 devices like the iPad2 and iPhone 4S, which weren't exploitable to LimeRa1n, so another injection vector was needed.


Basically, the jailbreak takes advantage of certain exploits found in iOS to gain higher levels of systems access to "breakout" of the Apple-imposed sandboxing, or the iPad maker's stringent set of operating rules for apps running on the device. For example, jailbreaking gives apps the power to change certain system settings, like Wi-Fi or Bluetooth, on or off.

Friday's announcement saw such high levels of interest that the Cydia app store became overloaded with a flood of new users.

The intricacy of some of these jailbreak methods is very impressive. There's some clever guys out there... if they have any interest in working for Apple then Apple would do well to snap them up.

The only reason I'm jailbreaking my iPad is to install XBMC.

Ho hum... this might be good news for some, bad news for some developers, but meh for me.  I have no desire to jailbreak.

That would be a brilliant move. Apple hires the best jailbreakers and gives them the next iOS in advance. If they jailbreak it, Apple fixes the hole before release. If they don't, Apple hires the next jailbreakers (who are better, having managed something the previous guys failed at), and so on ad infinitum...

I jail-broke my 1st GEN iPad and a friends iPhone 4 via RedSn0w.  Was ok and could do certain things like theme the home screen and icons as well as tether the device (hotspot it).  But Apple has made it really appealing to not have any reason to Jailbreak the device.  I might do my iPhone 4s.  The only reason would be to unlock it for another network.

Hurray for SBSettings on my iPhone 4 again.... I'll be jailbreaking that again at the first opportunitity as I've been missing that easy access Bluetooth switch!

 

Won't be doing my iPad (3rd gen) though because as much as I'd love to get xbmc on it the f@#king Sky Go! app I use for watching sports while away from home has jailbreak detection in it and refuses to stream on jailbroken devices "for security reasons"... 

 

Slightly off topic, but I wish they'd get a move on with Seas0npass for the 3rd gen AppleTV as that is crying out for xbmc.... I know, I know, it's not like they are being slow on purpose...

Hmm... I currently use PS3 Media Server to stream (and encode on the fly) movies stored on my iMac to my PS3.

 

The creators of PS3 Media Server have since updated the software to support a range of other media renderers - including XBMC.

 

Am I right in thinking that with Absinthe, I could stream movies direct to an iPad then Airplay to an AppleTV?

 

If this works, I could then get rid of the PS3 and replace it with an AppleTV.

 

Also, I assume I'd have to Jailbreak the AppleTV - would that be correct?

 

Has anyone got this working?

iOS 5 negated a lot of reasons to jailbreak. However, I was still left wanting more. I jailbroke both my new iPad and 4S this morning. Here are my favs:

 

My3G: Allows me to use FaceTime over 3G. Also when I watch youtube videos over 3G they aren't pixelated beyond recognition(because it tricks the phone into thinking you're using wifi).

 

Belfry: It installs the stock weather app, clock app, compass, stocks, voice memos, and calculator app on the iPad(I have no idea why these are only on the iPhone).

 

Springtomize 2: I can delete/hide stock apps that I don't use like newsstand or ibooks

 

SBSettings: Allows me to toggle things like bluetooth, wifi, LTE, etc without having to launch the Settings app(with just a swipe of the finger)

 

SiriSports: Get scores, times, game stats etc just by asking siri.

Update.  I just tried it on my iPhone 4s with iOS 5.1.1 and it worked flawlessly.  Very Nice.

That's a decent list, but one critique: iBooks is not a stock, built in app, it's downloaded from the App Store, so you would be able to delete it without a jailbreak, or never download it at all if you wanted. Although hiding Newsstand and SBSettings are reason alone to jailbreak!

I jailbreak for little things like having the SMS tone I want.

I pretty much agree with you. A while back I snagged a copy of Tether off the app store and thought I wouldn't need to Jailbreak anymore. After getting my new iPad (att version) and turning on the mobile data for a trip to Atlanta, I realized how convienant that is. And holy Moses is that Lte network fast! Anyways I might jailbreak my iPhone so the kids can tether their iPads when we go on our summer vacation. Not to watch YouTube, but just to be able to look up facts and simple things like that while on the road, which feels very liberating. Otherwise I would have no need to Jailbreak*.

