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.
Instead of a lecture where the speaker tells the audience all the answers, the session is constructed in a form of a conversation with the players of the CTF. We will begin with a brief summary of the BSides Luxembourg 2026 CTF: types, difficulty tiers, and some statistics (solves, first bloods, most/least solved challenges). Following that, it will be audience-driven: we will request the participants to tell which issues they would like to rediscover and then untie them, on the spot.
For each chosen challenge, we will:
- Explain the core idea and what clue in the statement pointed to it.
- Show the critical steps of the solution, highlighting typical mistakes and dead ends.
- Discuss alternative approaches, tooling, and how similar bugs appear in real‑world systems.
This formatting allows the session to be useful regardless of whether you were able to solve many flags or couldn't get through: you can take your questions, learn how other people tackled the same problem, and learn useful tips on how to solve CTF problems practically, which you can apply to future CTF events.
