Mueller on Friday indicted 12 Russian military officers for hacking groups affiliated with the Democrat Party, including the Democratic National Committee (DNC) and Hillary Clinton's campaign.
DCLeaks was used to distribute documents pilfered during the hacks and Guccifer 2.0 posed as a Romanian hacker inspired by notorious hacker Guccifer.
Guccifer 2.0 drew attention during the 2016 presidential election when Donald Trump surrogate Roger Stone said he was in touch with the hacker.
The latest round of indictments in Mueller's Russian probe referred to an unidentified U.S. person who was in contact with Guccifer 2.0 and members of the Trump campaign. On Saturday, Stone said he was likely that person. The indictment recounts a message between Guccifer 2.0 and the U.S. National in which the former says it “would be a great pleasure” to help and asks “What do u think about the info on the turnout model for the democrats entire presidential campaign.”
The latter answers, “Pretty standard.”
