Hacking a Car remotely with $20 iPhone sized Device

Hacking Smart Car with CAN Hacking Tool kitIn the era of Smart devices, we have Smartphones, Smart TVs, Smart Fridges, and even the Smart cars! We have made our life very easy and comfortable by providing the master control of every task to such smart devices.
But imagine if an attacker wants to take revenge or hurt someone, now they can just hack cars, rather than failing their breaks in the traditional way. Sounds Horrible !
