Cyberattack on Collins Aerospace Disrupts European Airport Operations

A cyber-related incident targeting Collins Aerospace's MUSE check-in and boarding software led to significant disruptions at major European airports over the weekend. Airports in London, Brussels, and Berlin experienced long queues, delays, and flight cancellations as airlines reverted to manual check-in processes.

Collins Aerospace, a subsidiary of RTX, confirmed the issue as a "cyber-related disruption" but did not provide further technical details. The MUSE system, integral to electronic check-in and baggage drop services, was compromised, affecting multiple airlines and airports.

By Sunday morning, Heathrow Airport reported that most flights were operating, though manual workarounds and longer processing times persisted. Brussels Airport advised passengers to arrive early due to ongoing schedule impacts, while Berlin Brandenburg Airport continued to implement contingency procedures.

Authorities in several countries have initiated inquiries into the incident to determine its origin and assess system resilience. The disruption underscores the vulnerabilities associated with centralized passenger-processing platforms and the cascading effects such incidents can have on airport operations.
