The Washington Post's online arm has apparently been caught in a metadata gaffe that 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.
