This year’s edition of Säkerhets SM, Sweden’s national Capture The Flag (CTF) competition for high school students, has successfully concluded after an intense season of problem solving and teamwork. 23 teams from Sweden, the Nordic and Baltic countries and Ukraine came to Stockholm.

Säkerhets‑SM is an annual event that highlights the strong and growing interest in cybersecurity among young people across the country. Participants get the opportunity to get to know other young hackers from the rest of Europe, hear inspirational talks from professional hackers, and compete in a broad variety of categories, including web, binary exploitation, hardware and radio. The competition is designed to be accessible to both beginners and experienced players.

This year’s qualifying round was held online at the end of January. During a 48‑hour period, participants worked around the clock to uncover and submit digital “flags” (in the format SSM{…}), proving they had cracked each challenge. Last weekend, on March 12–15, the in-person final was held in Stockholm. 23 teams from all of Sweden, the Nordic and Baltic countries and Ukraine competed.  

There was a tight battle during the entire competition, and the scoreboard shifted the entire time. The winning team was the Ukrainian team Duca.

They didn´t place in the top teams during the qualifying rounds because of a power outage. But they were unstoppable during the finale!

Sofia continues:

It was an extremely fun weekend. This is the first time that we have invited the Nordic/Baltics and Ukraine, and it has been a huge success! We have big hopes of welcoming teams from these countries in the coming years as well. It is important that Europe gets a collected and strong cyber defence, and the competitors of Säkerhets-SM will be the people providing the essential cyber abilities for the Swedish and European total defence in the future.
