In 2014 some infosec interested students at TU Graz started playing CTFs under the name LosFuzzys. In the last year, thanks to stefan and a couple of other very motivated guys, we managed to get more people interested and the whole thing going. Checkout our site for write-ups and more info on the team: hack.more.systems
If you are from the Graz area, feel free to drop by our IRC channel or one of the very irregular meetups.
There is gonna be a introductory talk to CTFs and useful tools at the Grazer Linuxtage 2016.
