In the last 24 hours, the EU Agency for Cyber-Security (ENISA) conducted an EU-wide cybersecurity exercise, called Cyber Europe 2026, which involved 5,000 experts, called to test Europe’s response to attacks on critical transport infrastructure. The exercise simulated a cyberattack on European rail and maritime networks with severe operational disruptions that escalated into a full-blow cybersecurity crisis. Involved in the exercise were cybersecurity experts from the public and private sectors, policymakers, European institutions, industry and partner countries (United Kingdom, Norway, Switzerland and Ukraine). The exercise was also the very first Europe-wide test of the 2025 EU Cyber Blueprint, which clarifies roles and responsibilities in a crisis. If cyberattacks hit ports or railways, “effects can reach far beyond transport, disrupting trade, military mobility and crisis response”, the Executive Vice-President Henna Virkkunen explained. As hybrid threats blur the line between civilian and military infrastructure, preparedness is not optional, because “cyber threats cross borders in seconds. Europe must be able to act just as fast, together with its closest partners”.
