KLM Airlines experienced a data breach involving a third-party system, exposing limited personal details of customers, including names, contact information, Flying Blue membership numbers, and email subject lines. While no sensitive data like passwords, credit card numbers, or passport details were compromised, the exposed information could be misused for targeted phishing scams. The breach did not affect core systems, and corrective measures were taken to secure the system. Customers were advised to remain vigilant against suspicious communications.

KLM and other airlines informed the customers of Flying Blue that some of their personal information was exposed following a breach of their accounts. An unauthorized entity suspiciously used these accounts and thus immediate corrective action was taken to prevent further exposure of data. However, the breached information included the names, email addresses, phone numbers, latest transactions, and Flying Blue information. Additionally, the accounts of affected customers were locked due to the breach and they were also asked to change their passwords on the KLM and Air France websites.
