President Obama has ordered a review of hacking by Russia aimed at influencing U.S. elections. The review will focus on hacks perpetrated during the 2016 campaign, but will also include malicious cyber activity going all the way back to 2008. Obama expects to receive a report before he leaves office on January 20. In response, Russia denied claims made by the U.S. and called for evidence of its involvement. In October, the Intelligence Community said it was "confident" that Russia was behind hacks of government and political entities.
