US Patent 10193903 Systems and methods for detecting suspicious microcontroller messages

The disclosed computer-implemented method for detecting suspicious microcontroller messages may include (1) observing a typical interval at which messages are sent over a network by a microcontroller, (2) identifying a message sent over the network by the microcontroller, (3) determining that the interval between the message and the previous message sent by the microcontroller does not comprise the typical interval, and (4) categorizing the message as a suspicious message in response to determining that the interval does not comprise the typical interval. Various other methods, systems, and computer-readable media are also disclosed.
