Pwn20wnd touts notable progress on iOS 13.3 support in unc0ver jailbreak

Anthony Bouchard ∙ February 8, 2020

If you’re avidly following the latest developments in the jailbreak community as of late, then you might be excited to learn that hacker and unc0ver lead developer Pwn20wnd has made swift and substantial progress on implementing Brandon Azad’s newly-released oob_timestamp tfp0 exploit for iOS 13.3 into the unc0ver jailbreak.

Throughout the past hour, Pwn20wnd has shared a plethora of status updates regarding his progress. Perhaps one of Pwn20wnd’s most notable Tweets was that he had successfully bypassed the mitigations in place by Apple to trump his codesigning bypass, which is claimed to be “the biggest part of the jailbreak on A12(X),” and apparently, on A13 too:

Complications and progress as Pwn20wnd tests the new oob_timestamp exploit

Anthony Bouchard ∙ February 8, 2020

The release of Brandon Azad’s oob_timestamp exploit yesterday afternoon meant that Pwn20wnd could finally get to work on adopting support for the unc0ver jailbreak. On the other hand, a plethora of Tweets shared early Saturday morning suggest that doing so could be a lot more work than initially thought.

While Pwn20wnd has every intention of updating the unc0ver jailbreak to support iOS 13.3 on A12(X)-A13 as planned, it seems that the biggest complication would be the impractical amount of work needed to support each and every individual firmware version between iOS 13.0 and 13.3 on each and every device type:

Brandon Azad officially releases OOB Timestamp exploit for iOS 13.0-13.3

Anthony Bouchard ∙ February 7, 2020

Several days ago, hacker and iOS security researcher Brandon Azad took the jailbreak community by storm when he said he would soon be releasing a new kernel exploit proof-of-concept targeting the iPhone 11 on iOS 13.3. It didn’t take long after that for unc0ver jailbreak lead developer Pwn20wnd to add that unc0ver would likely receive an update incorporating the new exploit.

The teasers have awakened a brand-new audience in the jailbreak community, namely those handling Apple’s latest handsets like the iPhone 11 and variants of the iPhone 11 Pro. But all that hype aside, Azad officially released his new kernel exploit proof of concept Friday afternoon, and he’s calling it OOB Timestamp:

Brandon Azad plans to release a new exploit for iPhone 11 on iOS 13.3

Anthony Bouchard ∙ February 4, 2020

Avid jailbreakers sporting any of Apple’s latest A13-equipped handsets have yet to see any official jailbreak solutions for their particular devices. But could that change in the foreseeable future?

Hacker and iOS security researcher Brandon Azad took to Twitter Tuesday afternoon to announce an exceptional tidbit of news – namely that he would release a proof-of-concept exploit that can achieve read/write on an iPhone 11 running iOS 13.3:

Hacker iBSparkes achieves tfp0 on A13 with iOS 13.3

Anthony Bouchard ∙ December 22, 2019

The jailbreak community has been on fire these past few months, with checkra1n delivering an un-patchable jailbreak experience for handsets ranging from the iPhone 5s to the iPhone X, and with unc0ver picking up support for iOS 12.4.1. But hey, why let the pwnage stop there?

Renowned hacker and iOS security researcher iBSparkes broke the silence this weekend after sharing a teaser of what appears to be successful tfp0 on a brand-new A13 device running iOS 13.3. Yes indeed folks, that’s both Apple’s latest hardware and software – pwned in one fell swoop. Not too shabby!

Newly teased tfp0 bug supports iOS 13.3 and A12/A13 devices

Matrix code hacked iPhone.

It’s always exciting for the jailbreak community when someone comes forward with a brand-new bug that could potentially enable exploitation for jailbreaking newer devices and versions of iOS. After all, Apple tries very hard to keep iOS bug-free and quickly patches anything that even smells jailbreakable.

With that in mind, a newly-teased ‘tfp0’ bug shared first by @08Tc3wBB and later validated by security researcher @RazMashat would appear to be compatible with Apple’s latest and greatest iOS 13.3 firmware on handsets up to and including the A13 variety. Indeed; even the iPhone 11 Pro platform seems to be vulnerable:

Downgrades from iOS 13.3 no longer possible as Apple unsigns iOS 13.2.3

Anthony Bouchard ∙ December 19, 2019

Apple stopped signing iOS 13.2.3 Thursday evening, barely over a week after releasing iOS 13.3 to the general public. It’s an expectable move on the company’s behalf that prevents iPhone and iPad users from restoring to that particular firmware version, or from downgrading from the newer iOS 13.3 release.

Apple’s official reasoning for doing this is to facilitate software upgrades to ensure that users take advantage of the latest features, bug fixes, and security patches. Behind that marketing façade, it’s also evident that Apple prevents software downgrades in an effort to keep the jailbreak community at bay, as most jailbreak tools only operate on older versions of iOS, and Apple quickly patches these jailbreaks in its software updates.

iOS 13.3 restores the ability to keep a trimmed clip alongside the original video

Christian Zibreg ∙ December 10, 2019

The iOS 13.3 software update that dropped today brought a bunch of bug fixes to iPhones and iPads around the world along with new features like Screen Time Communication Limits, a handy Memoji Stickers toggle for the stock keyboard and more. But there's one particular feature that we'd like to highlight because Apple has tucked it away as a side-note in the bug-fixes section of the iOS 13.3 changelog. I'm talking about trimming videos in Photos.
