Metal Gear publisher Konami said that it detected 35,252 cases of unauthorized logins to its Konami ID web site. Hackers made more than 4 million attempts to access the site using unauthorized credentials between June 13 and July 7.

The company joins the same boat as Ubisoft, Nintendo, and Bohemia Interactive for companies that have been hacked recently. The Japanese video game publisher said that the unauthorized logins happened due to a leak from an “external service provider.” The company didn’t say who that was. It said that customer information may have been exposed, including names, addresses, date of birth, telephone numbers, and emails.

“No changes to customers’ personal information, or unauthorized usage of paid services, have been detected,” Konami said.

Konami has been contacting affected customers and asking them to change their passwords.

“Konami sincerely apologizes for the trouble this has caused to our valued customers,” the company said. “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.”
