Forwarding a message on behalf of the saarsec team. If you liked our MiniCTF, consider attending join them and their workshop!

 

Hello there,

we, the Capture-the-Flag Team saarsec, consisting of students and lecturers from Saarland University, are giving a workshop to familiarize students with Capture-the-Flag competitions as well as attacking and defending against security vulnerabilities. CTFs are a great way to actually fiddle around with the practical details of mounting attacks and defenses that were theoretically discussed during your studies. This practical experience can not only be beneficial for your studies but also come in handy during later stages of your career. The workshop starts with a short introduction to Linux, followed by different topics such as File Inclusions, SQL Injections, and Command Injections. For each topic, we will discuss how we can find these vulnerabilities, exploit them on a large scale, and how we can fix them. Then, for each each topic, you'll spend more than 50% of the time in each slot on actual challenges.

At the end, we will host a CTF for all workshop participants where they can use their newly acquired skills against each other.

 

FAQ:

Q: When and where?
A: April 10th and 11th, entirely virtually

Q: Requirements?
A: We do not require any certain skills as we will start with the basics. However, the knowledge from Cysec1 or Security is definitely an advantage.

Q: Sounds awesome! Where can I register or get more information?
A: https://workshop.saarsec.rocks


See you there,

The miniCTF will take place from Monday 12pm to Friday 6pm. You can access the miniCTF platform here: https://minictf21.scy-phy.net/.
To solve challenges you will first need to create a personal account and then join your team. You can find your teamname and token on your Personal Status page. Once the CTF started, please verify that your challenge contains all information and files to be solvable but does not leak any unintended way of solving it.
Each challenge will yield 2 points that count towards your admission for the exam (except for the challenge your team submitted). You can reach a maximum of 10 points from solving challenges in the MiniCTF. (Solving your own challenge will not yield any points towards admission but yield an infinite amount of shame to your own team).
If any problems occur regarding the miniCTF (challenge not solvable, team not joinable, etc.) please contact your tutor, use the Discord channel or AskBot.
