Russia denied the attack, and one Russian official suggested that it was more likely a fact of local "incompetence." Estonia blamed Russia, saying that many of the attacks were coming from Russian state computer servers. Here are five more attacks that U.S. or other Western officials have blamed on Russia. The United States and NATO have never formally accused Russia of the attacks. The same hackers appeared to have deeply penetrated the servers at the State Department, the New York Times reported, and Secretary of Defense Ashton Carter said that Russian hackers had also penetrated unclassified computers at the Pentagon.
