Flight delays continue plaguing major European airports including London Heathrow, Brussels, Dublin, and Berlin following Friday's ransomware attack on Collins Aerospace. The cyber-attack targeted the company's Muse software used for check-in and boarding systems across multiple airlines worldwide.

Collins Aerospace, a subsidiary of RTX, says it's in final stages of restoring full functionality while working with four affected airports. Airport staff have resorted to manual processing as kiosks and bag-drop machines remain offline. Brussels canceled 63 flights on Monday alone.

The EU's cybersecurity agency confirmed it was ransomware, where hackers lock systems demanding payment. Officials suggest state-sponsored actors could be responsible, though private entities remain possible culprits. Airline stocks dropped Monday, with IAG falling 1.2% and easyJet down 1.4%.
