Cars Being Stolen With Keyless Entry
Car owners who toss their keys on tables or near their front door could be permitting thieves to steal the signal. This relay attack is one of the high-tech methods criminals are using to steal new keys from cars.
Keyless ignition vehicles emit a low-power radio signal seeking a compatible fob to 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 safely parked in your driveway, with the key fob safely in your home. You may think your car is safe, but sophisticated thieves are planning to steal your car without you being aware. Instead of slamming windows and jiggling locks, these thieves are leveraging technology to hack into cars via digital chinks in their armor. This method of stealing cars with keyless access is called relay theft.
The keyless entry system in cars is controlled by a signal from the car's RF transmitter to the key fob. To ensure that keyless entry is not accessed by intruders, the RF transmitters on the key fob as well as the car are programmed to activate when they are within a certain distance from one another. However, thieves are able to overcome this limitation using an attack known as the'relay attack'.
Two individuals are required to perform this: one person stands near the car and uses a device that captures an electronic version of the signal coming from the key fob. The other, in the vicinity of the house of the owner is using a different device to send the key fob signal back to the car. This trick tricks the car into thinking the key fob is close enough to be able to unlock it and start the engine.
In the past, this type of attack required expensive equipment to carry out. But now, you can pick up a relay transmitter on the cheap online and execute the heist in just a few minutes. This is why car thieves are enthralled by it.
While some cars are less vulnerable to this kind of theft than others, all modern cars with keyless entry are vulnerable. In fact, researchers have tested 237 popular cars and found that they could be all stolen using this method.
Tesla vehicles are believed to be less susceptible to this type of theft, however, Tesla hasn't yet implemented UWB features that could effectively check distances on the car's signal to protect against relay attacks. The company has stated that they will implement this feature in the near future, but for now they are still vulnerable. That's why it's essential to be proactive about your car security and install an anti-theft kit that safeguards your keys and vehicle from these kinds of attacks.
CAN Injection Attack
Modern cars can protect themselves from theft by exchanging encrypted messages with the key to prove its authenticity. This method is generally thought to be secure, but criminals have found a way to circumvent it. They simply impersonate the smart key and send other messages to the car, letting it unlock the doors, turn off its engine immobilizer, and let them go on their way. To do that they gain access to the smart key's internal communications network.
Today, most automobiles are equipped with between 20 to 200 electronic control units (or ECUs) that control various aspects of the car's operation. They communicate with each other using an electronic network referred to 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 usually sent by the ECU that is in charge of the smart key or door. However the messages aren't usually authenticated or encrypted, which means that they can be intercepted by criminals using a cheap and simple device.
They look for a place where they can connect directly to the wires for CAN connection. They are usually hidden within the headlights or here in front of the vehicle, and can be accessed by removing the bumper and cutting holes in the headlamp assembly to expose the wires. The thieves then employ a device known as 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 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 thieves will continue to take anything they can get their hands on. The best we can do is to attempt to stop this from happening by installing security measures that are mechanical such as Discloks on all of our vehicles and ensuring that they're always located in areas with adequate lighting that are clearly visible to passers-by.
Blocking the Signal
In a variation of the relay attack, which employs a device that can be used to block the signal sent by a key fob while the vehicle is locked. The device could be found in the pocket or in the hiding the location of a thief in the parking lot, or near the driveway that is being targeted. Owners aren't able to verify if the vehicle is locked after pressing the lock button. Instead, thieves are able to escape with the vehicle since the signal that normally locks the car has been blocked by the device of the criminal.
The crooks also make use of devices to amplify the signal from the key fob in order to unlock vehicles. They can accomplish this if the key is in the driver's pocket or hanging from its hook in the home. After the car has been unlocked, they can make use of the standard diagnostic port or computer hackers to program an unlocked key fob to gain control of the vehicle.
Car manufacturers have come up with a variety of anti-theft solutions to safeguard against these types of attacks. 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 of the key fob and then start the car with this fake signal.
This method is especially popular in the US, where many cars have wireless technology. Owners can unlock and start their vehicle through a mobile application on their smartphone. This technology is likely to increase in popularity as more car manufacturers attempt to link their cars with their owners phones.
In addition to incorporating anti-theft technology in vehicles, it's important for drivers to use the best practices when they park their cars. They shouldn't leave their key fobs in the ignition, should always ensure that the vehicle is locked completely when they're not there and should use an engine or steering wheel lock, if it is possible. It is also recommended to consider having a tracking device fitted to their car in case it's stolen.
Flat Battery
This type of attack occurs more often than we think. Thieves make use of cheap devices to extend the signal from your key fob to open and start the car, even if it's turned off. They then drive the car around the corner or to a trailer and then drive off with it. Installing an interruption switch to the starter circuit would protect your car against this. The most basic ones have an ON/OFF switch that interrupts the starter circuit. It's about $15 and is simple to install.
Car thieves are always trying new ways to gain access to vehicles and steal them. Police, car manufacturers and insurance companies are always trying to stay abreast of the latest tactics and provide better anti-theft systems for modern vehicles. But this does not stop thieves who are able to be quick to adapt and find ways to circumvent the latest anti theft measures.
For instance, a lot of criminals use a device that works on the same radio frequency as the fob to jam the signal. 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 accomplished in a matter of minutes. The device is inexpensive and can be purchased on the internet.
Hacking the computer system of the car is an alternative option. This is harder but still feasible. Hackers have developed devices that connect to the diagnostic port of all vehicles and allow them to access the software. They can then program a blank fob to function. This can also be done on older cars, although it is more difficult to do so without removal of the ignition lock.
As more vehicles are linked to the phones of drivers and this method could become more popular as well. Once a burglar has gained the username and password for the vehicle app, they can then unlock or start the car by using the app on their phone. You can help be safe from these kinds of attacks by not leaving valuables in your car and parking it in a garage or secure parking lot.
