Malaysia Airlines becomes latest carrier hit by Amadeus booking system data breach
Malaysia Airlines said Sunday that some customer information may have been compromised in a cybersecurity incident involving Amadeus, a global travel technology provider based in Spain whose systems support airline reservations and passenger services.
Malaysia Airlines has joined a growing list of airlines affected by a data breach in the Amadeus booking system, according to recent reports. The incident, which may have impacted customer information from August 2023 to September 2026, has prompted Malaysia's national carrier to collaborate with Amadeus and other parties to assess the situation.
While Malaysia Airlines affirmed that its own IT infrastructure remained unbreached and that there was no evidence of unauthorized access to financial data, the company cautioned customers to remain vigilant against phishing attempts, especially those soliciting personal or financial information. Amadeus disclosed a vulnerability in a travel booking display environment, though the airline declined to provide an estimate of the number of customers potentially affected.
Other carriers, including Cathay Pacific and Japan Airlines, have also reported data breaches linked to the Amadeus incident, with Cathay Pacific citing 53,000 affected bookings and Japan Airlines reporting 92,000 impacted customers.
