Cars Being Stolen With Keyless Entry
If car owners leave their keys on the table or next to their doors, they may unknowingly be allowing thieves to hijack their signal. This relay attack is a high-tech method used by criminals to steal new keyless vehicles.
All keyless ignition cars emit an extremely low-power radio signal, looking for a matching fob to respond. If the signal can be recorded and recreated, it could be used to unlock the car, and also to start it.
Relay Attack
Imagine your car being parked safely in your driveway, with the key fob safely in your home. You might think that your car is safe but sophisticated thieves are planning a heist without you knowing. They use technology to snoop on vehicles through digital chinks. Also known as relay theft, it's becoming a common method of stealing vehicles with keyless entry.
The keyless entry system that is found in cars is controlled by a signal from the car's RF transmitter to the key fob. To ensure that keyless entry is not accessed by unauthorised persons the RF transmitters on the key fob as well as the car are programmed to turn on when they are within a certain distance of each other. However, thieves can override this restriction using a technique called the 'relay attack'.
Two people are required to do this: one person is close to the car and utilizes a device to capture a digitalized version of the the key fob. The other person, who is at the home of the owner is using a second device to transmit the signal from the key fob back to the car. This trick tricked the car into thinking the key fob is near enough to allow it to unlock and start the engine.
This type of attack was once a costly process that required expensive equipment. You can now buy an inexpensive relay transmitter online and pull off an heist in a matter of minutes. This is the reason car thieves are enthralled by it.
While certain vehicles are less vulnerable to this kind of theft than others, all cars with keyless entry are vulnerable. Researchers have examined 237 well-known cars and found that all of them are susceptible to being stolen using this method.
Tesla vehicles are believed to be less susceptible to this kind of theft. However Tesla hasn't yet implemented UWB technology that would allow it to conduct distance checks and stop attacks via relay. The company has promised to implement this feature in the near future, but until then, they remain vulnerable. Installing an anti-theft system that protects both your car and your keys against these types of attacks is a proactive approach to ensure your car's security.
CAN Injection Attack
Modern vehicles can defend themselves against thieves by exchanging encrypted messages with the key to confirm its authenticity. This system is generally reckoned to be secure, but criminals have found a way to circumvent it. They simply impersonate the smart key, and send messages to the car letting it unlock the doors, turn off its engine immobilizer, and then go on their way. To do that they have access to the smart key's internal communications network.
Today, most cars are fitted with between 20 and 200 electronic control units (or ECUs) that control various aspects of the car's operation. They communicate via the CAN bus network. These ECUs enter a low-power sleep mode to reduce their power consumption. This mode is activated when ECUs receive an "wake up" frame. These frames are usually sent by the ECU that is in charge of the smart key or door. These messages are not always encrypted or authenticated. This means that thieves can take them over with a simple and cheap device.
To accomplish this, they search for a spot where they can connect directly to the CAN bus wires. They usually hide in the headlights or in other locations in the front of the vehicle. To get them, you need to remove the bumper and make holes in the headlamp assemblies. The thieves then use a device called an CAN injection attacker to send out fake messages that trick the car's security systems into unlocking the car and disengaging its engine immobilizer.
These devices are available for sale on the Dark Web, and work for all major car makers, including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and more. The researchers who discovered this CAN Injection attack are recommending that all car makers address it in their existing models, but the reality is that these thieves will continue to take whatever they can get their hands on. The best we can do is to attempt to stop this from happening by putting in mechanical security measures like Discloks on our vehicles and ensuring that they are parked in well-lit areas that are easily visible to pedestrians.
Blocking the Signal
In a different variation of the relay attack, thieves could use a gadget to jam the signal that is sent by a key fob when the car is locked. The device could be found in the pocket or hidden place of a thief on a parking lot, or near the driveway being targeted. Owners aren't able to verify whether their vehicle is locked when they press the lock button. The device used by the criminal interferes with the signal to lock the car. Therefore, thieves could drive away with the vehicle.
The crooks also use devices to amplify the key fob's signals to unlock vehicles. The crooks are able to do this even when the key is in a pocket of a driver, or hanging from a hook inside the home. When the car is locked, they can use the standard diagnostic port or computer hackers to program an unlocked key fob to gain control of the vehicle.
To guard against this kind of attack, car manufacturers have developed a variety of anti-theft devices. However, thieves are always looking for ways to defeat these measures.
For instance, they've been using devices that transmit on the same radio frequency as remote key fobs to intercept their signals. The crooks then copy the unlock code of the key fob and begin the vehicle using this fake signal.
This method is very popular in the US and Europe where many vehicles are sold with wireless technology that lets owners unlock and start their cars using a mobile app on their phone. This technology is likely to be more commonplace as more companies attempt to connect their cars to their owners smartphones.
It is essential that drivers follow the right procedures to park their vehicles. They should never leave the key fobs in ignition and should always secure the car when not in it. If they can, they should also use a steering or gearstick locking device. They should also consider installing a tracking device onto their vehicle in case it is stolen.
Flat Battery
This kind of attack is more prevalent than many people believe. Thieves make use of inexpensive devices to extend the signal from your key fob to unlock and start the car, even if it's switched off. Then they drive the vehicle to the trailer or around a corner, and take the vehicle away. Installing a starter circuit interruption switch would protect your car against this. Simpler versions have an ON/OFF button that shuts off the circuit. It costs about $15 and is simple enough to install yourself.
Car thieves are always looking for new ways to enter vehicles and take them away. The police as well as the car makers and insurance companies are constantly trying to keep up with their tactics and develop better anti-theft systems for modern cars. But that doesn't stop thieves who are able change quickly and find ways to circumvent the most recent anti-theft measures.
Many thieves jam the signal with a device that uses the same radio frequency as the fob. They place the device in their pocket or somewhere close to their vehicle, and it blocks the fob's lock command from reaching the vehicle which leaves it unlocked. This can be accomplished in a matter of minutes. The device is inexpensive and is available on the internet.
Hacking the computer system of the car is an alternative option. This is more difficult but nevertheless feasible. Every car stolen keyless entry car has a diagnostic port, and hackers have designed devices that plug into them and let them access the software in the car. They can then program the fob with blank code to work. This can also be done on older vehicles, but it is more difficult without taking off the ignition lock.
As more vehicles are linked to drivers' phones and this method could become more popular too. Once a criminal has the username and password to the vehicle app they are able to unlock the car or start it with the app on their phone. You can guard yourself by not leaving valuables in your car and also by parking in garages.
