Abstract: A vehicular electronic device hacking test apparatus includes a transmitter, a receiver, and a processor configured to classify a communication-connection procedure into a plurality of states based on a preset communication protocol, to generate a mutated packet appropriate for the plurality of states, and to transmit a vehicular electronic device through the transmitter, and to determine whether the vehicular electronic device is vulnerable to hacking based on whether a reception packet corresponding to the mutated packet is received through the receiver.
