Yep. Jeep Cherokee was hacked by connecting to multimedia system which supposed to be separate from driving system, yet our wasn&#x27;t a problem.<p>All they had to was reprogram one of controllers and full access was granted.<p>Even if you don&#x27;t reprogram controllers you don&#x27;t have guarantee that some components won&#x27;t go high wire when your modded version dies something different.<p>The best approach would be if manufacturers would provide an air gap, but they probably won&#x27;t, to save costs.
