I'm an iOS hacker / security researcher from Switzerland.
I spend my time reverse engineering Apple's code, tearing apart security mitigations, writing exploits for vulnerabilities, or building tools that help me with that. Sometimes I speak about it at conferences, sometimes I do lengthy blog posts with all the technical details, sometimes my work becomes part of a jailbreak, and sometimes it never sees the light of day.

Biggest project I've ever been a part of, and by far the best team I've ever worked with.
Hack DifferentA Discord server about all kinds of hacking, reversing and developing on and around Apple platforms. Relaxed atmosphere, plenty of cool people to hang out with. No tech support.

I'm not an active developer there, but I wrote the kernel exploit for iOS 13.0-13.5.
