Cars Being Stolen With Keyless Entry
If car owners leave their keys on the table or near their doors, they may unknowingly be allowing thieves to hijack their signal. This relay attack is one of the latest techniques criminals are using to steal brand new keys from cars.
All keyless ignition cars emit an low-power radio signal that is looking for a matching fob to respond. If the signal can be recorded and recreated, it could be used unlock the car and to start it.
Relay Attack
Picture your car parked securely in the driveway, with the key fob safely inside your home. You're sure that your car is safe, but unnoticed by you, sophisticated thieves are plotting an heist. Instead of slamming windows or jiggling locks, they are leveraging technology to hack into vehicles using digital cracks in their armor. Known as relay theft, it's an increasingly popular method of stealing cars with keyless entry.
Keyless entry cars are designed to operate via a signal sent from the remote control (RF) transmitter to the owner's key fob. To ensure that keyless entry is not accessed by intruders the RF transmitters on the key fob and the car are programmed only to turn on when they are within a specific distance from one another. However, thieves can bypass this restriction by employing a technique called the "relay-attack".
Two people are required to do this: one person stands near the car and uses a device to capture an electronic version of the signal from the key fob. The other who is at the owner's home is using a second device to transmit the signal from the key fob to the car. This trickery tricks the car into believing the key fob is at a distance sufficient to allow it to be opened and started the vehicle.
This type of heist was once a costly process that required expensive equipment. 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 the reason it's well-liked by car thieves.
While certain vehicles are less susceptible to this kind of theft than others, all modern vehicles that have keyless entry are vulnerable. In fact, researchers have tested 237 popular vehicles and found that they can all be stolen using this method.
Tesla vehicles are said to be less vulnerable to this kind of theft. However Tesla hasn't implemented UWB technology that would allow it to perform distance checks and stop relay attacks. The company has stated that they'll implement this in the near future, but until then, they're vulnerable. Installing an anti-theft system that safeguards your car keys and your keys against such attacks is a proactive way to ensure the security of your car.
CAN Injection Attack
Modern cars are designed to guard themselves from theft by transferring cryptographic messages using the key to prove it's authentic. The system is believed to be secure, but thieves have found ways to get around it. They can impersonate the smart key, and send messages to the vehicle letting it unlock the doors, disable its engine immobilizer, then let them leave the car. To do this, they gain access to the smart keys' internal communications network.
The majority of cars today are fitted with between 20 and over 200 electronic control units, or ECUs, which control various aspects of the vehicle's operation. They communicate through an electronic network known as CAN bus. To reduce power consumption, these ECUs are put into sleep mode with low power that is activated when they receive a wake up frame. These frames are typically sent by the ECU that is in charge of the smart key or door. These messages are not always authenticated or encrypted. This means that criminals can intercept them with a simple and cheap device.
They look for a place where they can connect directly to the CAN connection wires. They are usually hidden in the headlights or in other places in the front of the vehicle. To gain access to them, you can remove the bumper and make holes in the headlamp assemblies. The criminals then employ a device known as a CAN injection attacker to send out fake messages that can trick the car's security systems into unlocking the car and disengaging the engine immobilizer.
The devices are available for sale on the Dark Web, and work for most of the major car manufacturers which include BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and more. Researchers who have discovered the CAN Injection attack recommend that all car manufacturers fix this issue in their existing models. However, these criminals will continue to take everything they can. We can stop this by installing mechanical security measures, such as Discloks inside all our vehicles and parking them in well-lit and visible areas.
Blocking the Signal
In a different variant of the relay attack, thieves may employ a device to block the signal sent from the key fob when the car is locked. The device could be found hidden in the pocket of a thief in a parking lot or in a hideout near the driveway that is being targeted. When owners hit the button to lock their fobs and walk away and leave, they don't have to think about whether or not the car really is locked. The device used by the crook block the signal that locks the vehicle. Therefore, thieves can escape with the car.
The crooks also use devices to enhance the signal of the key fob in order to unlock vehicles. They can do this when the key is in the pocket of the driver or hanging from its hook inside the house. Once the car is unlocked, they can use a standard diagnostic port or computer hackers to program the blank key fob and gain control of the vehicle.
Automobile manufacturers have developed a range of anti-theft systems to protect against these types of attacks. But, as always, thieves come up with ways to thwart these measures.
They've been using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The thieves can then copy the key fob's unlock code and start the car with this fake signal.
This technique is especially popular in the US and Europe where many cars are equipped with wireless technology that lets owners unlock and start their vehicles by using a mobile application on their phone. This technology is likely to become more popular as more and more companies try to connect their vehicles to owners' smartphones.
In addition to incorporating anti-theft technology in vehicles, it's vital for drivers to use the best practices when they park their cars. It is not advisable to leave the keys in ignition and lock the car when they are not in it. If possible, they should also use a gearstick lock or steering device. It is also recommended to consider installing a tracking device to their car in the event it's stolen.
Flat Battery
This kind of attack occurs more often than people realize. The thieves use cheap devices that extend the signal from your key fob in order to unlock and start your car, even when it's off. They then drive the car around a corner or onto a trailer to leave with it. Installing an interrupter switch for the starter circuit would protect your car against this. The simplest ones just have an ON/OFF switch that interrupts the starter circuit. It's about $15 and is easy enough to install yourself.
Car thieves are always searching for new ways to steal vehicles. Car manufacturers, police and insurance companies are always trying to stay on top of the latest tactics and provide more effective anti-theft systems for modern vehicles. But this isn't stopping thieves who be quick to adapt and find ways around the most recent anti-theft measures.
A lot of thieves block the signal with a device that uses the click here same radio frequency of the fob. The device is tucked away in the pocket or close to the vehicle and blocks the fob from sending the lock command to the car. This can be done within minutes. The device is affordable and easily available on the internet.
Another option is to hack into the car's computer system. This is harder but still feasible. Hackers have created devices that connect to the diagnostic port of all cars and allow them to access the software. From there, they are able to program the blank key fob to start working. It is also possible to do this on older cars, although it is more difficult to do so without taking off the ignition lock.
This method could be more popular if more vehicles are connected to drivers' mobile phones. Once a criminal has access to the username and password to an application for vehicles they can open or start the vehicle by using the app. You can safeguard yourself by not putting valuables in your car and also by parking in garages.
