Just a couple of days ago, security researcher Brandon Azad released his voucher_swap exploit for 16K devices (A9[X], A10[X], A11[X]), but the exploit didn’t support 4K devices (A7[X], A8[X]), resulting in some devices being unsupported by the recent updates to the Electra and unc0ver jailbreaks.

On a more positive note, hacking guru tihmstar seems to have a solution. Thursday morning, he Tweeted his version of the voucher_swap exploit, subtly named v1ntex. Astonishingly, the exploit supports 4K devices, whereas Brandon Azad’s exploit did not:

But as it would seem, there’s still more work to be done.

Pwn20wnd shared a Tweet Sunday morning denoting how he’s “actively implementing user requests” to make unc0ver “even better.” The Tweet points to the hacker’s official GitHub repository, where unc0ver users can reach out about problems and feature requests via the Issues tab on the web page:

Last chance to downgrade to iOS 12.1.1 as S0rryMyBad publishes details about iOS 12-centric kernel exploit

Anthony Bouchard ∙ January 23, 2019

Apple officially dropped iOS 12.1.3 on Tuesday, and it wasn’t long after that security researcher @S0rryMyBad Tweeted a proof of concept (PoC) of the bug used to achieve an iOS 12 jailbreak at the TianfuCup PWN Contest last November.

On Wednesday, @S0rryMyBad followed up with the PoC he Tweeted by publishing a detailed blog post elaborating the ins and outs of his bug, including how it works and how to use it on iOS 12.1.2 and below:

S0rryMyBad shares PoC of the bug he used to jailbreak iOS 12 on pre-A12 devices

Anthony Bouchard ∙ January 22, 2019

Just over two weeks ago, security researcher @S0rryMyBad announced the discovery of an exploit for iOS 12.1.2 and below for pre-A12 devices, adding that he would release information about it after Apple patched it in a software update. Fortunately, that time has finally come.

Several hours after Apple released iOS 12.1.3 to the public on Tuesday, @S0rryMyBad made good on his promise by Tweeting a proof of concept screenshot of the bug that he had teased earlier in the month:

Pwn20wnd revises unc0ver v2.2.0 pre-release again with more bug fixes and improvements

Anthony Bouchard ∙ January 22, 2019

Hacker and unc0ver lead developer Pwn20wnd revised the unc0ver v2.2.0 pre-release again on Tuesday with additional bug fixes and improvements.

Citing the changelog published on Pwn20wnd’s official GitHub page, what is now the fifth pre-release beta of this particular unc0ver jailbreak tool version comprises of the following changes:

01/22/2019 - v2.2.0~b5 was released for public testing with the following changes:

- Fix theoretical bugs

- Improve assertion to make it safer

- Fix a bug in logging

- Update bootstrap

- Enable overwriting files in the bootstrap extractor

Just like the pre-release revisions that we reported about yesterday, this revision is still a beta and should not be deployed on daily driver handsets. This release is only intended for experienced jailbreakers or developers with knowledge of the troubleshooting steps required to handle potential bugs and instabilities.

Given how long the unc0ver v2.2.0 pre-release has been in its beta stages thus far, we expect that an official public release will follow in the coming days; of course, only time will tell.

If you aren’t comfortable using a pre-release version of unc0ver, then we advise you to use the latest official public release (v2.1.3) instead; it too can be downloaded from Pwn20wnd’s official GitHub repository.

Unc0ver is a semi-tethered jailbreak just like Electra, which means you must re-run the tool after every reboot. That aside, it bundles a newer iOS 11-optimized build of Cydia that sports the official seal of approval from Saurik himself.

If you’ve never used unc0ver before, and plan to do so now, then you can follow our in-depth tutorial about how to install and run the unc0ver jailbreak. The unc0ver jailbreak tool supports all devices that can run iOS 11.0-11.4 beta 3. If you run into any problems while using unc0ver, then you can report bugs here.
