Konami has revealed that earlier this week it detected 35,252 cases of unauthorized logins to its Konami ID site from around four million attempts between June 13 and July 7.
The logins were made using usernames and password “that appear to have been leaked from an external service provider,” the publisher explained. Information that has been potentially exposed includes names, addresses, dates of birth, telephone numbers, and email address.
“No changes to customers’ personal information, or unauthorized usage of paid services, have been detected,” Konami said in a statement. “Konami sincerely apologizes for the trouble this has caused to our valued customers… Konami has strengthened its security and raised its monitoring level, and measures have been taken to ensure that IDs and passwords involved in these unauthorized logins can no longer be used to log in.”
Users that have been affected by the breach have been sent emails explaining the situation with password reset links. Konami is advising all users to change their password as soon as possible.
