DefCon Wall of Sheep presents a real time view of usernames and passwords sent in the clear over DefCon WiFi in Riviera Hotel. The conference booklet warns about using any password-protected sites that ask for the password in the clear, and the Wall of Sheep just accentuates that warning. They do mask the second half of the password, though, to protect the innocent.

Biggest surprise? Large number of visits to myspace.com at any time.
