Abstract
The disclosed computer-implemented method for detecting anomalous messages in automobile networks may include (1) receiving automobile-network messages that are expected to be broadcast over an automobile network of an automobile, (2) extracting a set of features from the automobile-network messages, and (3) using the set of features to create a model that is capable of distinguishing expected automobile-network messages from anomalous automobile-network messages. The disclosed computer-implemented method may further include (1) detecting an automobile-network message that has been broadcast over the automobile network, (2) using the model to determine that the automobile-network message is anomalous, and (3) performing a security action in response to determining that the automobile-network message is anomalous. Various other methods, systems, and computer-readable media are also disclosed.
