Electronic Arts has denied reports of their Origin database being hacked.
Users started reporting that their accounts were being stolen on the official forum of Origin.
"At this point, we have no reason to believe there has been any intrusion into our Origin database," said an EA representative, IGN reported.
Users claimed they were receiving emails which said that their username and password were being changed without their authorization.
"Anytime a player has a question about the security of his or her account or personal data, we take it very seriously and take all possible steps to help. For any customer who cannot access their Origin account for any reason, we ask them to please contact Origin Help or EA's customer experience group at help.ea.com."
"The robust security measures in place to protect Origin users accounts are constantly being expanded and upgraded, and we also strongly recommend customers take the protective steps of using strong passwords and changing passwords often," said EA, Eurogamer reported.
Users were locked out of their own accounts. They reportedly had a bad experience when they contacted EA support, as the company did not know anything about the issue.
Some users reported that their accounts were changed to a Russian address (.ru).
It is still unclear as to how the hack took place, or if the accounts were stolen due to phishing or social engineering.
Origin was earlier known as EA Store.
