Sony have revealed that the recent issues with its PSN service may have led to users' details being accessed by hackers.
In a post of the PlayStation blog, Sony have revealed details of the leaked information:
"Although we are still investigating the details of this incident, we believe that an unauthorized person has obtained the following information that you provided: name, address (city, state/province, zip or postal code), country, email address, birthdate, PlayStation Network/Qriocity passwords and login, and handle/PSN online ID. It is also possible that your profile data, including purchase history and billing address (city, state, zip), and your PlayStation Network/Qriocity password security answers may have been obtained. If you have authorized a sub-account for your dependent, the same data with respect to your dependent may have been obtained. While there is no evidence that credit card data was taken at this time, we cannot rule out the possibility. If you have provided your credit card data through PlayStation Network or Qriocity, to be on the safe side we are advising you that your credit card number (excluding security code) and expiration date may also have been obtained."
It continues: "For your security, we encourage you to be especially aware of email, telephone, and postal mail scams that ask for personal or sensitive information. Sony will not contact you in any way, including by email, asking for your credit card number, social security, tax identification or similar number or other personally identifiable information. If you are asked for this information, you can be confident Sony is not the entity asking. When the PlayStation Network and Qriocity services are fully restored, we strongly recommend that you log on and change your password. Additionally, if you use your PlayStation Network or Qriocity user name or password for other unrelated services or accounts, we strongly recommend that you change them, as well."
They have not released any details of how many users are affected.
