Daniel Lange and Felix "tmbinc" Domke bought some of Volkswagen's cheating Engine Control Units on Ebay and extracted and decompiled the software in them to learn exactly how the cheating took place.
Their presentation at the thirty-second Chaos Communications Congress presents their findings, which include a detailed analysis of the software trickery used to detect when the car was being tested by a regulator to change the car's emissions characteristics.
They also reveal that they've discovered other cars that use VW's techniques to cheat on tests.
