Cars Being Stolen With Keyless Entry
If car owners throw their keys on the table or next to their door, they may unknowingly be allowing thieves to steal their signal. This relay attack is one of the advanced methods criminals are using to steal brand new keyless vehicles.
All keyless ignition cars emit a low-power radio signal looking for a matching fob to respond. If the signal is captured and recreated, it can be used unlock the car, and also to start it.
Relay Attack
Imagine your car parked in your driveway with your key fob inside your home. You're confident that your car is safe, but unnoticed by you sophisticated thieves are planning an heist. These thieves use technology to hack into vehicles via digital chinks. Known as relay theft, it's becoming a common way to steal cars that have keyless entry.
The keyless entry system found in cars is controlled by a signal sent by the car's radio transmitter to the key fob. To stop unauthorized keyless entry, the RF transmitters in the key fob and in the car are programmed to only be activated when they're within a certain distance of each other. However, thieves are able to override this restriction using an attack known as the'relay attack'.
To do so two people work in tandem: one stands by the car, using a device that captures digitally the key fob's signal. The other, standing by the house of the owner and using a second device to send the key fob's signal to the car. This trickery tricks the car into believing that the key fob is at the distance needed to allow the vehicle to start and unlock. vehicle.
In the past, this kind of heist required expensive equipment to carry out. Today, you can purchase a relay transmitter for a small price online and pull off an heist in just a few minutes. This is the reason car thieves love it.
While certain cars are less prone to this type of theft than others, all modern cars that have keyless entry are at risk. In fact researchers have examined 237 vehicles that are popular and found that they could be all stolen using this method.
Tesla vehicles are believed to be less susceptible to this kind of theft. However Tesla hasn't implemented UWB technologies that would enable it to perform distance checks and stop relay attacks. The company has stated that they'll implement this in the near future, however until then, they are vulnerable. That's why it's essential to be proactive about your vehicle security and install an anti-theft tool that safeguards your keys and car from these types of attacks.
CAN Injection Attack
Modern vehicles are designed to guard themselves from thieves by exchanging cryptographic messages with the key to prove it's genuine. This method is generally thought to be secure, but thieves have found a way 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.
The majority of cars today are fitted with between 20 and 200 electronic control units, also known as ECUs, which control various aspects of the vehicle's operation. They communicate with each other via an electronic network referred to as CAN bus. These ECUs enter a low-power sleep mode to lower their power consumption. This mode is activated when the ECUs receive a "wake up" frame. These frames typically come via the door or smart key receiver ECU. However they aren't always authenticated or encrypted so they could be snatched by criminals who have a low-cost and simple device.
They search for a spot that allows them to connect directly to the wires for CAN connection. They usually hide in the headlights or in other locations in the front of the vehicle. To get them, you need to pull the bumper and cut holes in the headlamp assemblies. The thieves employ a device known as an CAN injection attack. It is used to send fake messages which trick the car's safety systems into unlocking and disengaging the engine immobilizer.
The devices are available through the Dark Web and work with the majority of 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 manufacturers fix the issue in their current models, but the reality is that thieves will continue to steal whatever they can get their hands on. The best thing we can do is make an effort to prevent this from happening by installing security measures that are mechanical such as Discloks on all of cars, and making sure that they are always parked in well-lit areas that are clearly visible to passers-by.
Jamming the Signal
In a variant different to the relay attack, thieves could make use of a device to block the signal sent from an electronic key fob if the vehicle is locked. The device could be hidden in the pocket or hiding where a burglar is hiding on an open parking lot or in the driveway being targeted. When owners hit the button to lock their fobs and leave they don't consider whether or not the car actually locks. The device used by the crook blocks the signal that locks the car. Therefore, thieves could drive away with the vehicle.
They also make use of devices that amplify signals from the key fob to unlock vehicles. The crooks are able to do this even if the key is in the pocket of a driver, or hanging on an outside hook in the home. After the car has been unlocked, they can make use of an ordinary computer hacker to program an unlocked key fob to gain control over the vehicle.
Automobile manufacturers have come up with a range of anti-theft systems to safeguard against these types of attacks. However, thieves will always come up with new ways to beat these measures.
For instance, they've begun using devices that transmit on the same radio frequency as remote key fobs in order to intercept their signals. The crooks can then copy the unlock code of the key fob and start the car with this fake signal.
This method is especially popular in the US, where many cars are equipped with wireless technology. Owners can start and unlock their car through a mobile application on their phone. This technology is expected to become more popular as more and more companies try to connect their vehicles to owners' smartphones.
In addition to incorporating anti-theft technology in vehicles, it's crucial for drivers to use the best practices when they park their cars. They should never leave their key fobs in the ignition, and should always ensure that the vehicle is locked completely when they're not using it and should make use of the steering wheel or a gearstick lock, if it is possible. They should also consider fitting a tracking device to their vehicle in the event it's stolen.
Flat Battery
This kind of here attack is more prevalent than people think. Thieves make use of inexpensive devices to extend the signal from your key fob to open and start the car, even if it's turned off. Then they drive the vehicle to the trailer or around a corner to take the car away. It is possible to shield your vehicle from this by installing an interrupter switch for the starter circuit. Simpler versions come with an ON/OFF button which interrupts the circuit. It costs around $15 and is simple to install.
Car thieves are always working on new ways to get into vehicles and steal them. The police as well as the car makers and insurance companies are always trying to keep up to their tactics and offer better anti-theft solutions for modern vehicles. But that doesn't stop thieves, who are able to be quick to adapt and find ways to circumvent the most recent anti-theft measures.
For instance, many criminals employ a device that works on the same frequency as the fob to block the signal. They place the device in their pocket or somewhere close to their vehicle, and it stops the fob's lock commands from reaching the car and thereby leaving it unlocked. This can be accomplished in just a few seconds. The device is inexpensive and is available online.
Hacking the computer system of the car is another option. This is harder but still feasible. Hackers have developed devices that plug into the diagnostic port of all cars and allow them to connect to the software. From there, they are able to program the blank key fob to start working. It is possible to do this on older cars too, but it's more difficult if you remove the ignition.
As more vehicles are connected to the phones of drivers the method is likely to be more popular. Once a burglar has gained the username and password to the vehicle app they are able to unlock the car or start it using the app on their phone. You can protect yourself by not putting valuables in your car and parking in garages.
