Ian Beer’s iOS 11.1.2 exploit released and v0rtex exploit (=>iOS 10.3.3) ported to iPhone 7 and 32-bit devices, gets tfp0 access and sandbox escape!
Until a few days ago, the iOS jailbreak seemed like it was almost going to die as there wasn’t much to look forward to. Yet, in a couple of days, thanks to dedicated hackers like Ian Beer and S1guza, the jailbreak scene has come back to life! This article is here to give you all the necessary information in a concise manner without having to dig around /r/jailbreak and other sites.
Ian Beer releases his iOS 11.1.2 exploit that gives tfp0 access
Less than a week ago, Ian Beer tweeted on his newly-created Twitter account that he had an exploit for iOS 11.1.2 (which was patched on iOS 11.2) that granted the user tfp0 access. Tfp0 (task at pid 0) is said to be about 80% of a jailbreak as it gives the user the ability to run code with kernel privileges (the highest privilege code can be run at).
Now, Ian Beer released his exploit to the public so that other talented developers could develop it further so that a full jailbreak or some type of hack becomes available for the general public. Lately, Jonathan Levin (@Morpehus______) seems to have become quite interested in exploiting iOS 11.1.2 so maybe he’s on to something! He’s also mentioned that the Apple TV has a good chance of getting pwned as he wishes to update LiberTV to work on tvOS 11.x since Ian Beer’s exploit works on tvOS 11.x (versions based on iOS 11.1.2 or lower) as well! If you want a jailbreak, you should really downgrade to iOS 11.1.2 if you’re on iOS 11.2.
v0rtex now works on 32-bit devices, gets tfp0 access and can escape sandbox
S1guza has developed his v0rtex further so that it has tfp0 access and can escape sandbox which means that a jailbreak is even closer than before!
Apart from this, the v0rtex exploit now supports Apple A10 (presumably A10X devices too?) which means that the iPhone 7 (+) stands a good chance of getting jailbroken on iOS 10.3.3 (or below) soon!
Tihmstar (massive contributor to Phoenix and creator of Etason JB among other feats) has got v0rtex (presumably with s1guza) to work on Apple A6 (32-bit) devices. This means that the iPhone 5/5C and the iPad 4 will probably be jailbroken for life pretty soon!
If you wish to read more about these recent updates, visit the links below. Make sure to downgrade to iOS 11.2 from iOS 11.1.2 while it’s still being signed (probably won’t be signed for too long) and stay on iOS 10.3.x if you want a jailbreak! As always, don’t ask for ETAs!
