Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or at their door, they may unknowingly allow thieves to steal their signal. This relay attack is a high-tech method criminals use to steal new keyless vehicles.
Keyless ignition vehicles emit a low-power radio signal seeking a compatible fob that can respond. If the signal is captured and recreated, it could be used to unlock the car and then start it up.
Relay Attack
Imagine your car at your driveway, with your key fob in your home. You may think your vehicle is secure but sophisticated thieves are planning to steal your car without you knowing. Instead of breaking windows or jimmying locks, thieves are leveraging technology to gain access to cars through digital cracks in their armor. Known as relay theft, it's becoming a common method of stealing vehicles that have keyless entry.
Keyless entry cars are designed to operate via a signal transmitted from the remote control (RF) transmitter to the owner's key fob. To ensure that keyless entry is not unauthorized the RF transmitters on the key fob and in the car are programmed to only be activated when they're within a specific distance of each other. However, thieves are able to override this restriction using a technique called the 'relay attack'.
To do so, two people work together One stands near the car with a device that captures digitally the key fob's signal. The other person, 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 trick tricks the car into thinking that the key fob is close enough to allow it to unlock and begin the engine.
This type of heist used to require expensive equipment. However, now you can buy a relay transmitter on the cheap online and execute an heist in a matter of minutes. This is the reason car thieves love it.
While certain vehicles are less prone to this kind of theft than others, all modern vehicles with keyless entry are vulnerable. Researchers have tested 237 of the most popular cars and found that every one of them are susceptible to being stolen through this method.
Tesla vehicles are believed to be less susceptible to this type of theft, however the company hasn't yet implemented UWB features to effectively conduct distance checks on the car's signal and stop relay attacks. The company has said that they'll implement this in the near future, but until then, they are vulnerable. That's why it's essential to adopt a proactive approach to your vehicle security and install an anti-theft tool that protects your keys and car from these types of attacks.
CAN Injection Attack
Modern cars are designed to guard themselves from theft by exchanging cryptographic messages with the key to prove it's genuine. The system is thought to be secure, but thieves have found ways to get around it. They fake the identity of the smart key, then send messages to the vehicle, and then drive off. To do that they gain access to the smart key's internal communications network.
Most cars today are equipped with between 20 and over 200 electronic control units, also known as ECUs, that control different aspects of the vehicle's operation. They communicate using an electronic network known as CAN bus. To keep power consumption low the ECUs go into a low-power sleep mode that's activated when they receive a wake up frame. These frames typically come via the door or smart key receiver ECU. However, these messages aren't always encrypted or authenticated, which means that they could be snatched by criminals using a cheap and simple device.
To do this, they look for a place where they can 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 get them, you need to remove the bumper and cut holes in the headlamp assemblies. The thieves then use a device called an CAN injection attacker, which is used to send fake messages which trick the car's security systems to unlock it and disable its engine immobilizer.
The devices are available on 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. Researchers who have discovered the CAN Injection attack recommend that all car manufacturers fix this in their existing models. However, these thieves will continue taking everything they can. We can stop this from happening by installing mechanical security measures, such as Discloks inside all of our cars and parking them in well-lit, well-lit areas.
Blocking the Signal
In a variant of the relay attack, which makes use of a device that is able to block the signal sent by key fobs while the vehicle is locked. The device could be hidden in the pocket or hiding the location of a thief in a parking lot, or in the driveway being targeted. Once owners hit the button to lock their fobs and walk away and leave, they don't have to think about whether or not their car is really is locked. Instead, thieves could escape with the vehicle because the signal that normally locks the car has been blocked by the device of the criminal.
They also make use of devices that amplify signals from the key fob to unlock vehicles. They can do this while the key is in the driver's pocket or hanging from its hook in the home. After the car is locked, hackers can use an ordinary diagnosis port to program an unlocked fob.
Automobile manufacturers have developed various anti-theft devices to guard against these kinds of attacks. However, criminals are constantly finding ways to beat these measures.
For instance, they've been using devices that transmit on the same frequency as remote key fobs to intercept their signals. The thieves copy the unlock code of the key fob and start the vehicle using this fake signal.
This method is especially popular in the US where a lot of cars have wireless technology. Owners can unlock and start their vehicle by using a mobile app on their phone. This technology is likely 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 important for drivers to leverage best practices when they park their cars. They should not leave the keys in ignition and should always secure the car when they are not in it. If possible, they should also use a gearstick lock or steering device. It is also recommended to think about installing a tracking device on their vehicle in the event it is stolen.
Flat Battery
This kind of attack is more common than people think. Thieves employ inexpensive devices to extend the signal from your website key fob to unlock and start the car, even if it's shut 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 an interrupter switch for the starter circuit. Simpler versions include an ON/OFF button which interrupts the circuit. It's about $15 and is simple to install.
Car thieves are always looking for new ways to take vehicles. Car manufacturers, police and insurance companies are always trying to stay abreast of the latest techniques and offer better anti theft systems for modern vehicles. However, that doesn't stop thieves, who are able to be quick to adapt and find ways to get around the most recent anti-theft measures.
For instance, a lot of thieves use a device that works on the same radio frequency as the fob in order to block the signal. They put the device in their pocket or near their vehicle, and it stops the fob's lock commands from reaching the car and thereby leaving it unlocked. This can be accomplished in a matter of minutes. The device is affordable and easily accessible online.
Another tactic is to hack the car's computer system. This is more difficult but still possible. Every car has an diagnostic port and hackers have developed devices that plug into them and allow them access the software of the car. From there, they are able to program a blank key fob and get it to work. It is possible to do this on older vehicles as well, but it's more difficult without removing the ignition.
This method is likely to be more popular if more vehicles are connected with drivers' phones. Once a criminal has the username and password to an app for vehicles, they can then unlock or start the car with the app on their phone. You can protect yourself by not leaving valuables inside your car, and by parking in garages.
