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.
