Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or near their doors, they could unknowingly be allowing thieves to steal their signal. This relay attack is just one of the high-tech methods criminals are using to steal brand new keys from cars.
Keyless ignition vehicles emit a low-power radio signal looking for a matching fob to respond. If the signal can be captured and recreated, it could be used to unlock the car, and also to start it.
Relay Attack
Imagine your car safely parked in the driveway, and the key fob sitting safely in your home. You may think your car is secure, but sophisticated thieves are planning to steal your car without you being aware. Instead of slamming windows and jiggling locks, these thieves are using technology to gain access to cars through digital cracks in their armor. This is known as relay theft, it's an increasingly common way to steal cars with keyless entry.
The keyless entry system in cars is controlled by a signal sent from the car's RF transmitter to the key fob. To prevent unauthorized keyless entry the RF transmitters on the key fob as well as in the car are programmed to activate only when they're within a specific distance from each other. However, thieves are able to overcome this limitation using a technique known as the'relay attack'.
Two people are required to complete this: one person is close to the car and utilizes a device to capture an electronic version of the signal from the key fob. The other, who is at the home of the owner, uses a second gadget to transmit the signal from the key fob back to the car. This trickery fools the car into thinking the key fob is near enough to unlock and start the engine.
In the past, this type of heist required expensive equipment in order to execute. It is now possible to purchase a cheap relay transmitter online and pull off an heist in a matter of minutes. This is why it's popular with car thieves.
While certain cars are less prone to this type of theft than others, all cars with keyless entry are at risk. Researchers have tested 237 popular cars and found that every one of them could be taken through this method.
Tesla cars are said to be less susceptible to this type of theft, however the company has not yet implemented UWB features that could effectively conduct distance checks on the car's signal to stop relay attacks. The company has said that they will implement this in the future but until then they are vulnerable. Installing an anti-theft device that protects both your keys and your car against such a threat is a proactive method to ensure the security of your vehicle.
CAN Injection Attack
Modern cars can protect themselves against thieves by transferring encrypted messages using the key to confirm its authenticity. This system is generally reckoned to be secure, but thieves have found a way to circumvent it. They impersonate a smart key, send messages to the vehicle and then drive off. To achieve this, they need 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) which control different aspects of the car's operation. They communicate with one another using an electronic network referred to as CAN bus. These ECUs enter a low power sleep mode to lower their power consumption. This mode is activated when ECUs receive a "wake up" frame. These frames are usually sent by the ECU that controls the smart key or door. These messages are not always authenticated or encrypted. This means that criminals can capture them using an inexpensive and simple device.
To accomplish this, they must look for a spot that allows them to connect directly to the CAN bus connection wires. They usually are hidden in the headlights or in other places in the front of the vehicle. To gain access to them, you can remove the bumper and cut holes in the headlamp assemblies. The thieves then use a device called a CAN injection attacker to send fake messages that can trick the car's security systems into unlocking it and disengaging the engine immobilizer.
The 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 more. The researchers who discovered this CAN Injection attack are recommending that all car makers address it in their existing models, but the fact is that thieves will continue to grab everything they can lay their hands on. The best thing we can do is make an effort to prevent this from happening by putting in mechanical security measures like Discloks on all our cars, and making sure that they're always placed in areas that are well-lit and are clearly visible to people passing by.
Blocking website the Signal
In a variant of the relay attack, which makes use of a device that is able to block the signal transmitted by key fobs while the vehicle is locked. The device could be in the pocket of a thief in a parking space or in a hiding spot close to the driveway that is being targeted. Once the owners hit the lock button on their fobs and walk away they don't consider whether or not their car is really locked. The device used by the criminal interferes with the signal to lock the car. Therefore, thieves can escape with the car.
They also use devices that amplify signals from the key fob to unlock vehicles. The crooks are able to do this even if the key is in the driver's pocket or hanging on a hook inside the home. When the car is unlocked, they can make use of the standard diagnostic port or computer hacker to program the blank key fob and gain control of the vehicle.
To protect against this type of attack, car manufacturers have created a variety of anti-theft devices. But, as always, thieves come up with ways to thwart these measures.
They've been using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The crooks then copy the unlock code from the key fob and begin the vehicle using this fake signal.
This method is particularly popular in the US and Europe where many cars are equipped with wireless technology that allows owners to unlock and start their vehicles with a mobile app on their smartphone. This technique is likely to be more commonplace as more manufacturers try to link their cars with their owners phones.
In addition to implementing anti-theft systems in vehicles, it's vital for drivers to leverage best practices when they park their vehicles. They should never leave their key fobs in the ignition, should always make sure the vehicle is locked completely when they're not there and should use a steering wheel or gearstick lock, if they can. They should also think about installing a tracking device to their vehicle in the event that it is stolen.
Flat Battery
This type of attack occurs more often than we think. The thieves use inexpensive devices that extend the signal of your key fob to enable it to unlock and start your car when it's off. Then they drive the vehicle to the trailer or around a corner, and take the vehicle away. It would be possible to protect your vehicle from this by installing an interrupter switch for the starter circuit. The simplest ones just have an ON/OFF switch that interrupts the starter circuit. It costs around $15 and is easy to install.
Car thieves are always working on new ways to get into vehicles and steal them. The police as well as car manufacturers and insurance companies are always trying to catch up to their tactics and develop better anti-theft systems for the latest 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 example, many criminals use a device that works on the same frequency as the fob 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 within seconds. The device is affordable and can be purchased online.
Hacking the computer system of the car is another option. This is harder but still possible. Hackers have created devices that plug into the diagnostic port of all vehicles and allow them to connect to the software. They can then program an unfinished fob to work. This can also be done on older vehicles, but it is more difficult to do so without removal of the ignition lock.
This method is likely to be more popular if more vehicles are connected to drivers' mobile phones. Once a burglar has access to the username and password to a vehicle application they can open or start the vehicle by using the app. You can guard yourself by not leaving valuables inside your car, and also by parking in a garage.
