Cars Being Stolen With Keyless Entry

Car owners who throw keys on tables or in front of their front door may be unwittingly allowing thieves to hijack the signal. This relay attack is a highly-tech method criminals use to steal new keyless vehicles.

All keyless ignition cars emit an low-power radio signal that is in search of a fob to respond. 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 parked in your driveway with your key fob in your home. You may think your car is safe however, sophisticated thieves are planning to steal your car without you even knowing. Instead of slamming windows and jiggling locks, these thieves are leveraging technology to hack into vehicles using digital chinks in their armor. This method of stealing cars with keyless access is known as relay theft.

The keyless entry system in cars is controlled by a signal sent from the car's RF transmitter to the key fob. To ensure that keyless entry is not accessed 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 specific distance from each other. However, a thief can bypass this limitation with an attack known as the'relay attack'.

To do so two people work in tandem One stands near the car and uses the device that captures a digitized version of the key fob's signal. The other, in the vicinity of the house of the owner and using a second device to transmit the key fob's signal to the car. This trick tricks the car into believing that the key fob is at a distance sufficient to allow it to be opened and started the vehicle.

This kind of heist used to require expensive equipment. You can now buy a cheap relay transmitter on the internet and complete a heist within minutes. This is the reason car thieves are enthralled by it.

All modern vehicles that have keys are at risk. Certain cars are more susceptible to this kind of attack than others. Researchers have examined 237 well-known automobiles and found that all of them could be taken by this method.

Tesla vehicles are believed to be less vulnerable to this kind of theft. However Tesla hasn't implemented UWB technologies that would enable it to perform distance checks and stop relay attacks. The company has stated that they will implement this in the future but until then they are vulnerable. This is why it's crucial to be proactive about your security in your car and install an anti-theft tool that protects your keys and car from these types of attacks.

CAN Injection Attack

Modern cars can guard themselves from thieves by exchanging encrypted messages with the key to prove its authenticity. This system is generally reckoned to be secure, however 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 communication network.

Today, most cars are equipped with between 20 and 200 electronic control units, also known as ECUs, which control various aspects of the vehicle's operation. They communicate with one another using the CAN bus. To keep power consumption low the ECUs are put into sleep mode with low power that is activated when they receive a 'wake up frame. These frames are typically sent from the door or smart key receiver ECU. These messages are not always authenticated or encrypted. This means that thieves can capture them using the use of a cheap and simple device.

To do this, they look for a spot where they can directly connect to the CAN bus wires. These are often hidden away within the headlights or in the front of the vehicle, and are accessible by pulling the bumper off and cutting holes in the headlamp assembly to expose the wires. The thieves employ the device referred to as an CAN injection attack to send fake messages which can trick the security systems of the car to unlock and disable the engine immobilizer.

The devices are available on the Dark Web and work with the majority of major car manufacturers which include BMW and Cadillac, Chrysler, Fiat and Ford, Honda, Hyundai and Jeep, Lexus and Nissan, Renault and Toyota, Volkswagen and Maserati. Researchers who have discovered the CAN Injection attack recommend that all car makers fix this issue in their existing models. However, these thieves will continue to take everything they can. We can stop this by installing mechanical security measures such as Discloks in all of our cars and parking them in well-lit, well-lit areas.

Blocking the Signal

In a variant different to the relay attack, thieves may employ a device to block the signal that is sent by a key fob when the vehicle is locked. The device could be found in the pocket or hidden place of a thief on a parking lot, or near the driveway that is being targeted. When owners hit the button to lock their fobs and leave, they don't think about 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 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. They may even accomplish this if the key is in the pocket of the driver or hanging from its hook inside the house. After the car is unlocked, hackers can use an ordinary diagnosis port to program a blank fob.

Automobile manufacturers have come up with a variety of anti-theft solutions to guard against these kinds of attacks. However, criminals are constantly looking for ways to defeat these measures.

For example, they've started using devices that transmit on the same frequency as remote key fobs in order to intercept their signals. The crooks then copy the unlock code of the key fob and then start the car with this fake signal.

This method is particularly popular in the US and Europe where a large number of vehicles are sold with wireless technology that allows owners to unlock and start their vehicles using a mobile app on their phone. This technology is expected to gain popularity as more and more manufacturers try to connect their vehicles to their owners' smartphones.

It is important that drivers use best practices when parking their vehicles. They shouldn't leave their key fobs in the ignition. They should always make sure the car is securely locked when they're not there and should use the steering wheel or a gearstick lock if possible. They should also think about installing a tracking device on their vehicle in the event that it is deactivate stolen car key fob.

Flat Battery

This type of attack occurs more often than most people realize. The thieves make use of inexpensive devices that extend the signal from your key fob to enable it to unlock and start your car even when it's off. They then simply drive the car around the corner or onto a trailer to take off with it. Installing a starter circuit interruption switch would protect your my car keys were stolen against this. 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 working on new ways to gain access to vehicles and take them away. The police as well as the car makers and insurance companies are constantly trying to keep up to their tactics and provide better anti-theft systems for modern cars. However, that doesn't stop thieves who are able to be quick to adapt and find ways to get around the latest anti-theft measures.

For instance, many criminals use devices that operate on the same radio frequency as the fob to jam the signal. The device is put in the pocket or near the vehicle, and stops the fob from transmitting the lock command to the vehicle. This can be done in a matter of seconds. The device is cheap and is available online.

Hacking the computer system of the car is another option. This is more difficult, but nevertheless feasible. Every car has an diagnostic port, and hackers have created devices that plug into them and let them access the car's software. They can then program the fob with blank code to function. It is possible to do this on older cars too however it is more difficult without taking out the ignition.

This method could become more popular as more vehicles are connected to drivers' phones. Once a criminal has the username and password to the vehicle app they are able to unlock or start the car keys stolen from unlocked house by using the app on their phone. You can guard yourself by not putting valuables in your car and also by parking in garages.
