"Many of the hundreds of millions of people around the world who swap music, movies and other digital content on their personal computers over the Internet have inadvertently put themselves at risk of identity theft," according to The Wall Street Journal. "The problem typically arises when users set up file-sharing software and create a folder for their downloads in the same location as their personal files. In the latest incident, a Seattle man this week pleaded guilty to charges of identity theft for using LimeWire to steal tax forms, credit reports and student-loan applications from the computers of more than 50 people."
