The department has been warning utility executives with security clearances about the Russian threat to critical infrastructure since 2014. But on July 23, the department gave out detailed information about the intrusions publicly for the first time at an unclassified briefing for the industry. It did not provide the names of alleged victims, but said there were “hundreds.”
Hackers working for Russia claimed “hundreds of victims” last year in a major, long-running campaign that enabled them to gain control over some U.S. electric utilities, where they could have caused blackouts, the Wall Street Journal is reporting.
