The U.S. government for the first time on Friday formally accused Russia of a campaign of cyber attacks against Democratic Party organizations ahead of the Nov. 8 presidential election.As far as the "cui bono" question, I'll set that aside, because the answer is rather plain.
"We believe, based on the scope and sensitivity of these efforts, that only Russia's senior-most officials could have authorized these activities," a U.S. government statement said on Friday about hacking of political groups.
"These thefts and disclosures are intended to interfere with the U.S. election process."
No doubt that Wikileaks will soon start releasing stuff that they got from the Russians. A wise person will put no stock in any of it.
The Russians have a decades-long record of document forgery. They've forged emails. There was a story, a long time ago, that an American reporter in Europe found an envelope in his car; the envelope contained documents that were damning to Zbigniew Brzezinski, then the National Security Advisor. The newspaper vetted the documents carefully and concluded that they were forged.
Whatever Wikileaks releases to try and sway the election should be regarded as Russian forgeries until proven otherwise.
