Cars Being Stolen With Keyless Entry
Car owners who toss keys on tables or near their front door may be unwittingly allowing thieves to hijack the signal. This relay attack is a highly-tech method criminals use to steal new keyless vehicles.
Keyless ignition vehicles emit a low power radio signal that is used to locate a matching fob. If the signal can be recorded and recreated, it could be used unlock the car and start it.
Relay Attack
Imagine your car being parked safely in your driveway, with the key fob sitting safely in your home. You're sure that your car is safe, but not seen by you, sophisticated thieves are plotting an attack. Instead of slamming windows or jiggling locks, thieves are using technology to hack into cars via digital chinks in their armor. Known as relay theft, it's an increasingly common method of stealing vehicles that have keyless entry.
Cars with keyless entry are designed to operate using a signal sent from the car's remote control (RF) transmitter to the owner's key fob. To stop unauthorized keyless entry, the RF transmitters in the key fob as well as in the car are programmed to activate only when they're within a specific distance from one another. The thief can circumvent this limitation employing a technique called the'relay-attack'.
Two people are required to complete this: one person is near the car and utilizes a device to capture a digitalized version of the signal from the key fob. The other person who is at the home of the owner and uses a different device to transmit the signal from the key fob to the car. This trickery fools the car into thinking the key fob is near enough to be able to unlock it and start it up.
This kind of heist used to require expensive equipment. Today, you can purchase a relay transmitter for a small price online and pull off an heist in a matter of minutes. This is the reason car thieves love it.
While certain cars are less vulnerable to this kind of theft than others, all modern vehicles that have keyless entry are at risk. Researchers have examined 237 well-known cars and found that all of them are susceptible to being stolen using this method.
Tesla vehicles are supposedly less prone to this kind of theft, however, the company hasn't yet implemented UWB features that would effectively perform distance checks on the car's signal and prevent relay attacks. The company has promised to make this happen in the near future, but until then, they remain vulnerable. Installing an anti-theft system that protects both your car and your keys against such attacks is a proactive approach to ensure the security of your vehicle.
CAN Injection Attack
Modern cars are designed to guard themselves from thieves by exchanging cryptographic data with the key to prove it's genuine. The system is believed to be secure, but criminals have found ways to circumvent it. They simply pretend to be the smart key and send other messages to the car, letting it unlock the doors, turn off its engine immobilizer, and let them 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 and 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate using a network called CAN bus. To keep power consumption low the ECUs enter a low-power sleep mode that's activated when they receive a 'wake up' frame. These frames are typically sent through the door or a smart key receiver ECU. These messages are not always encrypted or authenticated. This means that criminals are able to intercept them with the use of a cheap and simple device.
To accomplish this, they must look for a location where they can connect directly to the CAN bus wires. They usually hide in the headlights or in other locations in the front of the vehicle. To get them, you need to pull the bumper and cut holes in the headlamp assemblies. The thieves employ an instrument known as an CAN injection attack. It is used to send fake messages that fool the safety systems of the car into unlocking and disengaging the engine immobilizer.
The devices are available for sale on the Dark Web, and work for the majority of major car manufacturers, including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and more. Researchers who discovered the CAN Injection attack recommend that all car manufacturers fix the issue in their current models. However, these thieves will continue to take everything they can. We can prevent this by implementing mechanical safety measures such as Discloks in all of our cars and parking them in well-lit, visible areas.
Jamming the Signal
In a variant of the relay attack that makes use of a device that can be used to block the signal sent by the key fob when the car is locked. The device could be in the pocket or hiding the location of a thief in an open parking lot or in the driveway being targeted. The owners don't know if the vehicle is locked after pressing the lock button. Instead, thieves could escape with the vehicle because the signal that normally locks the car has been blocked by the device of the criminal.
The crooks also employ devices to amplify the signal from the key fob to unlock vehicles. The crooks are able to do this even when the key is inside a driver's pocket or hanging on an outside hook in the home. When the car is unlocked, they can make use of a standard diagnostic port or computer hacker to program the blank key fob and gain control over the vehicle.
Automobile manufacturers have developed a range of anti-theft systems to guard against these kinds of attacks. But thieves always find ways to defeat these measures.
They've been using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The thieves can then copy the key fob's unlock code and start the car with this fake signal.
This method is very popular in the US and Europe where a lot of automobiles are sold with wireless technology that lets owners unlock and start their vehicle using a mobile app from their phones. This technology will likely become more popular as more companies attempt to link their cars with their owners' smartphones.
It is essential that drivers follow the best click here practices when parking their vehicles. It is not a good idea to leave keys in the ignition. They should always ensure that their car is fully locked when they're not in it and should make use of an engine or steering wheel lock, if it is possible. They should also think about installing a tracking device to their car in the event it gets stolen.
Flat Battery
This kind of attack occurs more often than we think. Thieves make use of inexpensive devices to extend the signal from your key fob to unlock and start cars even if they're switched off. They then drive the car around the corner or to a trailer and leave with it. Installing an interruption switch to the starter circuit will protect your vehicle from this. The simplest ones are an ON/OFF switch which interrupts the starter circuit. It's about $15 and is simple to put in yourself.
Car thieves are always searching for new ways to steal vehicles. The police as well as car manufacturers 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 adapt quickly and discover ways to bypass the most recent anti-theft measures.
A lot of thieves block the signal with devices that operate on the same radio frequency as the fob. They place the device in their pocket or in a location 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 in a matter of seconds. The device is affordable and available on the internet.
Hacking the computer system of the car is another option. This is harder but still possible. Every car has a diagnostic port, and hackers have designed devices that plug into them and let them access the car's software. They can then program the fob with blank code to function. It is also possible to do this on older vehicles, however it is more difficult to do without removal of the ignition lock.
This method could become more popular as more vehicles are connected with drivers' mobile phones. Once a burglar has the username and password to a vehicle application they can open or start the vehicle with the app. You can guard yourself by not leaving valuables inside your car, and also by parking in garages.
