My name is Mathias Hall-Andersen, I am a CS student at the University of Copenhagen (“DIKU”). My primary interests are: cryptography, algebra, reverse engineering and anything which lies in the intersection. In my free time I play and organise CTF (“competitive hacking”) competitions together with the Pwnies student organisation.
