Cars Being Stolen With Keyless Entry
Car owners who throw their keys on a table or in front of their front door could be allowing thieves to hijack the signal. This relay attack is one of the advanced methods criminals are employing to steal new keys from cars.
Keyless ignition vehicles emit a low-power radio signal to find an appropriate fob. If the signal can be captured and recreated, it can be used to unlock the car and start it.
Relay Attack
Imagine your car safely at your driveway, with your key fob inside your home. You may be confident that your car is safe but sophisticated thieves are planning a heist, without you being aware. Instead of breaking windows or jimmying locks, thieves are leveraging technology to gain access to cars through digital cracks in their armor. This method of stealing vehicles with keys is known as relay theft.
Cars with keyless entry are designed to operate via a signal sent from the car's remote control (RF) transmitter to the owner's key fob. To prevent unauthorized keyless entry, the RF transmitters in the key fob as well as in the car are programmed to activate only when they're within a certain distance from one another. However, thieves is able to circumvent this restriction employing a method known as the "relay-attack".
Two people are required to complete this: one person is close to the car and utilizes a device to capture an electronic version of the signal from the key fob. The other who is at the home of the owner is using a second device to transmit the signal from the key fob to the car. This trick tricked the car into thinking the key fob is near enough to be able to unlock it and start the engine.
In the past, this type of heist required expensive equipment to perform. But now, you can pick up relay transmitters on the cheap online and execute an heist in a matter of minutes. This is why it's popular among car thieves.
While certain cars are less susceptible to this kind of theft than others, all modern vehicles that have keyless entry are vulnerable. Researchers have tested 237 popular automobiles and found that all of them could be taken using this method.
Tesla vehicles are supposedly less vulnerable to this type of theft, however, the company has not yet implemented UWB features that would effectively perform distance checks on the car's signal to protect against relay attacks. The company has said that they'll implement this in the future but until then, they are vulnerable. Installing an anti-theft system that guards your car and your keys against such a threat is a proactive method to ensure the security of your vehicle.
CAN Injection Attack
Modern cars can guard themselves against thieves by exchanging encrypted messages with the key in order to prove its authenticity. The system is thought to be secure, however criminals have found ways to circumvent it. They just impersonate the smart key, and send other messages to the car letting it unlock the doors, turn off its engine immobilizer, then let them go on their way. To do this, they gain access to the smart keys' internal communication network.
The majority of cars today are fitted 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 one another using an electronic network referred to as CAN bus. These ECUs enter a low power sleep mode to reduce their power consumption. This mode is activated when ECUs receive an "wake up" frame. These frames typically come via the door or smart key receiver ECU. However, these messages aren't always authenticated or encrypted and, therefore, can be intercepted by criminals using a cheap and simple device.
To do this, they look for a location that allows them to connect directly to the CAN bus connector wires. They're usually hidden in the headlights or in front of the vehicle, and can be accessed by pulling the bumper and cutting holes in the headlamp assembly to expose them. The thieves employ an instrument known as an CAN injection attack. It is used to send fake messages which fool the safety systems of the car to unlock and car stolen keys in car insurance disable the engine immobilizer.
The devices are available for sale on the Dark Web, and work for most of the major car manufacturers, including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and many more. The researchers who discovered this CAN Injection attack are recommending that all car makers address the issue in their current models, but the reality is that thieves will continue to steal whatever they can get their hands on. The best we can do is attempt to stop this from happening by installing mechanical security measures like Discloks on our vehicles, and making sure that they are always parked in well-lit areas that are clearly visible to people passing by.
Jamming the Signal
In a variation of the relay attack that employs a device, thieves can jam the signal sent by a key fob while the vehicle is locked. The device could be 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 car is locked after pressing the lock button. The device used by the criminal blocks the signal that locks the car. Therefore, thieves could escape with the car.
They also make use of devices that amplify signals from the key fob to unlock vehicles. The crooks can accomplish this even when the key is inside a driver's pocket, or hanging from a hook inside the home. Once the car has been locked, hackers can use a standard diagnosis port to program the fob with a blank.
To safeguard against this kind of attack, car makers have come up with a range of anti-theft devices. But, thieves are constantly trying to beat these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs to intercept signals. The thieves then copy the unlock code of the key fob and start the vehicle with this fake signal.
This technique is particularly popular in the US where a lot of cars have wireless technology. Owners can start and unlock their car using a mobile application from their mobile. This technique is likely to be more commonplace as more companies attempt to connect their cars to their owners' smartphones.
In addition to installing anti-theft technologies in vehicles, it's vital for drivers to use the best practices when they park their vehicles. They should not leave the keys in ignition and should always lock the car when they are not in it. If they can, they should also use a gearstick lock or steering device. They should also consider installing a tracking device on their vehicle in the event that it's stolen.
Flat Battery
This kind of attack happens more often than most people realize. The thieves employ inexpensive devices that extend the signal of your key fob to unlock and start your car, even in the event that it is off. Then, they drive the car to an unmarked trailer or around a corner and take it away. It would be possible to protect your car from this by installing a starter circuit interrupt switch. Simpler versions come with 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 then steal them. 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. But that doesn't stop the thieves, who are able to adapt quickly and discover ways to bypass the latest anti-theft measures.
For instance, many criminals use a device that works on the same radio frequency as the fob to jam the signal. The device is tucked away in the pocket or near the vehicle, and stops the fob from sending the lock command to the car. This can be done within minutes. The device is affordable and is available on the internet.
Another tactic is to hack into the car's computer system. This is more difficult but still possible. Hackers have created devices that plug into the diagnostic port of all vehicles and permit them to connect to the software. They can then program a blank fob to work. It is also possible to do this on older vehicles, however it is more difficult to do without removing the ignition lock.
As more vehicles are linked to drivers' phones, this method may become more popular too. Once a criminal has the username and password for an app for vehicles they are able to unlock the car or start it using the app on their phone. Fortunately, you can protect yourself from these types of attacks by not putting valuables in your car and putting it in a garage or secure parking lot.
