Hackers got into Sony's Playstation Network and potentially got their hands on the personal info of 75 million users.
Sony lists this message on their website:
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, zip), country, email address, birthdate, PlayStation Network/Qriocity password 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 at this time that credit card data was taken, we cannot rule out the possibility. If you have provided your credit card data through PlayStation Network or Qriocity, out of an abundance of caution we are advising you that your credit card number (excluding security code) and expiration date may have been obtained.
What you should do if you have an account with their network:
• 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 number or other personally identifiable information.
• Monitor your credit report and credit card accounts.
