SITA, a multinational company that specializes in air transport communications and IT, this week confirmed falling victim to a cyberattack that appears to have impacted multiple airlines around the world.

SITA said on Thursday that the attack, which it described as “highly sophisticated,” affected certain passenger data stored on servers of SITA Passenger Service System (PSS) Inc., which operates passenger processing systems for airlines.

“After confirmation of the seriousness of the data security incident on February 24, 2021, SITA took immediate action to contact affected SITA PSS customers and all related organizations,” the company said in a statement.

It added, “SITA acted swiftly and initiated targeted containment measures. The matter remains under continued investigation by SITA’s Security Incident Response Team with the support of leading external experts in cyber-security.”

Several airlines have confirmed being affected by the breach, including Singapore Airlines, Malaysia Airlines, Finland’s Finnair, Jeju Air in South Korean, and Air New Zealand.

Singapore Airlines told customers that it’s not a customer of the SITA PSS, but since at least one of the 26 Star Alliance member airlines is a PSS customer, SITA has access to some frequent flyer program data for all Star Alliance airlines. Star Alliance is the world’s largest global airline network.

“All Star Alliance member airlines provide a restricted set of frequent flyer programme data to the alliance, which is then sent on to other member airlines to reside in their respective passenger service systems. This data transfer is necessary to enable verification of the membership tier status, and to accord to member airlines’ customers the relevant benefits while travelling,” Singapore Airlines explained.

Singapore Airlines said roughly 580,000 members of its KrisFlyer and PPS programs are affected by the breach at SITA.

Based on the notifications sent by impacted airlines to their customers, only information such as name, tier status and membership number has been compromised. However, this type of information can still be useful for targeted phishing attacks. There is no indication at this time that passwords, payment card information, passport numbers, reservations, or contact information has been compromised.

According to its website, SITA has more than 2,500 customers and has a presence in over 1,000 airports across 200 countries and territories.
