Skype Can Expose Your Location, Researchers Say

Remember when a prankster could make himself a general nuisance by calling your home phone and quickly hanging up?

The equivalent of a prank call on Skype, the popular voice-over-Internet-Protocol service, can be much more than a nuisance. If you are logged in to Skype, a prankster – or thief or spy – can effectively track where you are and in some circumstances, what you do and even what you download, according to an experiment led by Keith Ross, a computer science professor at the Polytechnic Institute of New York University in Brooklyn.
