WASHINGTON—The Trump administration on Thursday blamed the Russian government for a campaign of cyber attacks stretching back at least two years that targeted the U.S. power grid, marking the first time the United States has publicly accused Moscow of hacking into American energy infrastructure.
Beginning in March 2016, or possibly earlier, Russian government hackers sought to penetrate multiple U.S. critical infrastructure sectors, including energy, nuclear, commercial facilities, water, aviation and manufacturing, according to a U.S. security alert published Thursday.
