Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or at their doors, they could unknowingly allow thieves to hijack their signal. This relay attack is just one of the high-tech methods criminals are employing to steal new keys from cars.
All 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 also to start it.
Relay Attack
Imagine your car being parked safely in the driveway, and the key fob tucked away inside 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, they are leveraging technology to hack into vehicles using digital cracks in their armor. This method of stealing cars with keys is known as relay theft.
Cars with keyless entry are designed to function using signals that are that is transmitted from 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 that are on the key fob and the car are programmed to turn on when they are within a specified distance from each other. However, thieves is able to circumvent this restriction employing a technique called the "relay-attack".
Two people are required to do this: one person is near the car and uses a device that captures a digitalized version of the signal coming 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 tricks the car into believing that the key fob is at an adequate distance to unlock and start the vehicle.
This kind of heist was once a costly process that required expensive equipment. However, now you can buy a relay transmitter on the cheap online and execute an heist in a matter of minutes. This is the reason why car thieves love it.
While certain cars are less vulnerable to this type of theft than others, all cars with keyless entry are at risk. Researchers have tested 237 of the most popular cars and found that all of them are susceptible to being stolen through this method.
Tesla vehicles are supposedly less prone to this kind of theft, but the company has not yet implemented UWB features to effectively perform distance checks on the car's signal and prevent relay attacks. The company has said that they will implement this in the future but until then, they are vulnerable. That is why it's important to adopt a proactive approach to your car security and install an anti-theft device that safeguards your keys and car from these types of attacks.
CAN Injection Attack
Modern cars can guard themselves against thieves by exchanging encrypted messages with the key in order to confirm its authenticity. The system is generally believed to be secure, however criminals have found a way around it. They simply impersonate the smart key and send messages to the car letting it unlock the doors, turn off its engine immobilizer, and let them drive away. To do this, they gain access to the smart keys' internal communications network.
Today, most cars are equipped with between 20 and 200 electronic control units (or ECUs) that manage different aspects of the car's operation. They communicate with each other using the CAN bus. These ECUs are put into a low power sleep mode to lower their power consumption. This mode is activated when ECUs receive a "wake up" frame. These frames typically come via the door or smart key receiver ECU. However they aren't always authenticated or encrypted so they could be snatched by criminals with a cheap and basic device.
To accomplish this, they must look for a place where they can directly connect to the CAN bus wires. They are usually hidden inside the headlights or elsewhere in front of the car, and are accessible by removing the bumper and cutting holes in the headlamp assembly to expose the wires. The thieves use a device known as an CAN injection attack to send out fake messages that trick the car's safety systems to unlock and disable the engine immobilizer.
These devices are available for purchase on the Dark Web, and work for the majority of major car makers, including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and many more. Researchers who have discovered the CAN Injection attack recommend that all car makers address this issue in their existing models. However, these criminals will continue to steal everything they can. We can prevent this by implementing mechanical safety measures like Discloks in all our vehicles and parking them in well-lit and visible areas.
The Signal is blocked
In a different variation of the relay attack, thieves may employ a device to block the signal from the key fob when the vehicle is locked. The device could be hidden in the pocket or in the hiding place of a thief on an open parking lot or in 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 is actually locks. The device used by the crook block the signal that locks the car. Thus, thieves are able to leave the vehicle.
They also make use of 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 on an outside hook in the home. When the car is unlocked, they can make use of an ordinary diagnostic port or computer hackers to program the 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 devices. However, criminals are constantly looking for ways to defeat these measures.
They've started 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 then start the car using this fake signal.
This technique is particularly popular in the US where a lot of cars have wireless technology. Owners can unlock and start their vehicle through a mobile application on their smartphone. This technology is likely to gain popularity as more and more companies try to connect their vehicles to owners' smartphones.
It is important that drivers follow the right procedures when parking their vehicles. It is not advisable to leave their keys in the ignition and should always secure the car when they are not in it. If they can, they should also use the gearstick or steering locking device. It is also recommended to consider installing a tracking device to their vehicle in the event that it gets 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 a car even when it's switched 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 most basic ones have an ON/OFF switch that interrupts the starter circuit. It is priced at around $15 and is simple to install.
Car thieves are always seeking new ways to rob vehicles. The police as well as car manufacturers and insurance companies are constantly trying to keep up to their tactics and provide better anti-theft systems for the latest cars. But this isn't stopping thieves who be quick to adapt and find ways to circumvent the most recent anti-theft measures.
For instance, a lot of thieves use a device that works on the same frequency as the fob to jam the signal. The device is put in the pocket or near the vehicle and blocks the fob from transmitting the lock command to the car. This can be done in just a few seconds. The device is cheap and can be purchased online.
Another strategy is to hack the car's computer system. This is more difficult but still possible. Hackers have developed devices that plug into the diagnostic port of all vehicles and allow them to connect to the software. They can then program a blank fob to work. It is also possible to do this on older cars, although it is more difficult to do without removing the ignition lock.
This method is likely to be more popular if more vehicles are connected with drivers' phones. Once a burglar has gained the username and password to a vehicle app and then they can check here unlock or start the car with the app on their phone. You can protect yourself by not leaving valuables in your car and parking in a garage.
