Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or near their door, they may unknowingly allow thieves to hijack their signal. This relay attack is a sophisticated method criminals use to steal keys from new vehicles.
Keyless ignition vehicles emit a low-power radio signal to locate a matching fob. If the signal can be captured and recreated, it could be used unlock the car and to start it.
Relay Attack
Imagine your car in your driveway, and your key fob inside your home. You may be confident that your vehicle is secure but sophisticated thieves are planning a heist without you being aware. Instead of slamming windows or jiggling locks, they are using technology to hack into cars via digital cracks in their armor. Known as relay theft, it's an increasingly common way to steal cars with keyless entry.
The keyless entry system found in cars is controlled by a signal sent from the car's RF transmitter to the key fob. To stop keyless entry by intruders the RF transmitters that are on the key fob as well as the car are programmed only to turn on when they are within a specific distance of each other. A thief, however, can bypass this restriction by employing a technique called the "relay-attack".
To do so two people work together One stands near the car, using an instrument that records digitally the key fob's signal. The other, standing by the house of the owner is using a different device to transmit 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 the engine.
This kind of heist was once a costly process that required expensive equipment. However, now you can purchase relay transmitters on the low cost online and conduct a heist in minutes. This is why car thieves are enthralled by it.
While certain vehicles are less vulnerable to this type of theft than others, all modern cars with keyless entry are at risk. Researchers have tested 237 of the most popular automobiles and found that all of them can be stolen by this method.
Tesla vehicles are believed to be less vulnerable to this kind of theft. However Tesla hasn't yet implemented UWB technology to allow it to conduct distance checks and prevent relay attacks. The company has stated that they will do this in the near future, but until then, they are vulnerable. Installing an anti-theft system that protects both your car keys and your keys against such attacks is a proactive way to ensure your car's security.
CAN Injection Attack
Modern vehicles can defend themselves from theft by transferring encrypted messages using the key in order to verify its authenticity. The system is thought to be secure, but thieves have found ways to get around it. They fake the identity of a smart key, transmit messages to the vehicle, and then drive off. To do this they have access to the smart key's internal communication network.
Most cars today are equipped with between 20 and over 200 electronic control units, or ECUs, that control different aspects of the vehicle's operation. They communicate using an electronic network known as CAN bus. To keep power consumption low, these ECUs go into a low-power sleep mode that's activated when they receive a wake up frame. These frames are usually sent by the ECU that controls the smart key or door. However, these messages aren't always authenticated or encrypted so they can be intercepted by criminals who have a low-cost and simple device.
To do this, they look for a location where they can connect directly to the CAN bus wires. They are usually hidden in the headlights, or in other areas of the front of the vehicle. To access them, you must remove the bumper and make holes in the headlamp assemblies. The thieves employ the device referred to 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 on the Dark Web and work with the majority of major car manufacturers including 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 this issue in their existing models. However, the thieves will continue to steal everything they can. We can stop this from happening by installing mechanical safety measures such as Discloks in all of our cars and parking them in well-lit, well-lit areas.
The Signal is blocked
In a different variation of the relay attack, thieves can employ a device to block the signal from a key fob when the car is locked. The device could be found in the pocket or hiding place of a thief on the parking lot, or near the driveway that is being targeted. Once the owners press the button to lock their fobs, and then walk away and leave, they don't have to think about whether or not the car really is locked. Instead, thieves are able to escape with the vehicle since the signal that normally locks the car is blocked by the crook's device.
The crooks also make use of devices to amplify the signal from the key fob to unlock vehicles. The crooks can accomplish this even if the key is inside a driver's pocket or hanging on an outside hook in the home. Once the car has been unlocked, hackers can make use of an ordinary diagnosis port to program a blank fob.
To guard against this kind of attack, car makers have developed a variety of anti-theft gadgets. But, as always, thieves come up with ways to thwart these measures.
For instance, they've been using devices that transmit on the same radio frequency as remote key fobs to intercept their signals. The crooks then copy the unlock code of the key fob, and then start the vehicle with this fake signal.
This method is particularly popular in the US and Europe where a large number of automobiles are sold with wireless technology that allows owners to unlock and start their vehicles using a mobile app from their phones. This technology is likely to become more popular as more and more car manufacturers attempt to connect their vehicles with their owner's smartphones.
In addition to installing anti-theft technologies in vehicles, it's vital for drivers to use the best practices when parking their vehicles. They should never leave the keys in ignition and secure the car when they are not in it. If possible they should also utilize a steering or gearstick locking device. They should also consider fitting a tracking device to their vehicle in case it's stolen.
Flat Battery
This type of attack is more common than most people realize. The thieves employ low-cost devices that increase the signal from your key fob in order to unlock and start your car, even when it's off. They then simply drive the car around the corner or onto a trailer to take off with it. Installing an interrupter switch for the starter circuit will protect your vehicle from this. The simplest ones just have an ON/OFF switch which interrupts the starter circuit. It costs more info around $15 and is easy to install.
Car thieves are always working on new ways to gain access to vehicles and steal them. The police, car makers and insurance companies are constantly trying to catch up with their strategies and provide better anti-theft systems for modern cars. However, that doesn't stop thieves who are able to be quick to adapt and find ways to circumvent the most recent anti-theft measures.
Many thieves jam the signal by using devices that operate on the same radio frequency of the fob. The device is tucked away in the pocket or near the vehicle and prevents the fob from transmitting the lock command to the car. This can be done within just a few seconds. The device is affordable and available on the internet.
Hacking the computer system of the car is another option. This is more difficult but it is still feasible. All cars have a diagnostic port, and hackers have created devices that plug into them and allow them access the software in the car. From there, they can program an unfinished key fob and make it work. It is also possible to do this on older cars, although it is more difficult without taking off the ignition lock.
As more vehicles are connected to smartphones of drivers the method is likely to become more popular as well. Once a burglar has gained the username and password for a vehicle app they are able to open the car or get it started by using the app on their phone. You can help be safe from these kinds of attacks by not leaving valuables in your car, and then parking it in a garage or secured parking lot.
