How a LinkedIn phishing scheme could empty your bank account

Headline is total link bait. Should be "how a phishing attack can empty your bank account" or the like, dragging linkedin into the headline is just lame.

Is a system that has Windows Update switched on, i.e. is up to date with security patches, at risk? That might be a cheaper way than to buy their software...

It seems to me that if you use up to date versions of the MS software stack there are numerous defenses built in that would render this attack completely moot. The fact that they don't say anything about which software versions are at risk makes this look like one of the typical sales promotion efforts of security firms rather than good info.
