Cars Being Stolen With Keyless Entry

If car owners leave their keys on the table or near their door, they may unknowingly allow thieves to steal their signal. This relay attack is one of the latest techniques criminals are using to steal brand new keyless vehicles.

All keyless ignition vehicles emit a low-power radio signal to locate the fob that matches. If the signal is captured and recreated it can be used to unlock the car and start it up.

Relay Attack

Imagine your car safely in your driveway, and your key fob at home. You're sure that your car is safe, but not seen by you, sophisticated thieves are plotting an attack. Instead of breaking windows or jimmying locks, thieves are leveraging technology to gain access to cars through digital cracks in their armor. 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 sent from the car's RF transmitter to the key fob. To stop keyless entry by intruders the RF transmitters that are 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 bypass this restriction by employing a technique called the "relay-attack".

To accomplish this two people work in tandem: one stands by the car and uses a device that captures an electronic version of the key fob's signal. The other, who is at the owner's house is using a different device to transmit the key fob's signal down to the car. This trickery tricks the car into thinking that the key fob is at the distance needed to allow the vehicle to start and unlock. vehicle.

This type of attack used to require expensive equipment. But now, you can buy a relay transmitter on the cheap online and execute the heist in just a few minutes. This is why it's so popular with car thieves.

While certain cars are less prone to this kind of theft than others, all modern vehicles with keyless entry are vulnerable. In fact, researchers have tested 237 vehicles that are popular and found that they could be targeted by this method.

Tesla cars are said to be less susceptible to this type of theft, but the company hasn't yet implemented UWB features to effectively perform distance checks on the car's signal to protect against relay attacks. The company has stated that they will do this in the near future, however until then, they're vulnerable. Installing an anti-theft device that safeguards your keys and your car against these types of attacks is a proactive approach to ensure your car's security.

CAN Injection Attack

Modern vehicles can defend themselves from thieves by transferring encrypted messages using the key to verify its authenticity. This method is generally thought to be secure, however criminals have found a way to circumvent it. They can pretend to be the smart key and send messages to the car, letting it unlock the doors, turn off its engine immobilizer, and let them drive away. To do that they have access to the smart key's internal communications network.

These days, most cars are fitted with between 20 and 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate via the CAN bus network. These ECUs enter a low power sleep mode to decrease their power consumption. This mode is activated when the ECUs receive an "wake up" frame. These frames are typically sent by the ECU that controls the smart key or door. However the messages aren't usually encrypted or authenticated and, therefore, could be snatched by criminals who have a low-cost and simple device.

To do this, they look for a location that allows them to connect directly to the CAN bus connector wires. They usually hide in the headlights or in other places in the front of the vehicle. To access them, you can 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 that can trick the security systems of the car to unlock and disable the engine immobilizer.

These devices are available for sale on the Dark Web, and work for all major car manufacturers, including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and more. Researchers who have discovered the CAN Injection attack recommend that all car manufacturers fix this in their existing models. However, these thieves will continue to steal whatever they can. The best thing we can do is attempt to stop this from happening by installing mechanical security measures such as Discloks on all of our vehicles, and making sure that they are always located in areas with adequate lighting that are clearly visible to passers-by.

The Signal is blocked

In a different variation of the relay attack, thieves could use a gadget to jam the signal sent from the key fob when the car is locked. The device could be in the pocket or in the hiding the location of a thief in the parking lot, or even near the driveway being targeted. Owners aren't able to verify whether their vehicle is locked here when they press the lock button. Instead, thieves can take off with the car because 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 key fob's signals in order to unlock vehicles. The crooks are able to do this even when the key is inside a pocket of a driver, or hanging on a hook inside the home. After the car is unlocked, hackers can use a standard diagnosis port to program an unlocked fob.

Car manufacturers have developed various anti-theft devices to protect against these types of attacks. However, thieves will always come up with ways to thwart these measures.

They've been using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The crooks then copy the unlock code of the key fob and start the vehicle with this fake signal.

This technique is particularly popular in the US in which many vehicles have wireless technology. Owners can start and unlock their car using a mobile application on their phone. This technology is expected to become more popular as more and more companies try to connect their vehicles with their owner's smartphones.

It is essential that drivers follow the right procedures to park their cars. They should never leave their keys in the ignition and always lock the car when they are not in it. If possible they should also utilize the gearstick or steering locking device. They should also think about installing a tracking device to their car in case it's stolen.

Flat Battery

This kind of attack is more common than most people realize. Thieves make use of cheap devices to extend the signal from your key fob to unlock and begin a car even when it's shut off. Then, they drive the car to an unmarked trailer or around a corner and 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 which interrupts the circuit. It costs around $15 and is simple to install.

Car thieves are always trying new ways to get into vehicles and steal them. Car manufacturers, police and insurance companies are always trying to keep up with the latest methods and offer more effective anti-theft systems for modern vehicles. But this isn't stopping thieves who easily adapt and find ways to circumvent the latest anti-theft technology.

For instance, many thieves use devices that operate on the same radio frequency as the fob to block the signal. They put the device in their pockets or somewhere near their vehicle, and it blocks the fob's lock signal from reaching the vehicle and thereby leaving it unlocked. This can be accomplished in a matter of seconds. The device is affordable and available online.

Hacking the computer system of the car is an alternative option. This is harder but still possible. All cars have an diagnostic port, and hackers have developed devices that plug into them and let them access the software of the car. From there, they can program the blank key fob to make it work. It is possible to do this with older cars also, but it's more difficult if you remove the ignition.

As more vehicles are linked to smartphones of drivers the method is likely to become more popular as well. Once a criminal has the username and password to a vehicle app, they can unlock or start the vehicle using the app. It is possible to be safe from these kinds of attacks by not leaving valuables in your car, and then parking it in a secure garage or parking lot.
