What is CTFtime?

There are a lot of Capture The Flag (CTF) competitions in our days, some of them have excelent tasks, but in most cases they’re forgotten just after the CTF finished. We decided to make some kind of CTF archive and of course, it’ll be too boring to have just an archive, so we made a place, where you can get some another CTF-related info – current overall Capture The Flag team rating, per-team statistics etc.

CTF organizers, we need your cooperation!

All the others – send your BTC to support the project 12KYUVrM1HGYczPW3oUEz2NEjdUHqFtjfm.
