During SHA 2017 we will be organizing a CTF that can be played both onsite and online. This blog post is meant to provide some insight into the SHA 2017 CTF that is currently being built.
What is a CTF
A CTF is a Capture The Flag hacking game. The game generally exists of multiple hacking-related challenges which need to be solved during the time the CTF takes place. Players play in teams and compete against each other. Most CTFs run for about 24-48 hours and can be played online. During the CTF all challenges are provided in a controlled environment, and everything is completely legal. No hacking of external parties or the other teams takes place.
Most of the hacking events or conferences these days have an official CTF during the event/conference. A good example is the yearly CTF at CCC. We personally think a CTF is a great addition to an event and provides visitors another form of technical entertainment.
To warm everyone up for the CTF, we will be hosting a teaser round. During this teaser round it is possible to win tickets for SHA2017! The SHA organization has provided 4 tickets for the team that solves (without cheating...) all of the challenges first. Failing that, the team that has the most points at the end of the teaser round gets the tickets.
Dates and times
Basically, we have 6 categories with each challenges in multiple difficulties.
Besides the main CTF we will be hosting a "junior" CTF which contains challenges for beginning CTF players, to make sure everyone gets the chance to enjoy the CTF.
The CTF is created by an experienced group of hackers who are part of the Eindbazen CTF team. To get a better understanding of the setup and kind of challenges that players will encounter we would like to refer to the CTF that was organized by the same team during OHM 2013, which was called ebCTF: https://ebctf.nl/
We hope to create an amazing CTF for SHA2017 and we hope this blog post gave a good insight in our upcoming plans. For more information about the CTF and the upcoming Teaser round, follow us on Twitter: @sha2017ctf or keep an eye out on http://ctf.sha2017.org
