It’s happening! Ian Beer has just released a very valuable exploit for iOS 11.1.2. Here’s all you need to know about it.

Powerful kernel exploit for iOS 11.1.2

Google Project Zero hacker, Ian Beer, has stayed true to his word and just released an exploit for iOS 11.1.2.

This exploit is based on the exact same vulnerability Team Pangu disclosed a while back. Incidentally, Siguza’s v0rtex exploit is also based on the same vulnerability in the UaF port.

According to Team Pangu, Apple patched this bug in iOS 11.2 and above versions. This explains why this Ian Beer’s exploit works only up till iOS 11.1.2.

Apart from the exploit, Beer has also released a tfp0 patch and a Proof-of-Concept Kernel Debugger.

Compatibility

Ian Beer has confirmed tfp0 support for all Apple devices on his official Twitter handle just a few minutes ago.

The P0C kernel debugger will work on all devices including the latest iPhone 7 and iPhone 7 plus. Here’s what he wrote on Twitter.

I wasn’t able to ascertain if this even works on iPhone X and iPhone 8 and iPhone 8 plus. If you are on a new device, just make sure it remains in the compatible firmware range.

As far as firmware support goes, iOS 11.1=11.1.2 share the same kernel so this exploit works for versions in this range. Here’s what this means to the end user.

• If you are on iOS 11.1.2 or below, you are good to go.
• If you are on iOS 11.2, this exploit will be useless.

Is an iOS 11 jailbreak dropping soon?

I have said this before and I will say it again – exploits do not equal a jailbreak.

Even though this exploit gets us kernel read/write access, it’s still a far cry from a full-blown jailbreak. The most important of modern jailbreak tools, the KPP Bypass, is still missing.

The best you could do right now is downgrade your iPhone, iPad, or iPod to iOS 11.1.2 or below. Apple won’t be keeping the signing window of these versions much longer so make it quick.

If you are on iOS 11.1.2 and don’t know how to downgrade, simply download the 11.1.2 IPSW file and use Shift+Update in iTunes. That’s all there’s to it. All your data from the previous version (iOS 11.2) will easily carry over.

Are you excited about an iOS 11 jailbreak? I know I am!
