Cars Being Stolen With Keyless Entry
Car owners who toss their keys on tables or in front of their front door may be unwittingly allowing thieves to hijack the signal. This relay attack is one of the latest techniques criminals are employing to steal new keyless vehicles.
All keyless ignition cars emit an low-power radio signal that is looking for a matching fob that can respond. If the signal is recorded and recreated it can be used to unlock the car and start it up.
Relay Attack
Imagine your car safely in your driveway, and your key fob in 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 method of stealing vehicles with keyless access is called relay theft.
Cars equipped with keyless entry are designed to operate via an electronic signal that is sent from the remote control (RF) transmitter to the owner's key fob. To ensure that keyless entry is not unauthorized the RF transmitters on the key fob and car are programmed to only activate when they're within certain distance of each other. However, thieves are able to overcome this limitation using an attack known as the'relay attack'.
Two people are required to do this: one person is near the car and uses a device that captures an electronic version of the signal coming from the key fob. The other, in the vicinity of the house of the owner and using a second 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 start it up.
In the past, this type of attack required expensive equipment to carry out. However, now you can purchase relay transmitters for inexpensive online market and carry out a heist in minutes. This is the reason car thieves are enthralled by it.
While some cars are less susceptible to this type of theft than others, all modern cars with keyless entry are vulnerable. In fact, researchers have tested 237 vehicles that are popular and found that they can all be stolen using this method.
Tesla vehicles are believed to be less prone to this kind of theft. However Tesla hasn't implemented UWB technology to enable it to perform distance checks and prevent relay attacks. The company has promised to do so in the future, but until then, they remain vulnerable. Installing an anti-theft system that safeguards your car and your keys against these types of attacks is a proactive way to ensure the security of your car.
CAN Injection Attack
Modern vehicles can defend themselves against thieves by exchanging encrypted messages with the key to verify its authenticity. The system is generally believed to be secure, but criminals have found a way around it. They just impersonate the smart key and send other messages to the vehicle letting it unlock the doors, turn off its engine immobilizer, and then leave the car. To accomplish this, they have access to the smart keys' internal communications network.
Today, most cars are equipped with between 20 to 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate via the CAN bus network. These ECUs enter a low power sleep mode to decrease their power consumption. This mode is activated when ECUs receive an "wake up" frame. These frames typically come through the door or a smart key receiver ECU. These messages aren't always encrypted or authenticated. This means that thieves can capture them using the use of a cheap and simple device.
They look for a place that allows them to connect directly to the wires of the CAN connection. They're usually hidden inside the headlights or elsewhere in the front of the car and are accessible by pulling the bumper off 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 that can trick the car's security systems into unlocking the car and disengaging its engine immobilizer.
These devices are available for sale on the Dark Web, and work for the majority of 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 manufacturers fix the issue in their current models, but the fact is that thieves will continue to grab anything they can get their hands on. The best thing we can do is attempt to stop this from happening by putting in mechanical security measures such as Discloks on all of our cars, and making sure that they are placed in areas that are well-lit and are clearly visible to people passing by.
Blocking the Signal
In a variant different to the relay attack, thieves could make use of a device to block the signal sent from a key fob when the vehicle is locked. The device could be in the pocket or hidden the location of a thief in a parking lot, or near the driveway that is being targeted. The owners don't know if the vehicle is locked after pressing the lock button. The device used by the criminal interferes with the signal to lock the car. Thus, thieves are able to leave the vehicle.
They also use devices that amplify signals from the key fob to unlock vehicles. The crooks can do this even when the key is inside a driver's pocket or hanging on an outside hook in the home. After the car is locked, hackers can use the standard diagnostic port to program a blank fob.
To safeguard against this kind of attack, car manufacturers have developed a variety of anti-theft devices. But, thieves are constantly finding ways to beat these measures.
For example, they've started using devices that transmit on the same radio frequency as remote key fobs in order to intercept their signals. The crooks can then copy the key fob's unlock code and then start the car with this fake signal.
This method is particularly popular in the US where a lot of cars have wireless technology. Owners can start and unlock their car using a mobile application on their phone. This technology will likely increase in popularity as more companies attempt to link their cars with their owners smartphones.
In addition to implementing anti-theft systems in vehicles, it's vital for drivers to follow the best practices when they park their vehicles. They should never leave their keys in the ignition. They should always make sure the car is securely locked when they're not using it and should use an engine or steering wheel lock, if it is possible. It is also recommended to think about fitting a tracking device to their vehicle in the event that it's stolen.
Flat Battery
This type of attack occurs more often than people realize. The thieves make use of low-cost devices that increase the signal of your key fob in order to unlock and start your car if it is off. Then they drive the vehicle to a trailer or around a corner and take the car away. Installing an interrupter switch for the starter circuit would protect your car against this. The most basic ones have an ON/OFF switch which interrupts the starter circuit. It's priced at around $15 and is easy enough to install yourself.
Car thieves are always looking for new ways to get into vehicles and then steal them. The police as well as car manufacturers and insurance companies are always trying to catch up with their tactics and provide better anti-theft systems for modern vehicles. But this isn't stopping thieves who easily adapt and find ways to circumvent the latest anti-theft technology.
For example, many thieves 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 pocket or near their vehicle, and it prevents the fob's lock signal from reaching the vehicle, leaving it unlocked. This can be done within just a few seconds. The device is inexpensive and easily accessible online.
Hacking the computer system of the car is an alternative option. This is more difficult, but still possible. Hackers have developed devices that plug into the diagnostic port of all cars and allow them to access the software. They can then program an unfinished fob to function. This is also possible on older vehicles, but it is more difficult without taking off the ignition lock.
As more vehicles are linked to smartphones of drivers and this method could become more popular too. Once a burglar has access to the username and password to an application for vehicles and is able to unlock or start the vehicle website with the app. You can safeguard yourself by not putting valuables inside your car, and parking in garages.
