The controller space community, or CAN, is “a function of recent automobiles which permits totally different parts and methods to speak, (and) has just lately been focused and exploited by thieves,” stated Thatcham’s Launchbury.

The community permits sensors and management modules to speak to one another immediately, as an alternative of going by means of a central node. Thieves take benefit by accessing the community from the automobile’s exterior, normally by eradicating a headlight and connecting a tool that may “inject” a sign, tricking the automobile into unlocking and beginning.

Whereas automakers work on bettering CAN safety, “there are steps drivers can take in the present day so as to add layers of safety and deter criminals,” equivalent to utilizing a bodily lock, Launchbury stated.

Aftermarket digital immobilizer methods “ought to render a prison’s theft software ineffective,” and would possibly even get you a low cost on auto insurance coverage, he stated. Thatcham and different corporations supply them however the draw back is they are often fairly expensive.
