Explore the critical role of analog-to-digital converters (ADCs) in connecting the analog and digital worlds in this 51-minute Black Hat conference talk. Delve into the fundamentals of ADCs, their functionality, and importance in modern systems. Examine potential vulnerabilities in ADC interpretation and learn about techniques to manipulate ADC data. Gain insights into aliasing, filtering, and signal processing concepts. Witness practical demonstrations, including a Python simulation, showcasing how ADCs can be fooled. Analyze various ADC types, their susceptibilities, and potential causes for manipulation. Understand the implications of ADC vulnerabilities in embedded systems, industrial control systems, and everyday devices.
