The Perfect Weapon Clip Spells Out Russia's Cyber-War Against the U.S.

How exactly did Russia hack the 2016 presidential election? This clip from the upcoming documentary The Perfect Weapon illustrates some of the ugly methods they used to falsify and amplify cultural divides to pull this off. We also hear from Hillary Clinton on just how surprised her campaign was that Vladimir Putin had such a huge investment in keeping her out of office.

The documentary is based on the book by New York Times national security correspondent David Sanger, and it's about much more than just that election. It's an unnerving look at the ways many nations around the globe are developing their abilities to use the internet to attack their enemies in subtler ways than drone missiles. 

The Perfect Weapon premieres October 16 on HBO.
