Information security is LosFuzzys’ specialist area and passion. Their team participates successfully in IT Security competitions and disseminates knowledge via self-developed challenges and in courses at TU Graz.

Under the motto Don’t feed the bugs, LosFuzzys track down security vulnerabilities in IT systems. Their aim is to build competences in the area of IT security and to gain new knowledge to make IT systems more secure in the future. LosFuzzys prove their skills at world-wide Capture The Flag competitions. In Jeopardy competitions, participant teams tackle tasks in the area of IT Security that are often inspired by real situations and problems. In attack-defence competitions, teams have to find out and exploit vulnerabilities in other teams’ systems and simultaneously eliminate their own vulnerabilities in order to defend their own system. Training and exchange takes place in the team’s FuzzyLab on Campus Inffeldgasse. In addition, LosFuzzys develop their own IT security challenges which can be used by all other interested persons for training purposes as well as in courses at TU Graz. Besides providing a seminar for TU Graz students, LosFuzzys also communicate their knowledge to businesses and co-operation partners in the form of lectures.
