Do you use free wifi at places like Starbucks? I do occasionally – it’s handy and the chai is yummy. If you do, you need to be hyper aware that there are people trying to leverage that free network to get access to your private information.
This Mashable article talks about tricks like leaving a USB thumb drive on the table for people to find. You plug it in cause you’re curious – and you are oblivious to the fact that it installed a small program on you machine that can do things like give someone else control of the machine (without your knowledge), let them download info from your machine, use your machine to attack other machines on the interwebs, capture keystrokes when you’re entering your credit card info into a webform, etc etc etc. They put together a nice infographic with some details about what the bad guys do.
