Japan Airlines (JAL) reports that personal information of up to 750,000 of its miles program customers had been compromised due to a cyber attack. Airline did not confirm if banking details had also been affected.
The leak was due to an “unauthorized access” to JAL’s database by an external server, an airline official told the local news agency Kyodo on Wednesday.
The attack affects the data of between 110,000 and 750,000 members of the airlines’ miles club that grants passengers points for flying with the airlines and gives them discounts on subsequent flights.
JAL has not yet confirmed if the customers’ passwords or banking account and card details have also been leaked.
