Cars Being Stolen With Keyless Entry
If car owners throw their keys on the table or next to their doors, they could not realize that they are allowing thieves to hijack their signal. This relay attack is a high-tech technique used by criminals to steal new keyless vehicles.
Keyless ignition cars emit an low-power radio signal that is looking for a matching fob that can respond. If the signal is recorded and recreated, it could be used to unlock the car and begin it up.
Relay Attack
Picture your car parked securely in the driveway, with the key fob sitting safely inside your home. You're confident that your vehicle is safe, but not seen by you sophisticated thieves are planning a heist. They use technology to hack into vehicles via digital chinks. This method of stealing vehicles with keyless access is called relay theft.
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 unauthorized keyless entry the RF transmitters on the key fob and car are programmed to activate only when they're within a specific distance from one another. However, thieves are able to overcome this limitation using an attack known as the'relay attack'.
Two people are required to complete this: one person 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 home of the owner, uses a second gadget to transmit the signal from the key fob back to the car. This trick tricks the car into believing the key fob is at a distance sufficient to unlock and start the vehicle.
This kind of heist used to require expensive equipment. Today, you can purchase an inexpensive relay transmitter on the internet and complete an heist in just a few minutes. This is why it's popular among car thieves.
All modern cars with keys are at risk. Certain vehicles are more susceptible to this type than others. In fact researchers have examined 237 vehicles that are popular and found that they could be targeted by this method.
Tesla cars are said to be less susceptible to this type of theft, but the company hasn't yet implemented UWB features to effectively check distances on the car's signal and stop relay attacks. The company has stated that they will implement this feature in the near future, but for now, they remain vulnerable. Installing an anti-theft system that guards your car keys and your keys against these types of attacks is a proactive way to ensure the security of your car.
CAN Injection Attack
Modern vehicles are designed to guard themselves from thieves by transferring cryptographic messages using the key to prove it's genuine. The system is generally believed to be secure, but criminals have found a way to circumvent 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 go on their way. To do this they gain access to the smart key's internal communications network.
These days, most cars are equipped with between 20 to 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate via an electronic network known as CAN bus. These ECUs are put into a low power sleep mode to decrease their power consumption. This mode is activated when the ECUs receive a "wake up" frame. These frames are typically sent from the door or smart key receiver ECU. However they aren't always encrypted or authenticated and, therefore, can be intercepted by criminals who have a low-cost and simple device.
To do this, they look for a location where they can directly connect to the CAN bus wires. These are often hidden away within the headlights or in front of the vehicle, and are accessible by pulling the bumper off and cutting holes in the headlamp assembly to expose them. The website thieves then employ a device dubbed an CAN injection attacker to send fake messages that trick the car's security systems into unlocking it and disengaging the engine immobilizer.
These devices can be purchased on the Dark Web and work with all major car makers, 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 address this issue in their existing models. However, these criminals will continue to steal whatever they can. The best we can do is try and prevent this by putting in mechanical security measures such as Discloks on all of our vehicles and ensuring that they are always placed in areas that are well-lit and are clearly visible to people passing by.
The Signal is blocked
In a variant of the relay attack that makes use of a device that is able to block the signal transmitted by key fobs while the vehicle is locked. The device could be in the pocket or hidden the location of a thief in the parking lot, or in the driveway being targeted. Once owners press the lock button on their fobs and leave, they don't think about whether or not their car is really locked. Instead, thieves could escape with the vehicle since the signal that normally locks the car is blocked by the crook's device.
The crooks also use devices to amplify the signal from the key fob in order to unlock vehicles. The crooks can accomplish this even if the key is inside a driver's pocket, or hanging from a hook inside the home. After the car has been unlocked, they can make use of the standard diagnostic port or computer hackers to program an unlocked key fob to gain control of the vehicle.
To safeguard against this kind of attack, car manufacturers have come up with a range of anti-theft gadgets. However, thieves will always come up with ways to thwart 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 thieves copy the unlock code of the key fob and start the vehicle with this fake signal.
This technique is especially popular in the US and Europe where a large number of cars are sold with wireless technology that lets owners unlock and start their cars using a mobile app on their smartphone. This technology will likely increase in popularity as more manufacturers try to link their cars with their owners' smartphones.
It is essential that drivers follow the right procedures to park their vehicles. They should never leave their keys in the ignition, and should always ensure that their car is fully locked when they're not in it and should use the steering wheel or a gearstick lock, if it is possible. It is also recommended to consider installing a tracking device to their car in the event it gets stolen.
Flat Battery
This type of attack is more common than people think. The thieves employ low-cost devices that increase the signal from your key fob to enable it to unlock and start your car even if it is off. They then drive the car around the corner or even to a trailer and then drive off with it. It would be possible to shield your vehicle from this by installing an interrupter for the starter circuit. Simpler versions come with an ON/OFF button that interrupts the circuit. It is priced at around $15 and is simple to install.
Car thieves are always trying new ways to get into vehicles and then steal them. Car manufacturers, police and insurance companies are always 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 adapt quickly and discover ways to bypass the most up-to-date anti-theft systems.
Many thieves block the signal with a device that uses the same radio frequency as the fob. The device is tucked away in the pocket or close to the vehicle and blocks the fob from sending the signal to the car. This can be done in just a few seconds. The device is inexpensive and easily available online.
Hacking the computer system of the car is an alternative option. This is more difficult but still possible. Hackers have developed devices that connect to the diagnostic port of all vehicles and allow them to connect to the software. They can then program a blank fob to function. It is also possible to do this on older vehicles, however it is more difficult to do without taking off the ignition lock.
As more vehicles are linked to smartphones of drivers, this method may become more popular as well. Once a burglar has access to the username and password to an application for vehicles and is able to unlock or start the vehicle using the app. It is possible to defend yourself from these kinds of attacks by not putting valuables in your car, and then parking it in a secure garage or parking lot.
