Burger King Japan operator reports breach exposing over 11 million user records

Burger King's Japan franchise announced that a server handling data from its official mobile application was accessed without permission, compromising personal information of over 11 million users. The exposed records contain customers' names, dates of birth, email addresses, telephone numbers and gender, but do not include credit-card details, which the company does not retain. Officials have not yet detected any misuse of the data and are conducting a thorough investigation.

The incident adds to a series of recent cyber-security breaches in Japan, which have also hit a car-sharing service, a major railway company and a motorcycle manufacturer. Earlier, a travel agency revealed a passport data leak from the previous year. Authorities and the company are working to assess the full impact of the breach.
