Crisis in Icebergen: How NATO crafts stories to sharpen cyber skills

NATO’s Cyber Coalition exercise in Tallinn brought together around 1,500 practitioners from 29 member and seven partner nations to rehearse coordinated cyber defense across seven concurrent, realistic storylines—such as attacks on critical national infrastructure, adversaries lurking in backups, a satellite communications compromise inspired by Russia’s 2022 Viasat attack, and a fuel management malware incident. The piece explains how scenarios are crafted and tuned through multi-stage conferences to mirror current tradecraft while avoiding Article 5 triggers, and emphasizes the exercise’s collaborative, non-graded design that prioritizes cross-domain effects, information sharing, and pacing over competition.
