Abstract
The disclosed computer-implemented method for identifying suspicious controller area network messages may include (i) monitoring, for a predetermined period of time, messages sent by an electronic control unit that comprise a controller area network identifier for at least one controller area network device, (ii) observing, in the messages, a set of corresponding patterns that each comprise a content pattern and a timing pattern, (v) detecting a message that comprises the controller area network identifier, wherein a content pattern of the message and a timing pattern of the message do not match any pair of corresponding patterns in the set of corresponding patterns, and (vi) determining that the message is suspicious based at least in part on content pattern of the message and the timing pattern of the message not matching any pair of corresponding patterns in the set. Various other methods, systems, and computer-readable media are also disclosed.
