Last November we hosted the CTF 2019 “The 5th Element – It mu5t be found“. CTF? A capture the flag is an IT security competition with various challenges. We held a Jeopardy, which, similar to the TV show, provided various tasks in different categories, such as reverse, crypto, web and misc. You can find a suitable blog post on CONCORDIA.
After the last CTF, where I tried myself: building and playing are two pairs of boots and no matter how stupid you do, you always learn something. Follow-up writeups are practical.
