CrySyS SecChallenge 2020: no, thank u, next

Welcome!

We’ve prepared 10 bad/boring/guessing/pointless challenges for educational purposes…

Please, if you will ever organize any CTF events, do not create challenges like these!

Don’t even try to solve them now, it’s a waste of time!

The solutions of the small challenges will be visible on the page from the 25th of February, so you will get a free flag!
