(Bloomberg) -- A leading Japanese matchmaking app was hacked, likely exposing the personal information of more than 1.7 million account holders, in the latest high-profile online attack. Net Marketing Co., which runs the Omiai dating app, said that it found evidence of unauthorized access to its servers in April. Among the data exposed were photos of ID used to confirm the age of users, including driversâ licenses, insurance cards and passports. Credit card data was not leaked in the hack, the firm said on Friday, adding that it had yet to confirm misappropriation of the personal information.
