Explore radio hacking techniques and their applications in exploiting wirelessly controlled devices like gates, garages, and cars in this 51-minute conference talk from AppSec California 2016. Delve into the vulnerabilities of GSM-controlled vehicles, RF-based keyfobs, and mobile device implementations. Learn about key-space reduction attacks on fixed codes, advanced "code grabbers" for encrypted and rolling codes, and methods to exploit mobile devices with poor SSL implementations. Discover how to use low-cost tools such as RTL-SDR, GNU Radio, HackRF, Arduino, and even Mattel toys for radio hacking. Gain insights into protecting against these vulnerabilities and acquire knowledge about various tools for hardware, car, and RF research. By the end of the talk, understand how to build and use inexpensive devices for investigating wireless security in vehicles and physical access systems.
