Posted in RUNESEC CTF 2017 Written by Marios Nicolaides (styx00)

The RUNESEC CTF 2017 is now over and we would like to thank everyone who participated. We had 91 participants in total, out of which 40 were ECSC Eligible and 51 ECSC Ineligible. We hope you’ve enjoyed the CTF and you learned a thing or two.

Please note that the CTF will remain online in case someone wants to try and solve the challenges for fun/training.

We would like to congratulate the winners and let them know that we will be contacting them directly over the next few days to arrange delivery of the prizes.

In regards to the ECSC competition, we will process the results and we will endorse the participants who did well to the appropriate parties to be considered for inclusion in the Cyprus team. However, we state clearly that we cannot guarantee that you will get a spot on the team, as the decision is not up to us (even if you came 1st).
