Impacted airports include London Heathrow, Brussels Airport and Berlin Brandenburg Airport, as well as Dublin Airport, where multiple airlines continue to use manual-based processes to check in passengers and luggage.
“Although this arrest is a positive step, the investigation into this incident is in its early stages and remains ongoing,” said Paul Foster, head of the U.K.’s National Crime Agency’s cybercrime unit. Police arrested the man in West Sussex. Authorities released him on conditional bail.
U.S.-headquartered RTX Corporation, formerly Raytheon Technologies, develops through its Collins Aerospace subsidiary check-in and boarding software known as Muse used by numerous airlines to handle their check-in and boarding processes. It fell victim to a ransomware attack late Friday.
No ransomware group has publicly claimed responsibility for the disruption. British cybersecurity expert Kevin Beaumont said the crypto-locker used in the hack “is a variant of HardBit ransomware, which doesn’t have a portal and is incredibly basic.” Whether the group that developed HardBit or its affiliates, or someone else who purchased or otherwise obtained the code might be behind the Collins attack isn’t clear.
The Muse system allows multiple airlines to share check-in desks and boarding gate positions. Operations at Brussels Airport on Wednesday continued to be impacted, with 6% of flights being canceled, 7sur7 reported.
Flight cancellations and delays have been reported at Berlin Brandenburg on Wednesday, local news outlet Watson reported.
“The company has informed us that it can take several more days to provide a functional system,” a Berlin Brandenburg spokesperson said. “This is very unfortunate and surprised us. Exactly when everything will work properly again is not foreseeable.”
Disruption at London Heathrow Airport eased significantly over the weekend. “The vast majority of flights at Heathrow are operating as normal,” the airport said. “We are supporting affected airlines with their contingencies and have deployed additional colleagues in terminals to assist passengers,” it added.
The latest incident is a “textbook supply chain attack,” as the aviation industry runs on “an intricate web of legacy systems and providers,” said David Mound, head of research and community at Shinobi Security.
“The airports weren’t direcly compromised. A weak link in their technology ecosystem was exploited, which is a stark reminder that security is only as strong as the most vulnerable vendor in your supply chain,” Mound said.
