Korean Internet users are on alert after Sony was hit by the biggest hacker attack in its history. Sony's U.S. affiliate on Wednesday said an internal investigation shows the hacker attack resulted in the leak of the personal information of 77 million users of the online game service PlayStation Network and the online music and video service Qriocity.
The company admitted it is possible that credit card information was leaked. The hackers stole not only basic personal information such as name, ID, password, and date of birth, but the details of financial transactions and billing addresses.
An estimated 230,000 Koreans play games on PSN, and their information is likely to have fallen into the hands of overseas hackers. It is highly likely that the hackers stole credit card information used for purchasing online games. Those registered with PSN are advised to check for any suspicious credit card payments made overseas.
The Korea Communications Commission also urged users of the gaming site to change their password immediately as well as for other websites where they use the same password.
Most of the people whose information was leaked are in the U.S., which has 36 million users, and Europe, which has 32 million. There are about 9 million users in Asia, mostly in Japan. Sony temporarily suspended PSN and Qriocity services from April 20.
