Identity Theft: Guided Tour of Hacker Chat Room

Steven Levitt and Stephen Dubner, co-authors of the book Freakonomics, also maintain a blog.

There, they have a recent post about identity theft that points to a number of articles and studies on the topic, including a New York Times Magazine column of theirs in this weekend's issue that offers a "guided tour of a hacker chat room where credit-card numbers, passwords, and PIN’s are bought and sold".
