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.

Me and staturnz have been going to great lengths to try and get a truly deterministic Trigon exploit working for A9. This is one of the more complicated strategies, but it's working pretty nicely! Expect an open-source release and writeup in the future. 💯

Just released a short writeup for the A9 version of the Trigon exploit, which involves getting code execution on a coprocessor before exploiting the kernel - enjoy! alfiecg.uk/2025/07/16/Tri…

Great exploit from staturnz - for those of you who hadn’t realised, this is the same bug used in Trigon, working all the way back to iOS 3!
