WASHINGTON - The White House blamed Russia on Friday for recent cyberattacks targeting Ukraine's defense ministry and major banks.The announcement from Anne Neuberger, the White House's chief cyber official, was the most pointed attribution of responsibility for cyberattacks that unfolded as tensions escalate between Russia and Ukraine.The attacks this week, which knocked two major banks and government websites offline, were of "limited impact" since Ukrainian officials were able to quickly get their systems back up and running, but it is possible that the Russians were laying the groundwork for more destructive ones, Neuberger said.RELATED: Russian threat to invade Ukraine still 'very high,' Biden saysShe said the U.S.
