Cars Being Stolen With Keyless Entry
If car owners throw their keys on the table or next to 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 new keyless cars.
Keyless ignition vehicles emit a low-power radio signal that is used to locate the fob that matches. If the signal is recorded and recreated, it can be used to unlock the car and begin it up.
Relay Attack
Imagine your car safely parked in the driveway, and the key fob sitting safely in your home. You're sure that your car is safe, but unnoticed by you, sophisticated thieves are plotting a heist. Instead of slamming windows or jiggling locks, these thieves are leveraging technology to hack into cars via digital chinks in their armor. Known as relay theft, it's a more common method of stealing vehicles that have keyless entry.
Cars equipped with keyless entry are designed to operate via a signal sent from the car's remote control (RF) transmitter to the owner's key fob. To stop keyless entry by unauthorized individuals, the RF transmitters on the key fob as well as the car are programmed to be activated when they are within a specified distance from one another. However, thieves are able to override this restriction using a technique known as the'relay attack'.
Two people are required to complete this: one stands close to the car and uses a device that captures a digitalized version of the the key fob. The other who is at home with the owner, uses a second gadget to transmit the signal from the key fob to the car. This trickery tricks the car into believing that the key fob is at an adequate distance to allow the vehicle to start and unlock. vehicle.
This kind of heist was once a costly process that required expensive equipment. But now, you can purchase relay transmitters for inexpensive online market and carry out the heist in just a few minutes. This is the reason why car thieves are enthralled by it.
While certain vehicles are less susceptible to this kind of theft than others, all cars with keyless entry are vulnerable. Researchers have tested 237 of the most popular cars and found that every one of them can be stolen by this method.
Tesla vehicles are said to be less prone to this kind of theft. However, the company hasn't yet implemented UWB technology to allow it to conduct distance checks and prevent attacks via relay. The company has stated that they will make this happen in the near future, but until then, they remain vulnerable. That's why it's essential to be proactive about your car security and install an anti-theft kit that protects your keys and the car from such attacks.
CAN Injection Attack
Modern cars are designed to protect themselves from theft by exchanging cryptographic messages with the key to prove it's authentic. The system is generally believed to be secure, but thieves have found a way to circumvent it. They can impersonate the smart key, and send other messages to the car letting it unlock the doors, turn off its engine immobilizer, and let them leave the car. To do that they gain access to the smart key's internal communication network.
Today, most automobiles are equipped with between 20 and 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 reduce their power consumption. This mode is activated when the ECUs receive an "wake up" frame. These frames are usually sent by the ECU that manages the smart key or door. However the messages aren't usually encrypted or authenticated and, therefore, could be snatched by criminals using a cheap and basic device.
They search for a spot that allows them to connect directly to the wires of the CAN connection. They usually hide in the headlights or in other areas of the front of the vehicle. To get them, you must pull the bumper and cut holes in the headlamp assemblies. The thieves use the device referred to as a CAN injection attack to send fake messages that can trick the security systems of the car to unlock and disable the engine immobilizer.
These devices are for purchase on the Dark Web, and work for most of the major car manufacturers which include BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and many more. The researchers who discovered this CAN Injection attack are recommending that all car makers address the issue in their current models, but the reality is that these thieves will continue to grab anything they can get their hands on. We can prevent this by installing mechanical safety measures like Discloks in all of our cars and parking them in well-lit, well-lit areas.
Blocking the Signal
In a different variant of the relay attack, thieves can use a gadget to jam the signal sent from a key fob when the car is locked. The device could be found in the pocket or hidden place of a thief on an open parking lot or in the driveway being targeted. Once the owners press the button to lock their fobs, and then walk away, they don't think about whether or not their car is actually locks. The device used by the criminal interferes with the signal to lock the vehicle. Therefore, thieves can leave the vehicle.
The crooks also make use of devices to enhance the signal of the key fob to unlock vehicles. They can accomplish this if the key is in the driver's pocket or hanging from its hook in the home. Once the car has been locked, hackers can use a standard diagnosis port to create an unlocked fob.
To safeguard against this kind of attack, car makers have developed a variety of anti-theft devices. However, thieves are always trying to beat 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 thieves then copy the unlock code of the key fob, and then start the vehicle using this fake signal.
This method is very popular in the US and Europe where a lot of automobiles are sold with wireless technology that allows owners to unlock and start their vehicle by using a mobile application on their smartphone. This technique is likely to increase in popularity as more manufacturers try to connect their vehicles with their owners smartphones.
It is crucial that drivers use best practices when parking their vehicles. They shouldn't leave their key fobs in the ignition, should always ensure that their car is securely locked when they're not in it and should make more info use of the steering wheel or a gearstick lock, if it is possible. It is also recommended to think about installing a tracking device onto their vehicle in case it is stolen.
Flat Battery
This kind of attack happens more often than people realize. Thieves make use of cheap devices to extend the signal from your key fob to unlock and begin cars even if they're turned off. Then they drive the car to the trailer or around a corner, and take the car away. Installing a starter circuit interruption switch can protect your vehicle from this. Simpler versions have an ON/OFF button which interrupts the circuit. It's about $15 and is simple to put in yourself.
Car thieves are constantly looking for new ways to take vehicles. The police as well as the car makers and insurance companies are constantly trying to keep up with their strategies and provide better anti-theft systems for modern vehicles. But that doesn't stop the thieves who are able to be quick to adapt and find ways to circumvent the latest anti-theft measures.
Many thieves block the signal using devices that use the same radio frequency as the fob. They place the device in their pocket or close to their vehicle, and it stops the fob's lock commands from reaching the vehicle which leaves the vehicle unlocked. This can be done in minutes. The device is cheap and easily accessible online.
Hacking the computer system of the car is an alternative option. This is more difficult, but still possible. All cars have a diagnostic port, and hackers have created devices that plug into them and allow them access the car's software. From there, they can program a blank key fob and make it work. It is possible to do this on older vehicles too, but it's more difficult if you remove the ignition.
As more vehicles are connected to smartphones of drivers, this method may become more popular too. Once a thief has access to the username and password to a vehicle application, they can unlock or start the vehicle using the app. Fortunately, you can be safe from these kinds of attacks by not putting valuables in your car, and then parking it in a garage or secured parking lot.
