Capture the Flag - Cybersecurity

[Kathleen Baert]

Hello - does anyone have suggestions for Capture the Flag style competitions for high schoolers? We've spent this semester going through cyber.org's Intro to Linux and Cybersecurity 701. Great group of motivated students, pretty willing to explore and try things, most don't need a lot of handholding if they're interested, so I'm looking for very open-ended ones. I've gone through the Cyber.org's CtF options, but don't like them very much because they're don't seem to allow for a lot of exploration, and don't give them any form of virtual environment, and instead just force one (typically googleable!) answer. 

Unfortunately anything I do in my class must be Chromebook friendly, and preferably free if possible! 

Thanks!

You could try Hack the Box at hackthebox.com. They have a few labs and CTFs, but they also allow you to create your own. I'm not sure how well it will run on a chromebook, but it is web based so I'm guessing it would work ok.
