TOKYO: Major Japanese air carriers All Nippon Airways and Japan Airlines have found data on about 1 million and 920,000 of their customers, respectively, to have been compromised, it was learned Saturday.
According to ANA, the data breach is linked to a cyberattack on Swiss air transportation information technology firm Sita. ANA shares frequent flyer membership data with other Star Alliance members through Sita’s servers.
The affected ANA customers are ANA Mileage Club premium members. Their names, membership numbers and membership status were leaked, while their passwords and credit card numbers were not.
