CHALLENGES(2020) CHALLENGES(2020)

Note

Some challenges were hosted on our infrastructure. They are now available as Docker images which you can download and run on your own computer. If you want to solve the challenges in the same way as the participants of the CTF, you should treat these Docker instances as blackboxes and avoid peeking in them.

All zipped challenges should include some solution or explanation.
