Cars Being Stolen With Keyless Entry
Car owners who toss their keys on tables or in front of their front door may be unwittingly giving thieves the ability to take over the signal. This relay attack is a high-tech technique used by criminals to steal keys from new vehicles.
All keyless ignition cars emit an low-power radio signal that is seeking a compatible fob that can respond. If the signal is recorded and recreated, it could be used to unlock the car and begin it up.
Relay Attack
Picture your car parked securely in your driveway, with the key fob safely in your home. You might think that your car is safe but sophisticated thieves are planning a heist, without you even knowing. Instead of breaking windows or jimmying locks, thieves are leveraging technology to hack into cars via digital chinks in their armor. This method of stealing cars that have keyless access is called relay theft.
Cars with keyless entry are designed to operate via a signal sent by the car's remote control (RF) transmitter to the owner's key fob. To stop unauthorized keyless entry the RF transmitters inside the key fob and in the car are programmed to activate only when they're within a specific distance of each other. The thief can circumvent this limitation employing a method known as the'relay-attack'.
To accomplish this two people work in tandem one is positioned by the car, using a device that captures digitally the key fob's signal. The other who is at home with the owner is using a second device to transmit the signal from the key fob back to the car. This trickery fools the car into thinking the key fob is close enough to unlock and begin the engine.
This kind of heist used to require expensive equipment. However, now you can buy relay transmitters on the inexpensive online market and carry out a heist in minutes. This is why it's so well-liked by car thieves.
While some cars are less prone to this type of theft than others, all modern cars that have keyless entry are vulnerable. In fact researchers have tested 237 vehicles that are popular and found that they can be all stolen using this method.
Tesla cars are said to be less susceptible to this type of theft, however Tesla hasn't yet implemented UWB features that could effectively perform distance checks on the car's signal and prevent relay attacks. The company has promised to make this happen in the near future, but for now they are vulnerable. Installing an anti-theft device that guards your car and your keys against these types of attacks is a proactive method to ensure your car's security.
CAN Injection Attack
Modern vehicles are designed to protect themselves from theft by exchanging cryptographic data with the key to prove it's genuine. This method is generally thought to be secure, however criminals have found a way around it. They impersonate the smart key, then send messages to the vehicle and then drive away. To do that, they get access to the smart key's internal communications network.
Today, most cars are equipped with between 20 and 200 electronic control units, or ECUs, that control different aspects of the vehicle's operation. They communicate with one another using a network known as CAN bus. To ensure that power consumption is low the ECUs enter sleep mode with low power that is activated when they receive a 'wake up frame. These frames are typically sent by the ECU that is in charge of the smart key or door. However, these messages aren't always authenticated or encrypted and, therefore, can be intercepted by criminals with a cheap and simple device.
They search for a location that allows them to connect directly to the CAN connection wires. They usually are hidden in the headlights or in other locations in the front of the vehicle. To gain access to them, you must remove the bumper and make holes in the headlamp assemblies. The criminals then employ a device dubbed an CAN injection attacker to send out fake messages that trick the car's security systems to unlock it and disable its engine immobilizer.
These devices are for purchase on the Dark Web, and work for the majority of major car manufacturers which include 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 address this in their existing models. However, the thieves will continue to steal whatever they can. The best thing we can do is to make an effort to prevent this from happening by installing mechanical security measures such as Discloks on all of our cars and ensuring that they are located in areas with adequate lighting that are clearly visible to passers-by.
The Signal is blocked
In a variant different to the relay attack, thieves can make use of a device to block the signal from a key fob when the vehicle get more info is locked. The device may be hidden in the pocket of a burglar in a parking area or in a hiding spot near the driveway being targeted. Owners aren't able to verify whether their vehicle is locked after pressing the lock button. Instead, thieves can take off with the car since 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. They can accomplish this if the key is in the driver's pocket or hanging from a hook inside the house. After the car is unlocked, hackers can make use of an ordinary diagnosis port to create an unlocked fob.
Automobile manufacturers have come up with a range of anti-theft systems to guard against these kinds of attacks. But thieves always find ways to defeat these measures.
For instance, they've been using devices that transmit on the same radio frequency as remote key fobs in order to intercept their signals. The thieves can then copy the key fob's unlock code and start the car with this fake signal.
This technique is especially popular in the US and Europe where many automobiles are sold with wireless technology that allows owners to unlock and start their cars by using a mobile application from their phones. This technique is likely to increase in popularity as more companies attempt to connect their vehicles with their owners' smartphones.
In addition to installing anti-theft technologies in vehicles, it's crucial for drivers to use the best practices when they park their cars. They should never leave the keys in ignition and should always lock the car when not in it. If they can, they should also use a steering or gearstick locking device. It is also recommended to think about fitting a tracking device to their vehicle in the event that it is stolen.
Flat Battery
This type of attack is more frequent than people think. Thieves make use of cheap devices to extend the signal from your key fob to unlock and begin the car, even if it's turned off. They then simply drive the car around the corner or onto a trailer to leave with it. Installing an interruption switch to the starter circuit will protect your vehicle from this. The simplest ones are an ON/OFF switch that shuts off the starter circuit. It's about $15 and is easy to install.
Car thieves are always seeking new ways to steal vehicles. The police, car makers and insurance companies are always trying to keep up to their tactics and provide better anti-theft systems for the latest cars. But that doesn't stop the thieves, who are able to adapt quickly and find ways to circumvent the most recent anti-theft measures.
For instance, a lot of thieves use a device that works on the same frequency as the fob in order to block the signal. They put the device in their pockets or somewhere near their vehicle, and it prevents the fob's lock signal from reaching the vehicle which leaves it unlocked. This can be done in a matter of minutes. The device is affordable and is available online.
Another option is to hack into the car's computer system. This is more difficult but possible. Hackers have created devices that plug into the diagnostic port of all vehicles and allow them to connect to the software. From there, they are able to program the blank key fob to get it to work. This is also possible on older vehicles, but it is more difficult without removing the ignition lock.
This technique could be more popular if more vehicles are connected with drivers' phones. Once a burglar has the username and password to a vehicle app they can open or start the vehicle using the application. Fortunately, you can protect yourself from these types of attacks by not putting valuables in your car and parking it in a garage or secured parking lot.
