TG:Hack is an onsite jeopardy style CTF hosted every year at Norway's largest LAN party The Gathering, which takes place at the Viking ship in Hamar. We focus on making guiding tasks for beginners, and challenging tasks for a little more experienced CTFers.
We have a pre-contest for beginners, starting 15th of February. The main competition starts 17th of April, 18.00 (CET), and ends 20th of April 18.00.
After the main competition has ended, we open all tasks publicly for learning purposes. The site will be up until new years eve, and then we count down for the next CTF.
Writeups are published at https://github.com/tghack after each competition.
