An information collection device including a processor and a communication unit that communicates with a control device installed at a vehicle. The processor is configured to send a message in a specific way to the control device that is in a test mode, receive from the control device a determination result about a state of the control device which has been determined based on the message sent in the specific way, send another message in a usual way to the control device in a case in which the determination result indicates that the state of the control device is normal, and receive, from the control device, anomaly information relating to communication in the control device, in response to the other message sent in the usual way.

Information collection device, information collection system, information collection method, and storage medium storing program

A determination device includes a processor. The processor being configured to: send first information that is not conforming to a rule of a firewall to a control device, execute first determination processing in which the control device is determined to be in a malfunction state in a case in which a first notification acquired from the control device is a normal notification, and the control device is determined to be in a normal state in a case in which the first notification is an abnormal notification, additionally send second information conforming to the rule to the control device in a case in which the control device has been determined to be in a normal state, and execute second determination processing in which the control device is determined to be in a normal state in a case in which a second notification acquired from the control device is the normal notification.

System for detecting control device security malfunctions

An information collection method includes determining whether or not a vehicle satisfies predetermined conditions when a target device receives a test mode start request from an collection device, and when it is determined that the vehicle satisfies the predetermined conditions, starting the test mode. In the test mode, update of a predetermined counter is stopped. The collection device generates a first MAC based on the count value received from the target device and transmits an attack information acquisition request with the first MAC to the target device. If the attack information acquisition request with the first MAC is received from the collection device, the target device generates a second MAC based on the stopped count value, determines that the host device is normal in a case where the first MAC and the second MAC coincide with each other, and transmits the attack information to the collection device.
