On Thursday, hacker and unc0ver lead developer Pwn20wnd has released unc0ver v2.2.3 to the general public and revised the unc0ver v3.0.0 pre-release to beta 7 with various improvements for the public testing base.
Pwn20wnd announced both
updates via Twitter just this morning, adding that the tool remains
open-source throughout its continued development:
Citing the changelog published on Pwn20wnd’s GitHub page, the unc0ver v2.2.3 public release incorporates the following changes:
01/31/2019 – v2.2.3 was released for public testing with the following changes:
– Fix a bug with extracting rsync
This update is recommended for all users, as it’s a stable public release and contains the latest bug fixes and improvements. If you’re using an earlier version of unc0ver, then you can download v2.2.3 from Pwn20wnd’s GitHub repository.
In addition the new public release, Pwn20wnd has issued four more revisions to the unc0ver v3.3.0 pre-release since our last coverage. According to the changelog, beta 5, beta 6, beta 7, and beta 8 encompass the following changes:
01/30/2019 – v3.0.0~b5 was released for public testing with the following changes:
– Fix a bug with extracting rsync
01/30/2019 – v3.0.0~b6 was released for public testing with the following changes:
– Fix the voucher_swap exploit for the iPhone Plus and X models
01/31/2019 – v3.0.0~b7 was released for public testing with the following changes:
– Fix and enable voucher_swap exploit for iPad Air 2
01/31/2019 – v3.0.0~b8 was released for public testing with the following changes:
– Fix a possible infinite loop for iOS 11.1 and voucher-swap exploit
– Fix a bootstrap error related to libapt/apt7
Notably, unc0ver v3.0.0 doesn’t utilize tihmstar’s new v1ntex exploit, but instead relies on an improved version of Brandon Azad’s voucher_swap exploit to achieve a jailbreak on iOS 11.4.x.
At the time of this writing, unc0ver v3.0.0 supports all 16K devices (A8X/A9/A9X/A10X/A11); the iPad Air 2 is the only supported 4K device at this time. The limitation seems to be related to the amount of RAM that certain 4K devices have, and Pwn20wnd is attempting to resolve this as he continues to refine the voucher_swap exploit.
The unc0ver v3.0.0 is still in beta, which means it’s prone
to bugs. You should refrain from using the beta unless you’re an advanced
jailbreaker or developer and understand the basics of troubleshooting jailbreak
errors. The best course of action is to wait for the official public release
and use unc0ver v2.2.3 in the interim.
If you meet the criteria above and want to proceed anyway, then you can download the unc0ver v3.0.0 pre-release from Pwn20wnd’s GitHub repository.
