In a recent study, researchers found that two thirds of lost USB devices contained malware.

"The experiment was done by antivirus firm Sophos, which acquired three bags of USB sticks lost by commuters on trains in the Greater Sydney metro area at an auction organized by the Rail Corporation New South Wales," writes ITworld's Lucian Constantin.

"According to Sophos, the analysis was performed on 50 USB sticks that ranged from 256MB to 8GB in size and revealed that 33, or 66 percent, of them were infected, some with multiple types of malware," Constantin writes.
