It's not just the DNC and elections they're hacking. Russian hackers have also gained access to U.S. electric utility networks, claiming "hundreds of victims" in a campaign that would have enabled the hackers to cause disruptions to service at best and full blackouts at worst. The U.S. government is aware of the infiltration, and have issued intelligence indicating that they believe the campaign is actively continuing. Though the government has known about the Russian threat since 2014, this was the first time they alerted the public to the threat with so much detail.
