Cars Being Stolen With Keyless Entry
If car owners throw their keys on the table or next to their door, they may unknowingly allow thieves to hijack their signal. This relay attack is a highly-tech method criminals use to steal keyless vehicles.
Keyless ignition cars emit a low-power radio signal looking for a matching fob that can respond. If the signal can be recorded and recreated, it can be used unlock the car and start it.
Relay Attack
Imagine your car being parked safely in the driveway, with the key fob safely in your home. You're confident that your car is safe, but unnoticed by you sophisticated thieves are planning a heist. They use technology to snoop on vehicles through digital chinks. This method of stealing cars that have keyless access 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 prevent keyless entry by intruders the RF transmitters that are on the key fob and the car are programmed only to turn on when they are within a specific distance from each other. However, a thief can override this restriction using a technique known as the'relay attack'.
To do so two people work together One stands near the car with the device that captures a digitized version of the key fob's signal. The other, who is at the owner's home is using a second device 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 unlock and start the engine.
In the past, this type of heist required expensive equipment to carry out. It is now possible to purchase an inexpensive relay transmitter online and pull off an heist in a matter of minutes. This is the reason why car thieves are enthralled by it.
While some cars are less prone to this kind of theft than others, all modern cars that have keyless entry are at risk. In fact, researchers have tested 237 popular cars and found that they can all be stolen using this method.
Tesla vehicles are said to be less susceptible to this kind of theft. However Tesla hasn't yet implemented UWB technologies that would allow it to perform distance checks and prevent relay attacks. The company has stated that they will implement this in the near future, but until then they are vulnerable. That is why it's important to adopt a proactive approach to your vehicle security and install an anti-theft device that safeguards your keys and the car from such attacks.
CAN Injection Attack
Modern vehicles can defend themselves from theft by exchanging encrypted messages with the key in order to verify its authenticity. This method is generally thought to be secure, however thieves have found a way to circumvent it. They impersonate a smart key, transmit messages to the vehicle and then drive off. 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 using a network called CAN bus. To keep power consumption low the ECUs go into sleep mode with low power that is activated when they receive a wake up frame. These frames are typically sent through the door or a smart key receiver ECU. These messages aren't always encrypted or authenticated. This means that thieves can intercept them with a simple and cheap device.
To accomplish this, they search for a spot where they can connect directly to the CAN bus wires. They usually are hidden in the headlights, or in other locations in the front of read more the vehicle. To gain access to them, you can remove the bumper and make holes in the headlamp assemblies. The criminals then employ a device known as an CAN injection attacker, which is used to send fake messages that fool the security systems of the car into unlocking it and disengaging the engine immobilizer.
These devices are for sale on the Dark Web, and work for all 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 in their existing models. However, the thieves will continue to steal whatever they can. The best thing we can do is to try and prevent this by installing security measures that are mechanical like Discloks on our cars and ensuring that they are parked in well-lit areas that are clearly visible to people passing by.
Blocking the Signal
In a variation of the relay attack that employs a device, thieves can jam the signal sent by a key fob while the car is locked. The device could be inside the pocket of a thief in a parking space or in a hiding spot near the driveway that is being targeted. Owners don't check whether their vehicle is locked when they press the lock button. Instead, thieves can take off with the car since the signal that normally locks the car has been blocked by the crook's device.
The crooks also make use of devices to amplify the signal from the key fob in order to unlock vehicles. The crooks can do this even when the key is inside a pocket of a driver, or hanging from a hook inside the home. When the car is unlocked, they can use a standard diagnostic port or computer hacker to program a blank key fob and gain control over the vehicle.
Car manufacturers have developed a range of anti-theft systems to safeguard against these types of attacks. But, as always, thieves come up with new ways to beat these measures.
For instance, they've been using devices that transmit on the same frequency as remote key fobs to intercept their signals. The thieves copy the unlock code of the key fob, and then start the vehicle using this fake signal.
This technique is particularly popular in the US in which many vehicles have wireless technology. Owners can unlock and start their vehicle through a mobile application from their mobile. This technology will likely increase in popularity as more companies attempt to link their cars with their owners' smartphones.
In addition to incorporating anti-theft technology in vehicles, it's vital for drivers to leverage best practices when they park their vehicles. They shouldn't leave their keys in the ignition, and should always make sure the car is securely locked when they're not there and should utilize the steering wheel or a gearstick lock, if it is possible. It is also recommended to consider having a tracking device fitted to their car in case it's stolen.
Flat Battery
This type of attack is more prevalent than most people realize. The thieves use cheap devices that extend the signal of your key fob to unlock and start your car, even if it is off. Then they drive the car to a trailer or around a corner to take it away. Installing an interrupter switch for the starter circuit will protect your vehicle from this. Simpler versions come with an ON/OFF button that shuts off the circuit. It costs around $15 and is easy to install.
Car thieves are always working on new ways to get into vehicles and then steal them. Police, car manufacturers and insurance companies are always trying to keep up with the latest techniques and offer better anti-theft systems for modern vehicles. However, that doesn't stop thieves who are able to change quickly and discover ways to bypass the most up-to-date anti-theft systems.
For example, many thieves use a device that works on the same frequency as the fob to block the signal. The device is tucked away in the pocket or close by the vehicle and blocks the fob from sending the lock command to the car. This can be done within seconds. The device is affordable and available online.
Hacking the computer system of the car is an alternative option. This is more difficult, but possible. Hackers have designed devices that connect to the diagnostic port of all cars and allow them to connect to the software. They can then program a blank fob to function. This is also possible on older vehicles, but it is more difficult to do so without removing the ignition lock.
This technique could become more popular if more vehicles are connected to drivers' phones. Once a criminal has the username and password to the vehicle app and then they can open the car or get it started with the app on their phone. It is possible to protect yourself from these types of attacks by not leaving valuables in your car and parking it in a garage or secured parking lot.
