4. U.S. Military Takes Shots at Castro

Compromised page: Fidel Castro, President of Cuba
Year: 2007

After discovering that the Wikipedia page of Cuban President Fidel Castro stated that Castro is an "admitted transsexual", a group of volunteer Internet investigators working for the free encyclopedia decided to try and find out who exactly was behind the hack. They couldn't believe their eyes when they discovered that the computers used to make the change belonged to Joint Task Force-Guantanamo, the U.S. military unit that runs the Camp Delta permanent detainment camp at Guantanamo Bay in Cuba. That's right—the U.S. Military hacked Wikipedia.
