IBM announced the results of its 2004 Global Business Security Index Report and provided an early look at potential security threats in 2005. IBM's report is predicting a trend this year that may include the aggressive spread of viruses and worms to handheld devices, cell phones, wireless networks, and embedded computers, which include car and satellite communication systems.

According to the report, during the latter part of 2004, a growing number of viruses aimed at PDAs and other mobile devices, such as the Cabir worm, were released. It is likely that such worms will be used by copycats and may spur an epidemic of viruses aimed at mobile devices.
