My iOS 14 jailbreak for arm64 devices that uses a custom kernel exploit, full physical R/W, trustcache injection and now persistence. Tweaks are loaded at boot, which is super cool!

Update: I integrated landa into the latest commit, which adds supported for the remaining iOS 15 versions. The exploit will now work on all iOS 14 and 15 versions.
Vertex should now work on all devices running iOS 14.0 - 15.7.3.

Finally managed to exploit Trigon on arm64e! Certainly more complicated than arm64, but it uses some cool tricks that certainly make it a really nice exploit. Just like the original, it’s a very quick exploit, and of course deterministic too.

This is unexploitable due to the anti-replay integrity tree, but it's still been a cool project to work on and a great way to learn a bit more about the SEP.

I've just released the slides from my @0x41con talk with @opa334dev - "The State of iOS Jailbreaking in 2025".

The original Trigon release supported only A10(X) devices, so I hope to release the updated version for all arm64 devices in the future.

This uses the same method of untethering as the one I posted a few months ago, but aside from the fact it uses Trigon, the jailbreak in this video is a lot different under-the-hood. It's a lot more stable, quicker and overall a much more well-written jailbreak.

At @0x41con, I talked about how a newer version of Trigon was developed for A7 - A9 and A11 devices. I demoed the following untethered iOS 14 jailbreak, which is 100% reliable on all devices thanks to Trigon - the following video shows it running on an iPhone 6S and an iPhone 7.

A great conference and an even better group of people - couldn’t think of anywhere better to have done my first talks. Thanks @xerub and @justandrijana for all the work done BTS to make this possible!.

There was a lot of work put into this tool and it has turned out great. Free, easy and blackbird-assisted downgrading is now possible on A9 for the first time!.
turdus_merula - a free downgrading tool for A9(X)/A10(X) devices using the SEP exploit developed by @dora2ios, @imnotclarity, and @mineekdev - has released. Download: Guide (when I figure out why build is failing):

@staturnzdev @imnotclarity This is a very powerful primitive, but it’s also a very well mitigated one. There were many failed attempts at different strategies during the development of this exploit. I look forward to seeing how this was exploited on arm64e - it should be very interesting!.
