# How to intercept your bosses print jobs name: Thomas Watson Location: Copenhagen, Denmark # How to intercept your bosses print jobs Bonjour/Zeroconf is used to automatically configure and connect to networked devices like printers on a LAN and is widely deployed in offices and homes. This talk gives an introduction to the Zeroconf standard and shows how it’s vulnerable to a man-in-the-middle attack. The talk will show how Zeroconf can be exploited to allow a man-in-the-middle attack on any Zeroconf enabled device. This allows you to intercept anything from print jobs to admin panel passwords.
