The United States Computer Emergency Readiness Team, US-CERT, was busy undoing the destruction endured after the U.S was cyber attacked over the Fourth of July weekend. The lead suspect behind this attack is North Korea, especially since South Korean government websites were also attacked.
An Examiner.com article reports states that North Korea is becoming more and more of a threat each day. "Kim Jong-il understands that a shut-down of the internet, while no lives are lost, will spell economic disaster for the United States."
