Attacking NPUs of Multiple Platforms

Explore the security vulnerabilities of Neural Processing Units (NPUs) across multiple platforms in this 37-minute Black Hat conference talk. Dive into the historical research background of NPU security and attack surfaces before examining specific vulnerabilities discovered in Samsung Exynos, Qualcomm, and Apple Silicon chipsets. Learn about code auditing and firmware reversing methodologies, common bug patterns, and witness demonstrations of code execution exploitation on Exynos NPU ARM cores and Android root exploitation using a Qualcomm NPU kernel driver bug. Gain valuable insights from security researchers Shupeng Gao, Zheng Huang, Le Wu, and Ye Zhang as they uncover the potential risks associated with NPU systems in modern devices.
