The company operates passenger processing systems for airlines and Singapore Air’s Krisflyer and Priority Passenger Service data was affected through its membership in the Star Alliance, the report said. The information in the data breach is limited to membership numbers, tier statuses and names in some cases. The airline told the newspaper that none of its own information technology systems have been affected, and it is reaching out to all KrisFlyer and Priority Passenger Service members to inform them about the incident. SITA has contacted affected customers and all related organisations, the report said.
