Former FBI agent and Army officer Clint Watts has spent years hunting down terrorists and Russian disinformation on the Internet in his spare time. In his new book, Messing with the Enemy: Surviving in a Social Media World of Hackers, Terrorists, Russians, and Fake News, Watts documents what he learned from his experience. On Monday, he sat down with Benjamin Wittes in the Jungle Studio for a conversation about how terrorists, cybercriminals, and nation-states use online media platforms to influence people’s social and political perceptions. They talked about how Watts began tracking disinformation, what he saw, and what free societies can do to protect against it.
