Cars Being Stolen With Keyless Entry
Car owners who throw their keys on a table or near their front doors could be giving thieves the ability to take over the signal. This relay attack is just one of the advanced methods criminals are using to steal brand new keyless cars.
Keyless ignition vehicles emit a low power radio signal to find a matching fob. If the signal is recorded and recreated, it could be used to unlock the car and to start it.
Relay Attack
Picture your car parked securely in the driveway, with the key fob tucked away in your home. You may be confident that your car is safe but sophisticated thieves are planning a heist, without you knowing. These thieves use technology to hack into vehicles via digital chinks. This method of stealing cars that have keys is known as relay theft.
Cars equipped with keyless entry are designed to function using a signal that is transmitted from the car's remote control (RF) transmitter to the owner's key fob. To stop keyless entry by unauthorized individuals the RF transmitters that are on the key fob as well as the car are programmed to turn on when they are within a specified distance from each other. However, thieves can bypass this restriction by using a technique known as the'relay-attack'.
To accomplish this two people work together: one stands by the car and uses a device that captures digitally the key fob's signal. The other, who is at the owner's house is using a different device to transmit the key fob's signal to the car. This trickery tricks the car into thinking that the key fob has traveled an adequate distance to unlock and start the vehicle.
In the past, this kind of heist required expensive equipment to perform. It is now possible to purchase a relay transmitter for a small price online and pull off a heist within minutes. This is the reason why car thieves love it.
While some cars are less vulnerable to this type of theft than others, all modern vehicles with keyless entry are at risk. Researchers have examined 237 well-known cars and found that every one of them could be taken through this method.
Tesla vehicles are believed to be less vulnerable to this kind of theft. However Tesla hasn't yet implemented UWB technologies that would allow it to perform distance checks and stop relay attacks. The company has said it will implement this feature in the near future, but for now, they remain vulnerable. That is why it's important to take a proactive approach to your security in your car and install an anti-theft kit that protects your keys and vehicle from these kinds of attacks.
CAN Injection Attack
Modern cars can protect themselves from thieves by transferring encrypted messages using the key to confirm its authenticity. The system is generally believed to be secure, however thieves have found a way to circumvent it. They simply pretend to be the smart key and send other messages to the vehicle letting it unlock the doors, turn off its engine immobilizer, and then go on their way. To do that they gain access to the smart key's internal communication network.
Today, most cars 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 with each other via an electronic network referred to as CAN bus. These ECUs are put into a low power sleep mode to decrease their power consumption. This mode is activated when ECUs receive a "wake up" frame. These frames are typically sent via the door or smart key receiver ECU. These messages are not always authenticated or encrypted. This means that criminals are able to intercept them with an inexpensive and simple device.
They look for a place where they can connect directly to the wires of the CAN connection. They usually hide in the headlights or in other locations in the front of the vehicle. To access them, you can remove the bumper and cut holes read more in the headlamp assemblies. The criminals then employ a device dubbed an CAN injection attacker to send fake messages which can trick the car's security systems into unlocking it and disengaging its engine immobilizer.
These devices can be bought through the Dark Web and work with all major car makers, 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 in their existing models. However, these thieves will continue to steal everything they can. We can stop this from happening by installing mechanical safety measures, such as Discloks inside every car we own and parking them in well-lit, visible areas.
Jamming the Signal
In a variant of the relay attack that uses a gadget, thieves can jam the signal transmitted by a key fob while the vehicle is locked. The device could be found in the pocket or hiding place of a thief on a parking lot, or near the driveway being targeted. When owners hit the lock button on their fobs and walk away they don't consider whether or not their car is actually locks. The device of the crook blocks the signal that locks the car. Therefore, thieves can drive away with the vehicle.
They also have devices that amplify signals from the key fob to unlock vehicles. The crooks can accomplish this even when the key is in a driver's pocket, or hanging from a hook inside the home. After the car is unlocked, hackers can make use of an ordinary diagnosis port to program an unlocked fob.
To guard against this kind of attack, car manufacturers have developed a variety of anti-theft gadgets. However, criminals are constantly looking for ways to defeat these measures.
They've been using devices that transmit at the same frequency as remote keyfobs to intercept signals. The crooks then copy the key fob's unlock code and then start the car using this fake signal.
This method is especially popular in the US in which many vehicles have wireless technology. Owners can start and unlock their car through a mobile application on their phone. This technology is likely to gain popularity as more and more companies attempt to connect their vehicles to their owners' smartphones.
It is crucial that drivers follow the best practices to park their cars. They shouldn't leave their key fobs in the ignition. They should always ensure that the car is fully locked when they're not in it and should utilize the steering wheel or a gearstick lock, if it is possible. They should also think about having a tracking device fitted to their vehicle in the event that it's stolen.
Flat Battery
This kind of attack is more prevalent than people think. The thieves make use of low-cost devices that increase the signal of your key fob to enable it to unlock and start your car even if it is off. Then, they drive the car to an unmarked trailer or around a corner to take the vehicle away. Installing an interruption switch to the starter circuit will protect your vehicle from this. Simpler versions come with an ON/OFF button which interrupts the circuit. It's about $15 and is simple to install.
Car thieves are constantly searching for new ways to rob vehicles. Police, car manufacturers and insurance companies are always trying to stay abreast of the latest techniques and offer more effective anti-theft systems for modern vehicles. But this doesn't stop thieves who can be quick to adapt and find ways around the latest anti-theft technology.
For instance, many thieves use devices that operate on the same radio frequency as the fob to jam the signal. The device is put in the pocket or close by the vehicle, and stops the fob from sending the lock command to the vehicle. This can be done in a matter of seconds. The device is inexpensive and readily available on the internet.
Hacking the computer system of the car is an alternative option. This is more difficult but nevertheless feasible. Every car has a 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 start working. This is also possible on older vehicles, however it is more difficult without removing the ignition lock.
As more vehicles are connected to smartphones of drivers and this method could become more popular as well. Once a thief has the username and password to a vehicle application, they can unlock or start the vehicle using the app. You can safeguard yourself by not putting valuables inside your car, and also by parking in a garage.
