Cars Being Stolen With Keyless Entry
If car owners throw their keys on the table or at their doors, they could not realize that they are allowing thieves to steal their signal. This relay attack is a high-tech method criminals use to steal new keyless vehicles.
All 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 being parked safely in your driveway, with the key fob tucked away in your home. You may think your vehicle is secure, but sophisticated thieves are planning to steal your car without you even knowing. Instead of slamming windows and jiggling locks, they are leveraging technology to gain access to cars through digital chinks in their armor. This is known as relay theft, it's an increasingly common method of stealing vehicles with 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 stop unauthorized keyless entry the RF transmitters on the key fob and car are programmed to only be activated when they're within a certain distance of each other. However, a thief can bypass this limitation with a technique called the 'relay attack'.
To do so two people work together One stands near the car with a device that captures an electronic version of the key fob's signal. The other, who is at the owner's home and uses a different device to transmit the signal from the key fob to the car. This trickery fools the car into thinking the key fob is close enough to be able to unlock it and begin the engine.
In the past, this kind of attack required expensive equipment to carry out. However, now you can purchase relay transmitters for cheap online and execute the heist in just a few minutes. This is the reason why car thieves love it.
All modern vehicles with keys are at risk. Certain cars are more susceptible to this type than others. In fact researchers have tested 237 vehicles that are popular and found that they could all be stolen using this method.
Tesla vehicles are said to be less vulnerable to this kind of theft. However Tesla hasn't yet implemented UWB technologies that would allow it to conduct distance checks and prevent relay attacks. The company has stated that they'll implement this in the near future, but until then, they are vulnerable. Installing an anti-theft device that protects both your car keys and your keys against such attacks is a proactive approach to ensure the security of your vehicle.
CAN Injection Attack
Modern vehicles can defend themselves from theft by exchanging encrypted messages with the key in order to confirm its authenticity. The system is thought to be secure, however thieves have found ways around it. They can impersonate the smart key and send messages to the vehicle letting it unlock the doors, disable its engine immobilizer, then let them drive away. To do that they have access to the smart key's internal communication network.
Today, most cars are equipped with between 20 and 200 electronic control units, also known as ECUs, which control various aspects of the vehicle's operation. They communicate through an electronic network known as CAN bus. To reduce power consumption the ECUs go into sleep mode with low power that is activated when they receive a 'wake up' frame. These frames are usually sent by the ECU that controls the smart key or door. However they aren't always encrypted or authenticated so they could be snatched by criminals who have a low-cost and basic device.
They search for a spot that allows them to connect directly to the wires for CAN connection. They're usually hidden in the headlights or in the front of the car, and can be accessed by removing the bumper and cutting holes in the headlamp assembly to expose the wires. The thieves then employ a device dubbed an CAN injection attacker to send fake messages which can trick the car's security systems into unlocking the car and disengaging 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 manufacturers fix the issue in their current models, but the fact is that the thieves will continue to grab everything they can lay their hands on. We can prevent this by installing mechanical safety measures such as Discloks in all our vehicles and parking them in well-lit, well-lit areas.
Blocking the Signal
In a different variant of the relay attack, thieves may employ a device to block the signal that is sent by the 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 near the driveway being targeted. Owners aren't able to verify whether the vehicle is locked when they press the lock button. The device used by the criminal blocks the signal that locks the vehicle. Thus, thieves are able to leave 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 a driver's pocket, or hanging from a hook inside the home. Once the car is unlocked, they can use the standard diagnostic port or computer hackers to program the blank key fob and gain control over the vehicle.
To protect against this type of attack, car makers have created a variety of anti-theft gadgets. But thieves always find ways to defeat these measures.
They've started using devices that transmit at the same frequency as remote keyfobs to intercept signals. The crooks then copy the unlock code of the key fob and begin the vehicle using this fake signal.
This method is particularly popular in the US in which many vehicles come with wireless technology. Owners can start and unlock their car by using a mobile app on their smartphone. This technology is expected to become more popular as more and more companies attempt to link their vehicles with their owner's smartphones.
In addition to incorporating anti-theft technology in vehicles, it's crucial for drivers to follow the best practices when parking their cars. They should not leave the keys in ignition and always lock the car when they are not in it. If possible, they should also use the gearstick or steering locking device. They should also think about installing a tracking device onto their vehicle in the event it's stolen.
Flat Battery
This type of attack occurs more often than we think. Thieves employ cheap devices to extend the signal from your key fob to unlock and begin the car, even if it's switched off. They then drive the car around the corner or to a trailer and take off with it. It would be possible to protect your car from this by installing an interrupter switch for the starter circuit. The most basic ones have an ON/OFF switch which interrupts the starter circuit. It's about $15 and is easy to install.
Car thieves are constantly searching for new ways to rob vehicles. Police, car manufacturers and insurance companies are constantly trying to stay abreast of the latest techniques and offer better anti-theft here systems for modern vehicles. But this doesn't stop thieves who can be quick to adapt and find ways to circumvent the latest anti-theft technology.
For instance, many criminals employ a device that works on the same frequency as the fob in order to block the signal. They place the device in their pockets or somewhere close to their vehicle, and it blocks the fob's lock commands from reaching the vehicle which leaves the vehicle unlocked. This can be done in just a few seconds. The device is cheap and easily available online.
Another option is to hack into the car's computer system. This is more difficult, but nevertheless possible. All cars have a diagnostic port, and hackers have developed devices that plug into them and allow them access the software of the car. From there, they can program a blank key fob and get it to work. This can also be done on older vehicles, but it is more difficult without removal of the ignition lock.
As more vehicles are linked to smartphones of drivers, this method may become more popular too. Once a burglar has gained the username and password for the vehicle app and then they can unlock or start the car using the app on their phone. You can safeguard yourself by not putting valuables inside your car, and parking in garages.
