If car owners throw their keys on the table or at their doors, they could not realize that they are allowing thieves to hijack their signal. This relay attack is one of the latest techniques criminals are using to steal new keyless cars.
All keyless entry cars stolen ignition cars emit an low-power radio signal that is seeking a compatible fob to respond. If the signal is captured and recreated, it can be used to unlock the car and then start it up.
Relay Attack
Imagine your car safely parked in your driveway with your key fob in your home. You're confident that your car is safe, but not seen by you sophisticated thieves are planning an heist. Instead of breaking windows or jimmying locks, thieves are leveraging technology to gain access to cars through digital chinks in their armor. This method of stealing cars with keyless access is known as relay theft.
Cars equipped with keyless entry are designed to operate via an electronic signal that is sent by the car's remote control (RF) transmitter to the owner's key fob. To ensure that keyless entry is not accessed by unauthorized individuals the RF transmitters on the key fob and the car are programmed to be activated when they are within a certain distance from each other. However, thieves can circumvent 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 uses a device to capture digitally the the key fob. The other, in the vicinity of the home of the owner and using a second device to transmit the key fob signal back down to the car. This trickery fools the car stolen with keys from house into thinking that the key fob is close enough to be able to unlock it and start it up.
In the past, this kind of attack required expensive equipment to perform. Now, you can buy a relay transmitter on the cheap online and execute the heist in just a few minutes. This is why it's so well-liked by car thieves.
While certain vehicles are less susceptible to this type of theft than others, all cars with keyless entry are at risk. Researchers have tested 237 of the most popular automobiles and found that all of them are susceptible to being stolen through this method.
Tesla vehicles are said to be less susceptible to this kind of theft. However Tesla hasn't yet implemented UWB technologies that would allow it to perform distance checks and prevent attacks via relay. The company has said it will make this happen in the near future, but until then, they remain vulnerable. That is why it's important to adopt a proactive approach to your vehicle security and install an anti-theft device which protects your keys as well as your car from these types of attacks.
CAN Injection Attack
Modern vehicles can defend themselves from thieves by exchanging encrypted messages with the key to confirm its authenticity. This method is generally thought to be secure, but thieves have found a way to circumvent it. They impersonate a smart key, transmit messages to the vehicle and then drive away. To achieve this, they need access to the smart my keys were stolen' internal communications network.
The majority of cars today are fitted with between 20 and 200 electronic control units, or ECUs, that control different aspects of the vehicle's operation. They communicate with one another using an electronic network referred to as CAN bus. To ensure that power consumption is low they ECUs enter sleep mode with low power that is activated when they receive a wake up frame. These frames are usually sent by the ECU that is in charge of the smart key or door. However the messages aren't usually encrypted or authenticated so they could be snatched by criminals using a cheap and simple device.
They look for a place where they can connect directly to the wires for CAN connection. They usually are hidden in the headlights, or in other areas of the front of the vehicle. To gain access to them, you need to remove the bumper and make holes in the headlamp assemblies. The thieves then employ a device dubbed an CAN injection attacker to send fake messages which trick the car's security systems to unlock it and disable the engine immobilizer.
These devices are for purchase on the Dark Web, and work for most of the major car manufacturers 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 it in their existing models, but the fact is that the thieves will continue to take everything they can lay their hands on. We can stop this from happening by implementing mechanical safety measures like Discloks in all our vehicles and parking them in well-lit, well-lit areas.
The Signal is blocked
In a different variant of the relay attack, thieves could make use of a device to block the signal that is sent by the key fob when the car is locked. The device could be hidden in the pocket or hiding where a burglar is hiding on the parking lot, or in the driveway being targeted. Once owners hit the lock button on their fobs and leave and leave, they don't have to think about whether or not the car is really locked. Instead, thieves could drive off with the vehicle because the signal that normally locks the car is blocked by the device of the criminal.
They also have 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 from a hook inside the home. When the car is unlocked, they can make use of an ordinary computer hacker to program the blank key fob and gain control of the vehicle.
Car manufacturers have developed a range of anti-theft systems to protect against these types of attacks. But, as always, thieves find ways to defeat these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs to intercept signals. The crooks then copy the unlock code from the key fob, and then start the vehicle using this fake signal.
This method is very popular in the US and Europe where a large number of automobiles are equipped with wireless technology that allows owners what to do if car key is stolen unlock and start their vehicles by using a mobile application on their smartphone. This technology is likely to become more popular as more and more manufacturers attempt to link their vehicles to their owners' smartphones.
In addition to incorporating anti-theft technology in vehicles, it's vital for drivers to use the best practices when they park their vehicles. They should never leave their key fobs in the ignition, 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 possible. They should also consider installing a tracking device on their vehicle in the event that it's stolen.
Flat Battery
This type of attack is more prevalent than many people believe. The thieves employ cheap devices that extend the signal from your key fob in order to unlock and start your car key stolen from house, even when it's off. They then simply drive the car around a corner or to a trailer and then drive off with it. Installing an interruption switch to the starter circuit would protect your car against this. The simplest ones are an ON/OFF switch which interrupts the starter circuit. It costs about $15 and is simple to install yourself.
Car thieves are constantly seeking new ways to take 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 modern cars. But that doesn't stop the thieves who are able change quickly and discover ways to bypass the most up-to-date anti-theft systems.
A lot of thieves block the signal with devices that use the same radio frequency of the fob. They put the device in their pockets or in a location close to their vehicle, and it stops the fob's lock signal from reaching the car which leaves it unlocked. This can be done in just a few seconds. The device is affordable and available online.
Hacking the computer system of the car is an alternative option. This is more difficult, but nevertheless feasible. Hackers have designed devices that plug into the diagnostic port of all vehicles and permit them to connect to the software. From there, they are able to program the blank key fob to start working. This is also possible on older cars, although it is more difficult to do so without removing the ignition lock.
This method is likely to become more popular as 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 help be safe from these kinds of attacks by not putting valuables in your car and parking it in a garage or secured parking lot.
