Advocating freedom, fairness and justice, Anonymous became known to the public in a 2007 Los Angeles TV report and has since claimed responsibility for numerous break-ins. In 2010, it hacked PayPal, MasterCard and Visa for no longer accepting donations to WikiLeaks after the site disclosed U.S. military documents. See WikiLeaks.

The Guy Fawkes Mask
Anonymous adopted a mask created to honor Guy Fawkes as a symbol of rebellion in the 2005 movie "V for Vendetta." Fawkes was in charge of the gunpowder in a failed 1605 plot to blow up Parliament and restore a Catholic monarchy to England. About to be hanged to near death and then disemboweled, Fawkes jumped from the gallows and did himself in. In 1606, Parliament turned the foiled Gunpowder Plot into a national holiday.
