After the cyber attack on the aviation system, chaos in European air travel continues

A key airline's check-in system suffered a cyber attack, forcing staff to manually process passenger check-ins. Airports in Berlin, London, and Brussels continued to face delays on Sunday. The system disruption originated from a cybersecurity incident at Collins Aerospace on Friday evening, which caused its MUSE software to crash. This software platform provides technical support for the check-in, boarding, and baggage handling systems of many airlines worldwide. Due to the inoperability of self-service check-in kiosks and baggage drop machines, airports had to rely on manual processing, slowing down passenger flow. Berlin Brandenburg Airport reported that delays were still ongoing; Heathrow Airport stated that "the vast majority of flights" were still operating normally but advised travelers to check flight status before heading to the airport, and indicated that long-haul passengers do not need to arrive more than 3 hours in advance, while short-haul passengers do not need to arrive more than 2 hours in advance. There has been a significant increase in cyber threats targeting infrastructure and the aviation sector this year. A report released in June by French defense company Thales showed that ransomware attacks in the aviation sector increased by 600% year-on-year, with dozens of incidents affecting airlines, airports, navigation systems, and related services
