Hand-Sized Device Can Hack Cars Remotely, Researchers Call for Greater Security

The device will be presented at the Black Hat Asia security conference in Singapore next month
A team of Spanish security researchers is out to
beef up auto security
by showing its ability to hack a car with a device the size of your hand.
, security researchers Javier Vazquez-Vidal and Alberto Garcia Illera plan to show a new device they've built at the Black Hat Asia security conference in Singapore next month -- and they're hoping it will be a wake-up call for the auto industry.
The device is called the CAN Hacking Tool (CHT) and it attaches via four wires to the Controller Area Network or CAN bus of a vehicle. It draws power from the car’s electrical system and allows an attacker to send wireless commands remotely from a computer.
The researchers say it's as easy as lifting the hood real quick or simply sliding under the car to attach the device to a vehicle and walk away.
From there, the attacker could switch off headlights, set off alarms, roll windows up and down, and access anti-lock brakes or emergency brakes. The researchers have already tested it on four different vehicles, although they won't reveal which makes and models.

For right now, the device only works using Bluetooth, which means it can be controlled from just a few feet away. But the research team said that by the time the conference rolls around next year, it will implement a GSM cellular radio, which will allow remote control of the vehicle from a few miles away.
“It can take five minutes or less to hook it up and then walk away,” said Vazquez-Vidal. “We could wait one minute or one year, and then trigger it to do whatever we have programmed it to do.”
What makes matters worse is that the items needed to build the device can all easily be bought from store shelves, and costs under $20 total.
Also, it's nearly impossible to trace the attacker, according to the researchers.
The team said they built the device to show automakers what attackers are capable of, and to call for greater security in cars, which are becoming increasingly connected and more vulnerable to hacks.
“The goal isn’t to release our hacking tool to the public and say ‘take this and start hacking cars,’” says Vazquez-Vidal. “We want to reach the manufacturers and show them what can be done.”

This is a non-issue

First of all, all of these issues are address in OBDIII.
1) OBDIII tells you when a 3rd party device is plugged into the PEG port or is running on the CAN BUS.
2) OBDIII sets off the alarm/immobilizes the vehicle is the alarm system is active when a device is plugged in.
3) OBDIII divides up the emissions, restraint, braking, engine control, climate control, steering/suspension and entertainment systems of a vehicle into separate groups. All groups except or emissions are vendor-specific.
3a) Unfortunately this means that proprietary readers will be required for each brand of vehicle to identify problems other than emissions.
3b) Fortunately, this means that no universal devices will be able to compromise a vehicle, unless they want to hack that EGR reading from 2 miles away.
In the near term, its important to consider how ineffective this device will be on OBDII vehicles:
1) I doubt it can take control of a moving vehicle since most vehicles don't allow parameter modification to safety systems when the VSS reads a speed above zero. All vehicles require a restart for RSM/ABS modules to initialize newly written data.
2) If you are in a stationary vehicle and somebody takes control of it by moving it, you can
a) remove the keys/hold the start button for 5 seconds
b) apply the brake pedal. this is a mechanical system that can not be disabled/overridden.
I am absolutely dying to see this thing work. It may take advantage of one model vehicles' flaws, or at best one manufactures flaws, but to make a device that can "take control" of all vehicles using the CAN BUS is impossible.
I hope they call it Series T-X
