Never Trust Your Inputs - Causing Catastrophic Physical Consequences From The Sensor
Explore the critical security vulnerabilities in analog-to-digital converters (ADCs) used in Industrial Control Systems (ICS) and embedded systems. Delve into the rarely-addressed topic of analog signal processing security, examining how attackers can manipulate frequency, phase, and signal ranges to cause ADCs to output spurious digital signals. Analyze various attack vectors on ADCs, misconfiguration of signal scaling, and design flaws that allow attackers to deceive ADCs and dependent systems. Learn how these vulnerabilities can be exploited in software through demonstrations, and understand the potential catastrophic physical consequences of such attacks in the context of industrial processes. Gain essential knowledge on understanding data sources and pathways to maintain efficiency and safety in ICS environments.
