Cars Being Stolen With Keyless Entry
If car owners leave their keys on the table or at their doors, they may unknowingly be allowing thieves to hijack their signal. This relay attack is a high-tech method criminals use to steal new keyless vehicles.
All keyless ignition cars emit a low-power radio signal seeking a compatible fob to respond. If the signal can be captured and recreated, it can be used unlock the car and to start it.
Relay Attack
Picture your car parked securely in your driveway, with the key fob tucked away in your home. You're sure that your car is safe, but not seen by you sophisticated thieves are planning a heist. They use technology to hack into vehicles using digital chinks. Also known as relay theft, it's becoming a popular method of stealing cars with keyless entry.
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 unauthorized the RF transmitters inside the key fob and in the car are programmed to only be activated when they're within certain distance from each other. However, a thief can bypass this limitation with a technique known as the'relay attack'.
To do so, two people work together: one stands by the car with a device that captures a digitized 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 back to the car. This trickery tricks the car into believing that the key fob is at a distance sufficient to allow the vehicle to start and unlock. vehicle.
In the past, this type of attack required expensive equipment to perform. You can now buy a cheap relay transmitter online and carry out an heist in just a few minutes. This is the reason it's well-liked by car thieves.
All modern cars with keys are at risk. Certain vehicles are more susceptible to this type of attack than others. In fact researchers have examined 237 popular cars and found that they could be targeted by this method.
Tesla vehicles are believed to be less susceptible to this kind of theft. However, the company hasn't yet implemented UWB technologies that would allow it to perform distance checks and prevent relay attacks. The company has said that they will do this in the near future, but until then, they are vulnerable. Installing an anti-theft system that protects both your car and your keys against these types of attacks is a proactive method to ensure the security of your car.
CAN Injection Attack
Modern cars can guard themselves from thieves by transferring encrypted messages using the key in order to confirm its authenticity. The system is considered to be secure, but thieves have found ways to get around it. They simply impersonate the smart key and send messages to the vehicle letting it unlock the doors, turn off its engine immobilizer, and let them leave the car. To do that they gain access to the smart key's internal communication network.
These days, most automobiles are equipped with between 20 to 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate through an electronic network known as CAN bus. To ensure that power consumption is low the ECUs are put into a low-power sleep mode that's activated when they receive a wake up' frame. These frames are usually sent by the ECU that controls the smart key or door. However they aren't always authenticated or encrypted and, therefore, could be snatched by criminals using a cheap and simple device.
To accomplish this, they search for a spot that allows them to connect directly to the CAN bus wires. They are usually hidden in the headlights or in front of the car, and are accessible by pulling the bumper off and cutting holes in the headlamp assembly to expose them. The thieves then use a device called an CAN injection attacker, which is used to send fake messages which trick the car's security systems into unlocking the car and disengaging the engine immobilizer.
These devices are available for purchase on the Dark Web, and work for all major car manufacturers including 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 makers fix the issue in their current models, but the reality is that these thieves will continue to steal everything they can lay their hands on. The best we can do is try and prevent this by installing mechanical security measures like Discloks on our vehicles, and making sure that they're always placed in areas that are well-lit and are easily visible to pedestrians.
Blocking the Signal
In a variation of the relay attack, which makes use of a device that can be used to block the signal transmitted by a key fob while the vehicle is locked. The device could be hidden in the pocket or hiding the location of a thief in the parking lot, or even near the driveway being targeted. Owners don't check whether their car is locked after pressing the lock button. The device used by the criminal interferes with the signal to lock the car. Therefore, thieves could drive away with the vehicle.
The crooks also use devices to amplify the key fob's signals to unlock vehicles. They may even accomplish this if the key is in the driver's pocket or hanging from a hook in the home. After the car is unlocked, hackers can use a standard diagnosis port to program an unlocked fob.
To guard against this kind of attack, car makers have come up with a range of anti-theft devices. But, as always, thieves find 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 crooks then copy the key fob's unlock code and start the car with this fake signal.
This method is very popular here in the US and Europe where many vehicles are sold with wireless technology that lets owners unlock and start their vehicle with a mobile app on their phone. This technique is likely to be more commonplace as more car manufacturers attempt to connect their vehicles with their owners smartphones.
It is crucial that drivers follow the right procedures to park their cars. They should not leave their keys in the ignition and always secure the car when not in it. If possible they should also utilize a steering or gearstick locking device. They should also consider installing a tracking device onto their vehicle in case it is stolen.
Flat Battery
This kind of attack is more prevalent than most people realize. Thieves make use of inexpensive devices to extend the signal from your key fob to unlock and begin the car, even if it's turned off. Then they drive the vehicle to the trailer or around a corner and take it away. Installing a starter circuit interruption switch can protect your vehicle from this. Simpler versions have an ON/OFF button that shuts off the circuit. It costs about $15 and is simple to put in yourself.
Car thieves are always working on new ways to get into vehicles and steal them. Police, car manufacturers and insurance companies are constantly trying to stay abreast of the latest tactics and provide better anti-theft systems for modern vehicles. But that doesn't stop thieves who are able to change quickly and find ways to get around the latest anti-theft measures.
For instance, a lot of criminals employ devices that operate on the same frequency as the fob to jam the signal. The device is placed in the pocket or close to the vehicle, and stops the fob from transmitting the lock command to the vehicle. This can be accomplished in just a few seconds. The device is cheap and easily accessible on the internet.
Another strategy is to hack into the car's computer system. This is more difficult, but still feasible. Hackers have developed devices that connect to the diagnostic port of all vehicles and allow them to access the software. They can then program the fob with blank code to work. This is also possible on older vehicles, but it is more difficult to do so without taking off the ignition lock.
This method is likely to be more popular if more vehicles are connected with drivers' mobile phones. Once a thief has access to the username and password to a vehicle application and is able to unlock or start the vehicle with the app. You can protect yourself by not putting valuables inside your car, and parking in a garage.
