The BSides CTF Walkthrough Session is a live, introductory tour of some of the selected challenges of this yearly BSides Luxembourg Capture-the-Flag competition. During this interactive activity, we will not walk through every challenge step by step, instead we will very specifically discuss the tasks that the participants found most interesting and frustrating, this could be a web exploit, LPE, OSINT or crypto puzzle, so that by the end of the session both those with little experience and those with more experience have a more overall idea of how to think during a CTF.
