Sony has suspended 93,000 user accounts on several of its gaming and entertainment networks after unauthorized login attempts on those accounts, it said Wednesday.
The attempted logins occured on the PlayStation Network, Sony Entertainment Network, and networks run by Sony Online Entertainment.
A small number of the logins had been successful, the company said. The attempts occurred between Oct. 7 and Oct. 10, and Sony said that they appeared to use login and password information obtained from a separate company.
Sony said it is not aware of any breach of its own databases in relation to the login attempts, and no credit information had been leaked as a result of them.
The company has sent emails to customers with frozen accounts requesting them to change their passwords, it said.
