Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or near their doors, they could not realize that they are allowing thieves to steal their signal. This relay attack is just one of the advanced methods criminals are employing to steal new keyless vehicles.
All keyless ignition cars emit an low-power radio signal that is seeking a compatible fob that can respond. If the signal is recorded and recreated, it can be used to unlock the car and start it up.
Relay Attack
Imagine your car safely in your driveway, and your key fob in your home. You may think your car is secure, but sophisticated thieves are planning a heist, without you knowing. The thieves employ technology to hack into vehicles via digital chinks. This is known as relay theft, it's an increasingly common method of stealing vehicles that have keyless entry.
Cars with keyless entry are designed to operate via an electronic signal that is sent from the remote control (RF) transmitter to the owner's key fob. To ensure that keyless entry is not unauthorized the RF transmitters on the key fob and in the car are programmed to activate only when they're within certain distance from one another. However, thieves are able to overcome this limitation using a technique known as the'relay attack'.
To do so two people work together: one stands by the car with a device that captures an electronic version of the key fob's signal. The other, who is at the owner's home is using a second device to transmit the signal from the key fob back to the car. This trick tricks the car into thinking the key fob is close enough to allow it to unlock and begin the engine.
This type of heist used to require expensive equipment. Today, you can purchase a relay transmitter for a small price online and carry out an heist in a matter of minutes. This is the reason why car thieves are enthralled by it.
While certain vehicles are less vulnerable to this kind of theft than others, all modern cars with keyless entry are at risk. Researchers have examined 237 well-known cars and found that all of them are susceptible to being stolen using this method.
Tesla vehicles are supposedly less susceptible to this type of theft, but the company hasn't yet implemented UWB features that would effectively check distances on the car's signal and prevent relay attacks. The company has stated that they will implement this in the near future, however until then they are vulnerable. This is why it's crucial to be proactive about your car security and install an anti-theft device that safeguards your keys and vehicle from these kinds of attacks.
CAN Injection Attack
Modern cars can guard themselves against thieves by exchanging encrypted messages with the key in order to confirm its authenticity. This method is generally thought to be secure, however thieves have found a way to circumvent it. They pretend to be the smart key, then send messages to the vehicle, and then drive off. To accomplish this, they have access to the smart keys' internal communication network.
Nowadays, the majority of cars are fitted with between 20 to 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate using an electronic network known as CAN bus. To keep power consumption low the ECUs are put into the sleep mode at low power. This mode is activated when they receive a wake up' frame. These frames typically come from the door or smart key receiver ECU. These messages aren't always encrypted or authenticated. This means that criminals are able to intercept them with a simple and cheap device.
They search for a spot where they can connect directly to the wires of the CAN connection. They are usually hidden in the headlights, or in other areas of the front of the vehicle. To access them, you must pull the bumper and cut holes in the headlamp assemblies. The thieves employ an instrument known as an CAN injection attack. It is used to send out fake messages that can trick the security systems of the car into unlocking and disengaging the engine immobilizer.
These devices can be bought through 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 makers address the issue in their current models. However, the thieves will continue to steal any opportunity they can. The best thing we can do is to try and prevent this by installing security measures that are mechanical like Discloks on all our vehicles, and making sure that they are placed in areas that are well-lit and are clearly visible to people passing by.
Jamming the Signal
In a variant of the relay attack, which makes use of a device that can be used to block the signal from the key fob when the car is locked. The device could be found in the pocket or hiding where a burglar is hiding on the parking lot, or near the driveway that is being targeted. Owners don't check whether the vehicle is locked when they press the lock button. The device used by the criminal block the signal that locks the vehicle. Therefore, thieves can drive away with the vehicle.
The crooks also make use of devices to amplify the signal from the key fob to unlock vehicles. The crooks are able to do this even when the key is inside 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 create a blank fob.
Car manufacturers have developed various anti-theft devices to safeguard against these types of attacks. 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 can then copy the unlock code of the key fob and start the car with this fake signal.
This method is very popular in the US and Europe where a lot of automobiles are equipped with wireless technology that allows owners to unlock and start their cars with a mobile app on their smartphone. This technology is likely to become increasingly popular as more and more companies attempt to link their vehicles to their owners' smartphones.
In addition to incorporating anti-theft technology in vehicles, it's crucial for drivers to follow the best practices when parking their cars. 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 make use of the steering wheel or a gearstick lock, if they can. They should also think about fitting a tracking device to their vehicle in case it's stolen.
Flat Battery
This kind of attack happens more often than people realize. Thieves make use of cheap devices read more to extend the signal from your key fob to unlock and begin cars even if they're shut off. Then they drive the car to the trailer or around a corner, and take it away. Installing a starter circuit interruption switch can protect your vehicle from this. Simpler versions have an ON/OFF button which interrupts the circuit. It costs about $15 and is simple enough to install yourself.
Car thieves are always looking for new ways to gain access to vehicles and steal them. The police, car makers and insurance companies are always trying to catch up to their tactics and offer better anti-theft solutions for modern cars. But that doesn't stop thieves who are able adapt quickly and discover ways to bypass the most recent anti-theft measures.
A lot of thieves block the signal with a device that uses the same radio frequency of the fob. They put the device in their pockets or close to their vehicle, and it stops the fob's lock signal from reaching the car which leaves it unlocked. This can be done in just a few seconds. The device is affordable and easily accessible online.
Hacking the computer system of the car is an alternative option. This is harder but still feasible. Every car has a diagnostic port, and hackers have designed devices that plug into them and allow them access the software in the car. From there, they are able to program the blank key fob to make it work. This is also possible on older vehicles, however it is more difficult to do so without removing the ignition lock.
As more vehicles are linked to smartphones of drivers and this method could become more popular as well. Once a criminal has the username and password for the vehicle app they are able to unlock or start the car with the app on their phone. You can safeguard yourself by not putting valuables inside your car, and also by parking in a garage.
