Hatstack is a group of Fontys students interested in digital security. We meet every Thursday afternoon and frequently participate in hacking competitions (CTFs). Sometimes we find vulnerable stuff, hack it, and tell each other how it was done. Other times we hold a competition ourselves, like during open days or on the Hatstack Village at NEXT.

Scroll down for:


Thursdays from 1500 at Fontys Eindhoven, R1, room 3.21: (51.4517033,5.482314159265,31.5).
