Cars Being Stolen With Keyless Entry
Car owners who throw keys on tables or near their front doors may be unwittingly giving thieves the ability to take over the signal. This relay attack is one of the high-tech methods criminals are using to steal brand new keyless cars.
Keyless ignition vehicles emit a low-power radio signal looking for a matching fob to respond. If the signal is recorded and recreated, it could be used to unlock the car and start it.
Relay Attack
Imagine your car safely at your driveway, with your key fob at home. You may be confident that your car is safe but sophisticated thieves are planning a heist, without you even knowing. These thieves use technology to snoop on vehicles through digital chinks. Also known as relay theft, it's an increasingly popular method of stealing cars with keyless entry.
Cars with keyless entry are designed to operate via signals that are that is transmitted from the remote control (RF) transmitter to the owner's key fob. To prevent unauthorized keyless entry the RF transmitters on the key fob as well as in the car are programmed to only be activated when they're within certain distance from each other. However, thieves are able to override this restriction using an attack known as the'relay attack'.
To do so, two people work in tandem: one stands by the car with the device that captures a digitized version of the key fob's signal. The other person, who is at home with 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 near enough to unlock and start the engine.
This type of heist was once a costly process that required expensive equipment. Now, you can pick up relay transmitters on the cheap online and execute the heist in just a few minutes. This is why it's so popular with car thieves.
While certain vehicles are less vulnerable to this type of theft than others, all modern cars with keyless entry are at risk. In fact researchers have tested 237 popular vehicles and found that they could be targeted by this method.
Tesla vehicles are believed to be less prone to this kind of theft, however the company hasn't yet implemented UWB features that would effectively conduct distance checks on the car's signal and stop relay attacks. The company has stated that they will do so in the future, but until then they are still vulnerable. Installing an anti-theft system that protects both your car keys and your keys against these types of attacks is a proactive method to ensure the security of your vehicle.
CAN Injection Attack
Modern cars can protect themselves from thieves by transferring encrypted messages using the key in order to prove its authenticity. This method is generally thought to be secure, but thieves have found a way around it. They can impersonate the smart key, and send other messages to the car letting it unlock the doors, disable its engine immobilizer, and then leave the car. To do this, they get access to the smart key's internal communication network.
These days, most automobiles are equipped with between 20 and 200 electronic control units (or ECUs) that manage different aspects of the car's operation. They communicate via the CAN bus network. To ensure that power consumption is low, these ECUs enter a low-power sleep mode that's activated when they receive a 'wake up' frame. These frames typically come through the door or a smart key receiver ECU. These messages are not always authenticated or encrypted. This means that criminals are able to intercept them with a simple and cheap device.
They look for a place where they can connect directly to the wires for CAN connection. These are often hidden away in the headlights or in front of the vehicle, and can be accessed by pulling the bumper off and cutting holes in the headlamp assembly to expose them. The criminals then employ a device known as an CAN injection attacker, which is used to send out fake messages that trick the car's security systems into unlocking it and disengaging its engine immobilizer.
These devices are available for purchase on the Dark Web, and work for all major car manufacturers including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and many more. Researchers who have discovered the CAN Injection attack recommend that all car manufacturers fix this issue in their existing models. However, these criminals will continue to take everything they can. The best we can do is attempt to stop this from happening by putting in mechanical security measures like Discloks on cars, and making sure that they are located in areas with adequate lighting that are clearly visible to passers-by.
The Signal is blocked
In a variation of the relay attack that uses a gadget that can be used to block the signal from key fobs while the vehicle is locked. The device could be in the pocket of a burglar in a parking lot or in a hidden spot near the driveway being targeted. Once owners hit the lock button on their fobs and leave they don't consider whether or not the car is really is locked. Instead, thieves could take off with the car because the signal that normally locks the car has been blocked by the crook's device.
They also have devices that amplify signals from the key fob to unlock vehicles. They may even do this when the key is inside the pocket of the driver or hanging from a hook inside the house. After the car has been unlocked, they can use an ordinary diagnostic port or computer hackers to program an unlocked key fob to gain control over the vehicle.
Car manufacturers have developed a range of anti-theft systems to safeguard against these types of attacks. But thieves always find ways to defeat these measures.
For example, they've started using devices that transmit on the same radio frequency as remote key fobs to intercept their signals. The thieves can then copy the unlock code of the key fob and start the car with this fake signal.
This technique is particularly popular in the US where a lot of cars have wireless technology. Owners can start and unlock their car get more info using a mobile application from their mobile. This technology will likely become more popular as more manufacturers try to connect their vehicles with their owners smartphones.
In addition to installing anti-theft technologies in vehicles, it's vital for drivers to leverage best practices when parking their vehicles. They shouldn't leave their keys in the ignition, and should always make sure the car is securely locked when they're not using it and should utilize an engine or steering wheel lock, if they can. It is also recommended to think about installing a tracking device onto their vehicle in the event that it's stolen.
Flat Battery
This type of attack is more frequent than most people realize. 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. Then they drive the car to a trailer or around a corner and take the vehicle away. Installing an interrupter switch for the starter circuit would protect your car against this. Simpler versions have an ON/OFF button that shuts off the circuit. It costs around $15 and is simple to install.
Car thieves are constantly looking for new ways to steal vehicles. The police as well as the car makers and insurance companies are constantly trying to catch up with their strategies and provide better anti-theft systems for modern cars. However, this doesn't stop thieves who can be quick to adapt and find ways to circumvent the latest anti-theft technology.
Many thieves jam the signal with devices that use the same radio frequency as the fob. They put the device in their pocket or in a location near their vehicle, and it prevents the fob's lock commands from reaching the vehicle, leaving the vehicle unlocked. This can be done in just a few seconds. The device is affordable and can be purchased online.
Another strategy is to hack the car's computer system. This is harder but still feasible. Hackers have developed devices that plug into the diagnostic port of all cars and allow them to connect to the software. From there, they are able to program an unfinished key fob and start working. It is possible to do this with older cars also however it is more difficult without removing the ignition.
As more vehicles are linked to drivers' phones the method is likely to become more popular too. Once a thief has access to the username and password to a vehicle application, they can unlock or start the vehicle by using the application. You can guard yourself by not leaving valuables in your car and parking in garages.
