As a long-time partner of the Nuit du Hack event, Sysdream has been hosting the Capture The Flag challenge for years. This time, we will welcome the top 10 teams, that passed the online qualification of last April, for a night of competition. The challenge will follow the attack- defense format: every team has an identical network and uses its skills to find, exploit and patch vulnerabilities under constant enemy fire. On site, the public dashboard will display most of the information. You can follow also us on Tweeter for a live tweet session, using #ndhctf.
