iOS jailbreak scene rising back from the dead – Houdini released and iOS 10.3.3 and 11.1.2 hacks on the horizon
While I don’t usually write about jailbreaking, I think an exception can be made for this article. In a span of under 3 days, the iOS hacking scene went from almost silent (with the last mostly stable and working JB being for iOS 10.2) to teeming with life and hope. The aim of this article is to bring you up to speed in the most concise manner possible 🙂
iOS 11.1.2 tfp0 exploit is on the horizon
On Wednesday, Ian Beer, a well-known computer security researcher and Project Zero member created a new Twitter account to share some important news with us all.
He seems to have found an exploit that works on (all?) iOS devices that are on iOS 11.1.2 or lower. The exploit allows code to be run with kernel privilages so it has the highest privilages possible. Ian Beer plans to release his work on the tfp0 (task at pid 0) exploit which according to Redditors is about 80% of a jailbreak. This means that with some work from other people, a full jailbreak on iOS 11.1.2 may land soon! Just don’t update to iOS 11.2 if you want a jailbreak, if you’re on 11.2, you may downgrade without restoring by reading the instructions in the link below!
iOS 10.3.3 (included) and lower exploit by Siguza
Siguza, who had a huge part in getting us Phoenix (iOS 9.3.5 jailbreak for A5/A6 devices) has released his work on the v0rtex exploit.
His current work gets code to run with root permisisons on all versions of iOS lower than 10.3.3 (included). Apparently, this exploit only works on A7-A9 devices but with some work, it could be made to work on 32-bit (Apple A6) devices too. According to some Redditors, this can be considered as 60% of a jailbreak because more work needs to be done (such as tfp0) but there’s still hope.
If a jailbreak comes out of this, 32-bit devices including A6 ones (iPhone 5/5C and iPad 4) will be jailbroken forever as iOS 10.3.3 is the last version for A6 devices! Some A7 devices (every device bar the iPad Mini 3 and late iPad Mini 2s) can be downgraded/upgraded to iOS 10.3.3 via OTA so when a method to do this comes out, this potential jailbreak will be also useable on these devices!
Houdini has been released for iOS 10.3.2 and below
Houdini is not a full jailbreak but it allows some jailbreak-esque functionality to be had on devices running iOS 10.3.2 and below (mostly useful for 10.2.1 (Saïgon takes ages to work) to 10.3.2 – 64 bit devices only). Some of its features are:
- Theming user-installed applications
- Clearing app cache (great way to regain some space)
- Changing the display’s resolution
- More theming options and tweaks
This program is by Abraham Masri (@cheesecakeufo) and I suggest you install it if you’re on iOS 10.2.1 to 10.3.2 since it’s the only way to get some jailbreak functionality on those versions. You may think of Houdini as an alternative to Cydia that mostly focuses on themes along with some functionality of iCleaner Pro.
