The hacktivist group Anonymous “celebrated” the fifth of November (Guy Fawkes Day) through protest marches, defacing websites, and releasing the credit card information of law enforcement officers. The British holiday Guy Fawkes Day was popularized in the 2005 film "V for Vendetta", where a mask-wearing outcast overthrows a future totalitarian society. The holiday commemorates an actual historical event, where Guy Fawkes attempted to blow up the British House of Lords in 1605.
