Cars Being Stolen With Keyless Entry
Car owners who toss their keys on tables or near their front door may be unwittingly allowing thieves to hijack the signal. This relay attack is just one of the advanced methods criminals are using to steal brand new keyless cars.
All keyless ignition cars emit an extremely low-power radio signal, looking for a matching fob that can respond. If the signal is captured and recreated, it could be used to unlock the car and start it up.
Relay Attack
Picture your car parked securely in the driveway, and the key fob tucked away inside your home. You're confident that your vehicle is safe, but unnoticed by you sophisticated thieves are planning an heist. Instead of slamming windows or jiggling locks, these thieves are leveraging technology to hack into cars via digital chinks in their armor. Known as relay theft, it's a more common method of stealing vehicles with keyless entry.
The keyless entry system in cars is controlled by a signal sent by the car's radio transmitter to the key fob. To stop keyless entry by unauthorized individuals, the RF transmitters on the key fob as well as the car are programmed to activate when they are within a specified distance of each other. The thief can bypass this restriction by employing a method known as the relay-attack.
To do so, two people work together one is positioned by the car with the device that captures digitally the key fob's signal. The other, in the vicinity of the home of the owner, uses a second device to send the key fob's signal to the car. This trick tricked the car into thinking the key fob is close enough to allow it to unlock and begin the engine.
In the past, this kind of heist required expensive equipment to carry out. You can now buy a relay transmitter for a small price on the internet and complete an heist in just a few minutes. This is the reason it's popular among car thieves.
All modern cars with keyless access are vulnerable. Certain cars are more susceptible to this kind of attack than others. In fact researchers have examined 237 popular vehicles and found that they could all be stolen using this method.
Tesla vehicles are believed to be less vulnerable to this type of theft, however Tesla 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 future but until then, they are vulnerable. Installing an anti-theft device that protects both your car and your keys against such a threat is a proactive way to ensure your car's security.
CAN Injection Attack
Modern vehicles are designed to shield themselves from thieves by transferring cryptographic messages using the key to prove that it's genuine. This system is generally reckoned to be secure, but criminals have found a way around it. They pretend to be a smart key, send messages to the vehicle, and then drive off. To accomplish this, they have access to the smart keys' internal communication network.
Today, most cars 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 with each other using an electronic network referred to as CAN bus. To ensure that power consumption is low they ECUs enter a low-power sleep mode that's activated when they receive a 'wake up frame. These frames are typically sent through the door or a smart key receiver ECU. These messages aren't always authenticated or encrypted. This means that criminals can take them over with the use of a cheap and simple device.
They search for a location that allows them to connect directly to the wires for CAN connection. They are usually hidden in the headlights or in the front of the vehicle, and are accessible by pulling the bumper off and cutting holes in the headlamp assembly to expose them. The thieves then employ a device dubbed an CAN injection attacker to send fake messages that trick the car's security systems into unlocking it and disengaging its engine immobilizer.
These devices can be bought on the Dark Web and work with most major car manufacturers which include 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, the thieves will continue to steal everything they can. We can prevent this by implementing mechanical safety measures such as Discloks in every car we own and parking them in well-lit, visible areas.
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 car is locked. The device could be in the pocket or hiding the location of a thief in an open parking lot or even near the driveway being targeted. When owners press the lock button on their fobs and leave they don't consider whether or not their car is actually locks. Instead, thieves are able to escape with the vehicle because the signal that normally locks the car has been blocked by the crook's device.
They also make use of devices that amplify signals from the key fob to unlock vehicles. The crooks check here can do this even when the key is in a driver's pocket or hanging on a hook inside the home. After the car is unlocked, hackers can make use of the standard diagnostic port to program an unlocked fob.
Automobile manufacturers have come up with a variety of anti-theft solutions to protect against these types of attacks. However, thieves are always trying to beat these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs to intercept signals. The thieves copy the unlock code of the key fob and begin the vehicle using this fake signal.
This technique is particularly popular in the US where a lot of cars come with wireless technology. Owners can start and unlock their car through a mobile application on their phone. This technology is expected to become more popular as more and more car manufacturers attempt to connect their vehicles with their owner's smartphones.
It is crucial that drivers follow the best practices when parking their vehicles. They should never leave their keys in the ignition, should always make sure the vehicle is locked completely when they're not using it and should utilize a steering wheel or gearstick lock if possible. It is also recommended to think about installing a tracking device on their vehicle in the event that it's stolen.
Flat Battery
This kind of attack happens more often than people realize. Thieves employ cheap devices to extend the signal from your key fob to unlock and begin cars even if they're switched off. Then, they drive the car to a trailer or around a corner and take the vehicle away. It is possible to shield your vehicle from this by installing an interrupter for the starter circuit. Simpler versions come with an ON/OFF button that interrupts the circuit. It's about $15 and is simple to install.
Car thieves are always searching for new ways to rob vehicles. Car manufacturers, police and insurance companies are constantly trying to stay on top of the latest tactics and provide 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 circumvent the most recent anti-theft measures.
Many thieves jam the signal with a device that uses the same radio frequency of the fob. They put the device in their pockets or in a location close to their vehicle, and it prevents the fob's lock command from reaching the vehicle, leaving the vehicle unlocked. This can be accomplished in a matter of seconds. The device is cheap and readily available on the internet.
Another option is to hack into the car's computer system. This is more difficult, but nevertheless feasible. All cars have an diagnostic port, and hackers have created devices that plug into them and let them access the software of the car. From there, they can program an unfinished key fob and get it to work. It is possible to do this with older cars too however it is more difficult without taking out the ignition.
As more vehicles are linked to drivers' phones, this method may become more popular as well. Once a criminal has the username and password to an app for vehicles and then they can open the car or get it started by using the app on their phone. You can guard yourself by not leaving valuables in your car and also by parking in garages.
