Multiplexed Wired Attack Surfaces presented at BlackHatUSA 2013

by Michael Ossmann, Kyle Osborn,

Summary : Manufacturers of mobile devices often multiplex several wired interfaces onto a single connector. Some of these interfaces, probably intended for test and development, are still enabled when the devices ship. We'll show you how you can get a shell on a popular mobile phone via its USB port without using a USB connection and we will release an open source tool for exploring multiplexed wired interfaces.
