What's a CTF?
In computer security, Capture the Flag (CTF) is a computer security competition. CTF contests are usually designed to serve as an educational exercise to give participants experience in securing a machine, as well as conducting and reacting to the sort of attacks found in the real world. - Wikipedia
This CTF is a part of CodeDay's new city-vs-city seasonal competition: CodeCup! More info on that here.
