Known for wearing Guy Fawkes masks, Anonymous is not one cohesive group, but a fluid movement with no leader or hierarchy. If anything, it’s a loose organization of hackers and protesters pushing for change through non-violent means, including hacktivism. Many of the hackers associated with Anonymous, however, have been arrested for several cyber crimes.

While some hackers break into systems to get money, Gary McKinnon was on another quest – finding UFO information from the government. In the 1990’s, he got his first computer and later received certification in computers. Between 2001 to 2002, McKinnon hacked into several US government agencies, including several NASA computer systems. He claims to have found documentation proving the existence of UFO’s and extraterrestrials. The US sought extradition to be tried in their courts, but the UK denied the request and would not seek charges against him, making him a free man.

They also have taken down Facebook, Instagram, Twitter, and a UK government site.
