Michal is a web developer, speaker & engineer. Building report-uri.com, making the web a bit more secure place. Full disclosure: we'll talk about report-uri.com too but this won't be a marketing talk, don't worry. I was talking about it before I started working on it, and talking about it is one of the reasons why I was invited to join. Here's an article about me joining report-uri.com.

20:30 Uhr (08:30pm) - What the flag is CTF? (Main talk)

(in German or English)

Since 2011 Mallle's CTF-Team Eat, Sleep, Pwn, Repeat organizes a Capture the Flag contest for people at Chaos Communication Congress and from all over the world, where over a thousand teams are competing every year who's getting the most points from captured flags.

In this talk, he will give you a short overview about what a CTF is, the challenges, the players, the community and how much fun it is to play. After a short introduction of the different topics from reverse engineering, binary exploitation, over crypto(graphy) to web(-security) tasks he will show some of the web-challenges from this year's junior contest and solve them in a live-hacking session.

So you can get an idea what you are up to when you decide to play, getting a closer look into web issues and see how to solve our challenges even if you never played a CTF before.
