Malaysia Airlines joins other carriers in reporting customer data compromised in the Amadeus breach, which may have affected information processed between August 2023 and September 2026.

Malaysia Airlines is working with Amadeus and relevant parties to probe the incident and assess its impact, encouraging customers to remain vigilant against suspicious communications.
