U.S. authorities say they are eyeing North Korea as the origin of the cyber attack that overwhelmed government Web sites in the United States and South Korea. But they warned it will be difficult to quickly identify the attackers, Associated Press reported.
Internet addresses have been traced to North Korea, three officials said, but they added that that does not suggest the attack involved the Pyongyang government. The officials spoke on condition of anonymity because of the sensitivity of the matter.
The Internet attack, which stretched on for days beginning over the July 4 holiday weekend, targeted dozens of government and private sites and underscored how unevenly prepared the U.S. government is to block such assaults.
