Cars Being Stolen With Keyless Entry
Car owners who throw their keys on tables or in front of their front door may be unwittingly allowing thieves to hijack the signal. This relay attack is a sophisticated method used by criminals to steal keys from new vehicles.
Keyless ignition vehicles emit a low-power radio signal in search of a fob that can respond. If the signal can be captured and recreated, it can be used unlock the car, and also to start it.
Relay Attack
Imagine your car safely parked in the driveway, and the key fob sitting safely in your home. You're sure that your car is safe, but unnoticed by you, sophisticated thieves are plotting an attack. Instead of slamming windows and jiggling locks, they are leveraging technology to hack into cars via digital cracks in their armor. This is known as relay theft, it's a more popular method of stealing cars with keyless entry.
Cars with keyless entry are designed to operate via signals that are 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 on the key fob and the car are programmed only to activate when they are within a certain distance from one another. A thief, however, can circumvent this limitation using a technique known as the "relay-attack".
Two individuals are required to perform this: one person is close to the car and uses a device that captures an electronic version of the signal coming from the key fob. The other person, who is at home with the owner, uses a second gadget to transmit the signal from the key fob back to the car. This trickery tricks the car into believing the key fob has traveled a distance sufficient to allow it to be opened and started the vehicle.
In the past, this kind of attack required expensive equipment in order to execute. However, now you can pick up relay transmitters for inexpensive online market and carry out the heist in just a few minutes. This is why car thieves are enthralled by it.
All modern vehicles that have keys are at risk. Some cars are more vulnerable to this type than others. In fact, researchers have tested 237 vehicles that are popular and found that they can all be stolen using this method.
Tesla vehicles are believed to be less prone to this kind of theft, however, the company has not 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 implement this in the near future, but until then, they are vulnerable. That's why it's essential to take a proactive approach to your security in your car and install an anti-theft kit that protects your keys and car from these types of attacks.
CAN Injection Attack
Modern cars can guard themselves from thieves by transferring encrypted messages using the key in order to prove its authenticity. The system is considered to be secure, but criminals have found ways to circumvent it. They simply pretend to be the smart key and send other messages to the car letting it unlock the doors, disable its engine immobilizer, and then go on their way. To accomplish this, they have access to the smart keys' internal communication network.
Today, most cars are equipped with between 20 and over 200 electronic control units, also known as ECUs, that control different aspects of the vehicle's operation. They communicate with each other using an electronic network referred to as CAN bus. These ECUs are put into a low power sleep mode to decrease their power consumption. This mode is activated when the ECUs receive a "wake up" frame. These frames are usually sent by the ECU that manages the smart key or door. However the messages aren't usually encrypted or authenticated and, therefore, can be intercepted by criminals using a cheap and simple device.
They search for a spot where they can connect directly to the CAN connection wires. These are often hidden away within the headlights or in front of the car, and are accessible by removing the bumper and cutting holes in the headlamp assembly to expose the wires. The thieves then use a device called a CAN injection attacker to send out fake messages that fool the security systems of the car into unlocking the car and disengaging the engine immobilizer.
These devices are available for purchase on the Dark Web, and work for most of the major car makers, including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and many more. Researchers who have discovered the CAN Injection attack recommend that all car makers fix this in their existing models. However, these thieves will continue taking any opportunity they can. The best we can do is to try and prevent this by putting in mechanical security measures like Discloks on our cars and ensuring that they are always placed in areas that are well-lit and are clearly visible to passers-by.
The Signal is blocked
In a variant of the relay attack, which uses a gadget that is able to block the signal sent by the key fob when the vehicle is locked. The device could be in the pocket or hiding the location of a thief in the parking lot, or near the driveway being targeted. Owners aren't able to verify whether their vehicle is locked when they press the lock button. Instead, thieves can escape with the vehicle because the signal that normally locks the car has been blocked by the crook's device.
The crooks also use devices to enhance the signal of the key fob in order to unlock vehicles. They can even do this when the key is in the driver's pocket or hanging from its hook in the house. After the car is unlocked, hackers can use an ordinary diagnosis port to program the fob with a blank.
To safeguard against this kind of attack, car makers have developed a variety of anti-theft gadgets. But thieves always come up with new ways to beat these measures.
For example, they've started using devices that transmit on the same frequency as remote key fobs to intercept their signals. The crooks can then copy the key fob's unlock code and start the car with this fake signal.
This method is particularly popular in the US and Europe where a lot of vehicles are equipped with wireless technology that allows owners to unlock and start their vehicle with a mobile app on their phone. This technology is likely to become increasingly popular as more and more manufacturers try to connect their vehicles with their owner's smartphones.
It is essential that drivers use best practices to park their cars. They should never leave the key fobs in ignition and should always secure the car when they are not in it. If they can it is also recommended to use a gearstick lock or steering device. It is also recommended to consider having a tracking device fitted to their car in the event it is stolen.
Flat Battery
This kind of attack happens more often than we think. The thieves use cheap devices that extend the signal of your key fob in order to unlock and start your car in the event that it is off. Then, they drive the car to the trailer or around a corner and take it away. It would be possible to protect your car from this by installing a starter circuit interrupt switch. The simplest ones just have an ON/OFF switch that shuts off the starter circuit. It costs around $15 and is simple to install.
Car thieves are always trying new ways to get into vehicles and take them away. Police, car manufacturers and insurance companies are constantly trying to stay abreast of the latest techniques and offer better anti theft systems for modern vehicles. But that doesn't stop thieves who are able adapt quickly and find ways to circumvent the most up-to-date anti-theft systems.
A lot of thieves block the signal using devices that use the same radio frequency as the fob. They put the device in their pocket or somewhere close to their vehicle, and it blocks the fob's lock command from reaching the vehicle which leaves the vehicle unlocked. This can be accomplished in a matter of minutes. The device is cheap and readily available on the internet.
Hacking the computer system of the car is another option. This is harder but still feasible. 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 the blank key fob to get it to work. It is possible to do this on older vehicles as well but it's more difficult if you remove the ignition.
As more vehicles are connected to the phones of drivers the method is likely to become more popular too. Once get more info a criminal has access to the username and password to a vehicle app and is able to unlock or start the vehicle using the app. You can guard yourself by not leaving valuables inside your car, and by parking in garages.
