According to Trion Worlds, "The database in question contained information including user names, encrypted passwords, dates of birth, email addresses, billing addresses, and the first and last four digits and expiration dates of customer credit cards."
Fortunately, the company is assuring customers that full credit card information has not been compromised in any way. However, the information that was exposed includes usernames and passwords, so that if other accounts online share that information, they should be changed immediately. They also caution users against phishing attempts using the data.
"You will notice on your next log in to our website that you will be required to change your password, and existing Mobile Authenticator users will also need to reconnect their Authenticator. When you log in, you will be prompted to provide a new password, security questions and answers, and be given the option to connect your account to our Mobile Authenticator to enhance your account’s security," the notification adds.
This is the latest in a spate of hacker intrusions onto gaming sites, which began with the disastrous PlayStation Network attack last April. This intrusion follows anof Square-Enix's database.
