This long delayed article is a write-up of the Swiss Cyber Storm Social Challenge which took place on May 14, 2011. Because of lack of time I simply did not finish this article earlier, however since I really enjoyed the challenge I decided to release it anyways, even though it is a bit dated now.
During the recent Defcon 19 CTF pre-qualifications, one of the challenges included to connect ‘quicker’ to a web server. While figuring out what the solution was for this challenge one of the things I tried was to send the HTTP GET request already in the TCP handshake stage. Sadly enough this had nothing to do with the real solution of this case, the real solution was making use of SPDY to connect to the server, this is also explained by one of the other teams in a write up here. However it was a nice exercise to create packets with scapy again and since I could not find a lot of information on the topic I decided to create this short write up on the topic.

I only joined the CarGame in level 4 (my write-up for level 4 can be found here), which meant I could not qualify any more to play the CarGame challenge during the conference. However since the challenges seemed fun I did the last two CarGame challenges anyway. The number and title of this challenge were:
I submitted my solution and it was accepted by the organisation, however I do not know if this was the solution the organisation expected and if any other participants have other solutions.

I recently have been to the Swiss Cyber Storm 2011 conference which is an ‘International IT security conference’ held in Rapperswil, Switzerland. The conference took place from 12 till 15 May 2011 and the conference consisted of both Briefings and Wargames. The Cyber Storm Briefings were on Thursday and Friday (12-13 May 2011). There were three tracks and a lot of interesting presentations. The Swiss Cyber Storm Wargames were on Saturday and Sunday (14-15 May 2011) and there were 3 leagues to play in. The challenges were very challenging and the split in three different levels of difficulty made it fun for everyone. The conference in total was very well organized (Swiss precision?).
