Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or at their doors, they may unknowingly be allowing thieves to steal their signal. This relay attack is one of the advanced methods criminals are employing to steal new keyless vehicles.
Keyless ignition vehicles emit a low-power radio signal that is used to locate an appropriate fob. If the signal is recorded and recreated, it can be used to unlock the car and then start it up.
Relay Attack
Imagine your car parked in your driveway with your key fob in your home. You may be confident that your car is secure however, sophisticated thieves are planning to steal your car without you even knowing. Instead of breaking windows or jimmying locks, these thieves are leveraging technology to hack into vehicles using digital chinks in their armor. Also known as relay theft, it's becoming a common way to steal cars that have keyless entry.
Keyless entry cars are designed to operate using a signal transmitted from the remote control (RF) transmitter to the owner's key fob. To stop keyless entry by unauthorised persons, the RF transmitters on the key fob and the car are programmed only to turn on when they are within a certain distance from one another. A thief, however, is able to circumvent this restriction employing a method known as the relay-attack.
To do so two people work in tandem one is positioned by the car, using a device that captures digitally the key fob's signal. The other, who is at the home of the owner is using a different device to send the key fob's signal to the car. This trick tricks the car into believing the key fob has traveled a distance sufficient to allow it to be opened and started the vehicle.
In the past, this kind of attack required expensive equipment to perform. However, now you can pick up relay transmitters on the cheap online and execute a heist in minutes. This is the reason car thieves love it.
All modern vehicles that have keyless access are at risk. Some cars are more vulnerable to this type of attack than others. In fact, researchers have tested 237 popular vehicles and found that they could all be stolen using this method.
Tesla vehicles are believed to be less susceptible to this type of theft, however Tesla hasn't yet implemented UWB features to effectively check distances on the car's signal to stop relay attacks. The company has promised to make this happen in the near future, but until then they are still vulnerable. That is why it's important to be proactive about your security in your car and install an anti-theft device which protects your keys as well as your car from these types of attacks.
CAN Injection Attack
Modern cars can guard themselves from theft by sending encrypted messages to the key in order to confirm its authenticity. This method is generally thought to be secure, however thieves have found a way around it. They can pretend to be the smart key and send messages to the vehicle letting it unlock the doors, turn off its engine immobilizer, then let them leave the car. To do this, they get access to the smart key's internal communication network.
Nowadays, the majority of cars are equipped with between 20 to 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate through the CAN bus network. These ECUs enter a low-power sleep mode to reduce their power consumption. This mode is activated when the ECUs receive a "wake up" frame. These frames are typically sent by the ECU that controls the smart key or door. These messages aren't always encrypted or authenticated. This means that criminals can capture them using an inexpensive and simple device.
They look for a place where they can connect here directly to the wires for CAN connection. They are usually hidden within the headlights or in front of the car, and are accessible by removing the bumper and cutting holes in the headlamp assembly to expose them. The criminals then employ a device dubbed a CAN injection attacker to send fake messages which trick the car's security systems into unlocking it and disengaging its engine immobilizer.
These devices are for sale on the Dark Web, and work for all major car manufacturers including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and many more. The researchers who discovered this CAN Injection attack are recommending that all car makers fix it in their existing models, but the reality is that these thieves will continue to grab everything they can lay their hands on. We can stop this by implementing mechanical safety measures such as Discloks in all of our cars and parking them in well-lit and visible areas.
Blocking the Signal
In a different variant of the relay attack, thieves could make use of a device to block the signal that is sent by an electronic key fob if the car is locked. The device could be inside the pocket of a burglar in a parking space or in a hideout near the driveway being targeted. Once owners press the lock button on their fobs and leave, they don't think about whether or not the car is really locked. Instead, thieves can drive off with the vehicle since 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 accomplish this even if the key is inside a pocket of a driver, or hanging from an outside hook in the home. Once the car is unlocked, they can make use of the standard computer hacker to program the blank key fob and gain control over the vehicle.
To protect against this type of attack, car manufacturers have developed a variety of anti-theft devices. But thieves always find ways to defeat these measures.
For instance, they've been using devices that transmit on the same frequency as remote key fobs to intercept their signals. The crooks can then copy the key fob's unlock code and then start the car using this fake signal.
This technique is especially popular in the US and Europe where a lot of vehicles are sold with wireless technology that allows owners to unlock and start their vehicles by using a mobile application from their phones. This technology is expected to become more popular as more and more car manufacturers try to connect their vehicles with their owner's smartphones.
It is crucial that drivers use best practices to park their vehicles. It is not a good idea to leave keys in the ignition. They should always ensure that the car is securely locked when they're not in it and should use the steering wheel or a gearstick lock if possible. It is also recommended to consider installing a tracking device to their car in the event it gets stolen.
Flat Battery
This type of attack occurs more often than people realize. The thieves use low-cost devices that increase the signal from your key fob to unlock and start your car, even in the event that it is off. They then drive the car around a corner or even to a trailer and then drive off with it. It is possible to protect your vehicle from this by installing an interrupter for the starter circuit. Simpler versions have an ON/OFF button which interrupts the circuit. It costs about $15 and is simple enough to install by yourself.
Car thieves are always looking for new ways to rob vehicles. Police, car manufacturers and insurance companies are always trying to keep up with the latest methods and offer better anti-theft systems for modern vehicles. However, that doesn't stop thieves, who are able to be quick to adapt and find ways to get around the most up-to-date anti-theft systems.
A lot of thieves block the signal using devices that use the same radio frequency as the fob. They place the device in their pocket or near their vehicle, and it blocks the fob's lock commands from reaching the vehicle which leaves it unlocked. This can be done in a matter of seconds. The device is cheap and can be purchased online.
Another strategy is to hack into the car's computer system. This is more difficult, but it is still possible. Every car has an diagnostic port and hackers have designed devices that plug into them and allow them access the software of the car. From there, they can program a blank key fob and get it to work. It is also possible to do this on older vehicles, however it is more difficult without removing the ignition lock.
This method could become more popular if more vehicles are connected with drivers' phones. Once a burglar has the username and password to a vehicle app and is able to unlock or start the vehicle using the application. You can safeguard yourself by not putting valuables inside your car, and also by parking in garages.
