Malaysia Airlines Customers May Be Affected By Amadeus Data Breach

Malaysia Airlines has issued a warning that some customer information may have been compromised due to a cybersecurity incident involving Amadeus, a leading global provider of airline reservation and distribution technology. The airline disclosed that the incident, which occurred between August 2023 and September 2026, may have impacted customer data processed through Amadeus.

Malaysia Airlines is currently collaborating with Amadeus and relevant authorities to investigate the matter and assess its potential ramifications. While the airline reassured passengers that its own IT systems were not breached and there is no evidence of financial information being accessed, it advised travelers to remain cautious of unsolicited communications, especially those requesting personal or financial details.

Malaysia Airlines is not the only carrier affected by the incident. Other airlines, including Cathay Pacific, Japan Airlines, and Asiana Airlines, have reported being impacted. Cathay Pacific and Japan Airlines have provided estimates of the number of bookings and customers affected, with Cathay Pacific mentioning 53,000 bookings and 92,000 customers, and Japan Airlines disclosing information related to approximately 53,000 bookings and 92,000 customers.

Amadeus revealed last month that it had experienced unauthorized access to its passenger reservation systems, attributing the breach to a vulnerability in a travel booking display environment. However, the company did not disclose the exact number of customers potentially impacted.
