About

University of Porto - CTF Team

xSTF (Extreme Security Task Force) was created as a CTF team in 2015 at Departamento de Ciência de Computadores da Faculdade de Ciências da Universidade do Porto (DCC-FCUP). Most members are computer science, informatics, and infosec students from the University of Porto, and we also count on the help of some professors.

We play CTFs regularly and we've hit the top 100 on ctftime.org several times. Our dream goal is to reach the top 10! 😊
