Singapore Airlines booking data for 46,000 records compromised in Amadeus data breach; 620 had additional details exposed

Singapore Airlines (SIA) experienced a data breach involving the names and booking details of 46,000 customers, according to technology provider Amadeus. The breach exposed the personal information of 620 passengers, who may have had their email addresses, phone numbers, travel document details, and KrisFlyer membership numbers accessed.

Amadeus confirmed to SIA that the compromised data did not include bank account or credit card information, and the unauthorized access did not result in any changes to bookings. The airline assured customers that the incident did not involve a breach of its own IT systems and is taking steps to contact affected clients for reference number changes.

SIA stated it is informing relevant authorities about the matter and apologizes for any inconvenience caused. Other airlines affected by the breach include Cathay Pacific, Japan Airlines, Korean Air, and Malaysia Airlines. Amadeus revealed in October that certain booking-display data was accessible due to a software glitch, but there is no evidence that payment or financial data was compromised.

The Spanish firm has implemented measures to fix the vulnerability and enhanced monitoring and detection capabilities.
