Cars Being Stolen With Keyless Entry
If car owners throw their keys on the table or at their doors, they could unknowingly allow thieves to steal their signal. This relay attack is a high-tech technique used by criminals to steal keyless vehicles.
Keyless ignition cars emit a low-power radio signal looking for a matching fob to respond. If the signal can be recorded and recreated, it could be used to unlock the car and start it.
Relay Attack
Imagine your car being parked safely in the driveway, with the key fob sitting safely inside your home. You're sure that your car is safe, but unnoticed by you sophisticated thieves are planning an attack. These thieves use technology to hack into vehicles via digital chinks. This is known as relay theft, it's an increasingly common method of stealing vehicles with keyless entry.
The keyless entry system that is found in cars is controlled by a signal by the car's RF transmitter to the key fob. To prevent unauthorized keyless entry the RF transmitters on the key fob as well as in the car are programmed to only activate when they're within a certain distance from each other. The thief can bypass this restriction by employing a method known as the relay-attack.
To do so two people work together: one stands by the car, using an instrument that records a digitized version of the key fob's signal. The other person, who is at home with the owner and uses a different device to transmit the signal from the key fob back to the car. This trickery fools the car into thinking that the key fob is near enough to be able to unlock it and start the engine.
This type of attack was once a costly process that required expensive equipment. Today, you can purchase a cheap relay transmitter online and carry out an heist in a matter of minutes. This is the reason it's popular among car thieves.
While some cars are less susceptible to this type of theft than others, all modern vehicles that have keyless entry are at risk. In fact, researchers have tested 237 vehicles that are popular and found that they can be targeted by this method.
Tesla vehicles are believed to be less vulnerable to this kind of theft. However, the company hasn't yet implemented UWB technology to allow it to perform distance checks and stop attacks via relay. The company has said it will make this happen in the near future, but until then, they remain vulnerable. Installing an anti-theft device that guards your car and your keys against such a threat is a proactive way to ensure the security of your vehicle.
CAN Injection Attack
Modern cars are designed to protect themselves from theft by exchanging cryptographic data with the key to prove that it's authentic. The system is thought to be safe, but criminals have found ways to circumvent it. They fake the identity of a smart key, transmit messages to the vehicle and then drive away. To do this, they get access to the smart key's internal communication network.
The majority of cars today are fitted with between 20 and 200 electronic control units, or ECUs, which control various aspects of the vehicle's operation. They communicate with each other via the CAN bus. These ECUs enter a low-power sleep mode to reduce their power consumption. This mode is activated when ECUs receive an "wake up" frame. These frames are usually sent by the ECU that controls the smart key or door. These messages aren't always encrypted or authenticated. This means that criminals are able to intercept them with an inexpensive and simple device.
To accomplish this, they search for a spot where they can directly connect to the CAN bus connector wires. They usually hide in the headlights or in other places in the front of the vehicle. To gain access to them, you can remove the bumper and cut holes in the headlamp assemblies. The criminals then employ a device known as an CAN injection attacker, which is used to send fake messages which trick the car's security systems into unlocking it and disengaging the engine immobilizer.
These devices can be bought through 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. Researchers who have discovered the CAN Injection attack recommend that all car manufacturers fix the issue in their current models. However, the thieves will continue to take everything they can. The best we can do is to attempt to stop this from happening by installing security measures that are mechanical like Discloks on our vehicles, and making sure that they are located in areas with adequate lighting that are clearly visible to passers-by.
The Signal is blocked
In a variation of the relay attack that uses a gadget that can be used to block the signal sent by a key fob while the vehicle is locked. The device may be in the pocket of a burglar in a parking area or in a hidden spot close to the driveway that is being targeted. Once owners hit the button to lock their fobs and walk away they don't consider whether or not the car really is locked. The device used by the criminal block the signal that locks the car. Therefore, thieves could drive away with the vehicle.
They also make use of devices that amplify signals from the key fob to unlock vehicles. They may even accomplish this if the key is in the driver's pocket or hanging from its hook in the house. After the car has been unlocked, they can make use of the standard diagnostic port or computer hacker to program a blank key fob and gain control over the vehicle.
To safeguard against this kind of attack, car makers have developed a variety of anti-theft devices. However, thieves will always come up with ways to thwart these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs to intercept signals. The thieves copy the unlock code of the key fob and begin the vehicle using this fake signal.
This technique is especially popular in the US and Europe where a large number of vehicles are equipped with wireless technology that lets owners unlock and start their vehicle with a mobile app on their smartphone. This technology is likely to become more popular as more manufacturers try to link their cars with their owners phones.
It is important that drivers use best practices to park their vehicles. They should never leave their keys in the ignition and always secure the car when not in it. If possible, they should also use a steering or gearstick locking device. They should also think about installing a tracking device to their car in case it gets stolen.
Flat Battery
This kind of attack is more prevalent than people think. Thieves use cheap devices to extend the signal from your key fob to unlock and begin the car, even if it's turned off. They then drive the car around a corner or even to a trailer and take off with it. It would be possible to shield your vehicle from this by installing a starter circuit interrupt switch. The simplest ones are an ON/OFF switch which interrupts the starter circuit. It costs about $15 and is easy enough to install by yourself.
Car thieves are always looking for new ways to gain access to vehicles and then steal them. Police, car manufacturers and insurance companies are get more info always trying to stay abreast of the latest methods and offer more effective anti-theft systems for modern vehicles. But this does not stop thieves who are able to adapt quickly and find ways to bypass the latest anti theft measures.
For instance, a lot of thieves use devices that operate on the same frequency as the fob in order to block the signal. The device is put in the pocket or near the vehicle and prevents the fob from sending the signal to the car. This can be done within minutes. The device is cheap and readily available online.
Another option is to hack the car's computer system. This is harder but still feasible. All cars have an diagnostic port and hackers have developed devices that connect to them and let them access the car's software. From there, they can program an unfinished key fob and start working. It is possible to do this with older cars too, but it's more difficult if you remove the ignition.
This technique could become more popular if more vehicles are connected with drivers' phones. Once a burglar has gained the username and password for the vehicle app, they can then open the car or get it started with the app on their phone. You can guard yourself by not leaving valuables inside your car, and also by parking in a garage.
