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 just one of the latest techniques criminals are employing to steal new keys from cars.
All keyless ignition vehicles emit a low-power radio signal to find a matching fob. If the signal is recorded and recreated, it could be used to unlock the car and to start it.
Relay Attack
Imagine your car parked in your driveway with your key fob in your home. You're sure that your car is safe, but not seen by you, sophisticated thieves are plotting an heist. They use technology to hack into vehicles using digital chinks. This method of stealing cars with keys is known as relay theft.
The keyless entry system that is found in cars is controlled by a signal by the car's radio transmitter to the key fob. To stop unauthorized keyless entry, the RF transmitters in the key fob and in the car are programmed to only activate when they're within certain distance of each other. However, thieves are able to overcome this limitation using a technique called the 'relay attack'.
To do so, two people work together: one stands by the car with the device that captures digitally the key fob's signal. The other, standing by the home of the owner and using a second device to transmit the key fob signal back to the car. This trickery fools the car into believing that the key fob has reached a distance sufficient to allow the vehicle to start and unlock. vehicle.
In the past, this kind of heist required expensive equipment to perform. Today, you can purchase a relay transmitter for a small price online and pull off a heist within minutes. This is the reason why car thieves are enthralled by it.
While certain cars are less prone to this kind of theft than others, all cars with keyless entry are vulnerable. In fact researchers have tested 237 popular cars and found that they can all be stolen using this method.
Tesla vehicles are believed to be less vulnerable to this kind of theft. However Tesla hasn't implemented UWB technology that would allow it to perform distance checks and prevent attacks via relay. The company has said it will make this happen in the near future, but for now they are still vulnerable. Installing an anti-theft system that protects both your keys and your car against these types of attacks is a proactive method to ensure the security of your car.
CAN Injection Attack
Modern vehicles are designed to shield themselves from thieves by exchanging cryptographic data with the key to prove it's genuine. The system is thought to be secure, but thieves have found ways around it. They fake the identity of a smart key, transmit messages to the vehicle and then drive away. To accomplish this, they have access to the smart keys' internal communication network.
Most cars today are equipped with between 20 and over 200 electronic control units, or ECUs, that manage various aspects of the vehicle's operation. They communicate using a network called CAN bus. To ensure that power consumption is low the ECUs are put into a low-power sleep mode that's activated when they receive a 'wake up' frame. These frames typically come through the door or a smart key receiver ECU. However, these messages aren't always encrypted or authenticated so they can be intercepted by criminals using a cheap and simple device.
They search for a location that allows them to connect directly to the CAN connection wires. They're usually hidden inside the headlights or elsewhere in the front of the car and can be accessed by pulling the bumper off and cutting holes in the headlamp assembly to expose the wires. The thieves then use a device called an CAN injection attacker, which is used to send out fake messages that fool the security systems of the car into unlocking the car and disengaging the engine immobilizer.
These devices can be bought on the Dark Web and work with all major car makers including 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 fix the issue in their current models, but the fact is that the thieves will continue to steal anything they can get their hands on. We can prevent this by implementing mechanical safety measures such as Discloks in all of our cars and parking them in well-lit, visible areas.
Jamming the Signal
In a variation of the relay attack here that uses a gadget that can be used to block the signal sent by a key fob while the car is locked. The device could be found in the pocket of a thief in a parking area or in a hideout near the driveway being targeted. Once owners hit the lock button on their fobs and leave they don't consider whether or not the car really is locked. Instead, thieves are able to escape with the vehicle since the signal that normally locks the car is blocked by the crook's device.
The crooks also employ devices to enhance the signal of 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. After the car has been unlocked, they can use the standard diagnostic port or computer hacker to program a blank key fob and gain control of the vehicle.
To guard against this kind of attack, car makers have come up with a range of anti-theft gadgets. But, as always, thieves come up with ways to thwart these measures.
They've started using devices that transmit at the same frequency as remote keyfobs to intercept signals. The thieves copy the unlock code from the key fob and begin the vehicle using this fake signal.
This technique is particularly popular in the US, where many cars are equipped with wireless technology. Owners can unlock and start their vehicle through a mobile application on their phone. This technique is likely to increase in popularity as more companies attempt to connect their cars to their owners smartphones.
In addition to incorporating anti-theft technology in vehicles, it's important for drivers to use the best practices when parking their vehicles. They should never leave their keys in the ignition, should always ensure that their car is securely locked when they're not in it and should make use of the steering wheel or a gearstick lock, if it is possible. They should also consider fitting a tracking device to their vehicle in case it's stolen.
Flat Battery
This kind of attack is more frequent than many people believe. Thieves use cheap devices to extend the signal from your key fob to unlock and start cars even if they're switched off. They then drive the car around the corner or even to a trailer and take off with it. It would be possible to protect your car from this by installing a starter circuit interrupt switch. The simplest ones just have an ON/OFF switch that shuts off the starter circuit. It costs around $15 and is simple to install.
Car thieves are always trying new ways to gain access to vehicles and then steal them. The police, car makers and insurance companies are constantly trying to catch up to their tactics and offer better anti-theft solutions for modern cars. However, this isn't stopping thieves who easily adapt and find ways to bypass 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 block the signal. They put the device in their pocket or near their vehicle, and it blocks the fob's lock command from reaching the vehicle and thereby leaving it unlocked. This can be done in seconds. The device is affordable and easily available on the internet.
Hacking the computer system of the car is an alternative option. This is more difficult, but possible. Hackers have created devices that connect to the diagnostic port of all vehicles and allow them to access the software. From there, they are able to program an unfinished key fob and make it work. It is possible to do this with older cars also but it's more difficult without removing the ignition.
As more vehicles are linked to smartphones of drivers the method is likely to be more popular. Once a thief has access to the username and password to a vehicle app, they can unlock or start the vehicle with the app. You can help be safe from these kinds of attacks by not putting valuables in your car and parking it in a garage or secured parking lot.
