I like the idea, and wanted to tackle one of these.

liberty: seems like it's going to be a problem since it receives data from a server over the network, but since the CTF is over, that's no longer possible?
FlareOn Six (2014), I'm not able to find the binary for this challenge. I have looked at several write-ups, and the ones that do have links to the binary are dead. :(.

Awesome. I also contacted gaasedelen and he still had a copy of the binary, so I have a copy to work on C6.zip. Solve: https://github.com/Caesurus/usercorn_examples/blob/master/2014_flareon_six/readme.md
