Sony Corp said it discovered a security flaw on one of the websites set up to help the 77 million users affected by April's massive data breach reset their passwords.
Sony spokesman Dan Race said the company found a security hole on a webpage that could potentially allow the hackers who had breached personal data from users in April to access the accounts using the data they had stolen.
If I had your email and your birth date I could get access to your account, Race said.
In response, Sony temporarily took down the PSN (PlayStation Network) and Qriocity password reset page, Race said.
He added that no hacking had taken place on the website and that PlayStation Network account holders can still change their passwords on their consoles at home.
This latest setback comes a day after Chief Executive Howard Stringer fired back at critics for saying Sony had not acted quickly enough to inform consumers about April's data breach.
