(AP) A widespread computer attack that began July 4 knocked out the Web sites of the Treasury Department, the Secret Service and other U.S. government agencies, according to officials inside and outside the government.
Sites in South Korea were also affected, and South Korean intelligence officials believe the attack was carried out by North Korean or pro-Pyongyang forces.
The U.S. government Web sites, which also included those of the Federal Trade Commission and the Transportation Department, were all down at varying points over the holiday weekend and into this week. South Korean Internet sites began experiencing problems Tuesday.
U.S. officials refused to publicly discuss details of the cyber attack.
