Core Escalation - Unleashing the Power of Cross-Core Attacks on Heterogeneous System
Explore the vulnerabilities of modern smartphone SoCs in this 34-minute Black Hat conference talk. Delve into the complexities of multi-core architectures, including Application Processors, baseband, camera, sensor hubs, and low power management modules. Examine how traditional permission control and security boundary management fall short in protecting against cross-core attacks. Analyze real-world examples of compromised mobile devices through WiFi and baseband DMA attacks. Gain insights into the limitations of Exception Level (EL) based solutions like ARM Trustzone when facing threats from multiple cores. Understand the potential risks of inadequately defended cores compromising entire SoC systems. Learn about the evolving landscape of smartphone security and the need for comprehensive, multi-core protection strategies.
