I designed a passwordless recovery protocol using trusted friends and a server-side second factor for my privacy-focused messaging app twonly.

I wrote a seminar paper on binary rewriting, which allows the modification of compiled binary files without source code, enabling use cases such as fuzzing or hardening proprietary binary files.

This blog post introduces my new generic approach to easily create a fast and easy-to use protocol fuzzer for custom targets.

twonly is a European open-source alternative to Snapchat, written in Flutter.

This winter semester I took part in the TU Darmstadt Hacker Contest, where we had an exercise in which we had to find security vulnerabilities in open source repositories.

In my term paper about the "Internet of Vulnerable Things" I wanted to find a memory-related vulnerability in a binary running on the TL-WR902AC but was not successful.

To learn Rust and cryptography at the same time I implemented the TLSv1.3 from scratch.
