DL! - E.C.H.O.

Welcome

Welcome to DL!-E.C.H.O. a guide documenting the basics of playing Capture the Flags.

This site is a fork of the original CTF101 project, which is written and maintained by the OSIRIS Lab at New York University in collaboration with CTFd.

We are building on that excellent foundation by adding extra information, and more resources to help you succeed in Capture the Flag competitions.

Ready? What is a CTF?
