Online attack hits US government Web sites

Online attack hits US government Web sites:

"A botnet comprised of about 50,000 infected computers has been waging a war against U.S. government Web sites and causing headaches for businesses in the U.S. and South Korea.

The attack started Saturday, and security experts have credited it with knocking the U.S. Federal Trade Commission's (FTC's) Web site offline for parts of Monday and Tuesday. Several other government Web sites have also been targeted, including the U.S. Department of Transportation (DOT)."
