More than half a million Singapore Airlines’ frequent flyer members have had their personal data compromised.
The data breach came via the passenger service system servers of aviation tech company SITA.
"While SIA is not a customer of the SITA PSS, this breach of the SITA PSS server has affected some KrisFlyer and PPS members," the airline said.
The SITA connection to Singapore Airlines is through the Star Alliance airline network.
"The information involved is limited to the membership number and tier status and, in some cases, membership name, as this is the full extent of the frequent flyer data that Singapore Airlines shares with other Star Alliance member airlines for this data transfer," SIA said.
The breach doesn’t involve KrisFlyer passwords or credit card information.
None of the airlines IT systems were impacted.
"The protection of our customers’ personal data is of utmost importance to Singapore Airlines, and we sincerely regret the incident."
SITA confirmed the cyber-attack late last month and said it was ‘a highly sophisticated attack.’
It is still being investigated, SITA said.
