Cars Being Stolen With Keyless Entry
Car owners who throw keys on tables or near their front door may be unwittingly 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 cars emit a low-power radio signal looking for a matching fob that can respond. If the signal can be captured and recreated, it could be used to unlock the car, and also to start it.
Relay Attack
Imagine your car in your driveway, and your key fob in your home. You might think that your car is secure, but sophisticated thieves are planning to steal your car without you even knowing. Instead of slamming windows and jiggling locks, these thieves are using technology to gain access to cars through digital cracks in their armor. This is known as relay theft, it's a more popular method of stealing cars with keyless entry.
The keyless entry system that is found in cars is controlled by a signal by the car's radio transmitter to the key fob. To stop keyless entry by intruders the RF transmitters that are on the key fob as well as the car are programmed only to turn on when they are within a specified distance of each other. However, thieves is able to circumvent this restriction using a technique known as the'relay-attack'.
Two individuals are required to perform this: one person stands close to the car and uses a device that captures an electronic version of the signal from the key fob. The other, standing by the owner's house is using a different device to transmit the key fob's signal down to the car. This trick tricks the car into thinking the key fob is close enough to be able to unlock it and begin the engine.
In the past, this kind of heist required expensive equipment to perform. However, now you can buy relay transmitters for low cost online and conduct an heist in a matter of minutes. This is why it's popular with car thieves.
While certain cars are less vulnerable to this kind of theft than others, all modern vehicles with keyless entry are vulnerable. In fact, researchers have tested 237 popular vehicles and found that they can be targeted by this method.
Tesla vehicles are supposedly less susceptible to this type of theft, however the company hasn't yet implemented UWB features that could effectively conduct distance checks on the car's signal and prevent relay attacks. The company has said that they'll implement this in the near future, but until then, they're vulnerable. That's why it's essential to adopt a proactive approach to your car security and install an anti-theft tool that protects your keys and the car from such attacks.
CAN Injection Attack
Modern vehicles are designed to protect themselves from theft by exchanging cryptographic messages with the key to prove it's authentic. The system is thought to be secure, but thieves have found ways to get around it. They just impersonate the smart key, and send other messages to the car letting it unlock the doors, disable its engine immobilizer, then let them leave the car. To do that they have access to the smart key's internal communication network.
Today, most cars are fitted with between 20 to 200 electronic control units (or ECUs) that manage different aspects of the car's operation. They communicate via the CAN bus network. These ECUs are put into a low power sleep mode to decrease their power consumption. This mode is activated when ECUs receive an "wake up" frame. These frames are usually sent by the ECU that is in charge of the smart key or door. However they aren't always authenticated or encrypted and, therefore, can be intercepted by criminals who have a low-cost and simple device.
To accomplish this, they search for a spot website that allows them to connect directly to the CAN bus connection wires. These are often hidden away inside the headlights or elsewhere in front of the vehicle, and are accessible by removing the bumper and cutting holes in the headlamp assembly to expose them. The criminals then employ a device dubbed a CAN injection attacker to send out fake messages that trick the car's security systems to unlock it and disable its engine immobilizer.
These devices can be purchased on the Dark Web and work with most major car manufacturers, including 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 makers fix this issue in their existing models. However, the thieves will continue to take whatever they can. The best thing we can do is try and prevent this by putting in mechanical security measures like Discloks on all our vehicles, and making sure that they are located in areas with adequate lighting that are easily visible to pedestrians.
Blocking the Signal
In a variant different to the relay attack, thieves may employ a device to block the signal sent from a key fob when the vehicle is locked. The device may be hidden in the pocket of a burglar in a parking lot or in a hidden spot close to the driveway that is being targeted. Owners aren't able to verify whether their vehicle is locked after pressing the lock button. The device used by the criminal interferes with the signal to lock the vehicle. Thus, thieves are able to escape with the car.
The crooks also use devices to amplify the signal from the key fob to unlock vehicles. They may even accomplish this if the key is in the driver's pocket or hanging from its hook inside the house. After the car has been unlocked, they can make use of the standard diagnostic port or computer hackers to program a blank key fob and gain control of the vehicle.
To guard against this kind of attack, car manufacturers have developed a variety of anti-theft gadgets. However, criminals are constantly looking for ways to defeat these measures.
They've been using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The thieves then copy the unlock code of the key fob and start the vehicle using this fake signal.
This technique is especially popular in the US and Europe where a lot of cars are equipped with wireless technology that lets owners unlock and start their vehicles by using a mobile application from their phones. This technique is likely to be more commonplace as more manufacturers try to link their cars with their owners phones.
In addition to installing anti-theft technologies in vehicles, it's vital for drivers to follow the best practices when they park their vehicles. It is not a good idea to leave key fobs in the ignition, should always ensure that their vehicle is locked completely when they're not there and should make use of an engine or steering wheel lock, if they can. They should also think about installing a tracking device to their car in the event it's stolen.
Flat Battery
This kind of attack occurs more often than most people realize. The thieves make use of cheap devices that extend the signal from your key fob to enable it to unlock and start your car even when it's off. They then simply drive the car around the corner or even to a trailer and take off with it. Installing an interruption switch to the starter circuit can protect your vehicle from this. The most basic ones have an ON/OFF switch which interrupts the starter circuit. It costs about $15 and is easy enough to install yourself.
Car thieves are always working on new ways to get into vehicles and take them away. The police as well as the car makers and insurance companies are always trying to catch up with their strategies and offer better anti-theft solutions for the latest cars. However, that doesn't stop thieves who are able to change quickly and find ways to circumvent the most recent anti-theft measures.
A lot of thieves block the signal using devices that operate on the same radio frequency as the fob. They place the device in their pockets or near their vehicle, and it prevents the fob's lock command from reaching the vehicle, leaving it unlocked. This can be done in seconds. The device is affordable and readily available on the internet.
Hacking the computer system of the car is another option. This is more difficult but nevertheless possible. Hackers have designed devices that plug into the diagnostic port of all vehicles and allow them to access the software. From there, they can program an unfinished key fob and make it work. It is also possible to do this on older cars, although it is more difficult to do without taking off the ignition lock.
This method could become more popular as more vehicles are connected with drivers' phones. Once a criminal has the username and password to an application for vehicles, they can unlock or start the vehicle with the application. 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.
