The Defense Department took as many as 1,500 computers off line because of a cyber attack, Pentagon officials said Thursday.

Few details were released about the attack, which happened Wednesday,
but Defense Secretary Robert Gates said the computer systems would be
working again soon.

Gates said the Pentagon sees hundreds of attacks a day, and this one
had no adverse impact on department operations. Employees whose
computers were affected could still use their handheld BlackBerries.

During a press briefing Gates said, “We obviously have redundant
systems in place. … There will be some administrative disruptions and
personal inconveniences.” He said the Pentagon shut the computers down
when a penetration of the system was detected, and the cause is still
being investigated.

When asked if his own e-mail account was affected, Gates revealed, “I don’t do e-mail. I’m a very low-tech person.”,8599,1636002,00.html
