Cars Being Stolen With Keyless Entry
Car owners who toss keys on tables or near their front doors could be allowing thieves to hijack the signal. This relay attack is one of the advanced methods criminals are using to steal brand new keyless vehicles.
All keyless ignition cars emit a low-power radio signal seeking a compatible fob that can 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 in your driveway, and your key fob in your home. You're sure that your car is safe, but unnoticed by you, sophisticated thieves are plotting a heist. The thieves employ technology to hack into vehicles via digital chinks. Known as relay theft, it's becoming a popular method of stealing cars with keyless entry.
Cars with keyless entry are designed to function using signals that are that is transmitted from the car's remote control (RF) transmitter to the owner's key fob. To prevent keyless entry 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 specified distance from one another. However, thieves are able to override this restriction using a technique called the 'relay attack'.
To do so, two people work in tandem one is positioned by the car with an instrument that records a digitized version of the key fob's signal. The other who is at home with the owner, uses a second gadget to transmit the signal from the key fob back to the car. This trick tricks the car into believing that the key fob has reached the distance needed to allow the vehicle to start and unlock. vehicle.
This type of heist used to require expensive equipment. Now, you can pick up a relay transmitter on the low cost online and conduct the heist in just a few minutes. This is why it's so popular among car thieves.
While certain cars are less prone to this type of theft than others, all modern vehicles that have keyless entry are vulnerable. In fact researchers have examined 237 popular vehicles and found that they could all be stolen using this method.
Tesla cars are said to be less vulnerable to this type of theft, however, the company hasn't yet implemented UWB features to effectively conduct distance checks on the car's signal to prevent relay attacks. The company has promised to implement this feature in the near future, but for now, they remain vulnerable. This is why it's crucial to be proactive about your car security and install an anti-theft tool which protects your keys as well as your the car from such attacks.
CAN Injection Attack
Modern vehicles are designed to guard themselves from thieves by transferring cryptographic messages using the key to prove it's genuine. This system is generally reckoned to be secure, however criminals have found a way to circumvent it. They impersonate a smart key, transmit messages to the vehicle, and then drive away. To accomplish this, they have access to the smart keys' internal communications network.
The majority of cars today are fitted with between 20 and over 200 electronic control units, or ECUs, that manage various aspects of the vehicle's operation. They communicate with each other using an electronic network referred to as 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 usually sent by the ECU that manages the smart key or door. These messages are not always authenticated or encrypted. This means that criminals can capture them using the use of a cheap and simple device.
To accomplish this, they search for a place that allows them to connect directly to the CAN bus wires. They are usually hidden in the headlights or in other areas of the front of the vehicle. To gain access to them, you must remove the bumper and make holes in the headlamp assemblies. The thieves use a device known as an CAN injection attack to send out fake messages that trick the car's safety systems into unlocking and disengaging the engine immobilizer.
The devices are available through the Dark Web and work with the majority of major car manufacturers including BMW and Cadillac, Chrysler, Fiat and Ford, Honda, Hyundai and Jeep, Lexus and Nissan, Renault and Toyota, Volkswagen and Maserati. The researchers who discovered this CAN Injection attack are recommending that all car manufacturers fix the issue in their current models, but the reality is that thieves will continue to grab everything they can lay their hands on. The best thing we can do is to make an effort to prevent this from happening by putting in mechanical security measures like Discloks on our cars, and making sure that they're always placed in areas that are well-lit and are clearly visible to people passing by.
The Signal is blocked
In a variation of the relay attack, which employs a device, thieves can jam the signal from key fobs while the car is locked. The device could be hidden in the pocket of a thief in a parking lot or in a hiding spot close to the driveway that is being targeted. Owners aren't able to verify whether here the vehicle is locked when they press the lock button. The device of the crook block the signal that locks the vehicle. Therefore, thieves can drive away with the vehicle.
They also have devices that amplify signals from the key fob to unlock vehicles. They can accomplish this if the key is in the pocket of the driver or hanging from a hook in the home. Once the car is locked, they can use a standard diagnostic port or computer hacker to program the blank key fob and gain control of the vehicle.
Automobile manufacturers have developed a range of anti-theft systems to guard against these kinds of attacks. However, thieves are always looking for ways to defeat these measures.
They've started using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The thieves can then copy the key fob's unlock code and then start the car using this fake signal.
This technique is especially popular in the US and Europe where a lot of automobiles are sold with wireless technology that lets owners unlock and start their vehicles with a mobile app on their smartphone. This technique is likely to become more popular as more manufacturers try to connect their cars to their owners smartphones.
It is important that drivers follow the best practices when parking their vehicles. They should never leave the key fobs in ignition and always secure the car when not in it. If they can, they should also use a gearstick lock or steering device. It is also recommended to consider having a tracking device fitted to their vehicle in the event that it's stolen.
Flat Battery
This kind of attack is more common than most people realize. Thieves employ cheap devices to extend the signal from your key fob to open and start the car, even if it's switched off. Then they drive the car to the trailer or around a corner, and take the vehicle away. Installing a starter circuit interruption switch can protect your vehicle from this. Simpler versions include an ON/OFF button which interrupts the circuit. It costs around $15 and is easy to install.
Car thieves are always looking for new ways to enter vehicles and steal them. The police as well as car manufacturers and insurance companies are always trying to keep up with their strategies and offer better anti-theft solutions for modern cars. But this isn't stopping thieves who be quick to adapt and find ways to bypass the latest anti theft measures.
Many thieves block the signal using a device that uses the same radio frequency of the fob. The device is put in the pocket or close to the vehicle and blocks the fob from transmitting the lock command to the car. This can be done within minutes. The device is affordable and is available on the internet.
Another option is to hack into the car's computer system. This is more difficult but still possible. All cars have a diagnostic port, and hackers have developed devices that plug into them and let them access the software in the car. From there, they can program an unfinished key fob and start working. This can also be done on older vehicles, however it is more difficult to do so without removal of the ignition lock.
This method could be more popular if more vehicles are connected with drivers' mobile phones. Once a criminal has access to the username and password to a vehicle app and is able to unlock or start the vehicle using the application. You can safeguard yourself by not leaving valuables in your car and by parking in garages.
