We are the BTU Cyber Security and Capture-The-Flag Club - or just BTU CyberSec Club / BTU CTF Club in short. We are a group of BTU students and interested people looking to expand their knowledge in all kinds of cyber security related topics. While studies at the BTU already do a great job at giving you theoretical and practical foundations, we found that there is a lot more you can do in cyber security than can be taught in the lectures: Be it designing our own secure systems and figuring out how to break into them, hacking our way through our computer science building or simply participating in CTFs as a team. Thus, we founded this club in May of 2023 so that we can teach each other new skills, experiment with new attacks and keep up with cyber security news together. Sometimes, we even manage to organize professional talks to gain an in-depth view into the state of the art.

While hacking usually requires some coding skills, really everybody is welcome to join us in the club. After all, Cyber Security is not just about hacking networks or reverse engineering computer programs... you may also need electrical engineering to attack the hardware that a system is running on, or you may have to dive deep into mathematics to crack a cryptographic algorithm. And even past the bounds of computers, one could breach security or deanonymize a target simply by combining openly accessible information (OSINT) or using techniques of traditional forensics. If you are interested in the club, we invite you to stop by one of our meetings or join into our Discord, both of which you will find below!

Our club is still fairly new.. and so, we are still working on some of the foundations. Maybe you would like to help and add your own mark to the club? Some of our current projects are:

• Building up our infrastructure: Extending our Discord bot, setting up a server for CTF tournaments, creating and hosting a more polished and integrated website, building our knowledgebase for CTFs, ...
• Creating a biometric system to secure and pen-test against attacks
• Using software-radios to try out attacks against digital door locks

Are there projects you would like to participate in or do you have a cool project idea yourself? In either case, we are happy to hear your thoughts through Discord or in the meetings!

Outside of meetings, our club communicates and organizes itself mainly through Discord. If you want to participate or just want to have a look at what we do, you are very welcome to join us here: https://discord.com/invite/hsXCmJmu6x
Still, if you prefer, you can also simply reach us via email at cybersecurity-club(at)b-tu.de.

We currently have no regular meeting dates. Upcoming meetings will be announced as required and can then be found on our Discord server. So if you would like to get in touch with us and there happens to be a meeting coming up, this would certainly be a good opportunity to get to know us directly!
