A cyberattack caused disruptions at several major European airports on Saturday, raising concerns about the security of vital systems.
The attack, which targeted check-in and boarding systems, led to delays as airports were forced to rely on manual processes. Airports in Brussels, Berlin, and London were affected, though many others reported no impact.
Brussels Airport stated the attack hit the service provider for check-in and boarding, causing significant issues.
While the immediate impact on travelers seemed limited, experts warn that the incident exposes weaknesses in the digital infrastructure that supports air travel. The source of the attack remains unknown, but possibilities include hackers, criminal groups, or even state-sponsored actors.
Travel analyst Paul Charles expressed concern, noting that the attack targeted a major aviation and defense company. He described it as a sophisticated attack affecting multiple airlines and airports through a core system.
Airports are advising travelers to check their flight status for potential delays and apologized for any inconvenience caused. Some passengers reported frustration with long lines and limited staff at check-in counters.
Collins Aerospace, the company whose software was affected, confirmed a “cyber-related disruption” to its MUSE system and said they are working to restore service.
Cybersecurity experts highlighted the vulnerability of the airline industry due to its dependence on shared digital platforms. Charlotte Wilson from Check Point noted that cybercriminals are increasingly targeting the aviation sector, often exploiting third-party platforms to cause widespread disruption.
The investigation into the attack is ongoing, with experts examining potential motives.
