Anonymous, a group of hackers, activists and technologists, came to the fore in 2008 when they attacked the church of Scientology. Since then their coordinated collective action has come up against global corporations and supported the Arab revolutionaries, but how much do we know about who they are and what motivates them?

Six years ago Gabriella Coleman, an anthropologist, set out to study the rise of this global phenomenon just as some of its members were turning to political protest and dangerous disruption.

Coleman will be joining us in conversation with Ben Hammersley, presenter of the new BBC World News series Cybercrime with Ben Hammersley, to share her story of becoming an Anonymous confidante, interpreter, and erstwhile mouthpiece. She will be talking about the motivations of the group, the meaning of digital activism and the many facets of culture in the Internet age.

Gabriella Coleman holds the Wolfe Chair in Scientific and Technological Literacy at McGill University. Trained as a cultural anthropologist, she researches, writes about, and teaches on computer hackers and digital activism. She is the author of Coding Freedom: The Ethics and Aesthetics of Hacking and most recently Hacker, Hoaxer, Whistleblower, Spy: The Many Faces of Anonymous.
