BERLIN (Reuters) -Airport disruptions that affected automated check-in systems in recent days were caused by a ransomware attack, the EU's cybersecurity agency said on Monday, highlighting the growing risks of such attacks to critical infrastructure and industries.
Several of Europe's biggest airports still faced disruptions on Monday after hackers knocked out automated check-in systems provided by Collins Aerospace, owned by RTX, affecting dozens of flights and thousands of passengers since Friday.
"Law enforcement is involved to investigate" malicious software that locks up data until the victim pays to have access restored, the ENISA agency said in a statement, without saying where the ransomware attack originated from.
Governments and companies have been the targets of cyberattacks in recent months, including luxury carmaker Jaguar Land Rover, which had to pause production as a result.
ATTACKS TEND TO TARGET HIGHER-PROFILE VICTIMS
Rafe Pilling, director of threat intelligence at British cybersecurity firm Sophos, said there have been more ransomware attempts targeting higher-profile victims because of the attention they bring, but such attacks weren't becoming more frequent.
"Disruptive attacks are becoming more visible in Europe, but visibility doesn't necessarily equal frequency," he told Reuters.
"Truly large-scale, disruptive attacks that spill into the physical world remain the exception rather than the rule."
A survey of some 1,000 companies by German industry group Bitkom found that ransomware - malicious software that locks up data until the victim pays to have access restored - was the most common form of cyberattack, with one in seven companies having paid a ransom.
MANY AIRPORTS YET TO RESTORE CHECK-IN SYSTEMS
Collins Aerospace said on Monday that it was working with the affected airports, including Brussels and London Heathrow, Europe's busiest airport, and was in the final stages of completing updates to help restore full functionality.
Berlin airport, which was facing higher passenger numbers than usual on Monday due to the Berlin Marathon, still did not have its check-in systems restored and reported delays of over an hour for departures.
One passenger described the boarding process as akin to the early decades of commercial air travel, with handwritten boarding passes.
Brussels Airport was using iPads and laptops to check passengers in online. Of roughly 550 departing and arriving flights, 60 had to be cancelled on Monday, it said.
Dublin Airport was experiencing "minimal impact" and had some manual processes in place.

The recent airport disruptions were caused by a ransomware attack, as confirmed by the EU's cybersecurity agency.
Airports including Brussels and London Heathrow were affected, with many flights experiencing delays and cancellations.
Law enforcement is involved to investigate the malicious software, and Collins Aerospace is working with affected airports to restore systems.
Passengers at some airports had to use manual processes, such as handwritten boarding passes, to check in due to the system failures.
Experts indicate that ransomware attacks are increasingly targeting higher-profile victims, making these disruptive incidents more visible.