*I do realize that there are other reasons people want/need to jailbreak, just talking about me.

All done. SBSettings, Zephyr, FiveIconDock and TetherMe are my main reasons to jailbreak.

I have ONE reason to jailbreak. I was in contract with AT&T for 18 months before I got moved out of the country. We paid TWO $350 cancellation fees for two separate iPhone 3GS'. But the bastards still control my phone because I have to "cheat" to use a product I OWN but is being held hostage. If I could carrier unlock without jb'ing I would. When the iPhone 5 comes out I will be replacing these with a two factory unlocked phones.

Oh, my therapist tells me I'm almost over it. Haha!

We are sincere in our belief that one of the reasons most (92%) people jailbreak is to pirate apps because the evidence is in our favor.

It's more like one of the reasons some people jailbreak is to pirate apps.

I don't consider the App Store a "jail." It's the best software store so far invented. But if it's not enough for you then by all means hack your phone.

Those rotten greedy Mother Frackers. I bought the first iphone used just as the 3G model were announced. Made sure that mobile data was off. Everything was cool for about 8 months until they figured out I had an iPhone without a data plan. Att forced me take a data plan or they were going to shut down my service. I really couldn't afford it at the time but had that number for years so I had no choice. I make damn sure I use at least three gigs of data a month but not more than 5 every single month.

Sometimes it's just about tweaking the phone the way you want it, not about adding new software.

Sure - one of the reasons. But only one, for some people. Some people use knives to stab people, but that isn't a good reason to oppose the manufacture or possession of knives full stop.

When did 92% become "some?"  I clearly state that piracy is only one reason but clearly a very popular reason for the vast majority of jailbreakers.

I would hardly call what you provided as hard evidence just because a couple developers said so. Maybe it's true, maybe it isn't...

That's logically flawed. The fact that 92% of users of a paid jailbreak app pirated it doesn't mean that 92% of jailbreakers are app pirates. For one thing, it's only a single data point. For another, lots of people only use jailbreak tweaks which are free. Those people wouldn't show up in those kind of stats on either side.

 

Anyway: some people like jailbreaking, some people don't. Should we leave it there? I get the feeling all the points in this argument have been made lots of times before.

If Apple would remove all legitimate reasons for jailbreaking by providing the missing functionalities, then only illegitimate reasons for jailbreaking would be left.

That's fine, I believe that some people Jailbreak simply to be able to steal apps. Unfortunately, last time this was being debated the argument was everybody or nearly every jail breaker was a thief. Period. That i do not believe to be true.

Just speculating here, but I guess that in the us most app thieves are college students or younger. Probably don't yet fully understand that they are stealing and that developers are hurt by this theft or why it should matter to them.

For me .99 to $4.99 for good games and utilities is money well spent. Hell the $50 I spent on the Tomtom app for my iPhone was well spent as I got a free upgrade from them when I added it to my iPad. Morals aside, my time is far more valuable to me than spend hours searching out how to steal that $5 game. I would believe that for many (but not all) adults feel the same.

Free jailbreak tweaks are meaningless and have nothing to do with this argument.

 

Other data points would have to come with applications from the App Store AND from the Cydia Store. I'm certain they're out there. While 92% piracy seems like a fringe case, I can assure you that 8% piracy is as well.

Yep it worked for me on first go. I did have the reboot a couple times before Cydia worked properly.

Maybe. The list of legitimate reasons for jailbreaking is pretty vast, though. The only way Apple could cover them all would be to make iOS as customisable as Android. That would come with all the disadvantages of Android, and isn't really what anybody wants. I think jailbreaking will continue to exist as a happy medium.

Can you elaborate as to why they are meaningless? Pulling some figures out of the air, if 90% of jailbreak users only used free tweaks, that would change the face of the piracy argument dramatically, compared to if only 9% of users did. It would imply that a smaller/greater proportion of jailbreakers were pirates, respectively.

How do you know what anybody wants except yourself? You don't speak for me..

 

I want to be able to choose any SMS tone I want and jailbreaking makes this possible but I wish Apple would open up this kind of functionality.
