Earlier this month, Apple unveiled iOS 12 and proceeded to release the first developer beta of the OS. The release is primarily meant for developers but then that has not stopped developers and researchers from prodding into the OS and finding vulnerabilities for it. Security researcher Liang Chen of KeenLab has done has done exactly that and managed to jailbreak iOS 12 running on his iPhone X.
He has also posted a video of the jailbreak where he first gives a visual proof that his iPhone X is indeed running iOS 12 and then proceeds to launch the KeenLab jailbreak app which installs Cydia on his jailbroken iPhone X.
This is the first iOS 12 jailbreak demoed by any security researcher. It is unlikely that we will see Chen release the exploit behind this exploit since the KeenLab team is known to keep such exploits private for their own research and testing purposes. And irrespective of whether the exploit is released to the public or not, there’s a remote possibility that Apple could end up fixing it before it releases the final build of iOS 12 to the public in September.
Nonetheless, the jailbreak proves that there’s still a possibility of a potential iOS 12 jailbreak being released when the final build of the OS drops later this year.
