Cars Being Stolen With Keyless Entry
Car owners who throw keys on tables or near their front doors may be unwittingly allowing thieves to hijack the signal. This relay attack is one of the high-tech methods criminals are employing to steal new keyless cars.
All keyless ignition cars emit an low-power radio signal that is looking for a matching fob to respond. If the signal is recorded and recreated, it could be used to unlock the car and then start it up.
Relay Attack
Imagine your car safely at your driveway, with your key fob inside your home. You might think that your car is safe however, sophisticated thieves are planning to steal your car without you being aware. These thieves use technology to snoop on vehicles through digital chinks. This method of stealing cars with keyless access is called relay theft.
Keyless entry cars are designed to function using a signal transmitted from the car's remote control (RF) transmitter to the owner's key fob. To stop keyless entry by intruders the RF transmitters on the key fob as well as the car are programmed only to turn on when they are within a specific distance of each other. A thief, however, is able to circumvent this restriction employing a method known as the "relay-attack".
Two people are required to do this: one stands close to the car and utilizes a device to capture an electronic version of the signal from the key fob. The other, standing by the home of the owner and using a second 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 unlock and begin the engine.
In the past, this kind of heist required expensive equipment to perform. However, now you can buy relay transmitters on the inexpensive online market and carry out a heist in minutes. This is the reason it's well-liked by car thieves.
While certain vehicles are less susceptible to this type of theft than others, all modern cars with keyless entry are vulnerable. Researchers have examined 237 well-known cars and found that all of them are susceptible to being stolen by this method.
Tesla vehicles are believed to be less susceptible to this kind of theft. However Tesla hasn't implemented UWB technology to allow it to perform distance checks and stop relay attacks. The company has said it will make this happen in the near future, but until then they are still vulnerable. This is why it's crucial to be proactive about your security in your car and install an anti-theft kit which protects your keys as well as your the car from such attacks.
CAN Injection Attack
Modern vehicles are designed to shield themselves from theft by exchanging cryptographic data with the key to prove that it's genuine. The system is thought to be secure, but criminals have found ways to circumvent it. They impersonate the smart key, then send messages to the vehicle and then drive away. To do this they have access to the smart key's internal communications network.
Most cars today are equipped with between 20 and over 200 electronic control units, also known as ECUs, which control various aspects of the vehicle's operation. They communicate with each other using the CAN bus. To keep power consumption low they ECUs enter the sleep mode at low power. This mode is activated when they receive a 'wake up frame. These frames are typically sent through the door or a smart key receiver ECU. However the messages aren't usually authenticated or encrypted, which means that they could be snatched by criminals using a cheap and simple device.
To accomplish this, they must look for a place where they can connect directly to the CAN bus wires. They are usually hidden inside the headlights or elsewhere in the front of the vehicle, and are accessible by removing the bumper and cutting holes in the headlamp assembly to expose them. The thieves employ an instrument known as a CAN injection attack to send fake messages which trick the car's safety systems to unlock and disable the engine immobilizer.
The devices are available on the Dark Web and work with most major car manufacturers which include 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 the issue in their current models. However, these criminals will continue to take any opportunity they can. We can stop this by installing mechanical safety measures like Discloks in all of our cars and parking them in well-lit, well-lit areas.
The Signal is blocked
In a different variation of the relay attack, thieves could make use of a device to block the signal that is sent by the key fob when the vehicle is locked. The device could be found inside the pocket of a thief in a parking lot or in a hidden spot close to the driveway that is being targeted. The owners don't know whether the vehicle is locked when they press the lock button. The device used by the criminal blocks the signal that locks the car. Thus, thieves are able to leave the vehicle.
The crooks also use devices to amplify the key fob's signals in order to unlock vehicles. The crooks can do this even if the key is in the driver's pocket, or hanging from a hook inside the home. After the car is unlocked, hackers can make use of 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. However, thieves are always trying to beat these measures.
They've started 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 then start the car using this fake signal.
This technique is particularly popular in the US where a lot of cars are equipped with wireless technology. Owners can unlock and start their vehicle through a mobile application on their smartphone. This technology is expected to become increasingly popular as more and more companies try to connect their vehicles with their owner's smartphones.
In addition to installing anti-theft technologies in vehicles, it's vital for drivers to leverage best practices when they park their vehicles. They shouldn't leave their keys in the ignition, should always ensure that the car is securely locked when they're not in it and should utilize an engine or steering wheel lock, if it is possible. They should also think about installing a tracking device onto their vehicle in case it is stolen.
Flat Battery
This type of attack occurs more often than most people realize. The thieves use low-cost devices that increase the signal from your key fob to unlock and start your car if it is off. Then they drive the vehicle to a trailer or around a corner to take the vehicle away. It would be possible to protect your car from this by installing an interrupter switch car stolen without key for the starter circuit. The simplest ones just have an ON/OFF switch that interrupts the starter circuit. It costs about $15 and is simple enough to install by yourself.
Car thieves are always working on new ways to get into vehicles and then steal them. The police, car makers and insurance companies are always trying to keep up with their strategies and offer better anti-theft solutions for modern vehicles. However, that doesn't stop thieves, who are able to be quick to adapt and discover ways to bypass the latest anti-theft measures.
Many thieves jam the signal by using devices that use the same radio frequency of the fob. They put the device in their pocket or in a location close to their vehicle, and it prevents the fob's lock commands from reaching the vehicle, leaving the vehicle unlocked. This can be done within minutes. The device is inexpensive and is available on the internet.
Hacking the computer system of the car is an alternative option. This is more difficult, but possible. All cars have an diagnostic port and hackers have designed devices that connect to them and let them access the software in the car. From there, they can program a blank key fob and start working. It is also possible to do this on older vehicles, however it is more difficult to do without removal of the ignition lock.
As more vehicles are connected to drivers' phones the method is likely to become more popular too. Once a burglar has access to the username and password to a vehicle app and is able to unlock or start the vehicle by using the app. Fortunately, you can defend yourself from these kinds of attacks by not putting valuables in your car and parking it in a secure garage or parking lot.
