Cars Being Stolen With Keyless Entry
Car owners who toss keys on tables or near their front doors could be permitting thieves to steal the signal. This relay attack is a high-tech technique used by criminals to steal new keyless vehicles.
Keyless ignition vehicles emit a low-power radio signal to find the fob that matches. If the signal is captured and recreated, it can be used to unlock the car and then start it up.
Relay Attack
Imagine your car safely parked in your driveway with your key fob in your home. You're confident that your car is secure, but unseen by you, sophisticated thieves are plotting an attack. The thieves employ technology to hack into vehicles using digital chinks. This method of stealing cars that have keys is known as relay theft.
Keyless entry cars are designed to operate via an electronic signal that is that is transmitted by the car's remote control (RF) transmitter to the owner's key fob. To stop keyless entry by unauthorised persons the RF transmitters that are on the key fob and the car are programmed to turn on when they are within a certain distance of each other. However, a thief can overcome this limitation using a technique called the 'relay attack'.
To accomplish this, two people work in tandem: one stands by the car with a device that captures digitally the key fob's signal. The other, in the vicinity of the owner's house, 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 the distance needed to unlock and start the vehicle.
In the past, this kind of heist required expensive equipment in order to execute. Now, you can pick up a relay transmitter on the inexpensive online market and carry out an heist in a matter of minutes. This is why car thieves love it.
While certain cars are less vulnerable to this type of theft than others, all modern cars that have keyless entry are vulnerable. Researchers have tested 237 popular automobiles and found that all of them are susceptible to being stolen using this method.
Tesla vehicles are supposedly less prone to this kind of theft, however the company hasn't yet implemented UWB features that would effectively perform distance checks on the car's signal and prevent relay attacks. The company has said it will do so in the future, but for now they are vulnerable. That's why it's essential to be proactive about your car security and install an anti-theft tool that protects your keys and car from these types of attacks.
CAN Injection Attack
Modern vehicles are designed to protect themselves from theft by exchanging cryptographic messages with the key to prove that it's authentic. This system is generally reckoned to be secure, but criminals have found a way 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 then drive away. To do this they have access to the smart key's internal communications network.
Most cars today are equipped with between 20 and 200 electronic control units, or ECUs, which control various aspects of the vehicle's operation. They communicate via an electronic network known as CAN bus. These ECUs enter a low-power sleep mode to lower their power consumption. This mode is activated when ECUs receive an "wake up" frame. These frames typically come through the door or a smart key receiver ECU. These messages are not always encrypted or authenticated. This means that criminals can take them over with a simple and cheap device.
They search for a spot where they can connect directly to the wires of the CAN connection. These are often hidden away within the headlights or in the front of the car and can be accessed by pulling the bumper off and cutting holes in the headlamp assembly to expose them. The thieves then employ a device dubbed an CAN injection attacker, which is used to send fake messages which fool the security systems of the car into unlocking the car and disengaging its engine immobilizer.
These devices can be purchased on 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 makers fix the issue in their current models, but the reality is that thieves will continue to steal whatever they can get their hands on. The best thing we can do is try and prevent this by putting in mechanical security measures like Discloks on our vehicles and ensuring that they are located in areas with adequate lighting that are easily visible to pedestrians.
Jamming the Signal
In a different variation of the relay attack, thieves may make use of a device to block the signal that is sent by the key fob when the car is locked. The device could be hidden in the pocket or in the hiding the location of a thief in a parking lot, or near the driveway being targeted. Once the owners press the button to lock their fobs and walk away they don't consider whether or not their car is really locked. The device of the crook interferes with the signal to lock the car. Thus, thieves are able to leave the vehicle.
The crooks also make use of devices to enhance the signal of the key fob to unlock vehicles. The crooks are able to do this even when the key is inside a driver's pocket or hanging from an outside hook in the home. When the car is unlocked, they can make use of an ordinary computer hacker to program an unlocked key fob to gain control of the vehicle.
To protect against this type of attack, car makers have developed a variety of anti-theft gadgets. But thieves always come up with ways to thwart these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The thieves then 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, where many cars have wireless technology. Owners can unlock and start their vehicle by using a mobile app on their smartphone. This technology will likely become more popular as more manufacturers try to connect their cars to get more info their owners' smartphones.
In addition to installing anti-theft technologies in vehicles, it's important for drivers to follow the best practices when they park their cars. It is not advisable to leave the key fobs in ignition and lock the car when not in it. If they can they should also utilize a steering or gearstick locking device. They should also consider installing a tracking device onto their vehicle in the event it's stolen.
Flat Battery
This kind of attack is more common than most people realize. The thieves make use of low-cost devices that increase the signal from your key fob to unlock and start your car even when it's off. Then, they drive the car to the trailer or around a corner and take the car away. It would be possible to shield your vehicle from this by installing a starter circuit interrupt switch. The simplest ones just have an ON/OFF switch that interrupts the starter circuit. It's about $15 and is simple to install.
Car thieves are constantly looking for new ways to rob vehicles. The police as well as car manufacturers and insurance companies are always trying to catch up with their strategies and develop better anti-theft systems for modern vehicles. However, that doesn't stop thieves who are able to be quick to adapt and find ways to circumvent the most recent anti-theft measures.
A lot of thieves block the signal using devices that operate on the same radio frequency of the fob. They put the device in their pockets or somewhere near their vehicle, and it prevents the fob's lock signal from reaching the car, leaving the vehicle unlocked. This can be accomplished in a matter of seconds. The device is affordable and can be purchased online.
Another strategy is to hack the car's computer system. This is more difficult, but it is still possible. Every car has an diagnostic port and hackers have developed devices that plug into them and let them access the software of the car. They can then program a blank fob to work. It is possible to do this on older vehicles too, but it's more difficult if you remove the ignition.
This method could become more popular if more vehicles are connected to drivers' mobile phones. Once a criminal has the username and password to an app for vehicles and then they can open the car or get it started by using the app on their phone. You can protect yourself by not putting valuables in your car and also by parking in garages.
