During the weekend of 6-8th of July, our CTF team Dragon Sector played in an invite-only competition called WCTF, held in Beijing. The other participants were top-tier groups from around the world (e.g. Shellphish, ESPR, LCBC or Tokyo Westerns), and the prize pool of the contest was a stunning $100,000 USD. Each of the 10 teams was obligated to provide two tasks, at least one of which had to run on Windows.”]
