Earlier this week, we saw Jake James release rootlessJB, an SSH-based developer oriented iOS 12.1.2 – iOS 12 jailbreak. It was not particularly a useful jailbreak since it did not support tweaks or code injection of any kind. Thanks to rapid development from James though, rootlessJB has now been updated to support Cydia tweaks.

SSH-based iOS 12.1.2 – iOS 12 Jailbreak RootlessJB 3.1 Released With Ability to Install Cydia Tweaks
The last few days have been quite eventful for the jailbreak community. We got two iOS 11.4.1 jailbreaks (Electra and Unc0ver), which makes all versions of the iOS 11 software update jailbreakable. Security Researchers and hackers have also released an exploit for iOS 12 – iOS 12.1.2 and developer only iOS 12.1.2 – iOS 12 jailbreak.
Following the release of a developer-only jailbreak for iOS 12 by GeoSn0w, Jake James has released rootlessJB 3.0 with iOS 12 support. Right now, rootlessJB supports A9-A11 devices running iOS 12 – iOS 12.1.2. This means Apple’s latest iPhones powered by its A12 Bionic chip including the iPhone XS and iPhone XR are not supported by it.
Over the last few weeks, quite a few iOS 12 exploits have been detailed raising hopes of a possible iOS 12 jailbreak. Ian Beer of Google’s Project Zero team has now published another new iOS 12 exploit.
Security researcher Brandon Azad has released an exploit for iPhones and iPads iOS 12 – iOS 12.1.2. The voucher_swap exploit can be used to build a fake kernel task port which gives one the ability to read and write arbitrary kernel memory.
An updated version of futurestore has been released that is compatible with Face ID-equipped iPhones like the iPhone X, iPhone XS, and iPhone XR. Previously, one could not use futurestore to downgrade back to an unsigned iOS firmware as it would break Face ID.
Since November last year, we have seen Chinese security researchers show off an iOS 12 exploit but they never got around to detailing it or releasing it to the public. Today though, Qixun Zhao of the Qihoo 360 Vulcan team has provided a detailed write-up of his Chaos PoC paving the way for a possible iOS 12 jailbreak on pre-A12 devices
Chinese security researchers Min Zheng and Xialong Bai have taken to Twitter to show off a POP attack proof on the iPhone XS Max running iOS 12.1.2. Min Zheng had earlier showcased a similar security exploit but that was only applicable on an iPhone 6s.
