Cars Being Stolen With Keyless Entry
If car owners throw 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 one of the latest techniques criminals are employing to steal new keyless cars.
Keyless ignition vehicles emit an extremely low-power radio signal, seeking a compatible fob that can respond. If the signal can be captured and recreated, it could be used to unlock the car and to 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 car is secure, but unseen by you, sophisticated thieves are plotting an attack. Instead of slamming windows and jiggling locks, thieves are leveraging technology to hack into cars via digital cracks in their armor. Known as relay theft, it's becoming a common way to steal cars with keyless entry.
The keyless entry system in cars is controlled by a signal sent by the car's radio transmitter to the key fob. To prevent keyless entry by intruders, the RF transmitters on the key fob and the car are programmed to turn on when they are within a specified distance of each other. However, thieves is able to circumvent this restriction using a technique known as the'relay-attack'.
To accomplish this two people work in tandem one is positioned by the car and uses an instrument that records an electronic version of the key fob's signal. The other, standing by the home of the owner, uses a second device to transmit the key fob's signal down to the car. This trick tricks the car into believing that the key fob is at an adequate distance to allow the vehicle to start and unlock. vehicle.
In the past, this type of attack required expensive equipment in order to execute. Today, you can purchase a relay transmitter for a small price online and pull off an heist in a matter of minutes. This is why it's so popular with car thieves.
While certain cars are less prone to this kind of theft than others, all modern vehicles that have keyless entry are vulnerable. Researchers have tested 237 of the most popular cars and found that every one of them could be taken by this method.
Tesla vehicles are said to be less vulnerable to this kind of theft. However Tesla hasn't implemented UWB technology that would allow it to conduct distance checks and prevent relay attacks. The company has stated that they will make this happen in the near future, but for now, they remain vulnerable. That is why it's important to adopt a proactive approach to your car security and install an anti-theft kit which protects your keys as well as your the car from such attacks.
CAN Injection Attack
Modern cars can guard themselves from theft by sending encrypted messages to the key to verify its authenticity. The system is believed to be secure, but criminals have found ways to circumvent it. They pretend to be a smart key, send messages to the vehicle, and then drive away. To do that they gain access to the smart key's internal communication network.
Most cars today are equipped with between 20 and over 200 electronic control units, also known as ECUs, which control various aspects of the vehicle's operation. They communicate using a network called CAN bus. To ensure that power consumption is low they ECUs go into the sleep mode at low power. This mode is activated when they receive a 'wake up' frame. These frames typically come through the door or a smart key receiver ECU. These messages are not always authenticated or encrypted. This means that thieves can take them over with a simple and cheap device.
To do this, they look for a location that allows them to connect directly to the CAN bus wires. They usually are hidden in the headlights, or in other locations in the front of the vehicle. To gain access to 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 out fake messages that fool the security systems of the car to unlock it and disable the engine immobilizer.
These devices can be bought through the Dark Web and work with the majority of major car manufacturers including 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 makers address the issue in their current models. However, these criminals will continue to take whatever they can. We can prevent this by installing mechanical safety measures such as Discloks in all of our cars and parking them in well-lit, visible areas.
Blocking the Signal
In a variation of the relay attack that employs a device that is able to block the signal sent by key fobs while the car is locked. The device may be hidden in the pocket of a thief in a parking space or in a hiding spot near the driveway that is being targeted. The owners don't know whether the vehicle is locked when they press the lock button. Instead, thieves are able to drive off with the vehicle because the signal that normally locks the car has been blocked by the device of the criminal.
The crooks also use devices to amplify the signal from the key fob in order to unlock vehicles. They may even do this when the key is inside the pocket of the driver or hanging from its hook in the home. Once the car is unlocked, they can use an ordinary computer hacker to program an unlocked key fob to gain control of the vehicle.
Car manufacturers have come up with various anti-theft devices to guard against these kinds of attacks. But, thieves are constantly looking for ways to defeat these measures.
For instance, they've begun using devices that transmit on the same 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 using this fake signal.
This technique is especially popular in the US and Europe where a large number of automobiles are equipped with wireless technology that lets owners unlock and start their vehicle by using a mobile application on their smartphone. This technology is likely to increase in popularity as more companies attempt to link their cars with their owners' smartphones.
In addition to installing anti-theft technologies in vehicles, it's crucial for drivers to use the best practices when they park their vehicles. It is not a good idea to leave keys in the ignition, should always ensure that the vehicle is locked completely when they're not there and should use the steering wheel or a gearstick lock if possible. They should also think about installing a tracking device onto their vehicle in the event it is stolen.
Flat Battery
This kind of attack happens more often than we think. Thieves make use of cheap devices to extend the signal from your key fob to unlock and begin a car even when it's turned off. Then, they drive the car to a trailer or around a corner to take the car away. Installing an interrupter switch for the starter circuit would protect your car against this. Simpler versions include an ON/OFF button which interrupts the circuit. It is priced at around $15 and is simple to install.
Car thieves are always trying new ways to gain access to vehicles and then steal them. Car manufacturers, police and insurance companies are constantly trying to keep up with the latest tactics and more info provide more effective anti-theft systems for modern vehicles. But this isn't stopping thieves who easily adapt and find ways to bypass the latest anti theft measures.
A lot of thieves block the signal by using devices that operate on the same radio frequency as the fob. They place the device in their pocket or somewhere close to their vehicle, and it stops the fob's lock signal from reaching the vehicle, leaving the vehicle unlocked. This can be done in just a few seconds. The device is cheap and available on the internet.
Hacking the computer system of the car is another option. This is more difficult but still feasible. Every car has an diagnostic port and hackers have created devices that plug into them and let them access the car's software. They can then program a blank fob to work. It is possible to do this on older vehicles as well but it's more difficult if you remove the ignition.
As more vehicles are linked to the phones of drivers the method is likely to be more popular. Once a burglar has access to the username and password to a vehicle application, they can unlock or start the vehicle by using the application. It is possible to defend yourself from these kinds of attacks by not leaving valuables in your car and parking it in a garage or secured parking lot.
