One of the challenges for #KalmarCTF this year includes some open source tooling we ran into on @_JohnHammond's GitHub. We still have many unsolved challenges left, and there's more than 24 hours left before the end of the CTF - so come play with us by going to kalmarc.tf, and try to make your presence on the scoreboard known!

🎯 Triple CTF Weekend in Copenhagen! 🇩🇰💥 This weekend, @kalmarunionenDM gathered physically for another meetup at Eupry in Copenhagen for an intense and fun-filled hacking meetup - joined by several of our teammates chiming in remotely! 🧠⚡ 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 (@WhiteHatsPWr) 🔹 Dam CTF (@OSUSEC) 🔹 San Diego CTF (@acmucsd) The result? 🥇 We full cleared and won Break the Syntax CTF, Dam CTF, and San Diego CTF - 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. 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. 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 💪🧠✨ ✨ Special shoutou to our sponsors whose support makes these meetups and our CTF journey possible: Industriens Fond, JN Data, @Dubex, ICSRange If you’d like to support Kalmarunionen, reach out to Rolf Lunn or Morten Eskildsen on LinkedIn or write to us at sponsor@kalmarunionen.dk. #kalmarunionen #ctf #hacking #cybersecurity #community #breakthesyntax #dam #sdctf

@kalmarunionenDM is the #1 CTF team in the world. We climbed from 66th in 2020 on @CTFtime to 1st in 2024, thanks to late nights, fierce competitions, and an incredible team spirit. We never stopped trying harder while having fun. On to more triumphs in 2025! #CTF #Hacking

@jens_myrup Det er fandme flot. Stort tillykke til hele holdet og holdet bag!!! 🎉🇩🇰💪♥️

Vi er godt tilfredse. Vi ligger i den absolutte top sammen med store lande som Tyskland, Italien og Polen. Og vi har vist at vi konsistent ligger med i toppen. Det ændrer ikke på ambitionen om at tage pokalen med hjem til næste år.

4th position: Denmark 🇩🇰! #ECSC2024

Danmark får 4. pladsen. Det er 4. år i træk Danmark ligger i top 5. Det er så stærkt gået!

@TeamAustriaECSC @h4ckd0tm3 @ECSC_openECSC @ecsc2024 Nothing short of AMAZING. 💪💪💪

Next on stage at #ECSC2024, our popax21 aka Matthias Pleschinger who won ALL 4 rounds of @ECSC_openECSC ! We're so proud of you! @ecsc2024

Der bedes til Cyberguderne inden afgørelse af #ECSC2024 i aften

@jens_myrup Andet end: De er fa’me seje! 💪💪💪🇩🇰🇩🇰🇩🇰

Alt for tidligt at sige noget som helst

@jens_myrup Sådan. Godt kæmpet!!!

Lidt trætte efter en lang dag. Humøret er stadig højt - vi kender ikke stillingen, men vurderingen er at vi med lidt medvind kan være med i top 5. Det er super stærkt!

@kalmarunionenDM @GoogleVRP Huge congratulations on a fantastic team effort. 💪🇩🇰🥇🍾🏋🏻🥕

We are thrilled to announce that we have emerged victorious in Google CTF, securing the top spot for on CTFtime.org Global CTF Ranking and earning $12,345 in price money from @GoogleVRP. What a weekend 🚀🚀🚀 Thanks for a great competition!

Så er det i morgen 4. maj finalen af De Danske Cybermesterskaber afvikles på @aalborg_uni i Kbh. De 100 bedste unge hackere dyster om placeringer - og om at komme i betragtning til Cyberlandsholdet. Håber at både #dkmedier og #dkpol følger med! @Industriensfond, @Cybersikkerhed

I’m not going to be answering many questions here, about Apple TV’s adaptation of Neuromancer. I’ll have to be answering too many elsewhere, and doing my part on the production. So I thought I’d try to describe that, my part.
