Cars Being Stolen With Keyless Entry
Car owners who throw keys on tables or near their front door could be permitting thieves to steal the signal. This relay attack is a highly-tech method criminals use to steal new keyless vehicles.
Keyless ignition cars emit a low-power radio signal looking for a matching fob to respond. If the signal is captured and recreated, it can be used to unlock the car and to start it.
Relay Attack
Imagine your car safely at your driveway, with your key fob inside your home. You're confident that your vehicle is safe, but unnoticed by you, sophisticated thieves are plotting an heist. Instead of breaking windows or jimmying locks, they are leveraging technology to hack into cars via digital cracks in their armor. This method of stealing cars with keyless access is known as relay theft.
Cars with keyless entry are designed to function using signals that are sent from the car's remote control (RF) transmitter to the owner's key fob. To stop keyless entry by intruders the RF transmitters on the key fob as well as the car are programmed only to activate when they are within a specified distance from one another. However, thieves can bypass this limitation with 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 digitally the the key fob. The other, in the vicinity of the home of the owner and using a second device to transmit the key fob signal back down to the car. This trickery fools the car into thinking the key fob is near enough to be able to unlock it and start the engine.
In the past, this type of attack required expensive equipment in order to execute. Today, you can purchase a relay transmitter for a small price on the internet and complete an heist in just a few minutes. This is why car thieves love it.
All modern vehicles with keyless access are at risk. Certain vehicles are more vulnerable to this type than others. In fact, researchers have tested 237 popular cars and found that they can be all stolen using this method.
Tesla vehicles are supposedly less prone to this kind of theft, however Tesla hasn't yet implemented UWB features that would effectively perform distance checks on the car's signal and protect against relay attacks. The company has stated that they will implement this in the near future, however until then they are vulnerable. That's why it's essential to adopt a proactive approach to your security in your car and install an anti-theft kit that protects your keys and car from these types of attacks.
CAN Injection Attack
Modern cars can protect themselves from thieves by sending encrypted messages to the key in order to prove its authenticity. This method is generally thought to be secure, but criminals have found a way around it. They can impersonate the smart key, and send messages to the car letting it unlock the doors, turn off its engine immobilizer, and then go on their way. To do this they have access to the smart key's internal communication network.
Most cars today are equipped with between 20 and 200 electronic control units, or ECUs, that control different aspects of the vehicle's operation. They communicate via a network called CAN bus. To keep power consumption low, these ECUs go into sleep mode with low power that is activated when they receive a wake up' frame. These frames are usually sent by the ECU that controls the smart key or door. However the messages aren't usually authenticated or encrypted so they can be intercepted by criminals with a cheap and basic device.
They search for a spot where they can connect directly to the wires of the CAN connection. These are often hidden away in the headlights or in the front of the car, and can be accessed by removing the bumper and cutting holes in the headlamp assembly to expose them. The thieves employ an instrument known as a CAN injection attack to send fake messages that trick the car's safety systems to unlock and disable the engine immobilizer.
These devices can be bought 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. The researchers who discovered this CAN Injection attack are recommending that all car manufacturers fix the issue in their current models, but the reality is that thieves will continue to take anything they can get their hands on. We can stop this by installing mechanical safety measures, such as Discloks inside all of our cars and parking them in well-lit and visible areas.
Blocking the Signal
In a variation of the relay attack, which makes use of a device that can be used to block the signal transmitted by a key fob while the vehicle is locked. The device may be inside the pocket of a burglar in a parking area or in a hiding spot close to the driveway that is being targeted. Once the owners press the lock button on their fobs and leave they don't consider whether or not the car is actually locks. Instead, thieves are able to escape with the vehicle because the signal that normally locks the car is blocked by the device of the criminal.
They also use devices that amplify signals from the key fob to unlock vehicles. They can even do this when the key is in the pocket of the driver or hanging from its hook inside the house. Once the car has been locked, hackers can use an ordinary diagnosis port to create a blank fob.
Car manufacturers have developed various anti-theft devices to guard against these kinds of attacks. But thieves always come up with new ways to beat these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs to intercept signals. The thieves can then copy the key fob's unlock code and then start the car with 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 smartphone. This technology is likely to gain popularity as more and more manufacturers attempt to link their vehicles to owners' smartphones.
In addition to installing anti-theft technologies in vehicles, it's vital for drivers to follow the best practices when they park their cars. It is not advisable to leave the keys in ignition and should always lock the car when not in it. If possible, they should also use a steering or gearstick locking device. It is also recommended to consider having a tracking device fitted to their car in the event it is stolen.
Flat Battery
This type of attack is more frequent than people think. The thieves make use of inexpensive devices that extend the signal from your key fob to unlock and start your car, even in the event that it is click here off. They then simply drive the car around a corner or onto a trailer to then drive off with it. It would be possible to shield your vehicle from this by installing an interrupter for the starter circuit. Simpler versions come with an ON/OFF button which interrupts the circuit. It's about $15 and is easy to install.
Car thieves are constantly searching for new ways to rob vehicles. Police, car manufacturers and insurance companies are always trying to keep up with the latest methods and offer more effective anti-theft systems for modern vehicles. But this isn't stopping thieves who adapt quickly and find ways around the most recent anti-theft measures.
Many thieves block the signal using a device that uses the same radio frequency of the fob. The device is tucked away in the pocket or close to the vehicle and blocks the fob from sending the lock command to the car. This can be accomplished in a matter of minutes. The device is inexpensive and easily accessible on the internet.
Another option is to hack into the car's computer system. This is more difficult, but possible. All cars have an diagnostic port, and hackers have developed devices that plug into them and let them access the car's software. They can then program a blank fob to work. It is possible to do this on older cars as well but it's more difficult without taking out the ignition.
As more vehicles are connected to drivers' phones, this method may be more popular. Once a burglar has gained the username and password for an app for vehicles and then they can unlock the car or start it with the app on their phone. It is possible to be safe from these kinds of attacks by not leaving valuables in your car and parking it in a garage or secured parking lot.
