Cars Being Stolen With Keyless Entry
If car owners leave their keys on the table or next to their doors, they could not realize that they are allowing thieves to steal their signal. This relay attack is one of the high-tech methods criminals are using to steal brand new keyless vehicles.
Keyless ignition vehicles emit a low-power radio signal to find an appropriate fob. 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 at your driveway, with your key fob at home. You're sure that your car is safe, but not seen by you sophisticated thieves are planning a heist. Instead of slamming windows and jiggling locks, thieves are leveraging technology to hack into vehicles using digital chinks in their armor. This method of stealing vehicles with keyless access is called relay theft.
The keyless entry system found in cars is controlled by a signal from the car's RF transmitter to the key fob. To ensure that keyless entry is not unauthorized the RF transmitters inside the key fob and in the car are programmed to only be activated when they're within a certain distance from each other. However, a thief can overcome this limitation using a technique called the 'relay attack'.
Two people are required to complete this: one stands near the car and uses a device to capture a digitalized version of the signal from the key fob. The other, who is at the home of the owner, uses a second gadget to transmit the signal from the key fob to the car. This trick tricked the car into thinking that the key fob is close enough to allow it to unlock and begin the engine.
This kind of heist was once a costly process that required expensive equipment. You can now buy a cheap relay transmitter online and pull off an heist in just a few minutes. This is why car thieves love it.
All modern vehicles with keys are at risk. Some cars are more susceptible to this type than others. Researchers have examined 237 well-known cars and found that every one of them are susceptible to being stolen by this method.
Tesla vehicles are believed to be less vulnerable to this kind of theft. However Tesla hasn't yet implemented UWB technology to enable it to perform distance checks and prevent attacks via relay. The company has said it will implement this feature in the near future, but for now they are still vulnerable. Installing an anti-theft system that safeguards your car keys and your keys against such attacks is a proactive method to ensure the security of your car.
CAN Injection Attack
Modern vehicles are designed to protect themselves from thieves by exchanging cryptographic data with the key to prove that it's authentic. The system is believed to be safe, but thieves have found ways around it. They just pretend to be the smart key and send messages to the car, letting it unlock the doors, disable its engine immobilizer, and let them drive away. To do that they have access to the smart key's internal communication network.
Nowadays, the majority of cars are equipped with between 20 and 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate via an electronic network known as CAN bus. These ECUs enter a low power sleep mode to reduce their power consumption. This mode is activated when ECUs receive an "wake up" frame. These frames are typically sent through the door or a smart key receiver ECU. However they aren't always authenticated or encrypted so they could be snatched by criminals with a cheap and simple device.
To do this, they look for a spot that allows them to connect directly to the CAN bus wires. They're usually hidden inside the headlights or elsewhere in front of the vehicle, and can be accessed by pulling the bumper and cutting holes in the headlamp assembly to expose the wires. The thieves use an instrument known as an CAN injection attack to send out fake messages that fool the safety systems of the car into unlocking and disengaging the engine immobilizer.
The devices are available on the Dark Web and work with most 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 makers address it in their existing models, but the fact is that the thieves will continue to grab whatever they can get their hands on. The best we can do is to try and prevent this by installing security measures that are mechanical such as Discloks on all of our vehicles, and making sure that they're always located in areas with adequate lighting that are clearly visible to people passing by.
The Signal is blocked
In a different variant of the relay attack, thieves could employ a device to block the signal sent from the key fob when the car is locked. The device may be in the pocket of a burglar in a parking space or in a hidden spot near the driveway being targeted. The owners don't know if the car is locked after pressing the lock button. The device used by the crook block the signal that locks the vehicle. Therefore, thieves can leave the vehicle.
They also have devices that amplify signals from the key fob to unlock vehicles. They can even do this while the key is in the driver's pocket or hanging from its hook in the home. When the car is locked, they can use the standard diagnostic port or computer hacker to program an unlocked key fob to gain control of the vehicle.
Automobile manufacturers have come up with a range of anti-theft systems to safeguard against these types of attacks. However, thieves will always come up with ways to thwart these measures.
For example, they've started using devices that transmit on the same frequency as remote key fobs in order to intercept their signals. The crooks can then copy the key fob's unlock code and then start the car using this fake signal.
This method is especially popular in the US where a lot of cars come with wireless technology. Owners can unlock and start their vehicle through a mobile application from their mobile. This technique is likely to increase in popularity as more car manufacturers attempt to connect their cars to their owners' smartphones.
It is essential that drivers follow the best practices when parking their vehicles. It is not advisable to leave the key fobs in ignition and lock the car when they are not in it. If possible it is also recommended to use a steering or gearstick locking device. They should get more info also consider installing a tracking device to their vehicle in the event that it gets stolen.
Flat Battery
This kind of attack is more prevalent than most people realize. The thieves employ inexpensive devices that extend the signal of your key fob in order to unlock and start your car even when it's off. Then, they drive the car to the trailer or around a corner and take the car away. It is possible to protect your car from this by installing an interrupter switch for the starter circuit. Simpler versions include an ON/OFF button which interrupts the circuit. It's priced at around $15 and is easy enough to put in yourself.
Car thieves are always looking for new ways to get into vehicles and then steal them. Car manufacturers, police and insurance companies are always trying to stay on top of the latest methods and offer more effective anti-theft systems for modern vehicles. But that doesn't stop thieves who are able adapt quickly and find ways to get around the most up-to-date anti-theft systems.
For instance, a lot of criminals employ a device that works on the same radio frequency as the fob to jam the signal. The device is tucked away in the pocket or near the vehicle and blocks the fob from transmitting the lock command to the car. This can be accomplished in just a few seconds. The device is cheap and readily available online.
Another tactic is to hack the car's computer system. This is more difficult but possible. Hackers have designed devices that plug into the diagnostic port of all vehicles and permit them to connect to the software. From there, they can program the blank key fob to start working. It is possible to do this on older vehicles too, but it's more difficult if you remove the ignition.
This method could be more popular if more vehicles are connected with drivers' mobile phones. Once a criminal has the username and password for an app for vehicles they are able to open the car or get it started with the app on their phone. You can guard yourself by not putting valuables inside your car, and also by parking in a garage.
