In this episode of Below the Surface, host Paul Asadoorian is joined by co-hosts Larry Pesci, Joshua Marpet, and Vlad Babkin to delve into the complexities of hardware supply chain security. The discussion is sparked by a presentation from Andrew 'Bunny' Wong at Black Hat Asia, which raised critical questions about how we can trust the silicon in our devices. The conversation explores the challenges of validating hardware components, the potential for backdoors in devices, and the implications of counterfeit components in the supply chain. The hosts share anecdotes and insights about their experiences with hardware security, emphasizing the need for independent testing and the importance of understanding the provenance of hardware components.
