The gadget that can hack any CAR

               Hackers could soon take control of your car - using a homemade gadget that is smaller than an mobile phone, Called the CAN Hacking Tool (CHT), the device can be fitted to any car's Controller Area Network 'within minutes' and run malicious code through the vehicle's system. 
Once hackers take hold of this network they can control lights, locks, steering and even brakes also.
HOW DOES THE CAN HACKING TOOL WORK:
        Many cars come with built-in software that run on an operating system in a similar way to phones and computers.
The CAN Hacking Tool (CHT) has four wires that are attached to the different outputs of a car's Controller Area Network.
A 60p ($1) computer chip is used to bypass any encryption on the car before reading and writing data from the flash memory of the vehicle's engine control unit. 
The gadget is smaller than an iPhone, meaning it sits in the palm of the hacker's hand, and can be controlled remotely. 
Hackers can use any command they want to program an action via the CHT, and this includes disabling the brakes, deploying the airbag, locking the doors and enabling the alarm.
