    With car theft on the rise around my parts, I'm wondering if my 2017 Prius Two is susceptible to the CAN Bus injection attack that thieves have been using. I'm guessing my car isn't fancy enough to have that vulnerability, but I just wanted to be sure.

    Does anyone have an authoritative source that can show me if my model uses this technology?

    If you're not familiar, this is a 1 min video that shows what the CAN Bus injection attack looks like:


    Related: I recently learned how to disable the remote to prevent relay or repeater type attacks:
    Disabling the key fob's wireless signal:
    1. Press and hold the lock button on the key fob.
    2. While holding the lock button, press the unlock button twice.
    3. The LED on the key fob will flash four times to indicate it's been switched off.
    4. To re-enable the key fob, simply press any of the buttons.

    But who really wants to steal a Prius?
