Cars Being Stolen With Keyless Entry
Car owners who leave their keys on a table or near their front doors may be unwittingly allowing thieves to hijack the signal. This relay attack is one of the advanced methods criminals are employing to steal new keyless vehicles.
All keyless ignition cars emit an extremely low-power radio signal, seeking a compatible fob that can respond. If the signal can be captured and recreated, it can be used unlock the car, and also to start it.
Relay Attack
Imagine your car at your driveway, with your key fob in your home. You're confident that your car is safe, but not seen by you sophisticated thieves are planning an attack. Instead of slamming windows or jiggling locks, they are using technology to gain access to cars through digital chinks in their armor. Also known as relay theft, it's becoming a common method of stealing vehicles with keyless entry.
The keyless entry system in cars is controlled by a signal by the car's RF transmitter to the key fob. To prevent unauthorized keyless entry the RF transmitters on the key fob as well as in the car are programmed to activate only when they're within a specific distance from one another. However, thieves can circumvent this limitation employing a method known as the "relay-attack".
To accomplish this, two people work together: one stands by the car with the device that captures an electronic version of the key fob's signal. The other, who is at the home of the owner and using a second device to transmit the key fob signal back to the car. This trick tricked the car into thinking that the key fob is close enough to be able to unlock it and begin the engine.
In the past, this type of attack required expensive equipment to perform. You can now buy a cheap relay transmitter online and pull off an heist in just a few minutes. This is why it's well-liked by car thieves.
While certain vehicles are less vulnerable to this type of theft than others, all modern cars with keyless entry are at risk. In fact researchers have examined 237 popular vehicles and found that they could be targeted by this method.
Tesla vehicles are believed to be less vulnerable to this kind of theft. However Tesla hasn't yet implemented UWB technology that would enable it to perform distance checks and prevent relay attacks. The company has stated that they will make this happen in the near future, but until then they are still vulnerable. Installing an anti-theft device that guards your car and your keys against such attacks is a proactive method to ensure your car's security.
CAN Injection Attack
Modern cars can guard themselves against thieves by transferring encrypted messages using the key in order to confirm its authenticity. This method is generally thought to be secure, but thieves have found a way to circumvent it. They impersonate the smart key, then send messages to the vehicle and then drive off. To do this, they gain access to the smart keys' internal communication network.
Most cars today are equipped with between 20 and over 200 electronic control units, also known as ECUs, that manage various aspects of the vehicle's operation. They communicate using the CAN bus network. 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 by the ECU that controls the smart key or door. These messages aren't always encrypted or authenticated. This means that criminals are able to take them over with a simple and cheap device.
To accomplish this, they must look for a spot where they can directly connect to the CAN bus connector wires. They usually hide in the headlights or in other locations in the front of the vehicle. To get them, you can remove the bumper and cut holes in the headlamp assemblies. The thieves use an instrument known as an CAN injection attack to send fake messages which fool the safety systems of the car to unlock and disable the engine immobilizer.
The devices are available through 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 discovered the CAN Injection attack recommend that all car makers fix this in their existing models. However, these thieves will continue taking any opportunity they can. The best we can do is attempt to stop this from happening by putting in mechanical security measures such as Discloks on all of cars and ensuring that they are always parked in well-lit areas that are easily visible to pedestrians.
Jamming the Signal
In a different variation of the relay attack, thieves can make use of a device to block the signal sent from a key fob when the car is locked. The device could be found inside the pocket of a thief in a parking space or in a hideout near the driveway that is being targeted. Once owners press the button to lock their fobs, and then walk away and leave, they don't have to think about whether or not the car is really is locked. The device of the crook blocks the signal that locks the vehicle. Therefore, thieves can escape with the car.
The crooks also employ devices to amplify the key fob's signals in order to unlock vehicles. They may even accomplish this if the key is inside the pocket of the driver or hanging from a hook in the house. Once the car has been unlocked, hackers can make use of a standard diagnosis port to create the fob with a blank.
To protect against this type of attack, car manufacturers have come up with a range of anti-theft devices. But thieves always come up with new ways to beat these measures.
They've started using devices that transmit at the same frequency as remote keyfobs to intercept signals. The crooks can then copy the key fob's unlock code and start the car with this fake signal.
This method is particularly popular in the US and Europe where a lot of automobiles are sold with wireless technology that lets owners unlock and start their vehicle using a mobile app from their phones. This technology is expected to become increasingly popular as website more and more car manufacturers attempt to connect their vehicles with their owner's smartphones.
It is crucial that drivers follow the best practices when parking their vehicles. They should never leave their keys in the ignition, and should always ensure that their car is securely locked when they're not in it and should make use of the steering wheel or a gearstick lock if possible. They should also consider installing a tracking device on their vehicle in the event that it is stolen.
Flat Battery
This kind of attack is more frequent than many people believe. Thieves use cheap devices to extend the signal from your key fob to unlock and start a car even when it's turned off. They then drive the car around the corner or even to a trailer and take off with it. It would be possible to protect your car from this by installing an interrupter switch for the starter circuit. Simpler versions have an ON/OFF button which interrupts the circuit. It's about $15 and is simple to install.
Car thieves are always looking for new ways to gain access to vehicles and take them away. The police as well as the car makers and insurance companies are always trying to catch up to their tactics and provide better anti-theft systems for modern vehicles. But that doesn't stop the thieves who are able to be quick to adapt and discover ways to bypass the latest anti-theft measures.
Many thieves jam the signal with devices that use the same radio frequency of the fob. They put the device in their pockets or in a location close to their vehicle, and it stops the fob's lock command from reaching the vehicle, leaving it unlocked. This can be done within minutes. The device is cheap and is available online.
Another strategy is to hack into the car's computer system. This is more difficult, but still possible. Hackers have created devices that connect to the diagnostic port of all cars and allow them to access the software. From there, they are able to program a blank key fob and make it work. It is possible to do this on older cars as well but it's more difficult without removing the ignition.
This method is likely to become more popular if more vehicles are connected to drivers' phones. Once a thief gets the username and password for the vehicle app and then they can unlock the car or start it with the app on their phone. You can guard yourself by not putting valuables in your car and parking in a garage.
