Cars Being Stolen With Keyless Entry
If car owners throw their keys on the table or next to their doors, they may not realize that they are allowing thieves to steal their signal. This relay attack is just one of the high-tech methods criminals are using to steal brand new keyless cars.
Keyless ignition vehicles emit a low-power radio signal that is used to locate the fob that matches. If the signal can be captured and recreated, it can be used to unlock the car and start it.
Relay Attack
Picture your car parked securely in the driveway, and the key fob safely inside your home. You're confident that your vehicle is safe, but unnoticed by you sophisticated thieves are planning an heist. These thieves use technology to snoop on vehicles through digital chinks. This method of stealing cars that have keyless access is called relay theft.
Cars with keyless entry are designed to operate via a signal sent from the remote control (RF) transmitter to the owner's key fob. To ensure that keyless entry is not accessed by unauthorised persons the RF transmitters that are on the key fob as well as the car are programmed to turn on when they are within a specified distance from each other. The thief is able to circumvent this restriction employing a method known as the relay-attack.
To do so, two people work together One stands near the car, using a device that captures a digitized version of the key fob's signal. The other, who is at the owner's house, uses a second device to transmit the key fob's signal to the car. This trickery tricks the car into thinking that the key fob has traveled an adequate distance to allow it to be opened and started the vehicle.
This type of heist used to require expensive equipment. It is now possible to purchase a cheap relay transmitter online and carry out an heist in a matter of minutes. This is why it's so well-liked by car thieves.
While some cars are less susceptible to this kind of theft than others, all modern vehicles with keyless entry are at risk. Researchers have tested 237 of the most popular cars and found that all of them are susceptible to being stolen through this method.
Tesla vehicles are said to be less vulnerable to this kind of theft. However, the company hasn't yet implemented UWB technologies that would allow it to conduct distance checks and prevent relay attacks. The company has stated that they will do this in the near future, but until then, they're vulnerable. Installing an anti-theft system that guards your keys and your car against such attacks is a proactive method to ensure the security of your car.
CAN Injection Attack
Modern cars are designed to shield themselves from thieves by transferring cryptographic messages using the key to prove it's authentic. The system is believed to be secure, however thieves have found ways to get around it. They can impersonate the smart key and send other messages to the car, letting it unlock the doors, turn off its engine immobilizer, and let them leave the car. To achieve this, they need access to the smart keys' internal communications network.
Today, most cars are equipped with between 20 to 200 electronic control units (or ECUs) that manage different aspects of the car's operation. They communicate via a network called CAN bus. These ECUs enter a low power sleep mode to reduce their power consumption. This mode is activated when the ECUs receive an "wake up" frame. These frames are usually sent via the door or smart key receiver ECU. However they aren't always encrypted or authenticated and, therefore, can be intercepted by criminals who have a low-cost and simple device.
To accomplish this, they search for a location that allows them to connect directly to the CAN bus connector wires. They are usually hidden in the headlights or in other locations in the front of the vehicle. To access them, you must remove the bumper and make holes in the headlamp assemblies. The thieves then employ a device known as an CAN injection attacker, which is used to send out fake messages that can trick the car's security systems into unlocking it and disengaging its engine immobilizer.
The devices are available 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. The researchers who discovered this CAN Injection attack are recommending that all car makers address the issue in their current models, but the reality is that the thieves will continue to take whatever they can get their hands on. The best we can do is try and prevent this by installing security measures that are mechanical such as Discloks on all of our vehicles and ensuring that they are located in areas with adequate lighting that are clearly visible to people passing by.
Blocking the Signal
In a variant different to the relay attack, thieves could make use of a device to block the signal that is sent by a key fob when the vehicle is locked. The device could be hidden in the pocket or hiding where a burglar is hiding on a parking lot, or in the driveway that is being targeted. Owners don't check whether the vehicle is locked after pressing the lock button. Instead, thieves could take off with the car since the signal that normally locks the car is blocked by the device of the criminal.
They also have devices that amplify signals from the key fob to unlock vehicles. The crooks can do this even if the key is in a driver's pocket, or hanging from an outside hook in the home. After the car has been unlocked, they can make use of an ordinary diagnostic port or computer hackers to program a blank key fob and gain control over the vehicle.
To safeguard against this kind of attack, car manufacturers have come up with a range of anti-theft devices. But, as always, thieves come up with ways to thwart these measures.
For instance, they've begun using devices that transmit on the same radio frequency as remote key fobs 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 method is especially popular in the US where a lot of cars have wireless technology. Owners can unlock and start their vehicle by using a mobile app from their mobile. This technology is likely to become increasingly popular as more and more companies attempt to connect their vehicles with their owner's smartphones.
It is important that drivers follow the best practices to park their vehicles. They should never leave their keys in the ignition and always lock the car when not in it. If they can it is also recommended to use a gearstick lock or steering device. They should also think about installing a tracking device on their vehicle in the event that it is stolen.
Flat Battery
This type of attack is more common than many people believe. The thieves employ low-cost devices that increase the signal of your key fob in order to unlock and start your car even if it is off. They then simply drive the car around a corner or onto a trailer to leave with it. It would be possible to protect your car from this by installing a starter click here circuit interrupt switch. Simpler versions include an ON/OFF button that interrupts the circuit. It costs around $15 and is simple to install.
Car thieves are constantly looking for new ways to rob vehicles. Car manufacturers, police and insurance companies are always trying to keep up with the latest techniques and offer better anti-theft systems for modern vehicles. However, this isn't stopping thieves who be quick to adapt and find ways around the latest anti-theft technology.
A lot of thieves block the signal by using a device that uses the same radio frequency as the fob. The device is placed in the pocket or close to the vehicle, and stops the fob from sending the lock command to the vehicle. This can be accomplished in just a few seconds. The device is cheap and easily accessible on the internet.
Another option is to hack into the car's computer system. This is more difficult, but still possible. Hackers have created devices that plug into the diagnostic port of all cars and allow them to connect to the software. From there, they can program an unfinished key fob and make it work. It is possible to do this on older vehicles as well however it is more difficult if you remove the ignition.
This method is likely to be more popular if more vehicles are connected to drivers' phones. Once a criminal has the username and password to a vehicle app, they can unlock or start the vehicle using the app. You can guard yourself by not putting valuables inside your car, and also by parking in a garage.
