Here is the definitive book on the worldwide movement of hackers, pranksters, and activists that operates under the name Anonymous, by the woman the <i>Chronicle of Higher Education</i> calls “the leading interpreter of digital insurgency” and the <i>Huffington Post</i> says “knows all of Anonymous’ deepest, darkest secrets.” Half a dozen years ago, anthropologist Gabriella Coleman set out to study the rise of this global collective just as some of its adherents were turning to political protest and disruption (before Anonymous shot to fame as a key player in the Arab Spring and Occupy Wall Street). She ended up becoming so closely connected to Anonymous that some Anons claimed her as “their scholar.” <i>Hacker, Hoaxer, Whistleblower, Spy</i> brims with detail from inside a mysterious subculture, including chats with imprisoned hacker Jeremy Hammond and the hacker who helped put him away, Hector “Sabu” Monsegur. It’s a beautifully written book, with fascinating insights into the meaning of digital activism and little understood facets of culture in the Internet age, such as the histories of “trolling” and “the lulz.”
