Anonymous, the anarchic digital collective known for everything from pranks to online vigilantism, is one of the Internet’s most notorious subcultures. Gabriella Coleman, a cultural anthropologist at McGill University and author of Hacker, Hoaxer, Whistleblower, Spy: The Many Faces of Anonymous, has spent years researching Anonymous—talking to the hackers themselves, and the law enforcement officers charged with finding them.

At 6:30 p.m. on Thursday, Dec. 11, Coleman will discuss her book with Christopher Soghoian, principal technologist at the ACLU, at a free happy hour event at the ASU Washington Center in Washington, D.C. Coleman and Soghoian will talk about what the darker corners of the Internet tell us about how we live online, and the future of digital activism.
