Explore the unexpected attack vectors in baseband processors of mobile phones in this Black Hat USA 2012 conference talk. Delve into the world of baseband attacks, moving beyond the assumption of physical proximity requirements. Discover how vulnerabilities in certain baseband stack components can be exploited remotely over IP connections, potentially affecting a large number of smartphones simultaneously. Learn about NAVSTAR GPS, GPS aiding, and SUPL (Secure User Plane Location) protocols, and their role in creating new attack surfaces. Examine the implementation of A-GPS on Android devices and the potential for abuse. Gain insights into Qualcomm's gpsOne technology and the baseband bugs found. Understand the implications of TCP/IP in the baseband and receive book recommendations for further study on this critical aspect of mobile security.
