Report: Russian hackers breached DNC computer network, stole opposition research on Trump

Russian hackers breached the Democratic National Committee's computer network and stole the entire file of opposition research on presumptive Republican presidential nominee Donald Trump, according to a Tuesday report in The Washington Post.

According to The Post, some Russian hackers had access to the DNC for over a year, and had access to chats and emails between staffers. CEO Amy Dacey said that IT noticed strange network activity in April.

The Post reported that the hackers avoidance of donor information indicates that the breach was likely the work of "traditional espionage."

Political organizations like the DNC and its counterpart the Republican National Committee often spend months building out opposition research files for opposing candidates, which are typically culled from past public statements and actions.

Both the DNC and the Trump campaign did not immediately respond to Business Insider's request for comment.
