Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or at their doors, they may not realize that they are allowing thieves to steal their signal. This relay attack is one of the latest techniques criminals are employing to steal new keyless vehicles.
All keyless ignition vehicles emit a low power radio signal that is used to locate an appropriate fob. If the signal can be recorded and recreated, it could be used to unlock the car and start it.
Relay Attack
Imagine your car being parked safely in the driveway, with the key fob safely inside your home. You're confident that your car is safe, but not seen by you, sophisticated thieves are plotting a heist. Instead of slamming windows or jiggling locks, they are using technology to gain access to cars through digital cracks in their armor. This is known as relay theft, it's a more common way to steal cars that have keyless entry.
Cars equipped with keyless entry are designed to operate using signals that are that is transmitted by the car's remote control (RF) transmitter to the owner's key fob. To prevent keyless entry by unauthorized individuals, the RF transmitters on the key fob as well as the car are programmed only to activate when they are within a specific distance from one another. However, a thief can overcome this limitation using an attack known as the'relay attack'.
Two people are required to do this: one stands near the car and uses a device that captures digitally the the key fob. The other, standing by the house of the owner is using a different device to send the key fob signal back down to the car. This trick tricked the car into thinking that the key fob is near enough to be able to unlock it and begin the engine.
This kind of heist was once a costly process that required expensive equipment. Today, you can purchase an inexpensive relay transmitter online and carry out a heist within minutes. This is the reason why car thieves love it.
While certain cars are less vulnerable to this type of theft than others, all cars with keyless entry are at risk. In fact researchers have examined 237 popular cars and found that they could all be stolen using this method.
Tesla vehicles are believed to be less vulnerable 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 this in the near future, however until then, they are vulnerable. That's why it's essential to be proactive about your car security and install an anti-theft kit which protects your keys as well as your the car from such attacks.
CAN Injection Attack
Modern vehicles can defend themselves against thieves by exchanging encrypted messages with the key to confirm its authenticity. The system is generally believed to be secure, but criminals have found a way to circumvent it. They impersonate the smart key, then send messages to the vehicle, and then drive off. To accomplish this, they have access to the smart keys' internal communications network.
Most cars today are equipped with between 20 and over 200 electronic control units, also known as ECUs, which control various aspects of the vehicle's operation. They communicate using the CAN bus network. These ECUs enter a low power sleep mode to reduce their power consumption. This mode is activated when the ECUs receive a "wake up" frame. These frames are typically sent via the door or smart key receiver ECU. However the messages aren't usually encrypted or authenticated, which means that they could be snatched by criminals with a cheap and simple device.
They look for a place that allows them to connect directly to the CAN connection wires. They are usually hidden inside the headlights or elsewhere in the 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 thieves then employ a device known as an CAN injection attacker to send out fake messages that fool the security systems of the car to unlock it and disable its engine immobilizer.
The devices are available on the Dark Web and work with most major car manufacturers which include 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 fix the issue in their current models. However, these thieves will continue to steal everything they can. The best we can do is to make an effort to prevent this from happening by installing mechanical security measures like Discloks on our cars, and making sure that they are always parked in well-lit areas that are clearly visible to people passing by.
Jamming the Signal
In a different variation of the relay attack, thieves may use a gadget to jam the signal sent from the key fob when the vehicle is locked. The device could be hidden in the pocket or hidden where a burglar is hiding on an open parking lot or in the driveway being targeted. Once the owners hit the lock button on their fobs, and then walk away, they don't think about whether or not their car is actually locks. The device used by the crook interferes with the signal to lock the car. Therefore, thieves could leave the vehicle.
The crooks also use devices to amplify the key fob's signals to unlock vehicles. The crooks can do this even when the key is inside a pocket of a driver, or hanging from a hook inside the home. After the car has been unlocked, they can use the standard diagnostic port or computer hackers to program a blank key fob and gain control of the vehicle.
To protect against this type of attack, car manufacturers have developed a variety of anti-theft gadgets. However, thieves will always 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 thieves copy the unlock code of the key fob and start the vehicle with this fake signal.
This method is very popular in the US and Europe where a large number of cars are equipped with wireless technology that lets owners unlock and start their vehicle using a mobile app on their smartphone. This technology will likely become more popular as more car manufacturers attempt to connect their cars to their owners smartphones.
In addition to installing anti-theft technologies in vehicles, it's crucial for drivers to use the best practices when parking their vehicles. They should not leave their keys in the ignition and should always lock the car when they are not in it. If they can it is also recommended to use a steering or gearstick locking device. They should also think about installing a tracking device to their vehicle in the event that it's stolen.
Flat Battery
This kind of attack occurs more often than people click here realize. Thieves make use of cheap devices to extend the signal from your key fob to unlock and start cars even if they're switched off. They then simply drive the car around a corner or even to a trailer and leave with it. It would be possible to protect your vehicle from this by installing an interrupter switch for the starter circuit. Simpler versions include an ON/OFF button which interrupts the circuit. It's about $15 and is simple enough to install by yourself.
Car thieves are constantly searching for new ways to rob vehicles. The police as well as car manufacturers and insurance companies are always trying to keep up to their tactics and provide better anti-theft systems for the latest cars. But this does not stop thieves who are able to easily adapt and find ways to circumvent the latest anti-theft technology.
Many thieves block the signal with devices that use the same radio frequency as the fob. The device is tucked away in the pocket or close to the vehicle, and stops the fob from transmitting the lock command to the car. This can be accomplished in a matter of minutes. The device is affordable and can be purchased online.
Hacking the computer system of the car is another option. This is more difficult, but possible. Hackers have designed devices that plug into the diagnostic port of all cars and allow them to connect to the software. They can then program an unfinished fob to work. It is possible to do this on older cars also but it's more difficult without taking out the ignition.
As more vehicles are linked to drivers' phones, this method may become more popular too. Once a criminal has the username and password to a vehicle app, they can unlock or start the vehicle with the application. You can safeguard yourself by not putting valuables inside your car, and by parking in garages.
