About the Event

A Cyber Security Contest for German Students

In Germany, just like in the rest of the world, cyber security has become a strategic priority for organizations across all sectors. In this context, training and hiring young potential in the area of information security has become even more crucial than in the past.

In 2015, cyber security specialists initiated the first Cyber Security Challenge Belgium. They believed in raising awareness and interest of students that are about to complete their education through a country-wide challenge.

After 4 successful editions and each year growing keen interest from the industry, the event has become a not to miss event for students and industry professionals and now launches a new initiative in Germany together with Bonn University and in collaboration with SANS Institute – the Cyber Security Rumble.


March 13th - 14th, 2019
Registered teams in Belgium and Germany are invited to solve challenges on an online platform, over a duration of two days. The 12 top German teams are invited to the finals that will take place in the lectures hall in the middle of the Poppelsdorf campus of the Bonn University.


March 29th - 30th, 2019
Qualified teams must solve new, more complex challenges during 2 days. Train tickets to Bonn and back to their home town will be organized for the top 12 German teams. Hotel accomodation and meals are also offered to the participating teams during the 2 days of the final round..

The Audience

Audience targeted consists of students from German academic institutions, studying either for a bachelor or a master degree with a focus on information technology. Detailed knowledge of IT Security is not required to join


The top German teams and Belgian teams will also compete during the finals on a shared leaderboard. Which country will score best?

Based on the principles of a Capture The Flag (CTF), this computer security competition is a challenge-based game played by teams of maximum 4 students. Over a limited timeframe, the teams must solve challenges covering a wide range of security issues, e.g. cryptography, reverse engineering, network security, web or mobile application security, wireless and forensics analysis. Complexity of challenges range from trivial up to very difficult.

Anyone who is a student in a German academic institution is allowed to compete in the qualifiers. Participants must be 18 years of age; if you or a member of your team has not reached that age, please contact us before registering.

Consult the rules of engagement for more information.

After the qualifiers, the top 12 German teams who are eligible to compete in the finals will be invited.

Of course! Challenges have been designed for students, not for security specialists, so you don’t need to be a security expert to join. A good general IT knowledge and a good level of motivation is what matters most. The Cyber Security Rumble is composed of challenges designed with all levels of complexity.

Yes you can! But working in a team is always more fun, and you'll probably be able to solve more challenges than by yourself. If you have some trouble finding teammates, head over to the CSR 2019 Qualifiers Facebook event page and find other students who are looking for a team to join.

A good way to get started with the Cyber Security Rumble is to take a look at write-ups from some of the past Cyber Security Challenge Belgium editions:

Once you feel you’re ready to try and solve some challenges on your own, you could take a look at the "awesome-ctf repository": it contains a list of useful tools sorted per category (reversing, cryptography, web, …). It also contains a list of "wargames" available 24/7 for practicing.

For example, the "overthewire wargames" feature a series of challenges, and suggests an order in which to play them based on their difficulty. There’s also an IRC chat channel available, so if you’re stuck you can always go ask for some help there.

The first "Qualifiers" round of the event will take place online and will be common for Cyber Security Challenge Belgium and Cyber Security Rumble: registration will provide each team member with an account to login.

The second "Final" round of the event will be hosted on the Poppelsdorf Campus at University Bonn

This challenge is an initiative of NVISO and University Bonn in collaboration with SANS Institute and supported by large private corporations and banks (our sponsors), as well as public agencies and organizations that are committed to raising our country’s awareness on cyber-security threats and help train a generation of security-aware professionals and security experts. All sponsors are regularly recruiting talented graduates to re-inforce their security teams, so you may also be meeting your future employer at our event!

We have a wide range of challenges ranging from general security knowledge over mobile security to reverse engineering and cryptography. Some of them will be easy and others will be a challenge even for the more skilled participants. To get a feel for what you can expect you can always head over to the write-ups of the previous editions on GitHub ( 2015 and 2016). Don't expect a completly identical challenges for this year though!
