What good news this week on the underground scene of iOS! Yesterday, two jailbreak tools (Electra and unc0ver) have been updated to support iOS 11.4.x. Later that day, developer and hacker Geosn0w announced the release of an iOS 12.0 to iOS 12.1.2 jailbreak called OsirisJailbreak12.
OsirisJailbreak12 uses the security vulnerability CVE-2019-6225 that Apple corrected in iOS 12.1.3 released earlier in January. Note that this jailbreak of iOS 12 is currently incomplete and reserved for developers at first. This unlocking was, among other things, made possible thanks to the tfp0 exploit recently revealed by security researcher Brandon Azad.
To be perfectly clear, OsirisJailbreak12 is not intended for the general public and therefore it does not allow you to get Cydia once it is deployed on your iDevice. It is only intended for developers for testing purposes. Geosn0w invites them to take advantage of the tool as they please, as long as they respect the associated copyright license.
This iOS 12 jailbreak via OsirisJailbreak12 is compatible with iPhone 6s, 6s Plus, 7, 7 Plus, 8, 8 Plus, as well as iPhone X, XS, XS Max and XR. If you are under the latest major version of Apple’s mobile operating system and you are impatiently awaiting a jailbreak, we advise you to stay on iOS 12.1.2 (or to downgrade the firmware via iTunes if you have already installed iOS 12.1.3). At the time of writing, this version of iOS is still signed by Apple.
For those who wish to participate in the OsirisJailbreak12 adventure and help publicize the first iOS 12 jailbreak for compatible iPhone, iPad and iPod Touch, you can install the IPA file Osiris12JB.ipa (using Cydia Impactor on your computer) in you returning to this address.
