I’m not sure how real this is, but the concept of a virus affecting the firmware of a USB device is a bit creepy. The gist of the article is that it is possible to plant malware in any usb device. The issue is that the USB devices are not protected by signatures in their firmware (Programming that lets the USB device talk with your computer).
Oh well, another thing to worry about .
