Cars Being Stolen With Keyless Entry
Car owners who toss keys on tables or near their front door could be allowing thieves to hijack the signal. This relay attack is a sophisticated method used by criminals to steal keyless vehicles.
Keyless ignition vehicles emit an extremely low-power radio signal, looking for a matching fob to respond. If the signal can be captured and recreated, it could be used unlock the car, and also to start it.
Relay Attack
Imagine your car safely at your driveway, with your key fob in your home. You're sure that your car is safe, but unnoticed by you sophisticated thieves are planning an attack. The thieves employ technology to hack into vehicles via digital chinks. This method of stealing cars that have keyless access is known as relay theft.
The keyless entry system in cars is controlled by a signal by the car's RF transmitter to the key fob. To prevent unauthorized keyless entry, the RF transmitters in the key fob and in the car are programmed to activate only when they're within a certain 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 together one is positioned by the car with an instrument that records a digitized version of the key fob's signal. The other, in the vicinity of the house of the owner, uses a second device to send the key fob signal back down to the car. This trick tricks the car into thinking that the key fob has traveled the distance needed to allow the vehicle to start and unlock. vehicle.
In the past, this kind of attack required expensive equipment to carry out. However, now you can pick up a relay transmitter on the inexpensive online market and carry out a heist in minutes. This is the reason it's popular with car thieves.
All modern vehicles with keys are at risk. Certain vehicles are more vulnerable to this type of attack than others. Researchers have tested 237 of the most popular cars and found that every one of them can be stolen using this method.
Tesla vehicles are said to be less vulnerable to this kind of theft. However, the company hasn't yet implemented UWB technology that would enable it to perform distance checks and prevent relay attacks. The company has stated that they will make this happen in the near future, but until then they are vulnerable. Installing an anti-theft system that protects both your car keys and your keys against these types of attacks is a proactive method to ensure the security of your car.
CAN Injection Attack
Modern cars can protect themselves from thieves by sending encrypted messages to the key to prove its authenticity. The system is considered to be secure, but thieves have found ways around it. They can pretend to be the smart key and send other messages to the vehicle letting it unlock the doors, turn off its engine immobilizer, then let them go on their way. To do this, they get access to the smart key's internal communication network.
Today, 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 through a network called CAN bus. To ensure that power consumption is low they ECUs are put into the sleep mode at low power. This mode is activated when they receive a 'wake up' frame. These frames are typically sent from the door or smart key receiver ECU. These messages aren't always authenticated or encrypted. This means that criminals can capture them using a simple and cheap device.
They search for a location where they can connect directly to the wires for CAN connection. They are usually hidden 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 use a device known as a CAN injection attack to send fake messages that fool the safety systems of the car to unlock and disable the engine immobilizer.
These devices are for purchase on the Dark Web, and work for the majority of major car manufacturers, including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and many more. Researchers who discovered the CAN Injection attack recommend that all car makers fix the issue in their current models. However, the thieves will continue to steal everything they can. The best thing we can do is to try and prevent this by putting in mechanical security measures like Discloks on all our vehicles and ensuring that they're always placed in areas that are well-lit and are clearly visible to passers-by.
Jamming the Signal
In a variation of the relay attack that makes use of a device, thieves can jam the signal sent by a key fob while the vehicle is locked. The device could be in the pocket of a burglar in a parking area or in a hiding spot close to the driveway that is being targeted. Owners don't check whether their vehicle is locked 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 device of the criminal.
The more info crooks also make use of devices to amplify the signal from the key fob in order to unlock vehicles. The crooks can do this even when the key is in the pocket of a driver, or hanging from a hook inside the home. Once the car has been locked, hackers can use the standard diagnostic port to program a blank fob.
Automobile manufacturers have developed a range of anti-theft systems to protect against these types of attacks. However, thieves will always find ways to defeat 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 key fob's unlock code and then start the car with this fake signal.
This method is particularly popular in the US and Europe where a large number of cars are sold with wireless technology that lets owners unlock and start their vehicle with a mobile app on their smartphone. This technique is likely to increase in popularity as more car manufacturers attempt to connect their cars to their owners phones.
It is important that drivers follow the right procedures when parking their vehicles. They should not leave their keys in the ignition and should always lock the car when not in it. If possible they should also utilize a steering or gearstick locking device. They should also consider fitting a tracking device to their vehicle in the event it's stolen.
Flat Battery
This kind of attack is more prevalent than most people realize. Thieves employ cheap devices to extend the signal from your key fob to unlock and begin a car even when it's switched off. Then they drive the car to an unmarked trailer or around a corner and take it away. It is possible to protect your car from this by installing an interrupter for the starter circuit. The simplest ones just have an ON/OFF switch which interrupts the starter circuit. It's priced at around $15 and is simple enough to put in yourself.
Car thieves are always seeking new ways to steal vehicles. Car manufacturers, police and insurance companies are always trying to keep up with the latest methods and offer better anti theft systems for modern vehicles. However, that doesn't stop thieves who are able to adapt quickly and discover ways to bypass the latest anti-theft measures.
For example, many criminals employ devices that operate on the same radio frequency as the fob in order to block the signal. The device is put in the pocket or near the vehicle and prevents the fob from sending the signal to the car. This can be accomplished in just a few seconds. The device is affordable and easily accessible on the internet.
Hacking the computer system of the car is an alternative option. This is more difficult but still possible. Every car has an diagnostic port and hackers have developed devices that plug into them and let them access the car's software. They can then program a blank fob to function. It is possible to do this on older cars also, but it's more difficult without taking out the ignition.
As more vehicles are linked to drivers' phones and this method could become more popular as well. Once a burglar has access to the username and password to a vehicle app they can open or start the vehicle by using the app. Fortunately, you can be safe from these kinds of attacks by not putting valuables in your car and putting it in a garage or secure parking lot.
