Hatstack is a group of Fontys students interested in digital security. We meet every Thursday afternoon and frequently participate in hacking competitions (CTFs). We're proud to announce that we've won the Platform voor Informatie Beveiliging CTF twice (2015 and 2016). 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 at Fontys events such as the Hatstack Village at NEXT Week or the Huge Leap Week.

Thursdays from 15:00 at Fontys Eindhoven, R1, room 3.21: (51.4517033,5.482314159265,31.5).

Hacknights are about once a month with talks, pizza and hacking. Hacknights are announced on the members' mailing list and below. Talk to a hatstacker or contact us to get on the mailing list.

There's a CTF running on @ seclab. Will run until next week or until the next hacknight. Depends on how fast things get solved. You can ask for hints on IRC. Keep hints in private messages please to avoid spoiling things.
