An anonymous reader writes: Scientists have proven that a lot of people will carelessly plug in a USB drive found on the ground, exposing themselves to potential infections from malware. The researchers dropped 297 USB flash drives on a university campus and saw that in 48% of the cases, people picked them up, plugged them in, and opened files from the drive on their computers. Should such people be mocked? Would you plug in a USB drive that you found on the ground? Bruce Schneier, an American cryptographer, computer security and privacy specialist makes a good point: People get USB sticks all the time. The problem isn't that people are idiots, that they should know that a USB stick found on the street is automatically bad and a USB stick given away at a trade show is automatically good. The problem is that the OS trusts random USB sticks. The problem is that the OS will automatically run a program that can install malware from a USB stick. The problem is that it isn't safe to plug a USB stick into a computer.
