Today i got a message from gamigo with the subject "Important: Password Change"

We have regrettably been forced to reset your password!
 

Dear gamigo User,
We regret to inform you that our database was subject to an attack in the last few days. The intruder(s) managed to acquire (alias) user names and gamigo user passwords. An excerpt from these was published in the gamigo forums.

We detected the attack and are working to the utmost of our resources to repair the damage and to determine how it happened. We are leaving no stone unturned in our efforts.

Your character data, including items, is safely stored on the backup and remains available to you.

We cannot rule out that the intruder(s) is/are still in possession of additional personal data, although to date we have received no report of any fraudulent use.

To prevent any unauthorized access to your account, we have reset all passwords for the gamigo Account System and for all gamigo games!   

After looking into the internet i found out that it seems to be real. At http://ixplizit.wordpress.com/2012/03/02/gamigo-com-got-hacked/ you find some pics that they stored the passwords in plain text. I do not understand why anyone would do this these days.
