Cars Being Stolen With Keyless Entry
Car owners who toss their keys on tables or near their front door could be giving thieves the ability to take over the signal. This relay attack is just one of the advanced methods criminals are using to steal brand new keys from cars.
Keyless ignition cars emit an extremely low-power radio signal, in search of a fob that can respond. If the signal is captured and recreated it can be used to unlock the car and then start it up.
Relay Attack
Picture your car parked securely in the driveway, and the key fob tucked away in your home. You're confident that your car is secure, but unseen by you sophisticated thieves are planning an attack. They use technology to hack into vehicles via digital chinks. Also known as relay theft, it's becoming a common method of stealing vehicles that have keyless entry.
The keyless entry system in cars is controlled by a signal by the car's RF transmitter to the key fob. To ensure that keyless entry is not unauthorized the RF transmitters on the key fob and car are programmed to only activate when they're within a specific distance from each other. However, thieves can bypass this limitation with an attack known as the'relay attack'.
Two individuals are required to perform this: one person stands near the car and uses a device that captures digitally the signal from the key fob. The other, who is at the home of the owner and using a second device to send the key fob signal back to the car. This trick tricks the car into thinking the key fob is near enough to unlock and start the engine.
In the past, this type of attack required expensive equipment to perform. It is now possible to purchase a relay transmitter for a small price online and pull off an heist in just a few minutes. This is why it's popular among car thieves.
While certain cars are less prone to this type of theft than others, all modern vehicles that have keyless entry are at risk. Researchers have examined 237 well-known cars and found that all of them are susceptible to being stolen through this method.
Tesla vehicles are said to be less prone to this kind of theft. However, the company hasn't yet implemented UWB technologies that would enable it to perform distance checks and prevent attacks via relay. The company has said it will do so in the future, but until then, they remain vulnerable. Installing an anti-theft system that protects both your keys and your car against such attacks is a proactive approach to ensure the security of your vehicle.
CAN Injection Attack
Modern cars can protect themselves against thieves by sending encrypted messages to the key to prove its authenticity. This method is generally thought to be secure, but thieves have found a way around it. They fake the identity of a smart key, transmit messages to the vehicle, and then drive away. To do this, they gain access to the smart keys' internal communication network.
Today, most cars are equipped 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 each other via a network known as CAN bus. To reduce power consumption they ECUs are put into sleep mode with low power that is activated when they receive a 'wake up' frame. These frames are typically sent from the door or smart key receiver ECU. However, these messages aren't always encrypted or authenticated and, therefore, can be intercepted by criminals using a cheap and simple device.
To do this, they look for a place that allows them to connect directly to the CAN bus wires. They are usually hidden within 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 the wires. The thieves employ an instrument known as a CAN injection attack to send fake messages which fool the safety systems of the car to unlock and disable the engine immobilizer.
The devices are available for purchase 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 many more. The researchers who discovered this CAN Injection attack are recommending that all car manufacturers fix it in their existing models, but the reality is that the thieves will continue to steal anything they can get their hands on. The best we can do is to try and prevent this by installing mechanical security measures like Discloks on our cars and ensuring that they are located in areas with adequate lighting that are clearly visible to passers-by.
Blocking the Signal
In a variant of the relay attack, which makes use of a device that is able to block the signal from key fobs while the car is locked. The device may be inside the pocket of a thief in a parking area or in a hiding spot near the driveway that is being targeted. Owners don't check whether their car is locked check here after pressing the lock button. Instead, thieves could escape with the vehicle because the signal that normally locks the car is blocked by the crook's device.
The crooks also use devices to amplify the key fob's signals to unlock vehicles. The crooks can do this even when the key is inside a driver's pocket or hanging from a hook inside the home. Once the car has been unlocked, hackers can use the standard diagnostic port to program an unlocked fob.
Automobile manufacturers have come up with a variety of anti-theft solutions to protect against these types of attacks. But, as always, thieves come up with new ways to beat these measures.
They've been using devices that transmit at the same frequency as remote keyfobs to intercept signals. The thieves can then copy the key fob's unlock code and start the car with this fake signal.
This method is especially 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 from their mobile. This technology will likely become more popular as more manufacturers try to connect their cars to their owners' smartphones.
In addition to implementing anti-theft systems in vehicles, it's vital for drivers to leverage best practices when parking their vehicles. They should never leave the key fobs in ignition and always secure the car when not in it. If they can it is also recommended to use the gearstick or steering locking device. They should also consider installing a tracking device on their vehicle in the event that it is stolen.
Flat Battery
This kind of attack is more common than people think. The thieves make use of inexpensive devices that extend 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, and take the car away. It is possible to protect your car from this by installing an interrupter switch for the starter circuit. Simpler versions include an ON/OFF button which interrupts the circuit. It costs around $15 and is easy to install.
Car thieves are always working on new ways to gain access to vehicles and then steal them. The police, car makers and insurance companies are constantly trying to keep up with their strategies and offer better anti-theft solutions for modern cars. But that doesn't stop the thieves, who are able to adapt quickly and find ways to get around the most up-to-date anti-theft systems.
For instance, a lot of thieves use devices that operate on the same frequency as the fob in order to block the signal. The device is put in the pocket or close by the vehicle, and stops the fob from sending the lock command to the car. This can be done in just a few seconds. The device is cheap and readily available on the internet.
Hacking the computer system of the car is another option. This is harder but still possible. All cars have an diagnostic port, and hackers have designed devices that plug into them and let them access the car's software. From there, they can program the blank key fob to get it to work. This is also possible on older vehicles, but it is more difficult to do without taking off the ignition lock.
This method is likely to be more popular if more vehicles are connected with drivers' phones. Once a burglar has gained the username and password for an app for vehicles they are able to unlock or start the car with the app on their phone. You can safeguard yourself by not leaving valuables inside your car, and also by parking in a garage.
