See a New York Times magazine article about the Russian "troll farm" spreading disinformation and hoaxes around the Internet. They do cleverly evil phony stuff, not unlike a latter-day Orson Welles' radio War of the Worlds.

The former KGB guy running Russia is up to new dirty tricks. We need to repay the favor, with interest. Hat tip to Lucianne.com for the link.
