Yahoo News reports about the series of hacking attacks targeting the Democratic National Committee (DNC), Clinton campaign, and other US political targets starting in the summer of 2015 and continuing until at least June 2016. “Two sources familiar with the [DNC] breach said that the hackers’ reach was far more widespread than initially thought and includes personal data about big party contributors and internal ‘vetting’ evaluations that include embarrassing comments about their business dealings (as well as gossipy internal emails about the private affairs of DNC staffers). … Party officials are bracing for more damaging document dumps after Labor Day [September 7, 2016]. ‘They’re having to do serious damage control with the donors right now,’ said a party official familiar with the matter.”
Additionally, Yahoo News mentions, “There are also signs that the hackers have penetrated the personal email of some Clinton campaign staffers — at least those who were in communication with senior DNC staff members.” (Yahoo News, 7/25/2016)
