Cars Being Stolen With Keyless Entry
Car owners who leave their keys on tables or in front of their front door could be giving thieves the ability to take over the signal. This relay attack is one of the advanced methods criminals are employing to steal new keyless cars.
All keyless ignition vehicles emit a low power radio signal to find an appropriate fob. If the signal is captured and recreated, it could be used unlock the car, and also to start it.
Relay Attack
Picture your car parked securely in the driveway, and the key fob tucked away in your home. You may think your car is safe but sophisticated thieves are planning to steal your car without you knowing. Instead of slamming windows and jiggling locks, thieves are leveraging technology to gain access to cars through digital chinks in their armor. This method of stealing cars that have keyless access is known as relay theft.
Cars equipped with keyless entry are designed to function using an electronic signal that is transmitted by the car's remote control (RF) transmitter to the owner's key fob. To ensure that keyless entry is not unauthorized, the RF transmitters in the key fob and car are programmed to activate only when they're within certain distance from one another. A thief, however, can bypass this restriction by employing a technique called the relay-attack.
To do so, 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 home with the owner is using a second device to transmit the signal from the key fob back to the car. This trickery fools the car into thinking that the key fob is at a distance sufficient to unlock and start the vehicle.
This type of attack was once a costly process that required expensive equipment. But now, you can purchase relay transmitters for low cost online and conduct the heist in just a few minutes. This is why it's so well-liked by car thieves.
All modern vehicles that have keyless access are vulnerable. Certain vehicles are more susceptible to this type of attack than others. Researchers have tested 237 popular cars and found that all of them could be taken using 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 attacks via relay. The company has said it will implement this feature in the near future, but until then, they remain vulnerable. Installing an anti-theft system that protects both your car keys and your keys against these types of attacks is a proactive way to ensure the security of your vehicle.
CAN Injection Attack
Modern cars can protect themselves from thieves by transferring encrypted messages using the key to confirm its authenticity. The system is considered to be safe, but criminals have found ways to circumvent it. They can impersonate the smart key, and send messages to the vehicle letting it unlock the doors, disable its engine immobilizer, and let them go on their way. To do this, they get access to the smart key's internal communication network.
Today, most cars are equipped with between 20 and 200 electronic control units, also known as ECUs, that control different aspects of the vehicle's operation. They communicate via a network called CAN bus. To ensure that power consumption is low, these ECUs enter sleep mode with low power that is activated when they receive a wake up' frame. These frames are typically sent from the door or smart key receiver ECU. These messages are not always authenticated or encrypted. This means that criminals can take them over with a simple and cheap device.
They search for a spot that allows them to connect directly to the CAN connection wires. These are often hidden away inside the headlights or elsewhere in front of the car, and can be accessed by pulling the bumper off and cutting holes in the headlamp assembly to expose the wires. The thieves then use a device called an CAN injection attacker, which is used to send out fake messages that fool read more the security systems of the car to unlock it and disable its engine immobilizer.
The devices are available on the Dark Web and work with the majority of 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 manufacturers fix this in their existing models. However, these thieves will continue taking everything they can. The best thing we can do is to attempt to stop this from happening by putting in mechanical security measures such as Discloks on all of our vehicles, and making sure that they are always placed in areas that are well-lit and are easily visible to pedestrians.
Blocking the Signal
In a variant of the relay attack that makes use of a device that can be used to block the signal from key fobs while the car is locked. The device could be found in the pocket or hiding where a burglar is hiding on the parking lot, or even near the driveway that is being targeted. When owners press the button to lock their fobs and walk away, they don't think about whether or not their car is really is locked. Instead, thieves could drive off with the vehicle because the signal that normally locks the car is blocked by the device of the criminal.
They also make use of devices that amplify signals from the key fob to unlock vehicles. The crooks can do this even if the key is inside a driver's pocket, or hanging on an outside hook in the home. Once the car is locked, they can use a standard computer hacker to program the blank key fob and gain control of the vehicle.
Automobile manufacturers have developed various anti-theft devices to guard against these kinds of attacks. However, criminals 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 to intercept their signals. The thieves copy the unlock code of the key fob and start the vehicle with this fake signal.
This method is very popular in the US and Europe where a lot of cars 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 become increasingly popular as more and more companies attempt to connect their vehicles with their owner's smartphones.
In addition to implementing anti-theft systems in vehicles, it's crucial for drivers to follow the best practices when parking their vehicles. They should never leave their keys in the ignition. They should always make sure the vehicle is locked completely when they're not in it and should utilize an engine or steering wheel lock, if it is possible. They should also think about fitting a tracking device to their vehicle in the event that it is stolen.
Flat Battery
This kind of attack is more prevalent than many people believe. The thieves use low-cost devices that increase the signal from your key fob to enable it to unlock and start your car, even in the event that it is off. Then they drive the car to the trailer or around a corner and take the vehicle away. Installing an interrupter switch for the starter circuit will protect your vehicle from this. The simplest ones just have an ON/OFF switch that interrupts the starter circuit. It costs around $15 and is simple to install.
Car thieves are constantly looking for new ways to rob vehicles. The police as well as car manufacturers and insurance companies are always trying to catch up with their strategies and provide better anti-theft systems for modern cars. However, this does not stop thieves who are able to adapt quickly and find ways to circumvent the latest anti theft measures.
A lot of thieves block the signal using devices that use the same radio frequency of the fob. The device is placed in the pocket or close to the vehicle, and stops the fob from transmitting the lock command to the vehicle. This can be accomplished in just a few seconds. The device is inexpensive and available on the internet.
Hacking the computer system of the car is another option. This is more difficult but it is still feasible. Every car has an diagnostic port and hackers have designed devices that plug into them and let them access the car's software. They can then program an unfinished fob to work. It is also possible to do this on older cars, although it is more difficult to do so without removal of the ignition lock.
As more vehicles are connected to the phones of drivers the method is likely to become more popular too. Once a thief has the username and password to a vehicle application, they can unlock or start the vehicle by using the application. It is possible to be safe from these kinds of attacks by not leaving valuables in your car and putting it in a garage or secure parking lot.
