The highly publicized computer hack of Target store credit card information was a loud wake up call. If we didn't already know that computers are vulnerable to hackers, we certainly do now.
So along comes these guys who have developed a little device that when installed in a vehicle can control the computers in that vehicle which control just about everything the vehicle can do. See Forbes.com -- This iPhone-Sized Device Can Hack A Car, Researchers Plan To Demonstrate. But their device has its limits:
For now, the tool communicates via only Bluetooth, limiting the range of any wireless attack to a few feet. But by the time the two researchers present their research in Singapore, they say they’ll upgrade it to use a GSM cellular radio instead that would make it possible to control the device from miles away.
Terrific. If these white hat hackers can develop such a system it's only a matter of time before the criminal hackers can do it.
