CAN (Controller Area Network) BUS is not a new network, but unlike more popular network names, CAN BUS is geared more for Embedded Controllers such as the ones found in modern automobile. So when I speak of CAN BUS ‘Hacking’, I am refering to automotive network reverse engineering.
The CAN BUS is now a required network on vehicles manufactured in the U.S. from 2008 and beyond. It’s popularity amoung automotive OEMs is nearly universal. But unlike most open protocols such as TCP/IP and HTTP, CAN BUS is almost entirely implemented as a proprietary protocol. Thus if we want to understand it, we must ‘hack’ it.
I will be posting more about what exactly the CAN BUS is, but you can get more infomation on it from Wikipedia by clicking here.
