The scam: Most people who travel for work bring their own laptops, but not printers. That's where a hotel's business center can come in handy -- and where Stickley has found an easy way to steal users' passwords.
For a TV news demonstration, Stickley installed a keylogger to a hotel's business-center computer in less than a minute. The small device, which fits in the palm of your hand, recorded the user names and passwords of hotel guests who used the computer.
The lesson: Don't type any passwords into a public computer. "It's such a huge risk," Stickley says.
