Japan Airlines (JAL), a member of oneworld, says that the personal information of up to 750,000 customers of its frequent flyer program had been leaked as a result of a cyber attack. The airline believes that there is no indication whether the banking details of customers have also been compromised.
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 airline claims that malware was installed on some of the airline’s computers causing the unauthorized access to the customers information.
The attack affects anywhere between 110,000 and 750,000 members of the airlines’ frequent flyer program, which allows JAL frequent flyers to earn miles towards future flights on JAL and other oneworld partners.
Japan Airlines said in its press release that there is no indication whether customers’ passwords or banking information have been compromised as a result of the cyber attack.
According to JAL’s press release:
“There is no indication that passwords and credit card numbers have been stolen and no impact on the ability for JMB members to redeem their JMB miles for awards.”
