Anonymous

Anonymous is the term used to describe a large, multinational group of computer users who are skilled in their abilities to manipulate the Internet in drastic ways to prove a point. Created in 2003, it is dedicated against the ideas of Internet censorship and surveillance, and has attacked several important corporations and even governmental websites digitally. There is no defined set of leadership or ranks among the group, so it literally assumes its name "Anonymous" as there is no way to determine who belongs to the group. Many of their activities have been associated with protests: the SOPA (Stop Only Piracy Act) was reacted by attacks on several US official websites, participated in the Occupy Wall Street Protests, supported the Kony 2012 movement while accusing the way it was being run as propaganda, and (possibly most famously) took down the PlayStation network. They have even come into conflict with non-government organizations like the Mexican Los Zetas Cartel, although nothing escalated out of that specific incident.
