Hi there


My name is Marco Squarcina, I'm a postdoctoral researcher in the Research Unit Security and Privacy at TU Wien. My research interests focus mainly on Web and mobile security, but I'm passionate about computer security and hacking in its broadest sense. I love teaching, and I strongly support the concept of learning by doing. I play and organise CTF competitions with w0y and mhackeroni with whom I competed 3 times at the finals of DEF CON CTF. I co-organized the Italian Cyber Challenge project, trained Team Europe for the International Cybersecurity Challenge (ICC 2022), and coordinated the largest Attack/Defense CTF in the history of the European Cybersecurity Challenge (ECSC 2022) by the European Union Agency for Cybersecurity (ENISA).

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.
