Attackers hijack federal computers
Hundreds of powerful computers at the Defense Department and U.S. Senate were hijacked by attackers who used them to send spam e-mail, federal authorities say.
The use of government computers was uncovered during the Justice Department's recent cybercrime crackdown. It adds another wrinkle to the use of so-called zombie PCs, which number in the millions and have bedeviled consumers and universities the past year.
Attackers gain secret control of the computers by sending e-mail viruses and worms or by planting software code on Web sites.
