Exploitation of a Modern Smartphone Baseband

Exploitation of a Modern Smartphone Baseband

Explore the intricacies of modern smartphone baseband security in this 41-minute Black Hat conference talk. Delve into the design and security countermeasures of smartphone basebands, learn techniques for identifying memory corruption bugs, and discover methods for exploiting vulnerabilities. Gain insights into the relationship between the Application Processor (AP) running the OS and apps, and the baseband running a Real-Time Operating System (RTOS). Examine radio technologies, CDMA network setup, and the process of hacking into the machine to reach vulnerable components. Witness the exploitation of a potential stack overflow in the baseband and understand vendor responses to such security issues.
