Cars Being Stolen With Keyless Entry
Car owners who leave keys on tables or in front of their front door could be permitting thieves to steal the signal. This relay attack is just one of the latest techniques criminals are using to steal new keyless vehicles.
Keyless ignition vehicles emit a low-power radio signal that is used to locate the fob that matches. If the signal is captured and recreated, it could be used to unlock the car and start it up.
Relay Attack
Imagine your car being parked safely in the driveway, with the key fob safely inside your home. You're sure that your car is safe, but unnoticed by you, sophisticated thieves are plotting an attack. These thieves use technology to hack into vehicles using digital chinks. This is known as relay theft, it's becoming a common way to steal cars that have keyless entry.
Cars with keyless entry are designed to operate via signals that are sent by the car's remote control (RF) transmitter to the owner's key fob. To stop unauthorized keyless entry the RF transmitters on the key fob and in the car are programmed to only activate when they're within certain distance from one another. However, thieves are able to bypass this limitation with a technique known as the'relay attack'.
To do so, two people work in tandem one is positioned by the car with a device that captures digitally the key fob's signal. The other, who is at home with the owner, 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 near enough to unlock and start it up.
This kind of heist was once a costly process that required expensive equipment. It is now possible to purchase a relay transmitter for a small price online and carry out an heist in a matter of minutes. This is the reason it's well-liked by car thieves.
All modern vehicles with keyless access 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 be targeted by this method.
Tesla vehicles are believed to be less vulnerable to this kind of theft. However Tesla hasn't implemented UWB technology to allow it to perform distance checks and stop attacks via relay. The company has said it will do so in the future, but until then they are vulnerable. That's why it's essential to take a proactive approach to your security in your car and install an anti-theft tool that safeguards your keys and the car from such attacks.
CAN Injection Attack
Modern vehicles can defend themselves from thieves by sending encrypted messages to the key in order to verify its authenticity. The system is generally believed to be secure, however criminals have found a way to circumvent it. They just impersonate the smart key and send other messages to the car letting it unlock the doors, disable its engine immobilizer, and then go on their way. To do this, they gain access to the smart keys' internal communications network.
Nowadays, the majority of cars are equipped with between 20 to 200 electronic control units (or ECUs) that control various aspects of the car's operation. They communicate with one another using 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 are typically sent via the door or smart key receiver ECU. These messages are not always authenticated or encrypted. This means that criminals can 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 hide in the headlights or in other areas of the front of the vehicle. To gain access to them, you can pull the bumper and cut holes in the headlamp assemblies. The thieves use the device referred to as an CAN injection attack to send fake messages that fool the safety systems of the car to unlock and disable the engine immobilizer.
These devices can be purchased through the Dark Web and work with most major car manufacturers including BMW and Cadillac, check here 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 fix it in their existing models, but the reality is that these thieves will continue to steal whatever they can get their hands on. We can prevent this by installing mechanical security measures, such as Discloks inside all of our cars and parking them in well-lit, visible areas.
Jamming the Signal
In a different variant of the relay attack, thieves could employ a device to block the signal from a key fob when the car is locked. The device could be in the pocket of a burglar in a parking area or in a hidden spot close to the driveway that is being targeted. The owners don't know whether their vehicle is locked when they press the lock button. The device used by the crook block the signal that locks the car. Therefore, thieves can drive away with the vehicle.
The crooks also use devices to enhance the signal of the key fob to unlock vehicles. The crooks can accomplish this even when the key is in the pocket of a driver, or hanging on an outside hook in the home. After the car is unlocked, hackers can use the standard diagnostic port to program the fob with a blank.
Car manufacturers have come up with various anti-theft devices to protect against these types of attacks. 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 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 and Europe where a large number of vehicles are sold with wireless technology that lets owners unlock and start their vehicles using a mobile app on their smartphone. This technology will likely become more popular as more companies attempt to connect their vehicles with their owners' smartphones.
In addition to installing anti-theft technologies in vehicles, it's vital for drivers to leverage best practices when they park their vehicles. It is not advisable to leave their keys in the ignition and always secure the car when not in it. If they can, they should also use the gearstick or steering locking device. They should also think about installing a tracking device to their vehicle in the event that it gets stolen.
Flat Battery
This type of attack occurs more often than most people realize. Thieves employ cheap devices to extend the signal from your key fob to unlock and start cars even if they're turned off. They then drive the car around the corner or to a trailer and then drive off with it. It is 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 costs around $15 and is simple to install.
Car thieves are always looking for new ways to rob vehicles. The police as well as the car makers and insurance companies are always trying to catch up with their tactics and develop better anti-theft systems for the latest cars. However, that doesn't stop thieves who are able adapt quickly and discover ways to bypass the most up-to-date anti-theft systems.
Many thieves block the signal with devices that operate on the same radio frequency as the fob. The device is put in the pocket or near the vehicle, and stops the fob from transmitting the lock command to the vehicle. This can be accomplished in just a few seconds. The device is cheap and can be purchased online.
Another strategy is to hack the car's computer system. This is more difficult but possible. All cars have an diagnostic port, and hackers have created devices that connect to them and let them access the software of the car. From there, they are able to program the blank key fob to make it work. It is possible to do this on older cars as well however it is more difficult if you remove the ignition.
This technique could become more popular if more vehicles are connected to drivers' mobile phones. Once a thief gets the username and password for an app for vehicles they are able to open the car or get it started with the app on their phone. You can safeguard yourself by not putting valuables in your car and also by parking in garages.
