WASHINGTON, April 8 (UPI) -- Russia was behind a 2014 cyberattack on the White House, officials said, adding no classified information was leaked.
"This report is not referring to a new incident. It is speculating on the attribution of the activity of concern on the unclassified EOP (Executive Office of the President) network that the White House disclosed last year," National Security Council spokesman Mark Stroh said Tuesday in a statement. "Any such activity is something we take very seriously. In this case, as we made clear at the time, we took immediate measures to evaluate and mitigate the activity."
