South Korean Web sites were attacked again Thursday after a wave of Web site outages in the U.S. and South Korea that several officials suspect North Korea was behind. Seven sites were attacked in the third round of cyberassaults, said Ku Kyo-young, an official from the state-run Korea Communications Commission. Earlier in the day, the country’s leading computer security company, AhnLab, had warned of a new attack after analyzing a virus program that sent a flood of Internet traffic to paralyze Web sites in both South Korea and the United States.
