Another Sony Rootkit?

This one has to do with jump drives that have fingerprint access security features.  It's so secure that it hides its drivers in a rootkit in C:\windows.  The folder is invisible to the operating system but reports are that hackers can use it to hide malicious files.  The problem is not that Sony wants to protect its authentication files but that others can get to the folder.  At the same time, if someone can get to the folder, can't they tamper with authentication files?
