This year’s CTF is jointly organized by the HITB NL CTF Crew and XCTF League from China. This is a jeopardy-style CTF with multiple categories of challenges, including: reverse engineering, pwnable, web penetration, crypto, MISC (forensic, network analysis), etc.
The game is hosted on-site and online utilizing the XCTF-OJ Platform developed by CyberPeace Technology, China. Game challenges are jointly authored by Blue-lotus CTF Team (core of Tea Deliverers, b1o0p CTF Team) and HITB NL Team from The Netherlands.
For the on-site game, we have a capacity for a maximum of 25 x 3-man teams. You must be competing on-site if you want to be eligible for the prizes. The game will run for 30 hours over the 2 days of the conference (24th & 25th August starting at 10:00SGT and ending at 18:00SGT on Day 1 and restarting on Day 2 at 10:00SGT and ends at 16:00SGT). The onsite contest will be hosted in the FREE TO ACCESS CommSec area of the conference. You do not need to be a paid conference delegate in order to compete.
The more challenges you beat, the more points you get. Points for each challenge will be dynamically calculated according to the number of teams who manage to solve it. Higher difficulty challenges with less teams that have solved it will carry more points, so teams should choose a strategy that optimizes for high returns. At the end of the competition, the team with highest total points will be named the winner. In the case of two different teams having the same points, whichever team was quickest to reach this high score will be declared the champion. As such, teams are advised to submit flags as soon as they obtain them.
*The 1st Place Team among all of playing teams will be invited to XCTF League Finals to be held in China in September 2017.
We try hard to keep the competition as free and exciting as possible; however we do require teams to adhere to a few simple rules:
