Anonymous source burned by metadata

If you take digital pictures you may know that the photographs can have information embedded in them, including the time, place and the camera's settings when the picture was taken. eWeek writes about how such "metadata" left in a Washington Post photograph published online "exposed the whereabouts of a 21-year-old hacker who confessed to controlling thousands of compromised PCs for malicious use." "The hacker agreed be interviewed by Washington Post reporter Brian Krebs on the condition that he not be identified by name or home town, but when the article was posted on the newspaper's Web site, an accompanying photograph included metadata that pinpointed the location to Roland, Okla., a small town with a population of 2,842," eWeek says. The article says Slashdot contributors made the discovery, with one Slashdotter wondering "how many other news stories might have very much unintended data leaks through metadata tags in images. Possibly quite a hell of a lot."
