What does it take to build a complex cyber operations exercise? Months of planning, coordination and testing. This week, the #CrossedSwords2026 team came together for the Main Planning Conference, bringing different exercise elements around the same table to refine the scenario, coordinate activities and work through the details ahead of the exercise. A big thank you to all planners who joined us!

The conversations sparked at #CyCon2026 are still moving forward. We are delighted to see them continue through a new Articles of War series exploring new technologies, military AI and international humanitarian law. 🔗First in the series: lieber.westpoint.edu/cycon-2…

Following their earlier @CCDCOE publication "Ontological Foundations of Cognitive Warfare" a Ukrainian research team now turns to the human agent. 🎯The new paper "A Structural Model of the Human Agent in Cognitive Warfare" asks a question most defences skip: when the mind of a commander, analyst, or official is the target, what exactly is being hit? Not what they believe, but how they decide. 👉Read the full paper: ccdcoe.org/library/publicati…

During a recent working visit to Kyiv, @SSSCIP and @ccdcoe outlined areas for strategic partnership and discussed the implementation of joint initiatives aimed at strengthening collective cyber resilience. 🤝 👉Read more: ccdcoe.org/news/2026/nato-cc…

Last week, @ccdcoe hosted the Advanced Exploitation Course (EXA) in Tallinn. Over an intensive week, the students recapped some basics and then learned through practical challenges how to run exploits in modern operating systems and bypass today’s security mitigations step by step. The course is highly technical and involves a lot of hands-on command-line work. We hope the 19 students from 10 different nations enjoyed the course and left with sharper exploiting skills!

#LockedShields2026, the world’s largest live-fire cyber defence exercise, brought together 4,000 participants from 41 nations to strengthen their ability to protect critical infrastructure and military systems against real-time cyber threats. Thank you to everyone who contributed to its success – see you at #LockedShields2027! 🛡️
