It is not that someone has hacked Sony CEO's house, we are talking about the Sony Playstation Home:

Home is a virtual world for PlayStation 3 users, where they can interact with other gamers, create their own avatars, etc.

We've seen it here and this opens a totally new world for cybercrooks, as it could lead to identity theft and malware spreading. A user could even upload, download or delete any file within the Home server (!)
