Amadeus data breach affects 46,000 Singapore Airlines bookings

Dhaka: Singapore Airlines has disclosed that approximately 46,000 booking records may have been exposed in a cybersecurity incident involving Amadeus, its reservation technology provider.

The airline said on November 3 that the potentially compromised information included passengers' names, booking reference numbers, travel itineraries and booking classes.

In around 620 records, additional information such as email addresses, telephone numbers, travel document details and KrisFlyer membership numbers may also have been accessed.

Singapore Airlines said Amadeus had confirmed that no bank account or credit card information was exposed and that existing reservations had not been altered. The carrier also emphasized that its own information technology systems were not breached.

As a precaution, the airline is contacting affected passengers with upcoming trips to arrange changes to their booking reference numbers.

The incident has also affected other international carriers, including Cathay Pacific, Japan Airlines, Asiana Airlines and Malaysia Airlines, which have reported potential exposure of customer information linked to the Amadeus breach.

Amadeus said it had identified a vulnerability in a travel booking display environment but did not disclose the number of customers potentially affected.

The incident has renewed concerns over the security of passenger information handled by third-party technology providers across the global aviation industry.
