But Assange himself has said the forthcoming leaks aren't about Clinton. This from ABC News:
"Mr Assange said Mrs Clinton's campaign had falsely suggested that accessing WikiLeaks data would make users vulnerable to malicious software. But he denied the release of documents related to the US election was specifically geared to damage Mrs Clinton, saying he had been misquoted.

"The material that WikiLeaks is going to publish before the end of the year is of ... a very significant moment in different directions, affecting three powerful organisations in three different states as well as ... the US election process," he said via a video link at an event marking the group's 10th anniversary. Mr Assange said the material would focus on war, weapons, oil, mass surveillance, the technology giant Google and the US election, but declined to give any details.

"There has been a misquoting of me and WikiLeaks publications ... [suggesting] we intend to harm Hillary Clinton or I intend to harm Hillary Clinton or that I don't like Hillary Clinton. All those are false," he said.
