The media and some politicians are full force memeing this, saying USG blames Russia for the hack and leaks. The statement does not say this in the slightest.
Those aren't really weasel words.
There are weasel words if you are led to believe they are referring to the DNC/Podesta hacks. Again read carefully. To which activity are they referring to in that sentence?

I think they also do this because they don't want people to know how simple it is to conduct this kind of cyberattack. If they tell everyone you have to have your own KGB to do it, there will be less people looking into it. I believe this same strategy is why North Korea was blamed for the Sony Pictures leak.
