Cars Being Stolen With Keyless Entry
Car owners who throw their keys on tables or in front of their front door could be allowing thieves to hijack the signal. This relay attack is one of the advanced methods criminals are employing to steal new keyless cars.
Keyless ignition cars emit a low-power radio signal seeking a compatible fob to respond. If the signal is recorded and recreated, it can be used unlock the car and start it.
Relay Attack
Imagine your car being parked safely in the driveway, and the key fob safely inside your home. You're sure that your car is safe, but unnoticed by you, sophisticated thieves are plotting an attack. Instead of slamming windows and jiggling locks, these thieves are using technology to hack into cars via digital cracks in their armor. This is known as relay theft, it's a more common method of stealing vehicles with keyless entry.
Keyless entry cars are designed to operate using a signal that is transmitted from the car's remote control (RF) transmitter to the owner's key fob. To ensure that keyless entry is not accessed by intruders the RF transmitters that are on the key fob as well as the car are programmed only to turn on when they are within a specific distance of each other. However, thieves can overcome this limitation using a technique known as the'relay attack'.
To do so, two people work together One stands near the car with an instrument that records a digitized version of the key fob's signal. The other, standing by the house of the owner is using a different device to transmit the key fob signal back to the car. This trickery fools the car into believing that the key fob has traveled a distance sufficient to allow it to be opened and started the vehicle.
This kind of heist used to require expensive equipment. Now, you can purchase relay transmitters for cheap online and execute the heist in just a few minutes. This is the reason car thieves love it.
While some cars are less prone to this type 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 could be taken through this method.
Tesla cars are said to be less prone to this kind of theft, but Tesla hasn't yet implemented UWB features that could effectively check distances on the car's signal and stop relay attacks. The company has promised to do so in the future, but for now, they remain vulnerable. Installing an anti-theft system that guards your car and your keys against such attacks is a proactive way to ensure the security of your vehicle.
CAN Injection Attack
Modern cars can guard themselves from thieves by exchanging encrypted messages with the key to confirm its authenticity. The system is believed to be secure, but thieves have found ways to get around it. They can pretend to be the smart key and send other messages to the car, letting it unlock the doors, disable its engine immobilizer, then let them leave the car. To do that, they get access to the smart key's internal communication network.
Nowadays, the majority of cars are equipped with between 20 to 200 electronic control units (or ECUs) which control different aspects of the car's operation. They communicate with each other using an electronic network referred to as CAN bus. To reduce power consumption the ECUs go into the sleep mode at low power. This mode is activated when they receive a wake up' frame. These frames are typically sent from the door or smart key receiver ECU. However, these messages aren't always encrypted or authenticated and, therefore, can be intercepted by criminals with a cheap and simple device.
They search for a spot where they can connect directly to the CAN connection wires. These are often hidden away inside the headlights or elsewhere in the front of the car, and are accessible by pulling the bumper and cutting holes in the headlamp assembly to expose the wires. The criminals then employ a device known as 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 purchased 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 discovered the CAN Injection attack recommend that all car makers address this issue in their existing models. However, these thieves will continue to take everything they can. We can prevent this by implementing mechanical safety measures, such as Discloks inside all our vehicles and parking them in well-lit and visible areas.
Blocking the Signal
In a different variation of the relay attack, thieves may make use of a device to block the signal that is sent by a key fob when the vehicle is locked. The device could be found hidden in the pocket of a burglar in a parking area or in a hidden spot close to the driveway that is being targeted. Once owners hit the lock button on their fobs, and then walk away they don't consider whether or not their car is actually locks. Instead, thieves are able to escape with the vehicle since the signal that normally locks the car is blocked by the crook's device.
The crooks also make use of devices to enhance the signal of the key fob to unlock vehicles. They can accomplish this if the key is inside the pocket of the driver or hanging from a hook inside the house. Once the car is unlocked, they can make use of an ordinary diagnostic port or computer hacker to program an unlocked key fob to gain control over the vehicle.
Automobile manufacturers have developed a range of anti-theft systems to safeguard against these types of attacks. But, thieves are constantly finding ways to beat these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The crooks can then copy the key fob's unlock code and then start the car with this fake signal.
This method is particularly popular in the US, where many cars come with wireless technology. Owners can unlock and start their vehicle using a mobile application more info on their phone. This technology will likely be more commonplace as more companies attempt to link their cars with their owners phones.
In addition to incorporating anti-theft technology in vehicles, it's vital for drivers to leverage best practices when they park their vehicles. They shouldn't leave their key fobs in the ignition, and should always make sure the car is securely locked when they're not there and should make use of an engine or steering wheel lock, if it is possible. It is also recommended to think about installing a tracking device onto their vehicle in case it is stolen.
Flat Battery
This type of attack is more common than many people believe. The thieves make use of cheap devices that extend the signal of your key fob to unlock and start your car when it's off. They then drive the car around a corner or to a trailer and then drive off with it. It would be possible to shield your vehicle from this by installing an interrupter switch for the starter circuit. Simpler versions have an ON/OFF button that shuts off the circuit. It is priced at around $15 and is simple to install.
Car thieves are constantly searching for new ways to take vehicles. Car manufacturers, police and insurance companies are constantly trying to stay abreast of the latest tactics and provide better anti-theft systems for modern vehicles. But this does not stop thieves who are able to be quick to adapt and find ways around the latest anti-theft technology.
For instance, a lot of thieves use a device that works on the same radio frequency as the fob to jam the signal. The device is placed in the pocket or close to the vehicle and blocks the fob from sending the lock command to the car. This can be done in just a few seconds. The device is cheap and can be purchased online.
Hacking the computer system of the car is an alternative option. This is more difficult but it is still feasible. Every car has an diagnostic port and hackers have designed devices that connect to them and let them access the car's software. From there, they can program an unfinished key fob and get it to work. This is also possible on older vehicles, however it is more difficult to do so without removal of the ignition lock.
As more vehicles are connected to drivers' phones the method is likely to be more popular. Once a thief gets the username and password to an app for vehicles they are able to open the car or get it started by using the app on their phone. You can safeguard yourself by not putting valuables inside your car, and by parking in a garage.
