The problem with these allegations is they always seem to have this sort of issue, as well as logical problems. Some of the things in the article don't really make any sense. For instance they state that they way they decided that Guccifer was part of the GRU is that on one occasion the IP for that Twitter account was from the GRU.
They then state that that must mean that the Russians must have forgotten to log onto their VPN first. But I mean, what? Using a dedicated VPN makes no real sense in the era of TOR, and such a mistake would have been literally impossible with TOR. It's also mentioned in the article that "The US (or a partner)" hacked at least two GRU computers. If this is the case then it's safe to assume other actors could have as well, and suddenly what exactly does a login from the GRU IP actually mean?
Or in the machines that the GRU allegedly hacked, their behavior was discovered by the presence of logs that the hackers apparently had to manually delete? State level malware does not automatically delete logs? Wow. And then they allegedly rented servers in Arizona and Illinois for illicit activities, knowing full well that their are a gazillion different domestic digital surveillance programs being carried out by the NSA? And then apparently they were exchanging emails, literally discussing theft of DNC materials, in plain text without encryption?
These things just never really make any logical sense. It simultaneously tries to paint Russians as these super hackers capable of achieving anything. And then it also shows them getting busted making mistakes that I'd like to call amateur, but that implies that these are mistakes even an amateur might reasonably make, which is probably doubtful. It's bizarre.
