ZenHack is a Zena-based CTF & cybersecurity Team founded in 2017 by a group of students and researchers interested in cybersecurity.

The team is located in Genoa (Genova in Italian), Italy, and is hosted by the Department of Informatics, Bioengineering, Robotics and Systems Engineering (DIBRIS) of the University of Genoa.

Our name comes from Zêna, the dialectial name of Genoa, and our logo is inspired by the colors of the ZX Spectrum.
