Cars Being Stolen With Keyless Entry
Car owners who leave keys on tables or near their front doors may be unwittingly giving thieves the ability to take over the signal. This relay attack is a highly-tech technique used by criminals to steal keyless vehicles.
Keyless ignition vehicles emit a low-power radio signal in search of a fob to respond. If the signal is recorded and recreated, it can be used unlock the car and to start it.
Relay Attack
Imagine your car being parked safely in the driveway, and the key fob tucked away inside your home. You're confident that your vehicle is safe, but unnoticed by you, sophisticated thieves are plotting a heist. These thieves use technology to hack into vehicles via digital chinks. This method of stealing vehicles with keys is known as relay theft.
Cars equipped with keyless entry are designed to operate using signals that are sent from the remote control (RF) transmitter to the owner's key fob. To prevent keyless entry by unauthorized individuals the RF transmitters on the key fob as well as the car are programmed to turn on when they are within a certain distance from one another. A thief, however, can circumvent this limitation employing a technique called the "relay-attack".
To accomplish this two people work in tandem: one stands by the car with an instrument that records an electronic version of the key fob's signal. The other person, who is at the owner's home and uses a different device to transmit the signal from the key fob to the car. This trick tricked the car into thinking the key fob is near enough to unlock and start the engine.
This type of attack used to require expensive equipment. It is now possible to purchase a cheap relay transmitter online and carry out a heist within minutes. This is the reason why car thieves are enthralled by it.
All modern vehicles with keyless access are at risk. Some cars are more susceptible to this type of attack than others. Researchers have tested 237 of the most popular cars and found that every one of them could be taken through this method.
Tesla vehicles are said to be less vulnerable to this kind of theft. However Tesla hasn't yet implemented UWB technology that would allow it to conduct distance checks and prevent attacks via relay. The company has stated that they will implement this feature in the near future, but for now they are vulnerable. Installing an anti-theft system that safeguards your car and your keys against such a threat is a proactive approach to ensure the security of your vehicle.
CAN Injection Attack
Modern cars can protect themselves from theft by transferring encrypted messages using the key to confirm its authenticity. This system is generally reckoned to be secure, however thieves have found a way around it. They pretend to be a smart key, transmit messages to the vehicle, and then drive off. To accomplish this, they have access to the smart keys' internal communication network.
Nowadays, the majority of automobiles are equipped with between 20 and 200 electronic control units (or ECUs) that manage different aspects of the car's operation. They communicate using an electronic network known as CAN bus. To keep power consumption low the ECUs enter sleep mode with low power that is activated when they receive a 'wake up' frame. These frames are typically sent via the door or smart key receiver ECU. However, these messages aren't always encrypted or authenticated and, therefore, could be snatched by criminals using a cheap and basic device.
They look for a place that allows them to connect directly to the CAN connection 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 an instrument known as an CAN injection attack to send fake messages which can trick the security systems of the car into unlocking and disengaging the engine immobilizer.
These devices are for sale 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 address this in their existing models. However, these thieves will continue taking any opportunity they can. We can stop this from happening by installing mechanical safety measures such as Discloks in all of our cars and parking them in well-lit, visible areas.
Jamming the Signal
In a different variant of the relay attack, thieves could make use of a device to block the signal that is sent by the key fob when the car is locked. The device could be in the pocket or in the hiding the location of a thief in an open parking lot or even near the driveway being targeted. Owners don't check whether their vehicle is locked when they press the lock button. Instead, thieves could drive off with the vehicle since the signal that normally locks the car is blocked by the device of the criminal.
The crooks also use devices to amplify the signal from the key fob in order to unlock vehicles. The crooks can do this even if the key is in the driver's pocket or hanging on a hook inside the home. After the car has been unlocked, they can make use of the standard diagnostic port or computer hacker to program the blank key fob and gain control of the vehicle.
To protect against this type of attack, car makers have created a variety of anti-theft devices. But, thieves are constantly finding ways to beat 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 crooks then copy the unlock code from the key fob and begin the vehicle with this fake signal.
This technique is particularly popular in the US, where many cars are equipped with wireless technology. Owners can start and unlock their car through a mobile application from their mobile. This technique is likely to be more commonplace as more manufacturers try to connect their vehicles with their owners phones.
In addition to incorporating anti-theft technology in vehicles, it's important for drivers to leverage best practices when parking their cars. It is not advisable to leave the key fobs in ignition and secure the car when they are not in it. If they can it is also recommended to use a steering or gearstick locking device. They should also consider installing a tracking device to their car in case it gets stolen.
Flat Battery
This kind of attack happens more often than we think. The thieves make use of inexpensive devices that extend the signal from your key fob to unlock and start your car if it is off. Then they drive the vehicle to the trailer or around a corner to take the vehicle away. It would be possible to protect your vehicle from this by installing a starter circuit interrupt switch. Simpler versions include an ON/OFF button that interrupts the circuit. It costs around $15 and is easy to install.
Car thieves are always looking for new ways to rob vehicles. The police as well as the car makers and insurance companies are constantly trying to catch up with their strategies and offer better anti-theft solutions for modern cars. But that doesn't stop the thieves who are able to change quickly and discover ways to bypass the most up-to-date anti-theft systems.
For instance, a lot of criminals employ devices that operate on the same frequency as the fob to block the signal. They put the device in their pocket or close to their vehicle, and it prevents the fob's lock command from reaching the vehicle which leaves it unlocked. This can be done in a matter of minutes. The device is inexpensive and easily available on the internet.
Hacking the computer system of the car is another option. This is more difficult but nevertheless feasible. Hackers have developed devices that connect to the diagnostic port of all vehicles and allow them to access the software. From there, they are able to program an unfinished key fob and get it to work. It is also possible to do this on older vehicles, however it is more difficult to do without removing the ignition lock.
This method is likely to be more popular if more vehicles are connected to drivers' phones. Once a burglar has gained the username and password for an app for vehicles and then they can unlock or start the car using the app on their phone. You can safeguard yourself check here by not putting valuables in your car and parking in garages.
