It seems that Sony has some seriously problems with their security. This would be like the 7th time they are hacked in the last month – month and a half. In my opinion shame on Sony, such a big company and such security issues.
Sony Music Japan was hacked through a SQL injection flaw. The hackers seems to be Lulz Security. “Luckily” they didn’t break any database that contains names, passwords or other personal information. There were 2 more database and the hackers noticed that. They purpose was not to steal information but to “embarrass Sony some more”. And i think they did it.
Sony said that right now they are working with few several professional organizations in order to fix their security issues. I hope they will manage to fix the problems in order not to loose all their clients.
