Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or at their doors, they may not realize that they are allowing thieves to hijack their signal. This relay attack is a high-tech technique used by criminals to steal keyless vehicles.
All keyless ignition cars emit a low-power radio signal seeking a compatible fob that can respond. If the signal is recorded and recreated, it could be used to unlock the car and start it.
Relay Attack
Picture your car parked securely in the driveway, with the key fob sitting safely inside your home. You're confident that your vehicle is secure, but unseen by you sophisticated thieves are planning an heist. These thieves use technology to snoop on vehicles through digital chinks. Known as relay theft, it's becoming a popular method of stealing cars with keyless entry.
The keyless entry system that is found in cars is controlled by a signal from the car's RF transmitter to the key fob. To ensure that keyless entry is not accessed by intruders the RF transmitters on the key fob as well as the car are programmed only to be activated when they are within a specific distance of each other. However, thieves can 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 person, who is at the home of the owner, uses a second gadget to transmit the signal from the key fob back to the car. This trickery fools the car into believing that the key fob is at an adequate distance to allow it to be opened and started the vehicle.
In the past, this kind of attack required expensive equipment in order to execute. Now, you can purchase relay transmitters on the inexpensive online market and carry out an heist in a matter of minutes. This is the reason why car thieves love it.
All modern cars with keyless access are at risk. Some cars are more susceptible to this kind of attack than others. In fact researchers have examined 237 popular cars and found that they can be targeted by this method.
Tesla vehicles are believed to be less susceptible to this type of theft, however the company hasn't yet implemented UWB features that would effectively conduct distance checks on the car's signal and prevent relay attacks. The company has said that they'll implement this in the near future, however until then, they are vulnerable. Installing an anti-theft device that protects both your car and your keys against such a threat is a proactive way to ensure the security of your car.
CAN Injection Attack
Modern cars can protect themselves against thieves by exchanging encrypted messages with the key in order to verify its authenticity. This system is generally reckoned to be secure, however criminals have found a way to circumvent it. They pretend to be a smart key, send messages to the vehicle, and then drive away. To do this, they get access to the smart key's internal communication network.
Today, most cars are equipped with between 20 and 200 electronic control units, or ECUs, that manage various aspects of the vehicle's operation. They communicate using a network called CAN bus. These ECUs enter a low power sleep mode to decrease their power consumption. This mode is activated when ECUs receive a "wake up" frame. These frames are usually sent by the ECU that controls the smart key or door. However they aren't always authenticated or encrypted and, therefore, could be snatched by criminals using a cheap and basic device.
They search for a location where they can connect directly to the wires for CAN connection. They usually are hidden in the headlights, or in other places in the front of the vehicle. To get them, you must remove the bumper and cut holes in the headlamp assemblies. The criminals then use a device called a CAN injection attacker to send fake messages which can trick the car's security systems into unlocking the car and disengaging its engine immobilizer.
These devices can be bought on the Dark Web and work with most major car manufacturers which include BMW and Cadillac, Chrysler, Fiat and Ford, Honda, Hyundai and Jeep, Lexus and Nissan, Renault and Toyota, Volkswagen and Maserati. The researchers who discovered this CAN Injection attack are recommending that all car makers address it in their existing models, but the reality is that these thieves will continue to steal anything they can get their hands on. We can website stop this from happening by installing mechanical safety measures, such as Discloks inside all of our cars and parking them in well-lit, well-lit areas.
Jamming the Signal
In a variation of the relay attack, which employs a device that can be used to block the signal from the key fob when the vehicle is locked. The device may be inside the pocket of a burglar in a parking area or in a hiding spot near the driveway that is being targeted. When owners press the button to lock their fobs and leave they don't consider whether or not their car is really locked. The device used by the criminal interferes with the signal to lock the car. Therefore, thieves could drive away with the vehicle.
The crooks also use devices to enhance the signal of the key fob to unlock vehicles. The crooks are able to do this even if the key is in a driver's pocket or hanging on a hook inside the home. After the car has been unlocked, they can use a standard diagnostic port or computer hacker to program a blank key fob and gain control over the vehicle.
To protect against this type of attack, car makers have come up with a range of anti-theft gadgets. However, thieves are always 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 thieves can then copy the key fob's unlock code and then start the car with this fake signal.
This method is especially popular in the US, where many cars come with wireless technology. Owners can unlock and start their vehicle through a mobile application on their smartphone. This technique is likely to increase in popularity as more companies attempt to connect their vehicles with their owners' smartphones.
It is crucial that drivers follow the right procedures to park their cars. It is not a good idea to leave keys in the ignition, and should always ensure that the car is securely locked when they're not using it and should make use of the steering wheel or a gearstick lock if possible. They should also consider installing a tracking device to their car in case it's stolen.
Flat Battery
This type of attack is more common than people think. The thieves use cheap devices that extend the signal of your key fob in order to unlock and start your car when it's off. Then they drive the car to an unmarked trailer or around a corner to take the car away. It is possible to protect your vehicle from this by installing an interrupter for the starter circuit. The simplest ones are an ON/OFF switch which interrupts the starter circuit. It's about $15 and is easy enough to install yourself.
Car thieves are constantly looking for new ways to take vehicles. The police as well as car manufacturers and insurance companies are always trying to keep up with their strategies and offer better anti-theft solutions for the latest cars. But this isn't stopping thieves who be quick to adapt and find ways to bypass the latest anti theft measures.
For instance, a lot of criminals use devices that operate on the same radio frequency as the fob to block the signal. They put the device in their pockets or close to their vehicle, and it stops the fob's lock signal from reaching the vehicle and thereby leaving the vehicle unlocked. This can be done in seconds. The device is inexpensive and can be purchased on the internet.
Another strategy is to hack the car's computer system. This is more difficult, but possible. Hackers have developed devices that connect to the diagnostic port of all vehicles and allow them to connect to the software. They can then program an unfinished fob to work. It is possible to do this on older cars also however it is more difficult without removing the ignition.
This method could be more popular if more vehicles are connected to drivers' mobile phones. Once a burglar has the username and password to an application for vehicles they can open or start the vehicle by using the app. Fortunately, you can protect yourself from these types of attacks by not putting valuables in your car and putting it in a garage or secured parking lot.
