Hi there


My name is Marco Squarcina, I'm a postdoctoral researcher at TU Wien. My research interests focus mainly on web security, but I’m passionate about computer security and hacking in its broadest sense. I love teaching and I'm a strong support of learning by doing. I play and organise CTFs with w0y and mhackeroni. Before relocating to Austria I co-organized the Italian Cyber Challenge project and served as a coach for the national team that competed in the ENISA European Cyber Security Challenge.

The best way to get in touch with me is by e-mail. Please use my PGP key if you need to send sensitive data. You can also reach me by phone at +43 (1) 58801-192607, or in my office at Favoritenstrasse 9-11, Stiege 2, 1. Stock, 1040 Wien.

I'm a jungle/drum'n'bass DJ, still using turntables and carrying around a 30kg record bag. You can find a selection of my old dj sets on mixcloud. More recently I've started streaming on Twitch, follow me if you want to be notified when I go live.
