Hackers attacked SITA, the IT service provider for the majority of airlines. The SITA company deals with communication onboard airplanes, the security of the airport networks and airlines.

Hackers compromised servers storing the passenger data for airlines such as: Lufthansa, United Airlines, Singapore Airlines, All Nippon Airways, Cathay Pacific, Finnair, Japan Airlines, Jeju Air, Malaysia Airlines and New Zealand Air.

As a result of the hacking attack, SITA secured the infrastructure and contacted the affected lines. At the moment, it is not known what data was intercepted. Some of the affected airlines have issued statements of their own. According to the portal dobreprogramy, Singapore Airlines reported that the incident affects about 580,000 members of KrisFlyer and PPS. Only the membership card numbers have leaked.

Hackers were unable to obtain credit card information and other customer data such as reservations, tickets, passport numbers and email addresses due to the fact that SITA does not share this information with other Star Alliance airlines.
