CAN Injection: Keyless car theft
CAN network by its nature is supposed to be a &quot;trusted network&quot; with no external Inputs available (Air Gapped).  But yeah, because headlights and blinkers needllessly complicated, cough er, need data uplinks.... totally NOT to check with Toyota if you&#x27;ve subscribed to their monthly &quot;safety package&quot; for $7.99, yeah, we&#x27;ve sort violated the Air Gap principal.<p>Here&#x27;s the problem everyone needs to pay attention to: If you demand Encrypted OR Signed CAN Bus, you will ABSOLUTELY get it from the manufacturers in the name of security. They will _gladly_ lock out the CAN bus so no third party accessories or diagnostic tools can work with your car.<p>So be careful what you scream for. We already have enough un-repairable items.
