WASHINGTON, June 23 - For thousands of Internet users, the offer
seemed all too alluring: revealing pictures of Jennifer Lopez,
available at a mere click of the mouse.

But the pictures never appeared. The offer was a ruse, and the click
downloaded software code that turned the user's computer into a
launching pad for Internet warfare.

On the instructions of a remote master, the software could deploy an
army of commandeered computers - known as zombies - that
simultaneously bombarded a target Web site with so many requests for
pages that it would be impossible for others to gain access to the

And all for the sake of selling a few more sports jerseys.

The facts of the case, as given by law enforcement officials, may seem
trivial: a small-time Internet merchant enlisting a fellow teenager,
in exchange for some sneakers and a watch, to disable the sites of two
rivals in the athletic jersey trade. But the method was far from rare.

Experts say hundreds of thousands of computers each week are being
added to the ranks of zombies, infected with software that makes them
susceptible to remote deployment for a variety of illicit purposes,
from overwhelming a Web site with traffic -- a so-called denial-of-
service attack -- to cracking complicated security codes. In most
instances, the user of a zombie computer is never aware that it has
been commandeered.

The networks of zombie computers are used for a variety of purposes,
from attacking Web sites of companies and government agencies to
generating huge batches of spam e-mail. In some cases, experts say,
the spam messages are used by fraud artists, known as phishers, to try
to trick computer users into giving confidential information, like
bank-account passwords and Social Security numbers.

Officials at the F.B.I. and the Justice Department say their inquiries
on the zombie networks are exposing serious vulnerabilities in the
Internet that could be exploited more widely by saboteurs to bring
down Web sites or online messaging systems. One case under
investigation, officials say, may involve as many as 300,000 zombie

While the use of zombie computers to launch attacks is not new, such
episodes are on the rise, and investigators say they are devoting more
resources to such cases. Many investigations remain confidential, they
say, because companies are hesitant to acknowledge they have been
targets, fearful of undermining their customers' confidence.
