Russian hackers have penetrated the nation’s power grid...so the story goes

The story goes that Russian hackers have penetrated the nation’s power grid through a relatively small Vermont power company. It could be true but I find myself wondering, why is it always the "Russians"? Don't other people have the desire and the capability? It is interesting that Vermont was the target as that State produces about 40% of the power it uses through solar, wind, biomass, etc. Second, some of the balance comes from Canada. So does this hack make Canada vulnerable as well? Somehow, the whole story has an unreal ring to it. It will be interesting to see how it plays out. Hopefully not with lights out.
