Cars Being Stolen With Keyless Entry

Car owners who toss their keys on tables or near their front door may be unwittingly permitting thieves to steal the signal. This relay attack is a highly-tech method criminals use to steal keys from new vehicles.

Keyless ignition vehicles emit an extremely low-power radio signal, looking for a matching fob that can respond. If the signal is captured and recreated, it can be used unlock the car, and also to start it.

Relay Attack

Imagine your car at your driveway, with your key fob inside your home. You're confident that your vehicle is safe, but not seen by you, sophisticated thieves are plotting a heist. Instead of slamming windows and jiggling locks, thieves are using technology to hack into vehicles using digital cracks in their armor. Also known as relay theft, it's a more common method of stealing vehicles that have keyless entry.

Cars equipped with keyless entry are designed to function using an electronic signal that is transmitted by the car's remote control (RF) transmitter to the owner's key fob. To prevent keyless entry by unauthorised persons the RF transmitters on the key fob as well as the car are programmed only to activate when they are within a specified distance from each other. A thief, however, can bypass this restriction by using a technique known as the'relay-attack'.

Two people are required to complete this: one stands close to the car and utilizes a device to capture digitally the the key fob. The other, standing by the house of the owner, uses a second device to transmit the key fob signal back to the car. This trick tricks the car into thinking that the key fob is near enough to unlock and start the engine.

In the past, this type of attack required expensive equipment to perform. Today, you can purchase an inexpensive relay transmitter online and pull off a heist within minutes. This is why car thieves love it.

While certain vehicles are less vulnerable to this type of theft than others, all cars that have keyless entry are at risk. In fact researchers have tested 237 popular vehicles and found that they could all be stolen using this method.

Tesla cars are said to be less prone to this kind of theft, however the company hasn't yet implemented UWB features to effectively perform distance checks on the car's signal to prevent relay attacks. The company has stated that they will implement this feature in the near future, but until then they are vulnerable. That's why it's essential to adopt a proactive approach to your security in your car and install an anti-theft tool which protects your keys as well as your vehicle from these kinds of attacks.

CAN Injection Attack

Modern cars can guard themselves from thieves by exchanging encrypted messages with the key in order to confirm its authenticity. This method is generally thought to be secure, but thieves have found a way around it. They fake the identity of the smart key, then send messages to the vehicle, and then drive off. To do this, they gain access to the smart keys' internal communications network.

Today, most automobiles are equipped with between 20 to 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate using a network called CAN bus. To reduce power consumption they ECUs go into the sleep mode at low power. This mode is activated when they receive a 'wake up frame. These frames are usually sent via the door or smart key receiver ECU. These messages aren't always authenticated or encrypted. This means that thieves can intercept them with the use of a cheap and simple device.

They search for a location that allows them to connect directly to the CAN connection wires. These are often hidden away within the headlights or in the front of the car and are accessible by pulling the bumper and cutting holes in the headlamp assembly to expose them. The thieves use a device known as a CAN injection attack to send out fake messages that 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 most major car manufacturers including BMW and Cadillac, Chrysler, Fiat and Ford, Honda, Hyundai and Jeep, Lexus and Nissan, Renault and Toyota, Volkswagen and Maserati. Researchers who discovered the CAN Injection attack recommend that all car manufacturers fix the issue in their current models. However, these thieves will continue to steal everything they can. We can stop this by implementing mechanical safety measures like Discloks in all our vehicles and parking them in well-lit, well-lit areas.

Blocking the Signal

In a different variant of the relay attack, thieves may make use of a device to block the signal from an electronic key fob if the vehicle is locked. The device could be hidden in the pocket or hidden place of a thief on the parking lot, or near the driveway that is being targeted. Once owners press the lock button on their fobs and walk away they don't consider whether or not their car is actually locks. Instead, thieves are able to escape with the vehicle because the signal that normally locks the car is blocked by the device of the criminal.

The crooks also employ devices to enhance the signal of the key fob in order to unlock vehicles. They can even accomplish this if the key is in the driver's pocket or hanging from its hook inside the house. When the car is unlocked, they can use a standard computer hacker to program an unlocked key fob to gain control over the vehicle.

Car manufacturers have come up with various anti-theft devices to safeguard against these types of attacks. But, as always, thieves come up with new ways to beat these measures.

For instance, they've begun using devices that transmit on the same frequency as remote key fobs to intercept their signals. The thieves then copy the unlock code from the key fob, and then start the vehicle using this fake signal.

This technique is especially popular in the US and Europe where a large number of automobiles are sold with wireless technology that lets owners unlock and start their cars using a mobile app on their phone. This technology is likely to become more popular as more car manufacturers attempt to connect their vehicles with their owners' smartphones.

In addition to incorporating anti-theft technology in vehicles, it's vital for drivers to use the best practices when parking their cars. They should never leave their keys in the ignition, and should always make sure the car is securely locked when they're not using it and should utilize a steering wheel or gearstick lock, if they can. It is also recommended to consider having a tracking device fitted to their car in the event it gets stolen.

Flat Battery

This kind of attack happens more often than we think. The thieves make use of low-cost devices that increase the signal from your key fob to enable it to unlock and start your car in the event that it is off. Then they drive the car to a trailer or around a corner, and take it away. It is possible to shield your vehicle from this by installing a starter circuit interrupt switch. Simpler versions have an ON/OFF button that shuts off the circuit. It is priced at around $15 and is easy to install.

Car thieves are always searching for new ways to take vehicles. The police, car makers and insurance companies are always trying to keep up with their strategies and offer better anti-theft solutions for the latest cars. However, that doesn't stop thieves, who are able to be quick to adapt and find ways to get around the most up-to-date anti-theft systems.

For instance, many criminals employ devices that operate on the same frequency as the fob in order to block the signal. The device is put in the pocket or close by the vehicle, and stops the fob from sending the signal to the car. This can be accomplished in a matter of seconds. The device is affordable and easily accessible on the internet.

Hacking the computer system of the car is another option. This is more difficult, but possible. Hackers have developed devices that plug into the diagnostic port of all cars and allow them to connect to the software. From there, they can program the blank key fob to make it work. This is also possible on older vehicles, read more but it is more difficult to do so without removing the ignition lock.

As more vehicles are linked to the phones of drivers, this method may be more popular. Once a burglar has access to the username and password to a vehicle application and is able to unlock or start the vehicle using the app. You can protect yourself by not leaving valuables in your car and by parking in a garage.
