In the early hours of September 20, 2025, chaos erupted across some of Europe’s busiest airports as a sophisticated ransomware attack crippled automated check-in and boarding systems. The attack targeted Collins Aerospace, a subsidiary of RTX Corp., whose MUSE software platform handles critical operations for numerous airlines and airports. The European Union Agency for Cybersecurity (ENISA) confirmed the incident as a ransomware attack, emphasizing the vulnerabilities in third-party software providers that underpin global aviation infrastructure. DW reported ENISA’s identification of the specific ransomware variant, which caused severe chaos over the weekend at major flight hubs. The incident aligns with a pattern of high-stakes ransomware operations, as seen in a CBC News analysis highlighting vulnerabilities in sectors like transportation.
