Anonymous - Internet rebels

The loose-knit hackivist collective known as Anonymous started as a culture of pranking and trolling on the Internet, but in the last few years the cooperative has taken a much more serious turn. Anonymous has taken down multiple government websites around the world and is now seen by many as cyber terrorists. People credit the group for pushing the boundaries of what can be done on the web and Parmy Olson, Forbes' London bureau chief, spent one year researching them while working on her new book, We Are Anonymous. She joins us with more about the Internet sub-culture.
