🔜 What's next
- Google Hackceler8 Finals, Mexico - we're among the top 8 and can't wait to live-hack on stage.
- Copenhagen meetup - another big team session to keep the momentum rolling.

What makes this season special: our seasoned members are still all-in, and our younger talent is levelling up every single event. That blend of experience and growth is exactly what we hoped for when we started Kalmarunionen - upskilling ourselves while building a pipeline for others.

This is our fourth ASIS win, and it's a reminder that the top is never guaranteed. The field keeps getting sharper, and staying there takes a lot of grit.

It's been a minute since our last update. We played the @defcon.bsky.social CTF Finals in Las Vegas, with teammates on-site and a Danish venue.

Denmark’s Minister for Digitalisation, @carolinestage.bsky.social, stopped by mid-CTF to support us and talk cyber talent and the future of security. We hope you liked the hoodie! 😄

It’s been a wild first half of the season, and Kalmarunionen currently sits at #1 on the global CTF leaderboard!

✨ Special shoutout 🙌 to our sponsors whose support makes these meetups and our CTF journey possible:
Industriens Fond, JN Data, Dubex, ICSRange

With the bigger CTFs postponed, we got an opportunity to slow down and dive deeper - sharing knowledge, solving problems together, and enjoying capturing flags. We play to win, but we also play because we love the challenge 💪🧠✨

Weekends like this are part of what makes Kalmarunionen special: a mix of collaboration, curiosity, and fighting spirit - and a chance for aspiring members to challenge themselves alongside some of the best CTF players in the world.

The result?
🥇 We full cleared and won all three CTF's - a triple win that kept the flag bell ringing non-stop all weekend!

A big thanks to Eupry for hosting us - we had a blast solving challenges together, sharing knowledge, and pushing each other to think deeper and faster.

While we were initially prepping for two bigger CTFs that unfortunately got postponed, we quickly adapted and dove headfirst into three other competitions instead:
🔹 Break the Syntax CTF
🔹 Dam CTF
🔹 San Diego CTF
