Sony has warned that the names, addresses and other personal data of about 77 million people with accounts on its PlayStation Network have been stolen.
Gamers have been locked out of the network for a week, but the company has revealed that the system has been suspended since it was hacked last Wednesday.
Sony said it discovered that between April 17 and 19 an "illegal and unauthorised person" got access to people's names, addresses, email address, birthdates, usernames, passwords, logins and more. Children with accounts established by their parents also may have had their data exposed, according to Sony, which put the warning on its US PlayStation blog. The intrusion is potentially one of the biggest ever into a store of credit cards. Sony's PSN is one of the world's biggest holders of credit cards, though not as large as Amazon or eBay.
