Several days ago, half jokingly, Edward Snowden gave the best advice on how to determine whether Russia was indeed, as the media has already decided, behind the hack of first the Democratic National Committee, then the Democratic Congressional Campaign Committee and, as of last night, the Hillary presidential campaign itself. This is what Snowden said in a July 25 tweet: "Evidence that could publicly attribute responsibility for the DNC hack certainly exists at #NSA, but DNI traditionally objects to sharing. The aversion to sharing #NSA evidence is fear of revealing "sources and methods" of intel collection, but #XKEYSCORE is now publicly known."

It appears that the NSA has taken up Snowden on his advce, because as ABC reports, U.S. government hackers at the National Security Agency are now targeting Russian government-linked hacking teams "to see once and for all if they're responsible for the massive breach at the Democratic National Committee." ABC cited three former senior intelligence officials. It's a job that the current head of the NSA's elite hacking unit said they've been called on to do many times before, ABC notes.
