Cars Being Stolen With Keyless Entry
Car owners who throw their keys on tables or near their front doors could be allowing thieves to hijack the signal. This relay attack is one of the latest techniques criminals are using 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 recorded and recreated, it could be used to unlock the car and start it up.
Relay Attack
Imagine your car safely parked in the driveway, and the key fob sitting safely inside your home. You're confident that your car is secure, but unseen by you sophisticated thieves are planning an attack. They use technology to hack into vehicles using digital chinks. This method of stealing cars with keys is known as relay theft.
The keyless entry system found in cars is controlled by a signal sent by the car's radio transmitter to the key fob. To prevent unauthorized keyless entry, the RF transmitters in the key fob as well as in the car are programmed to activate only when they're within a specific distance of each other. However, a thief can overcome this limitation using a technique called the 'relay attack'.
To accomplish this two people work in tandem One stands near the car, using a device that captures digitally the key fob's signal. The other, in the vicinity of the house of the owner, uses a second device to send the key fob's signal to the car. This trick tricks the car into thinking that the key fob is close enough to be able to unlock it and start it up.
This kind of heist used to require expensive equipment. Today, you can purchase an inexpensive relay transmitter online and carry out an heist in a matter of minutes. This is the reason it's popular with car thieves.
While certain cars are less susceptible to this kind of theft than others, all modern cars that have keyless entry are at risk. In fact researchers have tested 237 vehicles that are popular and found that they can all be stolen using this method.
Tesla vehicles are said to be less vulnerable to this kind of theft. However, the company hasn't yet implemented UWB technologies that would allow it to perform distance checks and stop attacks via relay. The company has said that they will do this in the near future, however until then they are vulnerable. Installing an anti-theft system that safeguards your car and your keys against such a threat is a proactive approach to ensure your car's security.
CAN Injection Attack
Modern vehicles can defend themselves from thieves by sending encrypted messages to the key in order to prove its authenticity. This system is generally reckoned to be secure, however thieves have found a way to circumvent it. They impersonate a smart key, transmit messages to the vehicle and then drive away. To do this they have access to the smart key's internal communication network.
The majority of cars today are fitted with between 20 and over 200 electronic control units, or ECUs, that manage various aspects of the vehicle's operation. They communicate with each other via the CAN bus. To ensure that power consumption is low the ECUs are put into sleep mode with low power that is activated when they receive a 'wake up' frame. These frames typically come through the door or a smart key receiver ECU. However, these messages aren't always encrypted or authenticated, which means that they can be intercepted by criminals using a cheap and basic device.
They search for a location that allows them to connect directly to the wires of the CAN connection. They are usually hidden in the headlights or in the front of the car, and can be accessed by pulling 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, which is used to send fake messages that can trick the car's security systems into unlocking the car and disengaging its engine immobilizer.
These devices can be bought through 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 the thieves will continue to grab whatever they can get their hands on. The best we can do is to try and prevent this by installing mechanical security measures like Discloks on all cars and ensuring that they are always placed in areas that are well-lit and are easily visible to pedestrians.
The Signal is blocked
In a variation of the relay attack that makes use of a device, thieves can jam the signal sent by the key fob when the car is locked. The device could be in the pocket of a thief in a parking lot or in a hiding spot close to the driveway that is being targeted. When owners press the button to lock their fobs and leave they don't consider whether or not the car really is locked. The device of the crook interferes with the signal to lock the car. Therefore, thieves can drive away with the vehicle.
They also have devices that amplify signals from the key fob to unlock vehicles. They can even accomplish this if the key is in the pocket of the driver or hanging from a hook in the house. Once the car has been locked, hackers can use an ordinary diagnosis port to create an unlocked fob.
Automobile manufacturers have come up with a variety of anti-theft solutions to guard against these kinds of attacks. But thieves always find ways to defeat these measures.
They've been using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The crooks then copy the unlock code of the key fob and start the car with this fake signal.
This technique is especially popular in the US and Europe where a large number of vehicles are sold with wireless technology that lets owners unlock and start their cars by using a mobile application on their smartphone. This technology will likely can keyless car be stolen be more commonplace as more manufacturers try to connect their cars to their owners' smartphones.
It is important that drivers follow the right procedures when parking their vehicles. It is not a good idea to leave keys in the ignition. They should always ensure that the car is securely locked when they're not in it and should use an engine or steering wheel lock, if they can. They should also consider installing a tracking device to their vehicle in the event that it is stolen.
Flat Battery
This kind of attack occurs more often than people realize. The thieves employ inexpensive devices that extend the signal of your key fob to unlock and start your car even when it's off. Then they drive the car to the trailer or around a corner, and take the car away. It would be possible to shield your vehicle from this by installing an interrupter switch for the starter circuit. The simplest ones are an ON/OFF switch which interrupts the starter circuit. It costs around $15 and is simple to install.
Car thieves are always seeking new ways to take vehicles. 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. However, that doesn't stop thieves who are able be quick to adapt and find ways to circumvent the latest anti-theft measures.
For instance, many criminals use a device that works on the same radio frequency as the fob in order to block the signal. The device is tucked away in the pocket or close by the vehicle, and stops the fob from transmitting the lock command to the car. This can be accomplished in a matter of minutes. The device is affordable and available online.
Another strategy is to hack the car's computer system. This is more difficult but possible. Hackers have designed devices that connect to the diagnostic port of all vehicles and permit them to access the software. They can then program a blank fob to work. This is also possible on older vehicles, however it is more difficult to do so without removal of the ignition lock.
This method could become more popular as more vehicles are connected to drivers' mobile phones. Once a criminal has access to the username and password to an application for vehicles they can open or start the vehicle using the application. You can safeguard yourself by not putting valuables inside your car, and by parking in garages.
