Cars Being Stolen With Keyless Entry
If car owners throw their keys on the table or next to their doors, they could not realize that they are allowing thieves to steal their signal. This relay attack is a highly-tech method used by criminals to steal new keyless vehicles.
Keyless ignition vehicles emit a low-power radio signal seeking a compatible fob to respond. 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, with the key fob sitting safely in your home. You're confident that your vehicle is safe, but unnoticed by you, sophisticated thieves are plotting a heist. They use technology to snoop on vehicles through digital chinks. This method of stealing vehicles 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 ensure that keyless entry is not accessed by unauthorized individuals, the RF transmitters on the key fob as well as the car are programmed to activate when they are within a specified distance from each other. A thief, however, can circumvent this limitation employing a technique called the relay-attack.
Two individuals are required to perform this: one person stands near the car and utilizes a device to capture a digitalized version of the signal coming from the key fob. The other who is at the owner's home, uses a second gadget to transmit the signal from the key fob to the car. This trick tricks the car into thinking the key fob is close enough to be able to unlock it and start the engine.
In the past, this kind of attack required expensive equipment to carry out. But now, you can pick up relay transmitters on the inexpensive online market and carry out an heist in a matter of minutes. This is the reason it's popular with car thieves.
All modern cars with keyless access are vulnerable. Certain cars are more susceptible to this type than others. In fact, researchers have tested 237 vehicles that are popular and found that they could be targeted by this method.
Tesla vehicles are believed to be less prone to this kind of theft. However, the company hasn't yet implemented UWB technology that would allow it to conduct distance checks and prevent attacks via relay. The company has said that they will do this in the future but until then, they're vulnerable. Installing an anti-theft device that protects both your car keys and your keys against such a threat is a proactive method to ensure the security of your car.
CAN Injection Attack
Modern cars are designed to shield themselves from theft by transferring cryptographic messages using the key to prove that it's genuine. The system is thought to be secure, however criminals have found ways to circumvent it. They impersonate the smart key, then send messages to the vehicle and then drive away. To do this they have 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, that control different aspects of the vehicle's operation. They communicate with one another using an electronic network referred to as CAN bus. To reduce power consumption the ECUs enter sleep mode with low power that is activated when they receive a 'wake up' frame. These frames typically come from the door or smart key receiver ECU. These messages aren't always encrypted or authenticated. This means that thieves can take them over with a simple and cheap device.
To accomplish this, they must look for a place where they can directly connect to the CAN bus wires. They usually are hidden in the headlights or in other areas of the front of the vehicle. To get them, you need to remove the bumper and cut holes in the headlamp assemblies. The thieves use the device referred to as an CAN injection attack to send fake messages which fool the safety systems of the car to unlock and disable the engine immobilizer.
These devices can be purchased 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. The researchers who discovered this CAN Injection attack are recommending that all car manufacturers fix the issue in their current models, but the fact is that these thieves will continue to take everything they can lay their hands on. We can stop this from happening by installing mechanical safety measures like Discloks in all of our cars and parking them in well-lit, visible areas.
The Signal is blocked
In a different variation of the relay attack, thieves could make use of a device to block the signal that is sent by a key fob when the car is locked. The device may be hidden in the pocket of a thief in a parking area or in a hidden spot near the driveway that is being targeted. Once the owners press the lock button on their fobs, and then walk away and leave, they don't have to think about whether or not their car is really locked. Instead, thieves can escape with the vehicle because the signal that normally locks the car has been blocked by the device of the criminal.
They also make use of devices that amplify signals from the key fob to unlock vehicles. They can even do this when the key is in the pocket of the driver or hanging from a hook inside the house. After the car has been unlocked, they can use a standard computer hacker to program a blank key fob and gain control over the vehicle.
Automobile manufacturers have developed a variety of anti-theft solutions to protect against these types of attacks. But, as always, thieves find ways to defeat these measures.
For instance, they've been using devices that transmit on the same frequency as remote key fobs in order to intercept their signals. The thieves then copy the unlock code of the key fob and start the vehicle using this fake signal.
This technique is especially popular in the US and Europe where a lot of vehicles are equipped with wireless technology that allows owners to unlock and start their vehicle using a mobile app on their phone. This technology is likely to become more popular as more manufacturers try to link their cars with their owners' smartphones.
It is essential that drivers use best practices when parking their vehicles. They should never leave their keys in the ignition, should always ensure that the car is securely locked when they're not in it and should make use of a steering wheel or gearstick lock, if they can. They should also consider having a tracking device fitted to their car in case it is stolen.
Flat Battery
This kind of attack is more frequent than most people realize. Thieves make use of inexpensive devices to extend the signal from your key fob to unlock and start the car, even if it's shut off. They then drive the car around a corner or even to a trailer and then drive off with it. Installing a starter circuit interruption switch would protect your car against this. The simplest ones are an ON/OFF switch which interrupts the starter circuit. It is priced at around $15 and is easy to install.
Car thieves are always trying new ways to enter vehicles and then steal them. Car manufacturers, police and insurance companies are always trying to keep up with the latest methods and offer better anti-theft systems for modern vehicles. But that doesn't stop the thieves who are able to be quick to adapt and discover ways to bypass the most up-to-date anti-theft systems.
For instance, many thieves use a device that works on the same radio frequency as the fob to block the signal. The device is placed in the pocket or close to the vehicle and blocks the fob from sending click here the lock command to the car. This can be done in a matter of seconds. The device is cheap and readily available online.
Hacking the computer system of the car is an alternative option. This is more difficult but feasible. Hackers have designed devices that connect to the diagnostic port of all vehicles and allow them to connect to the software. From there, they can program a blank key fob and get it to work. It is possible to do this with older cars as well but it's more difficult without removing the ignition.
As more vehicles are linked to the phones of drivers and this method could become more popular too. Once a thief has access to the username and password to an application for vehicles and is able to unlock or start the vehicle with the app. You can guard yourself by not leaving valuables in your car and by parking in a garage.
