Write-ups and blog posts

I’m a 19-year-old iOS security researcher from the UK. What started out as a hobby at 15 years old has become my full-time job, with me now being an iOS researcher at Cellebrite Labs. However, before that started, I enjoyed maintaining my blog and releasing public projects - and I still do today! While I may not do so as frequently anymore (I have far less free time than when I was in school), I try my best to make time for some of my more exciting external projects when I can.

I’ve written about various components of iOS - code-signing, kernel exploitation and PPL & SPTM to name a few. As part of these, I also delve into untethered code execution, attacking coprocessors and pushing both the hardware and the software inside these devices to the limit.

Projects

Project What it is
Trigon Deterministic kernel exploit for iOS 16.5.1 and below
Titan PPL & SPTM bypass for iOS 17.3.1 and below
ChOma CoreTrust bypass for iOS 17.0 and below
Achilles checkm8 implementation and PongoOS booter
TrollInstallerX TrollStore installer for (almost) all TrollStore-supported devices
KextRW macOS kernel extension for vulnerability research on current macOS

Not everything gets released. I’ve also worked on an untethered jailbreak for iOS 14 and several kernel PAC bypasses. There are always future projects and write-ups in the works, so stay tuned! I will always announce new blog posts on my social media accounts, listed below.
