Rootkits on x64 Vista: Are they feasible?

[NewsBot]

I've noticed my desktop icons seem to be refreshing a lot more than I remember*in the past and any suspicious behavior always triggers paranoid malware fears in my mind, but that's beside the point. I was thinking about the rootkit "epidemic" and was wondering if they're still a legitimate risk on x64 Vista.

 

As far as I understand, rootkits that effectively hide their presence (i.e. not showing up in the process list, registry,*file system, etc.) require a kernel mode component to intercept queries for information that could reveal them and return a modified result with themselves omitted.

 

With x64 Vista closing the door on unsigned kernel drivers, is it still possible to have a truly stealthy rootkit (obviously moot if the rootkit is a signed)?

 

Have there been any stories of Vista rootkits in the wild?
