Several European airports faced long delays and flight cancellations on Friday (Sep 19) after a cyberattack hit a service provider that runs check-in and boarding systems of several airports. Major airports like London Heathrow, Brussels, and Berlin reported problems, and passengers were issued an advisory to check their flight status before travelling. According to the EU’s cybersecurity agency ENISA, the issue was caused by a ransomware attack on a service provider, Collins Aerospace. ENISA said in a statement that they are aware of the ongoing disruptions but cannot share more details for now.
