Cars Being Stolen With Keyless Entry
Car owners who throw their keys on tables or near their front doors may be unwittingly permitting thieves to steal the signal. This relay attack is one of the advanced methods criminals are using to steal new keyless cars.
Keyless ignition vehicles emit a low power radio signal to locate an appropriate fob. If the signal is recorded and recreated, it could be used to unlock the car and start it up.
Relay Attack
Imagine your car being parked safely in the driveway, with the key fob tucked away inside your home. You're sure that your car is safe, but not seen by you sophisticated thieves are planning an heist. Instead of slamming windows or jiggling locks, thieves are using technology to hack into cars via digital cracks in their armor. This method of stealing vehicles with keys is known as relay theft.
Keyless entry cars are designed to function using an electronic signal that is transmitted by 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 and car are programmed to activate only when they're within certain distance from one another. However, thieves is able to circumvent this restriction employing a method known as the "relay-attack".
To accomplish this, two people work in tandem one is positioned by the car, using the device that captures a digitized version of the key fob's signal. The other, standing by the house of the owner is using a different device to transmit the key fob's signal to the car. This trickery fools the car into thinking the key fob is close enough to unlock and begin the engine.
This kind of heist was once a costly process that required expensive equipment. It is now possible to purchase a cheap relay transmitter online and carry out an heist in just a few minutes. This is the reason why car thieves love it.
All modern vehicles with keyless access are vulnerable. Certain cars are more susceptible to this kind of attack than others. In fact researchers have examined 237 vehicles that are popular and found that they could be all stolen using this method.
Tesla vehicles are said to be less prone to this kind of theft. However, the company hasn't yet implemented UWB technology that would allow it to perform distance checks and prevent relay attacks. The company has promised to do so in the future, but for now they are still vulnerable. This is why it's crucial to be proactive about your vehicle security and install an anti-theft tool which protects your keys as well as your the car from such attacks.
CAN Injection Attack
Modern cars can protect themselves from theft by exchanging encrypted messages with the key to verify its authenticity. This method is generally thought to be secure, but thieves have found a way to circumvent it. They impersonate the smart key, then send messages to the vehicle and then drive off. To do this, they gain access to the smart keys' internal communications network.
Most cars today are equipped with between 20 and 200 electronic control units, or ECUs, that manage various aspects of the vehicle's operation. They communicate through an electronic network known as CAN bus. To ensure that power consumption is low the ECUs enter a low-power sleep mode that's 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. However the messages aren't usually encrypted or authenticated and, therefore, could be snatched by criminals using a cheap and basic device.
They search for a spot where they can connect directly to the wires for CAN connection. They usually hide in the headlights, or in other locations in the front of the vehicle. To access them, you must remove the bumper and cut holes in the headlamp assemblies. The thieves use a device known as an CAN injection attack to send fake messages that trick the car's safety systems to unlock and disable the engine immobilizer.
These devices can be bought on the Dark Web and work with the majority of major car manufacturers, including BMW and Cadillac, Chrysler, Fiat and Ford, Honda, Hyundai here and Jeep, Lexus and Nissan, Renault and Toyota, Volkswagen and Maserati. The researchers who discovered this CAN Injection attack are recommending that all car manufacturers fix it in their existing models, but the fact is that thieves will continue to take everything they can lay their hands on. The best thing we can do is to try and prevent this by putting in mechanical security measures like Discloks on all cars, and making sure that they're always parked in well-lit areas that are clearly visible to passers-by.
Blocking the Signal
In a variant of the relay attack, which employs a device that is able to block the signal from a key fob while the vehicle is locked. The device could be found inside the pocket of a burglar in a parking space or in a hidden spot close to the driveway that is being targeted. The owners don't know whether the vehicle is locked after pressing the lock button. Instead, thieves can escape with the vehicle since 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 do this when the key is in the pocket of the driver or hanging from its hook in the house. After the car is unlocked, hackers can make use of a standard diagnosis port to create a blank fob.
To safeguard against this kind of attack, car makers have come up with a range of anti-theft devices. However, thieves will always come up with new ways to beat these measures.
For instance, they've been using devices that transmit on the same radio frequency as remote key fobs to intercept their signals. The thieves can then copy the unlock code of the key fob and start the car with this fake signal.
This method is particularly popular in the US and Europe where a lot of automobiles are sold with wireless technology that allows owners to unlock and start their cars with a mobile app on their phone. This technology will likely increase in popularity as more companies attempt to connect their vehicles with their owners phones.
In addition to incorporating anti-theft technology in vehicles, it's vital for drivers to use the best practices when parking their cars. It is not a good idea to leave keys in the ignition. They should always make sure the car is securely locked when they're not in it and should use a steering wheel or gearstick lock, if it is possible. They should also think about installing a tracking device on their vehicle in the event it is stolen.
Flat Battery
This type of attack occurs more often than we think. Thieves use inexpensive devices to extend the signal from your key fob to unlock and start a car even when it's shut off. Then, they drive the car to the trailer or around a corner and take it away. It would be possible to protect your vehicle from this by installing a starter circuit interrupt switch. Simpler versions come with an ON/OFF button that interrupts the circuit. It's about $15 and is easy to install.
Car thieves are constantly seeking new ways to rob vehicles. The police as well as the car makers and insurance companies are always trying to keep up to their tactics and offer better anti-theft solutions for modern vehicles. But that doesn't stop the thieves who are able change quickly and find ways to get around the most up-to-date anti-theft systems.
For example, many criminals employ devices that operate on the same radio frequency as the fob to jam the signal. The device is tucked away in the pocket or close by the vehicle and prevents the fob from transmitting the lock command to the car. This can be done within minutes. The device is affordable and readily available on the internet.
Another option is to hack the car's computer system. This is harder but still possible. All cars have an diagnostic port and hackers have created devices that connect to them and let them access the software in the car. From there, they can program a blank key fob and make it work. This is also possible on older cars, although it is more difficult without removal of the ignition lock.
As more vehicles are linked to drivers' phones and this method could become more popular too. Once a thief gets the username and password for an app for vehicles and then they can unlock the car or start it by using the app on their phone. Fortunately, you can protect yourself from these types of attacks by not putting valuables in your car, and then parking it in a garage or secure parking lot.
