The Midnight Sun Conference 2023

MidnightSun is Sweden’s biggest CTF event involving teams from all over the world. It has grown to include an offensive and policy focused conference by hackers, for hackers in Stockholm, Sweden.

This year, Hacking For Soju and Cparta pulled together a lineup that represents some of the most unique exploitation, reversing, and offensive-oriented researchers out there. Come attend some lectures, observe the CTF premiere league, compete in 1v1 pwn, and hack under the Midnight Sun.
