which recent compromises are they referring to?
Each statement can be proved to be correct individually. They do not have to refer to each other from a legal standpoint.
"are consistent with the methods and motivations of Russian-directed efforts"
The methods can be anything referring to hacking. Anyone who hacked the DNC would have been using methods (hacking) consistent with previous Russian hacking attempts.
Motivations? Motivations can be defined as someone wanting to take private information and making it public.
Read it like a lawyer. There is a reason why these statements are carefully crafter.
Additionally, why are you bringing in all this courtroom talk? This, and the many other statements by officials, have been directed to the general public. If the matter ever made it to court it would be the layperson's interpretation that would be key.
I fear you may not be well-versed in this area and I think it's really dangerous to be spreading such egregious misinformation.
