Cars Being Stolen With Keyless Entry
If car owners leave their keys on the table or near their door, they may unknowingly be allowing thieves to hijack their signal. This relay attack is a sophisticated technique used by criminals to steal new keyless vehicles.
All keyless ignition vehicles emit a low-power radio signal to find the fob that matches. If the signal is recorded and recreated, it can be used to unlock the car and begin it up.
Relay Attack
Imagine your car parked in your driveway with your key fob in your home. You might think that your car is secure, but sophisticated thieves are planning a heist, without you knowing. These thieves use technology to snoop on vehicles through digital chinks. This is known as relay theft, it's a more common way to steal cars with keyless entry.
Keyless entry cars are designed to function using a signal sent by the car's remote control (RF) transmitter to the owner's key fob. To ensure that keyless entry is not accessed by intruders the RF transmitters that are on the key fob as well as the car are programmed only to be activated when they are within a certain distance from one another. The thief can circumvent this limitation employing a technique called the'relay-attack'.
To accomplish this two people work together: one stands by the car with an instrument that records a digitized version of the key fob's signal. The other, who is at the home of the owner and using a second device to send the key fob's signal down to the car. This trickery tricks the car into thinking that the key fob is at the distance needed to unlock and start the vehicle.
In the past, this type of heist required expensive equipment to carry out. You can now buy a relay transmitter for a small price on the internet and complete an heist in just a few minutes. This is why car thieves love it.
All modern cars with keyless access are vulnerable. Certain cars are more vulnerable to this type than others. In fact researchers have examined 237 vehicles that are popular and found that they can all be stolen using this method.
Tesla vehicles are believed to be less susceptible to this kind of theft. However Tesla hasn't yet implemented UWB technologies that would allow it to conduct distance checks and stop attacks via relay. The company has stated that they'll implement this in the near future, but until then they are vulnerable. Installing an anti-theft system that guards your car and your keys against these types of attacks is a proactive way to ensure your car's security.
CAN Injection Attack
Modern cars can protect themselves from theft by transferring encrypted messages using the key in order to confirm its authenticity. This method is generally thought to be secure, but criminals have found a way to circumvent it. They simply 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 achieve this, they need access to the smart keys' internal communication network.
Most cars today are equipped with between 20 and over 200 electronic control units, or ECUs, that control different aspects of the vehicle's operation. They communicate with each other via an electronic network referred to as CAN bus. These ECUs are put into a low power sleep mode to lower their power consumption. This mode is activated when ECUs receive an "wake up" frame. These frames typically come through the door or a 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 basic device.
To accomplish this, they search for a place where they can directly connect to the CAN bus connection wires. They are usually hidden in the headlights or in front of the vehicle, and can be accessed by pulling the bumper off and cutting holes in the headlamp assembly to expose the wires. The criminals then use a device called a CAN injection attacker to send fake messages that trick the car's security systems into unlocking it and disengaging the engine immobilizer.
These devices are for sale on the Dark Web, and work for all major car manufacturers, including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and more. Researchers who have discovered the CAN Injection attack recommend that all car manufacturers fix this issue in their existing models. However, these criminals will continue taking any opportunity they can. We can stop this from happening by installing mechanical security measures, such as Discloks inside all of our cars and parking them in well-lit, well-lit areas.
Blocking the Signal
In a different variation of the relay attack, thieves may make use of a device to block the signal that is sent by a key fob when the car is locked. The device could be found in the pocket of a thief in a parking space or in a hiding spot close to the driveway that is being targeted. Owners aren't able to verify if the vehicle is locked after pressing the lock button. Instead, thieves could take off with the car since the signal that normally locks the car is blocked by the device of the criminal.
They also use devices that amplify signals from the key fob to unlock vehicles. They can even accomplish this if the key is in the pocket of the driver or hanging from a hook in the house. After the car is locked, hackers can use an ordinary diagnosis port to create a blank fob.
Car manufacturers have developed a range of anti-theft systems to safeguard against these types of attacks. But thieves always come up with ways to thwart these measures.
They've been using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The get more info thieves then copy the unlock code from the key fob and start the vehicle using this fake signal.
This method is particularly popular in the US and Europe where a lot of vehicles are equipped with wireless technology that allows owners to unlock and start their cars by using a mobile application on their phone. This technology will likely be more commonplace as more car manufacturers attempt to connect their cars to their owners smartphones.
It is important that drivers follow the best practices when parking their vehicles. It is not advisable to leave the keys in ignition and secure the car when not in it. If they can, they should also use a gearstick lock or steering device. They should also think about installing a tracking device on their vehicle in the event that it's stolen.
Flat Battery
This kind of attack is more frequent than many people believe. Thieves use cheap devices to extend the signal from your key fob to unlock and begin cars even if they're shut off. Then, they drive the car to an unmarked trailer or around a corner, and take it away. It would be possible to protect your vehicle from this by installing an interrupter for the starter circuit. Simpler versions include an ON/OFF button that interrupts the circuit. It costs around $15 and is simple to install.
Car thieves are always looking for new ways to take vehicles. Police, car manufacturers and insurance companies are always trying to stay abreast of the latest tactics and provide more effective anti-theft systems for modern vehicles. However, this isn't stopping thieves who easily adapt and find ways to circumvent the latest anti theft measures.
For instance, a lot of criminals employ devices that operate on the same frequency as the fob in order to block the signal. They place the device in their pocket or close to their vehicle, and it stops the fob's lock commands from reaching the vehicle which leaves the vehicle unlocked. This can be accomplished in just a few seconds. The device is affordable and is available online.
Another option is to hack the car's computer system. This is more difficult, but it is still feasible. Hackers have developed 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 too however it is more difficult without taking out the ignition.
This method is likely to become more popular as more vehicles are connected with drivers' phones. Once a thief gets the username and password for an app for vehicles they are able to unlock or start the car by using the app on their phone. Fortunately, you can defend yourself from these kinds of attacks by not leaving valuables in your car, and then parking it in a garage or secure parking lot.
