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 steal their signal. This relay attack is just one of the latest techniques criminals are using to steal brand new keyless cars.
All keyless ignition vehicles emit a low power radio signal to find the fob that matches. If the signal is captured and recreated, it can be used to unlock the car and to start it.
Relay Attack
Imagine your car being parked safely in the driveway, with the key fob safely in your home. You're confident that your car is safe, but unnoticed by you sophisticated thieves are planning an attack. Instead of breaking windows or jimmying locks, they are using technology to gain access to cars through digital cracks in their armor. Known as relay theft, it's an increasingly common way to steal cars that have keyless entry.
The keyless entry system found in cars is controlled by a signal sent from the car's RF transmitter to the 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 to turn on when they are within a specified distance from one another. However, thieves can overcome this limitation using a technique known as the'relay attack'.
Two individuals are required to perform this: one person stands close to the car and utilizes a device to capture an electronic version of the the key fob. The other person, who is at the owner's home, uses a second gadget to transmit the signal from the key fob to the car. This trick tricks the car into thinking the key fob is close enough to be able to unlock it and start the engine.
In the past, this type of heist required expensive equipment to carry out. However, now you can buy a relay transmitter on the low cost online and conduct an heist in a matter of minutes. This is why car thieves love it.
All modern vehicles that have keyless access are vulnerable. Certain cars are more susceptible to this kind of attack than others. In fact, researchers have tested 237 popular vehicles and found that they could be all stolen using this method.
Tesla vehicles are said to be less susceptible to this kind of theft. However Tesla hasn't implemented UWB technologies that would allow it to perform distance checks and prevent relay attacks. The company has stated that they will do so in the future, but for now they are vulnerable. Installing an anti-theft device that protects both your car keys and your keys against such attacks is a proactive method to ensure the security of your car.
CAN Injection Attack
Modern vehicles are designed to guard themselves from theft 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 simply impersonate the smart key and send messages to the car, letting it unlock the doors, turn off its engine immobilizer, and then go on their way. To do that, they get access to the smart key's internal communications network.
The majority of cars today are fitted with between 20 and over 200 electronic control units, also known as ECUs, that control different aspects of the vehicle's operation. They communicate via an electronic network known as CAN bus. These ECUs enter 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 by the ECU that controls the smart key or door. These messages aren't always authenticated or encrypted. This means that thieves can capture them using an inexpensive and simple device.
They look for a place that allows them to connect directly to the wires for CAN connection. They're usually hidden in 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 then employ a device known as an CAN injection attacker, which is used to send fake messages that can trick the car's security systems to unlock it and disable its engine immobilizer.
These devices can be bought on the Dark Web and work with the majority of 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 address it in their car key stolen what do i do existing models, but the reality is that these thieves will continue to grab everything they can lay their hands on. The best thing we can do is to attempt to stop this from happening by installing security measures that are mechanical like Discloks on our cars and ensuring that they are always parked in well-lit areas that are easily visible to pedestrians.
Blocking the Signal
In a different variation of the relay attack, thieves could employ a device to block the signal that is sent by the key fob when the car is locked. The device may be inside the pocket of a thief in a parking lot or in a hideout near the driveway that is being targeted. Once owners press the lock button on their fobs and walk away they don't consider whether or not their car is actually locks. Instead, thieves can escape with the vehicle because the signal that normally locks the car has been blocked by the crook's device.
The crooks also employ devices to amplify the signal from the key fob to unlock vehicles. The crooks are able to do this even when the key is inside a pocket of a driver, or hanging from an outside hook in the home. When the car is locked, they can use an ordinary computer hacker to program the blank key fob and gain control over the vehicle.
To protect against this type of attack, car manufacturers have developed a variety of anti-theft gadgets. But, as always, thieves come up with ways to thwart these measures.
They've started using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The crooks can then copy the key fob's unlock code and then start the car with this fake signal.
This method is very popular in the US and Europe where many vehicles are sold with wireless technology that allows owners to unlock and start their vehicle by using a mobile application from their phones. This technology is expected to become increasingly popular as more and more manufacturers try to connect their vehicles with their owner's smartphones.
In addition to incorporating anti-theft technology in vehicles, it's vital for drivers to follow the best practices when they park their cars. It is not advisable to leave the keys in ignition and lock the car when they are not in it. If possible they should also utilize a gearstick lock or steering device. They should also consider fitting a tracking device to their vehicle in case it is stolen.
Flat Battery
This kind of attack is more frequent than most people realize. The thieves use low-cost devices that increase the signal of your key fob to unlock and start your car even if it is off. Then, they drive the car to a trailer or around a corner, and take the car away. It is possible to protect your vehicle from this by installing an interrupter switch for the starter circuit. The simplest ones are an ON/OFF switch which interrupts the starter circuit. It costs about $15 and is easy enough to install yourself.
Car thieves are constantly 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 anti-theft systems for the latest cars. However, that doesn't stop thieves who are able to adapt quickly and discover ways to bypass the latest anti-theft measures.
Many thieves block the signal by using devices that operate on the same radio frequency as the fob. They put the device in their pockets or in a location near their vehicle, and it stops the fob's lock command from reaching the vehicle which leaves the vehicle unlocked. This can be accomplished in a matter of seconds. The device is cheap and easily available online.
Another strategy is to hack into the car's computer system. This is more difficult but still possible. All cars have an diagnostic port and hackers have designed devices that plug into them and let them access the software in the car. From there, they can program a blank key fob and start working. It is possible to do this with older cars too however it is more difficult without taking out the ignition.
As more vehicles are connected to smartphones of drivers the method is likely to become more popular as well. Once a thief has the username and password to a vehicle app, they can unlock or start the vehicle by using the application. 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 secured parking lot.
