In 2007, a Eurasian Youth Group utilized a cyber attack on Ukrainian President Vicktor Yushchenko. One of the largest cyber attacks was committed in Estonia when a large number of denial of services attacks were launched against government-run websites. Many speculated that the attacks were carried out in protest against a war memorial that had been taken down in Talinn.
Reports say that in 1991 a virus was invented that was meant to shut down Iraqi's anti-aircraft gunfire. Cyber attacks launched on South Korea and the United States in 2009 were believed to be from North Korea, but further investigation revealed that they actually came from someone in the United Kingdom.
The United States reported that, as a result of cyber attacks and other computer problems, the Government had to spend over one hundred million dollars to repair the damages.
