Collins Aerospace, a subsidiary of RTX, is working to restore its onsite passenger processing software after a significant cyber intrusion on September 19 disrupted operations at multiple European airports. The attack primarily affected the MUSE system, leading to offline check-in, baggage processing, and boarding operations, causing widespread travel delays and cancellations. British authorities have arrested a suspect in connection with the incident, which is part of a troubling trend of cyberattacks affecting critical infrastructure in Europe. This incident underscores the vulnerabilities in aviation technology and highlights the need for enhanced cybersecurity measures within the industry to prevent future disruptions and ensure passenger safety and operational continuity.
