The personal data of 1.29 million people has been stolen from computing firm Sega after they confirmed an attack on their systems.
Sega confirmed on Friday that hackers had stolen email addresses and dates of birth from their Sega Pass database.
They were quick to stress though that payment information, including credit card numbers, had not be stolen and remained safe.
"We are deeply sorry for causing trouble to our customers," Sega spokeswoman Yoko Nagasawa said.
"We want to work on strengthening security."
Ms Nagasawa added that it was not yet known when the Sega Pass online network could be restarted.
Sega issued an email to their Sega Pass users on Friday explaining the situation.
"Over the last 24 hours we have identified that unauthorised entry was gained to our Sega Pass database," the email said.
"We immediately took the appropriate action to protect our consumers' data and isolate the location of the breach. We have launched an investigation into the extent of the breach of our public systems."
The firm has reset all passwords and is urging their customers to change their log-in details as an extra security measure.
