Cars Being Stolen With Keyless Entry
Car owners who throw their keys on tables or near their front doors may be unwittingly giving thieves the ability to take over the signal. This relay attack is a sophisticated method criminals use to steal keyless vehicles.
All keyless ignition cars emit a low-power radio signal seeking a compatible fob to respond. If the signal is captured and recreated it can be used to unlock the car and begin it up.
Relay Attack
Imagine your car being parked safely in your driveway, with the key fob sitting safely inside your home. You may be confident that your car is safe however, sophisticated thieves are planning a heist without you being aware. Instead of slamming windows and jiggling locks, thieves are using technology to gain access to cars through digital chinks 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 from the car's RF transmitter to the key fob. To stop unauthorized keyless entry, the RF transmitters in the key fob and car are programmed to only activate when they're within a specific distance of each other. However, thieves are able to bypass this limitation with an attack known as the'relay attack'.
To accomplish this, two people work in tandem: one stands by the car and uses a device that captures a digitized version of the key fob's signal. The other, standing by the owner's house and using a second device to send the key fob signal back down to the car. This trick tricks the car into thinking the key fob is near enough to unlock and start it up.
This type of heist was once a costly process that required expensive equipment. Now, you can purchase relay transmitters on the cheap online and execute an heist in a matter of minutes. This is why it's so popular among car thieves.
While some cars are less vulnerable to this kind of theft than others, all modern cars that have keyless entry are at risk. In fact researchers have examined 237 popular vehicles and found that they can be all stolen using this method.
Tesla vehicles are believed to be less susceptible to this type of theft, however the company has not yet implemented UWB features that could effectively check distances on the car's signal and prevent relay attacks. The company has stated that they will do so in the future, but until then they are still vulnerable. This is why it's crucial to adopt a proactive approach to your security in your car and install an anti-theft kit that safeguards your keys and vehicle from these kinds of attacks.
CAN Injection Attack
Modern cars can protect themselves from thieves by transferring encrypted messages using the key in order to confirm its authenticity. This method is generally thought to be secure, however criminals have found a way around it. They can impersonate the smart key and send messages to the car, letting it unlock the doors, turn off its engine immobilizer, and let them leave the car. To do this, they gain access to the smart keys' internal communications network.
These days, most cars are equipped with between 20 to 200 electronic control units (or ECUs) that manage different aspects of the car's operation. They communicate through an electronic network known as CAN bus. To reduce power consumption the ECUs go into a low-power sleep mode that's activated when they 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 encrypted or authenticated. This means that criminals are able to take them over with a simple and cheap device.
They look for a place that allows them to connect directly to the wires for CAN connection. They usually are hidden in the headlights or in other places in the front of the vehicle. To get them, you need to pull the bumper and cut holes in the headlamp assemblies. The thieves use a device known as an CAN injection attack to send fake messages which can trick the security systems of the car into unlocking and disengaging the engine immobilizer.
These devices can be purchased through 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. Researchers who have discovered the CAN Injection attack recommend that all car makers address the issue in their current models. However, these criminals will continue to steal everything they can. The best we can do is to try and prevent this by putting in mechanical security measures like Discloks on our vehicles and ensuring that they are always located in areas with adequate lighting that are clearly visible to passers-by.
Blocking the Signal
In a variation of the relay attack that employs a device that can be used to block the signal from the key fob when the car is locked. The device may be hidden in the pocket of a burglar in a parking space or in a hidden spot close to the driveway that is being targeted. Owners don't check whether the car is locked after pressing the lock button. The device used by the criminal block the signal that locks the car. Thus, thieves are able to leave the vehicle.
The crooks also use devices to amplify the signal from the key fob in order to unlock vehicles. They may even do this while the key is in the pocket of the driver or hanging from its hook in the house. Once the car has been unlocked, hackers can use an ordinary diagnosis port to program a blank fob.
Car manufacturers have come up with a variety of anti-theft solutions to safeguard against these types of attacks. However, thieves will always find ways to defeat these measures.
For instance, they've been using devices that transmit on the same radio frequency as remote key fobs in order to intercept their signals. The thieves can then copy the key fob's unlock code and then start the car using this fake signal.
This method is very popular in the US and Europe where many vehicles are sold with wireless technology that lets owners unlock and start their vehicles with a mobile app on their phone. This technique is likely to increase in popularity as more car manufacturers attempt to connect their vehicles with their owners phones.
In addition to incorporating anti-theft technology in vehicles, it's crucial for drivers to leverage best practices when parking their vehicles. They should never leave their key fobs in the ignition, should always ensure that the vehicle is locked completely when they're not using it and should make use of a steering wheel or gearstick lock if possible. It is also recommended to think about installing a tracking device on their vehicle in case it's stolen.
Flat Battery
This kind of attack is more common than people think. The thieves employ inexpensive devices that extend the signal of your key fob to unlock and start your car even in the event that it is off. Then they drive the car to a trailer or around a corner to take the car away. It is possible to protect your vehicle from this by installing an interrupter switch for the starter circuit. The most basic ones have an ON/OFF switch that interrupts the starter circuit. It costs about $15 and is simple enough to install by yourself.
Car thieves are always working on new ways to gain access to vehicles and steal them. The police as well as the car makers and insurance companies are constantly trying to catch up to their tactics and develop better anti-theft systems for modern cars. However, that doesn't stop thieves, who are able to adapt quickly and find ways to circumvent the most up-to-date anti-theft systems.
For instance, many criminals use a device that works on the same radio frequency as the fob in order to block the signal. They place the device in their pockets or somewhere near their vehicle, and it prevents the fob's lock command from reaching the vehicle and thereby leaving it unlocked. This can be done within minutes. The device is affordable and can be purchased online.
Hacking the computer system of the car is an alternative option. This is more difficult, but still feasible. Hackers have designed devices that connect to the diagnostic port of all vehicles and allow them to access the software. They can then program a blank fob to work. It is also possible to do this on older vehicles, however it is more difficult without removal website of the ignition lock.
This technique could become more popular if more vehicles are connected to drivers' phones. Once a burglar has gained the username and password to the vehicle app, they can then unlock the car or start it by using the app on their phone. You can help 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.
