Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or at their doors, they could not realize that they are allowing thieves to hijack their signal. This relay attack is a highly-tech method criminals use to steal keys from new vehicles.
All keyless ignition cars emit a low-power radio signal in search of a fob that can respond. If the signal can be captured and recreated, it can be used to unlock the car and start it.
Relay Attack
Imagine your car being parked safely in the driveway, and the key fob tucked away inside your home. You're confident that your car is secure, but unseen by you sophisticated thieves are planning an heist. The thieves employ technology to snoop on vehicles through digital chinks. This method of stealing vehicles with keyless access is known as relay theft.
The keyless entry system found in cars is controlled by a signal by the car's radio transmitter to the key fob. To ensure that keyless entry is not accessed by intruders, the RF transmitters on the key fob as well as the car are programmed only to be activated when they are within a specified distance of each other. However, thieves can override this restriction using a technique called the 'relay attack'.
To accomplish this, two people work together One stands near the car with an instrument that records an electronic version of the key fob's signal. The other who is at home with the owner is using a second device to transmit the signal from the key fob to the car. This trickery tricks the car into believing that the key fob has traveled an adequate distance to unlock and start the vehicle.
This type of heist was once a costly process that required expensive equipment. Now, you can pick up relay transmitters for low cost online and conduct the heist in just a few minutes. This is why it's well-liked by car thieves.
While certain vehicles are less susceptible to this type of theft than others, all cars that have keyless entry are vulnerable. In fact researchers have examined 237 popular cars and found that they can all be stolen using this method.
Tesla vehicles are believed to be less vulnerable to this kind of theft. However Tesla hasn't yet implemented UWB technology to enable it to perform distance checks and prevent relay attacks. The company has stated that they will implement this feature in the near future, but for now they are vulnerable. Installing an anti-theft device that protects both your keys and your car against such a threat is a proactive way to ensure the security of your vehicle.
CAN Injection Attack
Modern vehicles are designed to guard themselves from thieves by exchanging cryptographic data with the key to prove that it's genuine. This method is generally thought to be secure, but criminals have found a way around it. They impersonate the smart key, then send messages to the vehicle, and then drive away. To do that they gain access to the smart key's internal communications network.
Nowadays, the majority of cars are fitted with between 20 to 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate using a network called CAN bus. To reduce power consumption the ECUs are put into sleep mode with low power that is activated when they receive a wake up frame. These frames are usually sent by the ECU that manages the smart key or door. These messages aren't always encrypted or authenticated. This means that criminals can take them over with a simple and cheap device.
They search for a location that allows them to connect directly to the wires for CAN connection. They usually hide in the headlights, or in other areas of the front of the vehicle. To gain access to them, you must here remove the bumper and cut holes in the headlamp assemblies. The thieves use an instrument known as an CAN injection attack. It is used to send fake messages that trick the car's safety systems into unlocking and disengaging the 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. 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 these thieves will continue to take everything they can lay their hands on. We can stop this from happening by installing mechanical security measures such as Discloks in all of our cars and parking them in well-lit and visible areas.
Jamming the Signal
In a variant of the relay attack, which uses a gadget that can be used to block the signal transmitted by key fobs while the vehicle is locked. The device could be found in the pocket or hidden the location of a thief in a parking lot, or in the driveway that is being targeted. Once the owners hit the lock button on their fobs and walk away they don't consider whether or not their car is actually locks. The device used by the crook block the signal that locks the car. Therefore, thieves could drive away with the vehicle.
They also have devices that amplify signals from the key fob to unlock vehicles. The crooks are able to do this even if the key is in the driver's pocket or hanging from a hook inside the home. Once the car has been unlocked, hackers can make use of an ordinary diagnosis port to create an unlocked fob.
Car manufacturers have developed a variety of anti-theft solutions to protect against these types of attacks. But, as always, thieves find ways to defeat these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The thieves then copy the unlock code from the key fob and start the vehicle with this fake signal.
This method is particularly popular in the US, where many cars have wireless technology. Owners can start and unlock their car using a mobile application on their phone. This technology will likely increase in popularity as more companies attempt to link their cars with their owners smartphones.
It is crucial that drivers use best practices to park their vehicles. They shouldn't leave their key fobs in the ignition, should always ensure that the car is fully locked when they're not there and should utilize an engine or steering wheel lock, if they can. They should also consider having a tracking device fitted to their car in the event it's stolen.
Flat Battery
This kind of attack happens more often than people realize. Thieves make use of cheap devices to extend the signal from your key fob to open and start the car, even if it's turned off. Then they drive the car to the trailer or around a corner and take it away. Installing an interruption switch to the starter circuit will protect your vehicle from this. Simpler versions come with an ON/OFF button which interrupts the circuit. It costs around $15 and is simple to install.
Car thieves are always seeking new ways to rob vehicles. The police as well as the car makers and insurance companies are always trying to keep up with their strategies and offer better anti-theft solutions for modern cars. But this doesn't stop thieves who can easily adapt and find ways to circumvent the latest anti theft measures.
A lot of thieves block the signal with devices that use the same radio frequency as the fob. The device is put in the pocket or close to the vehicle, and stops the fob from sending the lock command to the vehicle. This can be done in seconds. The device is cheap and easily accessible on the internet.
Another option is to hack the car's computer system. This is more difficult, but possible. Hackers have developed devices that connect to the diagnostic port of all vehicles and allow them to connect to the software. From there, they can program the blank key fob to start working. It is possible to do this on older vehicles too, but it's more difficult without taking out the ignition.
This method is likely to be more popular if more vehicles are connected to drivers' phones. Once a burglar has gained the username and password to the vehicle app they are able to unlock the car or start it by using the app on their phone. Fortunately, you can be safe from these kinds of attacks by not putting valuables in your car and putting it in a garage or secure parking lot.
