Researchers from security vendor Sophos say <A HREF="http://www.eweek.com/article2/0,1759,2126190,00.asp?kc=EWRSS03119TX1K0000594">a new worm targeting removable drives</A> is an example of a potential security threat for businesses.

The SillyFD-AA worm searches for removable drives such as floppy disks and USB memory sticks and creates a hidden file called autorun.inf so that a copy of the worm runs the next time the device is connected to a computer running Windows. In addition, it changes the title of Internet Explorer windows to say that the computer has been "Hacked by 1BYTE."
