We try to archive our CTFs as good as possible. For all our past CTFs we offer a static mirror of the scoreboard with all challenge descriptions and downloads available.
For the hxp CTF 2017 we also put all challenge services into one virtual machine which allows you to play the CTF whenever you want!
See this post for more information.
Please note that we changed the name from "TUM CTF" to "hxp CTF" in 2017.
If you have any issues you can always contact us.
