5. Gary McKinnon
After hacking into more than 90 US military and NASA computers, Gary McKinnon said he was just trying to find some information on the UFOs. The truth was somewhat different. He deleted crucial system files from computers and caused a crash of several military networks. After 9/11 attacks, he also targeted Earle Naval Weapons Station, disabling their network and immobilizing monition deliveries to the US Navy’s Atlantic Fleet.
