Cars Being Stolen With Keyless Entry
Car owners who leave their keys on a table or in front of their front door could be giving thieves the ability to take over the signal. This relay attack is just one of the high-tech methods criminals are employing to steal new keys from cars.
All keyless ignition vehicles emit a low-power radio signal to locate the fob that matches. If the signal is captured and recreated, it could be used to unlock the car and start it.
Relay Attack
Imagine your car safely in your driveway, and your key fob at home. You're confident that your vehicle is secure, but unseen by you sophisticated thieves are planning a heist. The thieves employ technology to snoop on vehicles through digital chinks. Also known as relay theft, it's an increasingly common way to steal cars with keyless entry.
The keyless entry system in cars is controlled by a signal sent by the car's radio transmitter to the key fob. To stop keyless entry by intruders the RF transmitters on the key fob and the car are programmed to activate when they are within a certain distance of each other. However, thieves can circumvent this limitation using a technique known as the relay-attack.
Two individuals are required to perform this: one stands near the car and uses a device to capture digitally the the key fob. The other, in the vicinity of the owner's house is using a different device to transmit the key fob signal back to the car. This trick tricks the car into thinking the key fob is near enough to be able to unlock it and start it up.
This type of attack used to require expensive equipment. It is now possible to purchase an inexpensive relay transmitter online and carry out a heist within minutes. This is the reason why car thieves love it.
While certain vehicles are less prone to this kind of theft than others, all modern vehicles with keyless entry are vulnerable. In fact researchers have tested 237 vehicles that are popular and found that they could be all stolen using this method.
Tesla vehicles are said to be less prone to this kind of theft. However Tesla hasn't yet implemented UWB technology to enable it to perform distance checks and stop relay attacks. The company has said that they'll implement this in the near future, but until then, they are vulnerable. Installing an anti-theft device that safeguards your keys and your car against such a threat is a proactive way to ensure the security of your vehicle.
CAN Injection Attack
Modern vehicles can defend themselves against thieves by transferring encrypted messages using the key to prove its authenticity. The system is considered to be secure, however thieves have found ways around it. They fake the identity of a smart key, transmit messages to the vehicle and then drive off. To do this, they gain access to the smart keys' internal communication network.
Today, most cars are equipped with between 20 to 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate with one another using the CAN bus. These ECUs are put into a low power sleep mode to lower their power consumption. This mode is activated when the ECUs receive a "wake up" frame. These frames are usually sent through the door or a smart key receiver ECU. These messages aren't always encrypted or authenticated. This means that criminals can intercept them with a simple and cheap device.
To accomplish this, they must look for a place where they can connect directly to the CAN bus connector wires. They are usually hidden in the headlights or in front of the vehicle, and are accessible by pulling the bumper and cutting holes in the headlamp assembly to expose the wires. The thieves then use a device called an CAN injection attacker to send fake messages which trick the car's security systems to unlock it and disable the engine immobilizer.
The devices are available on the Dark Web and work with most major car manufacturers including BMW and Cadillac, Chrysler, Fiat and Ford, Honda, Hyundai and Jeep, Lexus and Nissan, Renault and Toyota, Volkswagen and Maserati. Researchers who have discovered the CAN Injection attack recommend that all car manufacturers fix this issue in their existing models. However, these thieves will continue to take whatever they can. The best we can do is to try and prevent this by putting in mechanical security measures like Discloks on all our vehicles and ensuring that they're always parked in well-lit areas that are easily visible to pedestrians.
The Signal is blocked
In a variation of the relay attack that makes use of a device, thieves can jam the signal transmitted by a key fob while the car is locked. The device may be in the pocket of a thief in a parking space or in a hidden spot near the driveway being targeted. Once the owners press the lock button on their fobs, and then walk away, they don't think about whether or not their car is really locked. Instead, thieves could escape with the vehicle because the signal that normally locks the car has been blocked by the device of the criminal.
The crooks also employ devices to amplify the signal from the key fob to unlock vehicles. The crooks can accomplish this even if the key is in a pocket of a driver, or hanging from an outside hook in the home. When the car is unlocked, they can make use of an ordinary diagnostic port or computer hacker to program the blank key fob and gain control over the vehicle.
To protect against this type of attack, car makers have developed a variety of anti-theft gadgets. But, thieves are constantly trying to beat these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs to intercept signals. The thieves then copy the unlock code from the key fob and begin the vehicle using this fake signal.
This method is especially popular in the US where a lot of cars are equipped with wireless technology. Owners can unlock and start their vehicle through a mobile application on their smartphone. This technology will likely become more popular as more car manufacturers attempt to connect their vehicles with their owners phones.
In addition to implementing anti-theft systems in vehicles, it's vital for drivers to use the best practices when parking their vehicles. They should never leave their key fobs in the ignition. They should always ensure that their vehicle is locked completely when they're not in it and should use an engine or steering wheel lock, if they can. They should also consider having a tracking device fitted to their vehicle in the event that it is stolen.
Flat Battery
This kind of attack is more frequent than people think. Thieves make use of cheap devices to extend the signal from your key fob to open and start a car even when it's shut off. They then simply drive the car around a corner or even to a trailer and take off with it. Installing an interrupter switch for the starter circuit can protect your vehicle from this. The most basic ones have an ON/OFF switch that shuts off the starter circuit. It's about $15 and is easy to install.
Car thieves are always trying new ways to get into vehicles and then steal them. Car manufacturers, police and insurance companies are always trying to keep up with the latest tactics and provide more effective anti-theft systems for modern vehicles. But this isn't stopping thieves who easily adapt and find ways to circumvent the latest anti theft measures.
A lot of thieves block the signal by using more info devices that use the same radio frequency as the fob. They put the device in their pockets or in a location near their vehicle, and it blocks the fob's lock commands from reaching the vehicle which leaves the vehicle unlocked. This can be done in a matter of seconds. The device is cheap and easily accessible on the internet.
Hacking the computer system of the car is another option. This is more difficult, but it is still feasible. Hackers have designed devices that connect to the diagnostic port of all vehicles and allow them to connect to the software. From there, they can program an unfinished key fob and make it work. It is also possible to do this on older vehicles, but it is more difficult to do without taking off the ignition lock.
This method could become more popular if more vehicles are connected with drivers' mobile phones. Once a criminal has the username and password to the vehicle app they are able to unlock or start the car with the app on their phone. You can guard yourself by not putting valuables inside your car, and by parking in garages.
