Explore the decade-long investigation into diesel emission cheating through this comprehensive technical conference talk from the 39th Chaos Communication Congress. Delve into the methodologies used to reverse-engineer dozens of engine ECU software systems and discover how researchers identified "defeat devices" that manipulated emission controls. Learn about the evolution from the initial 2015 Volkswagen scandal to the broader industry-wide diesel emissions fraud, examining various implementation techniques of defeat devices and their environmental impact. Understand the challenges of analyzing seemingly impenetrable automotive software systems and documenting findings for legal proceedings. Gain insights into the "Acoustic Function" defeat device and other sophisticated cheating mechanisms discovered through years of forensic software analysis. Discover how independent researchers can effectively analyze highly dynamic automotive systems that manufacturers design as black boxes, and explore the intersection of technical investigation, mechanical engineering, and legal expert testimony in exposing corporate fraud.
