We need legislation on sideloading ASAP. Yesterday, I learned the hard way that I’m not allowed to use my own personal, paid developer certificate to sign IPAs I want to install on my own personal device. Wow. 😬

After 9 years of having a jailbreak on my main device, today I'm finally making the switch to a stock device…

The end of an era…

Anyone wondered what it takes to get a deterministic kernel exploit on A9? Getting code execution on a coprocessor, of course!

Trigon: exploiting coprocessors for fun and for profit (part 2)

Where did we leave off? Background: KTRR IORVBAR Coprocessors Always-On Processor Investigation AXI? What’s that?! Mapping DRAM Code execution Improving the strategy What about A7 and A8(X)? Conclusion

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.

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

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.
