A new cyberattacco has put in crisis European air traffic, causing serious inconvenience to the Airports of Brussels, Berlin and London-Heathrow. The attack involved the Collins Aerospace Muse software, a fundamental platform for the management of check-in and the delivery of the luggage of numerous airlines. Due to the interruption, the operations have been managed manually, with inevitable delays and cancellations of flights.
So far the canceled flights have been over 29, while about a hundred has undergone significant delays. Brussels airport confirmed that hackers came into action during the night between Friday and Saturday, suggesting to passengers to check the status of their flights before arriving at the airport and check-in online in advance.

The computer attack had a devastating impact on air traffic, destabilizing operations that are normally highly automated. Unfortunately this is only the last of a series of IT attacks that are aiming at the critical sectors of infrastructure, highlighting the vulnerability of systems that manage vital daily operations such as air transport.
