Cars Being Stolen With Keyless Entry

Car owners who throw their keys on a table or near their front doors may be unwittingly permitting thieves to steal the signal. This relay attack is just one of the latest techniques criminals are using to steal new keys from cars.

All keyless ignition cars emit a low-power radio signal looking for a matching fob to respond. If the signal is captured and recreated, it could be used to unlock the car and begin it up.

Relay Attack

Imagine your car parked in your driveway with your key fob at home. You're confident that your car is safe, but not seen by you, sophisticated thieves are plotting an heist. Instead of slamming windows or jiggling locks, they are leveraging technology to hack into cars via digital cracks in their armor. This method of stealing cars with keyless access is known as relay theft.

The keyless entry system in cars is controlled by a signal sent by the car's RF transmitter to the key fob. To prevent unauthorized keyless entry the RF transmitters on the key fob and car are programmed to activate only when they're within a specific distance of each other. However, a thief can override this restriction using a technique known as the'relay attack'.

Two people are required to do this: one stands near the car and utilizes a device to capture digitally the the key fob. The other, standing by the house of the owner is using a different device to send the key fob's signal to the car. This trick tricked the car into thinking that the key fob is close enough to be able to unlock it and start the engine.

In the past, this type of heist required expensive equipment to carry out. You can now buy a relay transmitter for a small price on the internet and complete an heist in a matter of minutes. This is why car thieves are enthralled by it.

All modern vehicles that have keys are at risk. Some cars are more susceptible to this type of attack than others. Researchers have tested 237 of the most popular cars and found that every one of them are susceptible to being stolen through this method.

Tesla cars are said to be less susceptible to this type of theft, but Tesla hasn't yet implemented UWB features that would effectively perform distance checks on the car's signal and prevent relay attacks. The company has said that they will implement this in the near future, but until then, they are vulnerable. That is why it's important to take a proactive approach to your vehicle security and install an anti-theft tool that protects your keys and the car from such attacks.

CAN Injection Attack

Modern cars can guard themselves against thieves by transferring encrypted messages using the key to verify its authenticity. The system is generally believed to be secure, but thieves have found a way to circumvent it. They can pretend to be the smart key and send messages to the car, letting it unlock the doors, disable its engine immobilizer, and let them go on their way. To do this 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, or ECUs, which control various aspects of the vehicle's operation. They communicate with one another using the CAN bus. To keep power consumption low they ECUs go into sleep mode with low power that is activated when they receive a 'wake up frame. These frames are usually sent by the ECU that manages the smart key or door. However they aren't always encrypted or authenticated so they could be snatched by criminals who have a low-cost and basic device.

They look for a place where they can connect directly to the wires of the CAN connection. They're usually hidden within the headlights or in the front of the car, and are accessible by removing the bumper and cutting holes in the headlamp assembly to expose them. The thieves then employ a device known as a CAN injection attacker to send fake messages that fool the security systems of the car into unlocking the car and disengaging the engine immobilizer.

The devices are available on the Dark Web and work with most major car manufacturers including BMW and Cadillac, Chrysler, Fiat and Ford, Honda, Hyundai and Jeep, Lexus and Nissan, Renault and Toyota, Volkswagen and Maserati. The researchers who discovered this CAN Injection attack are recommending that all car makers address the issue in their current models, but the fact is that the thieves will continue to grab everything they can lay their hands on. The best we can do is make an effort to prevent this from happening by putting in mechanical security measures like Discloks on all our vehicles and ensuring that they are parked in well-lit areas that are clearly visible to passers-by.

Blocking the Signal

In a variant of the relay attack, which makes use of a device, thieves can jam the signal sent by a key fob while the car is locked. The device could be hidden in the pocket or hidden place of a thief on an open parking lot or even near the driveway that is being targeted. Owners aren't able to verify whether their vehicle is locked after pressing the lock button. Instead, thieves are able to escape with the vehicle because the signal that normally locks the car is blocked by the crook's device.

They also use devices that amplify signals from the key fob to unlock vehicles. They can even accomplish this if the key is in the pocket of the driver or hanging from a hook in the home. After the car is locked, hackers can use the standard diagnostic port to program an unlocked fob.

To safeguard against this kind of attack, car makers have created a variety of anti-theft devices. But, as always, thieves come up with ways to thwart these measures.

They've started using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The crooks can then copy the unlock code of the key fob and then start the car using this fake signal.

This method is especially popular in the click here US, where many cars come with wireless technology. Owners can unlock and start their vehicle using a mobile application from their mobile. This technology is likely to be more commonplace as more car manufacturers attempt to connect their cars to their owners smartphones.

In addition to installing anti-theft technologies in vehicles, it's crucial for drivers to follow the best practices when they park their vehicles. It is not a good idea to leave keys in the ignition, and should always ensure that their car is fully locked when they're not in it and should make use of a steering wheel or gearstick lock, if they can. They should also consider having a tracking device fitted to their car in the event it gets stolen.

Flat Battery

This kind of attack happens more often than people realize. Thieves use cheap devices to extend the signal from your key fob to open and start cars even if they're shut off. Then they drive the vehicle to a trailer or around a corner and take the car away. It would be 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's about $15 and is simple enough to put in yourself.

Car thieves are always looking for new ways to enter vehicles and take them away. 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. But that doesn't stop the thieves, who are able to 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 put the device in their pocket or somewhere close to their vehicle, and it prevents the fob's lock command from reaching the car and thereby leaving the vehicle unlocked. This can be accomplished in a matter of minutes. The device is inexpensive and easily accessible online.

Another option is to hack the car's computer system. This is more difficult but still feasible. Every car has an diagnostic port, and hackers have created devices that plug into them and allow them access the car's software. From there, they are able to program the blank key fob to start working. It is possible to do this with older cars as well, but it's more difficult without taking out the ignition.

This method is likely to become more popular if more vehicles are connected with drivers' phones. Once a burglar has access to 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 in your car and by parking in a garage.
