[Hermite15]

don't know what to think of that, someone posted about it on another forum; this is supposed to be the first rootkit being able to attack 64 bit Windows:

TDL3 rootkit x64 goes in the wild

They actually built a nice gift for every security vendor, because TDL3 has been updated and this time this is a major update; the rootkit is now able to infect 64 bit versions of Microsoft Windows operating system

This is scary.

This is scary.

Did you think they wouldn't achieve that?
I don't expect "final win" in security field...

I am surprised it took so long - TDSSKiller works on 64 bit systems as does AD_13s MBR so we have a toehold against it

I knew that some day this would happen but not so soon.

I guess they've been waiting until it becomes worth it, like most OEM systems ship with Seven/64 now well if you consider the real start of 64 bit Windows being Vista, shipping with patchguard and driver signature check, it still took three and a half years
