The attack detection apparatus has a CAN (Controller Area Network) that transfers a signal to a plurality of nodes by a differential voltage between two signal lines, and a short circuit detector that monitors the signal transferred by the two signal lines of the CAN, and detects a short circuit between the two signal lines on the basis of a change in the signal indicating a characteristic of a short circuit attack by an unauthorized node.
