Cars Being Stolen With Keyless Entry
Car owners who toss their keys on a table or near their front door could be permitting thieves to steal the signal. This relay attack is a sophisticated method criminals use to steal new keyless vehicles.
Keyless ignition cars emit a low-power radio signal seeking a compatible fob that can respond. If the signal is captured and recreated, it can be used unlock the car and to start it.
Relay Attack
Imagine your car safely in your driveway, and your key fob inside your home. You may think your car is safe, but sophisticated thieves are planning a heist without you being aware. Instead of slamming windows and jiggling locks, they are using technology to gain access to cars through digital cracks in their armor. This method of stealing cars with keyless access is called relay theft.
The keyless entry system that is found in cars is controlled by a signal sent by the car's RF transmitter to the key fob. To stop keyless entry by intruders the RF transmitters on the key fob and the car are programmed to activate when they are within a specified distance from each other. However, thieves are able to overcome this limitation using a technique known as the'relay attack'.
To do so two people work together one is positioned by the car, using an instrument that records an electronic version of the key fob's signal. The other, who is at the owner's house, uses a second device to send the key fob's signal down to the car. This trick tricked the car into thinking that the key fob is close enough to allow it to unlock and start the engine.
This type of heist was once a costly process that required expensive equipment. Today, you can purchase a relay transmitter for a small price on the internet and complete an heist in a matter of minutes. This is why car thieves love it.
While some cars are less susceptible to this type of theft than others, all modern cars that have keyless entry are vulnerable. In fact, researchers have tested 237 popular cars and found that they can be all stolen using this method.
Tesla vehicles are said to be less susceptible to this kind of theft. However, the company hasn't yet implemented UWB technologies that would allow it to perform distance checks and stop attacks via relay. The company has promised to implement this feature in the near future, but for now, they remain vulnerable. Installing an anti-theft system that safeguards your car and your keys against such a threat is a proactive way to ensure your car's security.
CAN Injection Attack
Modern cars can guard themselves against thieves by sending encrypted messages to the key in order to verify its authenticity. The system is generally believed to be secure, but thieves have found a way to circumvent it. They fake the identity of a smart key, transmit messages to the vehicle and then drive off. To achieve this, they need access to the smart keys' internal communication network.
Today, most automobiles are equipped with between 20 and 200 electronic control units (or ECUs) that control various aspects of the car's operation. They communicate with each other via a network known as CAN bus. These ECUs are put into a low power sleep mode to decrease 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. These messages aren't always authenticated or encrypted. This means that criminals can intercept them with an inexpensive and simple device.
They look for a place that allows them to connect directly to the wires of the CAN connection. They are usually hidden in the headlights or in the front of the car and can be accessed by pulling the bumper off and cutting holes in the headlamp assembly to expose the wires. The thieves use an instrument known as an CAN injection attack to send out fake messages that trick the car's safety systems to unlock and disable the engine immobilizer.
These devices are available for sale on the Dark Web, and work for all major car makers including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and many more. The researchers who discovered this CAN Injection attack are recommending that all car manufacturers fix it in their existing models, but the reality is that thieves will continue to grab whatever they can get their hands on. We can stop this from happening by implementing mechanical safety measures like Discloks in all our vehicles and parking them in well-lit, visible areas.
The Signal is blocked
In a different variation of the relay attack, thieves can employ a device to block the signal sent from a key fob when the vehicle is locked. The device could be found in the pocket or hiding the location of a thief in the parking lot, or even near the driveway being targeted. Once owners hit the lock button on their fobs, and then walk away, they don't think about whether or not their car is really locked. The device used by the criminal block the signal that locks the car. Therefore, thieves could drive away with the vehicle.
They also use devices that amplify signals from the key fob to unlock vehicles. The crooks are able to do this even when the key is in a driver's pocket, or hanging from a hook inside the home. After the car is unlocked, hackers can use a standard diagnosis port to program the fob with a blank.
To safeguard against this kind of attack, car makers have developed a variety of anti-theft gadgets. However, thieves are always finding ways to beat these measures.
They've read more begun using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The thieves copy the unlock code of the key fob and start the vehicle using this fake signal.
This method is particularly popular in the US, where many cars come with wireless technology. Owners can unlock and start their vehicle through a mobile application on their smartphone. This technology will likely become more popular as more car manufacturers attempt to link their cars with their owners' smartphones.
In addition to implementing anti-theft systems in vehicles, it's vital for drivers to follow the best practices when they park their vehicles. They should never leave the keys in ignition and lock the car when they are not in it. If they can they should also utilize a steering or gearstick locking device. It is also recommended to think about installing a tracking device onto their vehicle in case it's stolen.
Flat Battery
This kind of attack is more frequent than most people realize. Thieves make use of inexpensive devices to extend the signal from your key fob to unlock and begin the car, even if it's shut off. They then simply drive the car around a corner or even to a trailer and leave with it. Installing a starter circuit interruption switch can protect your vehicle from this. Simpler versions include an ON/OFF button that shuts off the circuit. It costs about $15 and is easy enough to put in yourself.
Car thieves are always looking for new ways to get into vehicles and take them away. Police, car manufacturers and insurance companies are always trying to stay abreast of the latest techniques and offer better anti theft systems for modern vehicles. But that doesn't stop the thieves who are able change quickly and discover ways to bypass the most up-to-date anti-theft systems.
For instance, a lot of criminals use devices that operate on the same radio frequency as the fob to block the signal. The device is placed in the pocket or near the vehicle, and stops the fob from sending the lock command to the vehicle. This can be done within just a few seconds. The device is affordable and is available on the internet.
Another tactic is to hack into the car's computer system. This is more difficult, but possible. Hackers have created devices that plug into the diagnostic port of all cars and allow them to access the software. They can then program a blank fob to function. It is possible to do this on older vehicles also however it is more difficult if you remove the ignition.
This method could be more popular if more vehicles are connected with drivers' mobile phones. Once a thief gets the username and password to an app for vehicles and then they can open the car or get it started using the app on their phone. Fortunately, you can protect yourself from these types of attacks by not leaving valuables in your car and putting it in a garage or secure parking lot.
