Cars Being Stolen With Keyless Entry
Car owners who leave their keys on tables or near their front doors could be giving thieves the ability to take over the signal. This relay attack is a highly-tech method criminals use to steal keys from new vehicles.
Keyless ignition vehicles emit a low power radio signal to locate an appropriate fob. If the signal is captured and recreated, it could be used to unlock the car and start it.
Relay Attack
Imagine your car being parked safely in the driveway, and the key fob tucked away inside your home. You may think your vehicle is secure, but sophisticated thieves are planning to steal your car without you being aware. The thieves employ technology to hack into vehicles using digital chinks. This method of stealing cars with keyless access is called relay theft.
The keyless entry system that is found in cars is controlled by a signal by the car's radio transmitter to the key fob. To ensure that keyless entry is not accessed by unauthorized individuals the RF transmitters that are on the key fob and the car are programmed only to be activated when they are within a certain distance from each other. The thief is able to circumvent this restriction employing a technique called the relay-attack.
To accomplish this two people work in tandem: one stands by the car and uses an instrument that records a digitized version of the key fob's signal. The other, standing by the owner's house is using a different device to transmit the key fob's signal down to the car. This trick tricks the car into believing that the key fob has reached the distance needed to unlock and start the vehicle.
This type of heist was once a costly process that required expensive equipment. Today, you can purchase a cheap relay transmitter online and pull off an heist in a matter of minutes. This is the reason car thieves are enthralled by it.
All modern cars with keys are at risk. Certain vehicles are more vulnerable to this type than others. Researchers have examined 237 well-known cars and found that every one of them can be stolen using this method.
Tesla vehicles are believed to be less prone to this kind of theft. However Tesla hasn't yet implemented UWB technology that would allow it to perform distance checks and stop attacks via relay. The company has stated that they'll implement this in the near future, but until then, they are vulnerable. Installing an anti-theft device that guards your car keys and your keys against such attacks is a proactive way to ensure the security of your car.
CAN Injection Attack
Modern cars are designed to guard themselves from theft by exchanging cryptographic messages with the key to prove it's genuine. The system is considered to be safe, but thieves have found ways to get around it. They fake the identity of a smart key, send messages to the vehicle and then drive off. To do this, they gain access to the smart keys' internal communications network.
Nowadays, the majority of cars are equipped with between 20 to 200 electronic control units (or ECUs) that manage different aspects of the car's operation. They communicate through an electronic network known as CAN bus. 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 manages the smart key or door. These messages aren't always authenticated or encrypted. This means that criminals can take them over with an inexpensive and simple device.
To do this, they look for a place where they can connect directly to the CAN bus connection 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 make holes in the headlamp assemblies. The criminals then employ a device dubbed an CAN injection attacker to send fake messages that trick the car's security systems into unlocking it and disengaging its engine immobilizer.
These devices are available for sale on the Dark Web, and work for the majority of major car manufacturers which include BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and many more. Researchers who have discovered the CAN Injection attack recommend that all car makers address this in their existing models. However, these thieves will continue taking here everything they can. The best thing we can do is to attempt to stop this from happening by installing security measures that are mechanical like Discloks on our vehicles, and making sure that they are parked in well-lit areas that are easily visible to pedestrians.
Blocking the Signal
In a variant of the relay attack, which employs a device that is able to block the signal transmitted by a key fob while the vehicle is locked. The device could be found hidden in the pocket of a burglar in a parking space or in a hideout close to the driveway that is being targeted. The owners don't know if the car is locked after pressing the lock button. Instead, thieves are able to drive off with the vehicle because the signal that normally locks the car is blocked by the crook's device.
They also have devices that amplify signals from the key fob to unlock vehicles. The crooks can do this even when the key is in a pocket of a driver, or hanging from a hook inside the home. After the car is unlocked, hackers can make use of the standard diagnostic port to create the fob with a blank.
Automobile manufacturers have developed a variety of anti-theft solutions to guard against these kinds of attacks. But, thieves are constantly finding ways to beat these measures.
For example, they've started using devices that transmit on the same frequency as remote key fobs in order to intercept their signals. The thieves copy the unlock code from the key fob, and then start the vehicle with this fake signal.
This technique is particularly popular in the US, where many cars have wireless technology. Owners can unlock and start their vehicle using a mobile application on their smartphone. This technique is likely to be more commonplace as more car manufacturers attempt to connect their cars to their owners smartphones.
It is crucial that drivers use best practices to park their vehicles. They shouldn't leave their key fobs in the ignition, should always make sure the car is fully locked when they're not using it and should make use of a steering wheel or gearstick lock if possible. They should also think about installing a tracking device to their vehicle in the event that it is stolen.
Flat Battery
This kind of attack is more frequent than people think. Thieves use cheap devices to extend the signal from your key fob to unlock and start the car, even if it's shut off. Then, they drive the car to the trailer or around a corner to take the vehicle away. It is possible to protect your car from this by installing a starter circuit interrupt switch. Simpler versions have an ON/OFF button that interrupts the circuit. It's about $15 and is simple enough to install yourself.
Car thieves are constantly seeking new ways to rob vehicles. Car manufacturers, police and insurance companies are always trying to keep up with the latest methods and offer better anti theft systems for modern vehicles. However, this does not stop thieves who are able to be quick to adapt and find ways to bypass the most recent anti-theft measures.
For instance, a lot of thieves use devices that operate on the same frequency as the fob in order to block the signal. They place the device in their pockets or somewhere close to their vehicle, and it blocks the fob's lock commands from reaching the car, leaving the vehicle unlocked. This can be accomplished in a matter of seconds. The device is affordable and readily available on the internet.
Another strategy is to hack into the car's computer system. This is harder but still feasible. Every car has an diagnostic port and hackers have created devices that plug into them and let them access the car's software. From there, they can program the blank key fob to get it to work. This can also be done on older vehicles, however it is more difficult to do so without taking off the ignition lock.
This method could become more popular as more vehicles are connected to drivers' phones. Once a burglar has gained the username and password to a vehicle app they are able to open the car or get it started using the app on their phone. You can protect yourself by not putting valuables in your car and by parking in a garage.
