Cars Being Stolen With Keyless Entry
Car owners who toss their keys on a table or near their front door could be allowing thieves to hijack the signal. This relay attack is one of the advanced methods criminals are using to steal brand new keyless cars.
Keyless ignition cars emit a low-power radio signal in search of a fob to 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 in your driveway, and your key fob in your home. You may be confident that your car is secure but sophisticated thieves are planning to steal your car without you knowing. Instead of slamming windows or jiggling locks, these thieves are leveraging technology to gain access to cars through digital cracks in their armor. This is known as relay theft, it's a more popular method of stealing cars with keyless entry.
The keyless entry system that is found in cars is controlled by a signal from the car's RF transmitter to the key fob. To stop unauthorized keyless entry the RF transmitters inside the key fob as well as in the car are programmed to activate only when they're within a certain distance from each other. The thief can circumvent this limitation using a technique known as the relay-attack.
Two people are required to complete this: one person is close to the car and utilizes a device to capture a digitalized version of the the key fob. The other, who is at the owner's house and using a second device to send the key fob's signal to the car. This trick tricked the car into thinking the key fob is near enough to be able to unlock it and begin the engine.
This type of attack was once a costly process that required expensive equipment. However, now you can purchase relay transmitters for inexpensive online market and carry out the heist in just a few minutes. This is why car thieves are enthralled by it.
All modern cars with keys are at risk. Some cars are more vulnerable to this type of attack than others. Researchers have tested 237 popular cars and found that every one of them are susceptible to being stolen using this method.
Tesla vehicles are said to be less susceptible to this kind of theft. However Tesla hasn't yet implemented UWB technologies that would enable it to perform distance checks and stop attacks via relay. The company has stated that they will do so in the future, but until then they are still vulnerable. That is why it's important to take a proactive approach to your car security 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 thieves by exchanging cryptographic messages with the key to prove that it's authentic. This method is generally thought to be secure, but thieves have found a way around it. They simply impersonate the smart key and send other messages to the car letting it unlock the doors, disable its engine immobilizer, and let them go on their way. To achieve this, they need access to the smart keys' internal communication network.
Nowadays, the majority of cars are fitted with between 20 and 200 electronic control units (or ECUs) that manage different aspects of the car's operation. They communicate with each other via an electronic network referred to as CAN bus. To reduce power consumption the ECUs enter the sleep mode at low power. This mode is activated when they receive a 'wake up frame. These frames are usually sent through the door or a smart key receiver ECU. These messages aren't always authenticated or encrypted. This means that thieves can take them over with a simple and cheap device.
They search for a location where they can connect directly to the wires for CAN connection. They are usually hidden within the headlights or in front of the vehicle, and are accessible by pulling the bumper and cutting holes in the headlamp assembly to expose them. The thieves employ the device referred to as a CAN injection attack to send fake messages that trick the car's safety systems into unlocking and disengaging get more info the engine immobilizer.
These devices are available for sale on the Dark Web, and work for most of the major car makers which include BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and more. Researchers who discovered the CAN Injection attack recommend that all car makers fix this in their existing models. However, the thieves will continue taking everything they can. The best we can do is to try and prevent this by installing mechanical security measures like Discloks on all our vehicles, and making sure that they are always located in areas with adequate lighting that are clearly visible to people passing by.
Jamming the Signal
In a different variant of the relay attack, thieves may use a gadget to jam the signal sent from a key fob when the vehicle is locked. The device could be found in the pocket or hidden where a burglar is hiding on an open parking lot or in the driveway that is being targeted. Once the owners hit the button to lock their fobs and leave they don't consider whether or not their car is really locked. The device used by the crook interferes with the signal to lock the car. Therefore, thieves can drive away with the vehicle.
They also make use of devices that amplify signals from the key fob to unlock vehicles. They may even do this when the key is in the driver's pocket or hanging from its hook in the home. After the car has been unlocked, they can make use of a standard computer hacker to program an unlocked key fob to gain control over the vehicle.
Automobile manufacturers have developed a variety of anti-theft solutions to safeguard against these types of attacks. But, thieves are constantly finding ways to beat these measures.
They've started using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The thieves then copy the unlock code of the key fob and begin the vehicle with this fake signal.
This method is particularly popular in the US, where many cars have wireless technology. Owners can start and unlock their car by using a mobile app on their smartphone. This technology is expected to gain popularity as more and more car manufacturers attempt to link their vehicles to their owners' smartphones.
In addition to implementing anti-theft systems in vehicles, it's crucial for drivers to use the best practices when parking their vehicles. They shouldn't leave their keys in the ignition, should always ensure that their car is fully locked when they're not using it and should make use of a steering wheel or gearstick lock, if they can. They should also think about installing a tracking device to their car in case it gets stolen.
Flat Battery
This kind of attack occurs more often than people realize. The thieves use cheap devices that extend the signal of your key fob in order to unlock and start your car even when it's off. Then they drive the car to a trailer or around a corner, and take the vehicle away. Installing an interrupter switch for the starter circuit will protect your vehicle from this. The most basic ones have an ON/OFF switch that interrupts the starter circuit. It's about $15 and is simple to install.
Car thieves are always trying new ways to enter vehicles and then steal them. The police, car makers and insurance companies are always trying to keep up with their tactics and provide better anti-theft systems for modern vehicles. However, that doesn't stop thieves, who are able to adapt quickly and find ways to get around the latest anti-theft measures.
For instance, a lot of thieves use devices that operate on the same radio frequency as the fob in order to block the signal. The device is tucked away in the pocket or near the vehicle and prevents the fob from sending the lock command to the car. This can be done in a matter of seconds. The device is inexpensive and is available online.
Another strategy is to hack into the car's computer system. This is more difficult but still possible. Hackers have developed devices that connect to the diagnostic port of all cars and allow them to access the software. They can then program an unfinished fob to work. This can also be done on older vehicles, but it is more difficult to do so without taking off the ignition lock.
As more vehicles are connected to the phones of drivers, this method may become more popular as well. Once a criminal has the username and password to an application for vehicles they can open or start the vehicle using the app. Fortunately, you can protect yourself from these types of attacks by not leaving valuables in your car and parking it in a garage or secured parking lot.
