Russia, we are told, breached the servers of the Democratic National Committee (DNC), swiped emails and other documents, and released them to the public, to alter the outcome of the U.S. presidential election.
How substantial is the evidence backing these assertions?
Hired by the Democratic National Committee to investigate unusual network activity, the security firm Crowdstrike discovered two separate intrusions on DNC servers. Crowdstrike named the two intruders Cozy Bear and Fancy Bear, in an allusion to what it felt were Russian sources. According to Crowdstrike, “Their tradecraft is superb, operational security second to none,” and “both groups were constantly going back into the environment” to change code and methods and switch command and control channels.
On what basis did Crowdstrike attribute these breaches to Russian intelligence services? The security firm claims that the techniques used were similar to those deployed in past security hacking operations that have been attributed to the same actors, while the profile of previous victims “closely mirrors the strategic interests of the Russian government. Furthermore, it appeared that the intruders were unaware of each other’s presence in the DNC system. “While you would virtually never see Western intelligence agencies going after the same target without de-confliction for fear of compromising each other’s operations,” Crowdstrike reports, “in Russia this is not an uncommon scenario.” 
Those may be indicators of Russian government culpability. But then again, perhaps not. Regarding the point about separate intruders, each operating independently of the other, that would seem to more likely indicate that the sources have nothing in common.
