They probably do, but those instances are not noticed and therefore don't make the news.

Maybe it's someone in the US trying to trick people into thinking it was Russia who did it.

My guess is that someone attempted to log in over Tor and they got unlucky with a Russian exit node.

Or maybe I'm giving this situation too much credit and we should call a spade by its name.

They’re bragging.

Yeah, I think this should be seriously investigated, but that detail struck me as not making sense.

They didn’t think they even needed to do that.

The door is supposed to be completely open.
