Cars Being Stolen With Keyless Entry
Car owners who throw their keys on a table or near their front doors may be unwittingly allowing thieves to hijack the signal. This relay attack is a highly-tech technique used by criminals to steal keyless vehicles.
Keyless ignition vehicles emit an extremely low-power radio signal, in search of a fob that can respond. If the signal is captured and recreated it can be used to unlock the car and then start it up.
Relay Attack
Imagine your car safely parked in your driveway with your key fob in your home. You're confident that your vehicle is safe, but unnoticed by you sophisticated thieves are planning an attack. Instead of breaking windows or jimmying locks, these thieves are using technology to hack into cars via digital chinks in their armor. This method of stealing cars that have keys is known as relay theft.
The keyless entry system that is found in cars is controlled by a signal by the car's RF transmitter to the key fob. To prevent keyless entry by unauthorized individuals, the RF transmitters on the key fob and the car are programmed to be activated when they are within a specific distance from one another. However, thieves are able to bypass this limitation with a technique known as the'relay attack'.
To accomplish this, two people work together one is positioned by the car, using the device that captures digitally the key fob's signal. The other who is at the home of the owner is using a second device to transmit the signal from the key fob back to the car. This trickery tricks the car into believing that the key fob is at an adequate distance to allow the vehicle to start and unlock. vehicle.
In the past, this type of attack required expensive equipment to perform. But now, you can pick up a relay transmitter on the inexpensive online market and carry out a heist in minutes. This is why car thieves are enthralled by it.
While some cars are less vulnerable to this kind of theft than others, all cars with 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 vehicles are supposedly less prone to this kind of theft, but the company hasn't yet implemented UWB features that would effectively conduct distance checks on the car's signal to stop relay attacks. The company has said it will make this happen in the near future, but for now, they remain vulnerable. This is why it's crucial to take a proactive approach to your car security and install an anti-theft device that safeguards your keys and car from these types of attacks.
CAN Injection Attack
Modern vehicles can defend themselves from theft by transferring encrypted messages using the key in order to confirm its authenticity. The system is generally believed to be secure, however thieves have found a way around it. They pretend to be the smart key, then send messages to the vehicle, and then drive away. To do this, they gain access to the smart keys' internal communication network.
Today, most automobiles are equipped with between 20 and 200 electronic control units (or ECUs) that control various aspects of the car's operation. They communicate with each other via an electronic network referred to as CAN bus. To ensure that power consumption is low, these ECUs enter a low-power sleep mode that's activated when they receive a 'wake up' frame. These frames are usually sent through the door or a smart key receiver ECU. However the messages aren't usually encrypted or authenticated and, therefore, could be snatched by criminals using a cheap and basic device.
To accomplish this, they search for a location that allows them to connect directly to the CAN bus connector wires. These are often hidden away inside the headlights or elsewhere in the front of the vehicle, and are accessible by pulling the bumper off and cutting holes in the headlamp assembly to expose them. The thieves employ an instrument 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 are available for sale 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. The researchers who discovered this CAN Injection attack are recommending that all car makers fix the issue in their current models, but the fact is that the thieves will continue to take anything they can get their hands on. We can stop this by implementing mechanical safety measures, such as Discloks inside every car we own and parking them in well-lit, well-lit areas.
The Signal is blocked
In a different variant of the relay attack, thieves can employ a device to block the signal from an electronic key fob if the car is locked. The device could be found in the pocket of a thief in a parking space or in a hiding spot close to the driveway that is being targeted. Once owners hit the lock button on their fobs, and then walk away they don't consider whether or not the car is really is locked. The device used by the criminal block the signal that locks the vehicle. Therefore, thieves could escape with the car.
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 make use of an ordinary diagnosis port to program the fob with a blank.
Automobile manufacturers have come up with a variety of anti-theft solutions to guard against these kinds of attacks. But, thieves are constantly trying to beat these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs to intercept signals. The thieves then copy the unlock code of the key fob and start the vehicle using this fake signal.
This method is very 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 with a mobile app from their phones. This technology is expected to become more popular as more and more manufacturers attempt to connect their vehicles with their owner's smartphones.
In addition to implementing anti-theft systems in vehicles, it's crucial for drivers to follow the best practices when they park their vehicles. They should not leave their keys in the ignition and lock the car when not in it. If possible, they should also use a steering or gearstick locking device. It is also recommended to think about installing a tracking device on their vehicle in the event it's stolen.
Flat Battery
This kind of attack is more frequent than most people realize. Thieves make use of inexpensive devices to extend the signal from your key fob to unlock and begin cars even if they're shut off. Then they drive the car to an unmarked trailer or around a corner, and take the car away. Installing an interrupter switch for the starter circuit would protect your car against this. The simplest ones are an ON/OFF switch that shuts off the starter circuit. It's priced at around $15 and is simple enough to put in yourself.
Car thieves are always looking for new ways to gain access to vehicles and take them away. The police as well as car manufacturers and insurance companies are constantly trying to catch up with their strategies and develop better anti-theft systems for modern vehicles. But this doesn't stop thieves who can easily adapt and find ways to circumvent the latest anti-theft technology.
For instance, a lot of thieves use a device that works on the same frequency as the fob to jam the signal. They place the device in their pockets or somewhere close to their vehicle, and it stops the fob's lock command from reaching the car and thereby leaving it unlocked. This can be done in a matter of seconds. The device is cheap and available on the internet.
Another tactic is to hack into the car's computer system. This is more difficult but possible. All cars have an diagnostic port and check here hackers have created devices that plug into them and let them access the car's software. From there, they are able to program an unfinished key fob and start working. This can also be done on older vehicles, but it is more difficult to do so without removal of the ignition lock.
This technique could be more popular if more vehicles are connected to drivers' mobile phones. Once a thief gets the username and password for the vehicle app, they can then open the car or get it started by using the app on their phone. It is possible to be safe from these kinds of attacks by not leaving valuables in your car, and then parking it in a secure garage or parking lot.
