DEF CON CTF 2017 Final Scores and Data Dumps

We'd like to again congratulate every team that played our final finals at DEF CON 25 this past weekend. We're very happy every team was able to score and patch services on our brand new cLEMENCy architecture. It was a lot to ask of our competitors, and we couldn't be more thrilled with their collective performance this weekend.
