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 sophisticated method used by criminals to steal new keyless vehicles.
Keyless ignition vehicles emit a low power radio signal that is used to locate a matching fob. If the signal can be captured and recreated, it can be used unlock the car and to start it.
Relay Attack
Imagine your car parked in your driveway with your key fob inside your home. You might think that your vehicle is secure but sophisticated thieves are planning a heist, without you knowing. Instead of slamming windows or jiggling locks, they are using technology to gain access to cars through digital cracks in their armor. This is known as relay theft, it's a more common method of stealing vehicles that have keyless entry.
The keyless entry system found in cars is controlled by a signal sent by the car's RF transmitter to the key fob. To ensure that keyless entry is not accessed by unauthorized individuals the RF transmitters that are on the key fob and the car are programmed to be activated when they are within a certain distance from each other. However, thieves are able to bypass this limitation with a technique known as the'relay attack'.
To accomplish this, two people work in tandem one is positioned by the car with the device that captures an electronic version of the key fob's signal. The other, standing by the home of the owner, uses a second device to send the key fob signal back down to the car. This trickery fools the car into believing that the key fob has reached a distance sufficient to allow it to be opened and started the vehicle.
In the past, this type of attack required expensive equipment to carry out. However, now you can purchase a relay transmitter on the cheap online and execute a heist in minutes. This is the reason it's popular among car thieves.
While some cars are less susceptible to this type of theft than others, all modern cars that have keyless entry are at risk. Researchers have tested 237 popular cars and found that all of them could be taken by this method.
Tesla vehicles are believed to be less vulnerable to this kind of theft. However Tesla hasn't implemented UWB technologies that would allow it to perform distance checks and stop attacks via relay. The company has stated that they will implement this in the future but until then, they are vulnerable. Installing an anti-theft system that protects both your car keys and your keys against such attacks is a proactive method to ensure your car's security.
CAN Injection Attack
Modern vehicles are designed to guard themselves from thieves by transferring cryptographic messages using the key to prove that it's authentic. The system is thought to be secure, but criminals have found ways to circumvent it. They pretend to be the smart key, then send messages to the vehicle and then drive off. To do this, they gain access to the smart keys' internal communication network.
Nowadays, the majority of cars are equipped with between 20 and 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate using the CAN bus network. These ECUs enter 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 via the door or smart key receiver ECU. However they aren't always encrypted or authenticated so they can be intercepted by criminals using a cheap and basic device.
To do this, they look for a place where they can directly connect to the CAN bus wires. They usually are hidden in the headlights, or in other areas of the front of the vehicle. To get them, you need to pull the bumper and cut holes in the headlamp assemblies. The thieves use an instrument known as a CAN injection attack to send fake messages which can trick the security systems of the car into unlocking and disengaging the engine immobilizer.
These devices can be purchased on the Dark Web and work with most major car manufacturers which include 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 it in their existing models, but the reality is that thieves will continue to take anything they can get their hands on. The best thing we can do is to make an effort to prevent this from happening by putting in mechanical security measures like Discloks on all cars, 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 variant different to the relay attack, thieves may employ a device to block the signal from the key fob when the vehicle is locked. The device could be in the pocket or hidden the location of a thief in the parking lot, or near the driveway being targeted. Owners aren't able to verify if the car is locked after pressing the lock button. The device of the crook blocks the signal that locks the vehicle. Thus, thieves are able to leave the vehicle.
The crooks also employ devices to amplify the key fob's signals in order to unlock vehicles. The crooks can accomplish this even if the key is in the pocket of a driver, or hanging on a hook inside the home. After the car has been locked, they can use a standard diagnostic port or computer hackers to program the blank key fob and gain control of the vehicle.
To safeguard against this kind of attack, car manufacturers have created a variety of anti-theft gadgets. However, thieves will always come up with ways to thwart these measures.
For instance, they've been using devices that transmit on the same frequency as remote key fobs to intercept their signals. The crooks then copy the unlock code from the key fob and start the vehicle using this fake signal.
This method is very popular in the US and Europe where many automobiles are sold with wireless technology that allows owners to unlock and start their vehicles using a mobile app on their phone. This technology is expected to become increasingly popular as more and more companies attempt to connect their vehicles with their owner's smartphones.
In addition to incorporating anti-theft technology in vehicles, it's crucial for drivers to use the read more best practices when they park their vehicles. It is not advisable to leave the key fobs in ignition and should always lock the car when not in it. If they can, they should also use a steering or gearstick locking device. It is also recommended to consider installing a tracking device to their car in case it is stolen.
Flat Battery
This type of attack occurs more often than we think. The thieves employ low-cost devices that increase the signal from your key fob in order to unlock and start your car even in the event that it is off. Then they drive the vehicle to a trailer or around a corner, and take it away. It would be possible to protect your car from this by installing a starter circuit interrupt switch. The most basic ones have an ON/OFF switch that shuts off the starter circuit. It's priced at around $15 and is simple to install yourself.
Car thieves are always looking for new ways to gain access to vehicles and take them away. The police as well as car manufacturers and insurance companies are always trying to keep up with their strategies and offer better anti-theft solutions for the latest cars. But that doesn't stop the thieves who are able change quickly and discover ways to bypass 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 blocks the fob from sending the lock command to the vehicle. This can be accomplished in a matter of minutes. The device is affordable and available online.
Hacking the computer system of the car is another option. This is more difficult but nevertheless possible. All cars have an diagnostic port and hackers have designed devices that plug into them and allow them access the software of the car. From there, they are able to program the blank key fob to start working. This can also be done on older vehicles, however it is more difficult to do without taking off the ignition lock.
This technique could become more popular if more vehicles are connected to drivers' mobile phones. Once a criminal has the username and password for the vehicle app and then they can unlock the car or start it with the app on their phone. You can guard yourself by not leaving valuables in your car and by parking in garages.
