Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or near their doors, they may unknowingly allow thieves to hijack their signal. This relay attack is a high-tech method used by criminals to steal keys from new vehicles.
All keyless ignition cars emit an low-power radio signal that is seeking a compatible fob that can respond. If the signal is recorded and recreated, it could be used to unlock the car and then start it up.
Relay Attack
Imagine your car at your driveway, with your key fob in your home. You're confident that your vehicle is safe, but not seen by you sophisticated thieves are planning an attack. Instead of slamming windows and jiggling locks, they are using technology to hack into vehicles using digital cracks in their armor. This method of stealing cars with keys is known as relay theft.
The keyless entry system that is 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 unauthorized the RF transmitters on the key fob and in the car are programmed to activate only when they're within a certain distance of each other. However, thieves can bypass this limitation with a technique called the 'relay attack'.
Two people are required to do this: one stands close to the car and utilizes a device to capture a digitalized version of the signal coming from the key fob. The other, who is at the house of the owner is using a different device to send the key fob's signal down to the car. This trickery tricks the car into believing that the key fob has traveled the distance needed 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 buy relay transmitters for low cost online and conduct an heist in a matter of minutes. This is why it's well-liked by car thieves.
All modern cars with keys are at risk. Certain cars are more susceptible to this kind of attack than others. In fact, researchers have tested 237 popular cars and found that they could be targeted by this method.
Tesla cars are said to be less vulnerable to this type of theft, but the company has not yet implemented UWB features that could effectively check distances on the car's signal and prevent relay attacks. The company has stated that they will make this happen in the near future, but for now, they remain vulnerable. That is why it's important to take a proactive approach to your security in your car and install an anti-theft device which protects your keys as well as your the car from such attacks.
CAN Injection Attack
Modern vehicles are designed to shield themselves from theft by exchanging cryptographic data with the key to prove it's genuine. The system is considered to be secure, but thieves have found ways around it. They just pretend to be the smart key and send other messages to the car, letting it unlock the doors, turn off its engine immobilizer, and then go on their way. To achieve this, they need access to the smart keys' internal communications network.
The majority of cars today are fitted 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 one another using the CAN bus. To keep power consumption low the ECUs are put into the sleep mode at low power. This mode is activated when they receive a wake up' frame. These frames are usually sent from the door or smart key receiver ECU. These messages are not always encrypted or authenticated. This means that criminals are able to capture them using an inexpensive and simple device.
To do this, they look for a location that allows them to connect directly to the CAN bus connection wires. They are usually hidden in the headlights or in other places in the front of the vehicle. To access them, you must remove the bumper and cut holes in the headlamp assemblies. The thieves use the device referred to as an CAN injection attack. It is used to send out fake messages that fool the safety systems of the car into unlocking and disengaging the engine immobilizer.
These devices are available for sale on the Dark Web, and work for the majority of major car manufacturers which include BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and more. 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 the thieves will continue to grab anything they can get their hands on. The best we can do is attempt to stop this from happening by installing security measures that are mechanical like Discloks on cars and ensuring that they're always located in areas with adequate lighting that are clearly visible to passers-by.
The Signal is blocked
In a different variation of the relay attack, thieves may make use of a device to block the signal from an electronic key fob if the vehicle is locked. The device could be in the pocket or in the hiding place of a thief on an open parking lot or near the driveway that is being targeted. The owners don't know whether their vehicle is locked when they press the lock button. The device used by the criminal block the signal that locks the vehicle. Therefore, thieves could leave the vehicle.
The crooks also use devices to amplify the signal from the key fob in order to unlock vehicles. The crooks can do this even when the key is in a driver's pocket, or hanging from an outside hook in the home. When the car is locked, they can use a standard computer hacker to program the 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 devices. But, thieves are constantly looking for ways to defeat these measures.
For example, they've started using devices that transmit on the same radio frequency as remote key fobs to intercept their signals. The crooks then copy the unlock code of the key fob and then start the car with this fake signal.
This technique is particularly popular in the US where a lot of cars come with wireless technology. Owners can unlock and start their vehicle by using a mobile app on their phone. This technology is expected to become increasingly popular as more and more companies try to connect their vehicles with their owner's smartphones.
It is important that drivers use best practices when parking their vehicles. It is not a good idea to leave key fobs in the ignition, and should always ensure that the car is fully locked when they're not using it and should use the steering wheel or a gearstick lock, if they can. They should also think about installing a tracking device on their vehicle in case it is stolen.
Flat Battery
This kind of attack occurs more often than people realize. Thieves employ cheap devices to extend the signal from your key fob to open and start a car even when it's turned off. They then drive the car around a corner or to a trailer and leave with it. Installing an interruption switch to the starter circuit will protect your vehicle from this. Simpler versions come with an ON/OFF button that shuts off the circuit. It costs about $15 and is simple to put in yourself.
Car thieves are always looking for new ways to enter vehicles and steal them. Car manufacturers, police and insurance companies are constantly trying to keep up with the latest tactics and provide more effective anti-theft systems for modern vehicles. But this isn't stopping thieves who easily adapt and find ways to circumvent the latest anti theft measures.
For instance, many criminals use devices that operate on the same frequency as the fob to jam the signal. The device is tucked away in the pocket or close by the vehicle read more and blocks the fob from transmitting the signal to the car. This can be accomplished in just a few seconds. The device is affordable and easily accessible on the internet.
Another strategy is to hack into the car's computer system. This is more difficult but nevertheless possible. Hackers have developed devices that plug into the diagnostic port of all vehicles and allow them to connect to the software. From there, they are able to program an unfinished key fob and start working. It is also possible to do this on older vehicles, but it is more difficult to do without removing the ignition lock.
As more vehicles are connected to the phones of drivers the method is likely to be more popular. Once a thief gets the username and password for the vehicle app, they can then unlock or start the car using the app on their phone. You can safeguard yourself by not putting valuables in your car and also by parking in a garage.
