Russia’s hacking of emails from Hillary Clinton’s campaign chairman and the Democratic National Committee during the 2016 presidential campaign. In that case, once they had the emails, the Russians used trolls to spread and spin the material, and built an echo chamber to widen its effect.

The Russian attacks on Burisma appear to be running parallel to an effort by Russian spies in Ukraine to dig up information in the analog world that could embarrass the Bidens, according to an American security official, who spoke on the condition of anonymity to discuss sensitive intelligence. The spies, the official said, are trying to penetrate Burisma and working sources in the Ukrainian government in search of emails, financial records and legal documents.
