A system and method for intrusion detection on automotive controller area networks. The system and method can detect various CAN attacks, such as attacks that cause unintended acceleration, deactivation of vehicle's brakes, or steering the vehicle. The system and method detects changes in nuanced correlations of CAN timeseries signals and how they cluster together. The system reverse engineers CAN signals and detect masquerade attacks by analyzing timeseries extracted from raw CAN frames. Specifically, anomalies in the CAN data can be detected by computing timeseries clustering similarity using hierarchical clustering on the vehicle's CAN signals and comparing the clustering similarity across CAN captures with and without attacks.
