We try to archive our CTFs as well as possible.
For all our past CTFs we offer you virtual machines which allow you to play the CTFs whenever you want!
See this post for more information.
Additionally, we offer static mirrors of the scoreboards with all challenge descriptions and downloads available.
If you have any issues you can always contact us.
Please note that we changed the name from "TUM CTF" to "hxp CTF" in 2017.
