Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or next to their doors, they may unknowingly allow thieves to hijack their signal. This relay attack is a highly-tech technique used by criminals to steal keyless vehicles.
All keyless ignition cars emit an low-power radio signal that is in search of a fob to respond. If the signal is recorded and recreated, it could be used to unlock the car and start it up.
Relay Attack
Imagine your car being parked safely in your driveway, with the key fob tucked away inside your home. You might think that your car is safe but sophisticated thieves are planning to steal your car without you even knowing. They use technology to hack into vehicles using digital chinks. Known as relay theft, it's an increasingly common way to steal cars that have keyless entry.
Cars with keyless entry are designed to operate using an electronic signal that is transmitted from the car's remote control (RF) transmitter to the owner's key fob. To stop unauthorized keyless entry the RF transmitters inside the key fob and in the car are programmed to only be activated when they're within a certain distance from one another. However, thieves can override this restriction using an attack known as the'relay attack'.
To accomplish this, two people work together one is positioned by the car, using the device that captures an electronic version of the key fob's signal. The other person 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 fools the car into thinking the key fob is close enough to unlock and begin the engine.
This type of heist used to require expensive equipment. Now, you can pick up relay transmitters on the cheap online and execute a heist in minutes. This is why it's popular among car thieves.
While certain cars are less vulnerable to this kind of theft than others, all modern vehicles with keyless entry are at risk. Researchers have tested 237 of the most popular automobiles and found that all of them can be stolen by this method.
Tesla vehicles are believed to be less vulnerable to this type of theft, however the company hasn't yet implemented UWB features that would effectively check distances on the car's signal and prevent relay attacks. The company has said that they'll implement this in the near future, however until then, they are vulnerable. That is why it's important to adopt a proactive approach to your vehicle security and install an anti-theft device that safeguards your keys and the car from such attacks.
CAN Injection Attack
Modern cars are designed to shield themselves from thieves by exchanging cryptographic data with the key to prove it's genuine. The system is believed to be safe, but thieves have found ways to get around it. They pretend to be the smart key, then send messages to the vehicle, and then drive away. To do that, they get access to the smart key's internal communications network.
Today, most cars are equipped with between 20 and 200 electronic control units, or ECUs, that control different aspects of the vehicle's operation. They communicate through an electronic network known as CAN bus. To ensure that power consumption is low the ECUs enter the sleep mode at low power. This mode is activated when they receive a wake up frame. These frames are typically sent by the ECU that manages the smart key or door. However, these messages aren't always authenticated or encrypted, which means that they could be snatched by criminals who have a low-cost and simple device.
They look for a place that allows them to connect directly to the wires for CAN connection. They are usually hidden in the headlights or in other locations in the front of the vehicle. To get them, you need to remove the bumper and make holes in the headlamp assemblies. The criminals then employ a device dubbed a CAN injection attacker to send fake messages that trick the car's security systems into unlocking the car and disengaging the engine immobilizer.
These devices can be purchased through 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 fix the issue in their current models, but the reality is that the thieves will continue to steal anything they can get their hands on. We can prevent this by implementing mechanical safety measures such as Discloks in all of our cars and parking them in well-lit, visible areas.
Jamming the Signal
In a variation of the relay attack that employs a device that is able to block the signal sent by key fobs while the vehicle is locked. The device could be in the pocket or hiding the location of a thief in the parking lot, or near the driveway that is being targeted. The owners don't know if the vehicle is locked after pressing the lock button. Instead, thieves can escape with the vehicle because the signal that normally locks the car has been blocked by the device of the criminal.
They also have devices that amplify signals from the key fob to unlock vehicles. The crooks can do this even when the key is in the driver's pocket, or hanging on an outside hook in the home. Once the car is unlocked, they can make use of an ordinary diagnostic port or computer hacker to program a blank key fob and gain control of the vehicle.
Car manufacturers have come up with a variety of anti-theft solutions to guard against these kinds of attacks. But thieves always find ways to defeat these measures.
For instance, they've begun using devices that transmit on the same frequency as remote key fobs in order to intercept their signals. The thieves copy the unlock code from the key fob, and then start the vehicle with this fake signal.
This method is very popular in the US and Europe where a lot of vehicles are sold with wireless technology that lets owners unlock and start their vehicle using a mobile app from their phones. This technology is expected to become increasingly popular as more and more manufacturers try to connect their vehicles to owners' smartphones.
It is crucial that drivers use best practices to 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 utilize a steering or gearstick locking device. It is also recommended to consider having a tracking device fitted to their car in case it gets stolen.
Flat Battery
This type of attack occurs more often than we think. Thieves make use of inexpensive devices to extend the signal from your key fob to unlock and begin cars even if they're turned off. Then they drive the car to the trailer or around a corner and take the car away. It is possible to shield your vehicle from this by installing an interrupter for the starter circuit. The most basic ones have an ON/OFF switch that shuts off the starter circuit. It costs around $15 and is easy to install.
Car thieves are always searching for new ways to take vehicles. The police as well as car manufacturers and insurance companies are always trying to catch up to their tactics and develop better here anti-theft systems for modern vehicles. But this does not stop thieves who are able to be quick to adapt and find ways around the latest anti theft measures.
For example, many criminals use devices that operate on the same radio frequency as the fob in order to block the signal. They put the device in their pocket or somewhere close to their vehicle, and it prevents the fob's lock signal from reaching the car, leaving the vehicle unlocked. This can be done in seconds. The device is cheap and easily accessible on the internet.
Hacking the computer system of the car is another option. This is more difficult but possible. Hackers have designed devices that plug into the diagnostic port of all vehicles and allow them to access the software. They can then program a blank fob to function. It is possible to do this on older cars as well, but it's more difficult if you remove the ignition.
As more vehicles are linked to smartphones of drivers the method is likely to become more popular as well. Once a criminal has the username and password for the vehicle app, they can then unlock the car or start it with the app on their phone. You can guard yourself by not putting valuables in your car and parking in garages.
