Ransomware Attack Paralyzes Major European Airports, Exposing Aviation Cybersecurity Gaps

A sweeping ransomware attack has crippled check-in systems at major airports across Europe, causing severe travel delays and raising urgent questions about aviation cybersecurity. The attack, which began on Friday, September 19, 2025, targeted Collins Aerospace—a major provider of airport check-in technology—resulting in cascading disruptions at hubs like London Heathrow, Berlin Brandenburg, Brussels, and Dublin.

Widespread Disruption Across Europe

According to TechCrunch, delays have persisted for four days, with Heathrow reporting 90% of flights delayed (average delay: 29 minutes), Brussels at 88% (43 minutes), Berlin Brandenburg at 94% (one hour), and Dublin at 91% (26 minutes). Airlines have been forced to revert to manual check-in and boarding procedures, creating long queues and widespread frustration among travelers. Dublin Airport’s spokesperson stated there is currently ‘no timeline at the current time for a fix to be implemented,’ as IT teams continue to work on restoring systems.

Key Facts at a Glance:

Arrest and Investigation

British police have arrested a 19-year-old UK national believed to be a core member of the hacker group responsible for the attack. Authorities are investigating the group’s links and capabilities, while cybersecurity experts warn that this incident highlights the vulnerabilities in the aviation sector’s digital infrastructure.

Critical Infrastructure Under Threat

The World Economic Forum emphasized that this event serves as a wake-up call for the entire industry. With airports relying heavily on complex, interconnected digital systems, a single point of failure can lead to continent-wide chaos. Experts note that while prevention remains critical, building greater cyber resilience—ensuring that essential services can continue even during an attack—is now equally vital.

Public Reaction and Calls for Reform

Social media has been flooded with passenger complaints about lengthy delays, missed connections, and uncertainty. Anxiety among airport staff and travelers is running high, with many calling for urgent investment in stronger cybersecurity measures to protect critical infrastructure from future threats. Regional news outlets report heightened concern about the sector’s preparedness for increasingly sophisticated cyberattacks.

What’s Next for Aviation Cybersecurity?

While travel is gradually returning to normal, this incident has exposed the fragile underpinnings of Europe’s aviation IT systems. The push for collaborative, industry-wide cyber resilience is gaining momentum, as outlined in the World Economic Forum’s Cyber Resilience Compass report. The consensus: prevention alone is no longer enough—robust contingency planning and rapid recovery protocols must become standard.
