Dublin Airport experienced significant operational disruption due to a Europe-wide cyber attack targeting check-in and boarding systems. As of midday on Sunday, 13 flights (9 inbound, 4 outbound) were cancelled, while airlines in Terminal 2 resorted to manual processes for bag tags and boarding passes, causing delays in check-in and bag drop. The incident forced passengers to allow extra time for procedures, with advisories to contact airlines directly for updates. While no data breach or ransomware was reported, the attack disrupted critical airport infrastructure, leading to financial losses for airlines, reputational damage for the airport, and passenger inconvenience (e.g., missed connections, stranded travelers). The incident also triggered a secondary security alert in Terminal 2 on Saturday, requiring evacuation and intervention by Gardaí and the Defence Forces’ EOD team, though this was later deemed unrelated to the cyber attack. The prolonged system outage highlights vulnerabilities in aviation cybersecurity, affecting thousands of travelers and airline operations across Europe.
