Cars Being Stolen With Keyless Entry
Car owners who throw their keys on a table or near their front door could be giving thieves the ability to take over the signal. This relay attack is a sophisticated method used by criminals to steal new keyless vehicles.
All keyless ignition cars emit an low-power radio signal that is seeking a compatible fob that can respond. If the signal is captured and recreated, it could be used to unlock the car and then start it up.
Relay Attack
Imagine your car safely parked in the driveway, and the key fob safely inside your home. You're sure that your car is safe, but not seen by you sophisticated thieves are planning an heist. They use technology to snoop on vehicles through digital chinks. Known as relay theft, it's becoming a common method of stealing vehicles that have keyless entry.
Keyless entry cars are designed to function using signals that are sent from the car's remote control (RF) transmitter to the owner's key fob. To prevent unauthorized keyless entry the RF transmitters inside the key fob and car are programmed to activate only when they're within a certain distance from each other. However, a thief can overcome this limitation using a technique known as the'relay attack'.
To accomplish this two people work in tandem One stands near the car and uses a device that captures digitally the key fob's signal. The other, in the vicinity of the home of the owner is using a different device to send the key fob signal back down to the car. This trickery tricks the car into believing that the key fob has reached the distance needed to unlock and start the vehicle.
This type of attack was once a costly process that required expensive equipment. You can now buy a cheap relay transmitter online and pull off a heist within minutes. This is why it's so popular with car thieves.
While certain cars are less susceptible to this type of theft than others, all modern cars with keyless entry are vulnerable. Researchers have tested 237 of the most popular automobiles and found that all of them could be taken using this method.
Tesla vehicles are supposedly less susceptible to this type of theft, however, the company has not yet implemented UWB features that would effectively perform distance checks on the car's signal to protect against relay attacks. The company has stated that they'll implement this in the near future, however until then, they're vulnerable. This is why it's crucial to be proactive about your security in your car and install an anti-theft device that safeguards your keys and the car from such attacks.
CAN Injection Attack
Modern cars can protect themselves from thieves by exchanging encrypted messages with the key in order to confirm its authenticity. This method is generally thought to be secure, however criminals have found a way around it. They impersonate a smart key, send messages to the vehicle, and then drive away. To achieve this, they need access to the smart keys' internal communication network.
The majority of cars today are fitted with between 20 and over 200 electronic control units, also known as ECUs, which control various aspects of the vehicle's operation. They communicate with each other via a network known as CAN bus. These ECUs enter a low-power sleep mode to reduce their power consumption. This mode is activated when the ECUs receive a "wake up" frame. These frames are usually sent by the ECU that is in charge of the smart key or door. These messages aren't always authenticated or encrypted. This means that thieves can take them over with an inexpensive and simple device.
They search for a location where they can connect directly to the wires of the CAN connection. They are usually hidden in the headlights or in other places in the front of the vehicle. To access them, you can remove the bumper and cut holes in the headlamp assemblies. The thieves then employ a device dubbed an CAN injection attacker, which is used to send fake messages which can trick the car's security systems to unlock it and disable its engine immobilizer.
The devices are available through the Dark Web and work with most 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 have discovered the CAN Injection attack recommend that all car makers address this issue in their existing models. However, these criminals will continue to steal whatever they can. We can stop this from happening by implementing mechanical safety measures such as Discloks in 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 use a gadget to jam the signal sent from the key fob when the car is locked. The device could be in the pocket of a burglar in a parking area or in a hidden spot close to the driveway that is being targeted. Owners aren't able to verify whether the vehicle is locked after pressing the lock button. Instead, thieves are able to drive off with the vehicle because the signal that normally locks the car has been blocked by the device of the criminal.
They also make use of 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 is unlocked, they can use a standard computer hacker to program an unlocked key fob to gain control over the vehicle.
To protect against this type of attack, car makers have created a variety of anti-theft gadgets. But, thieves are constantly trying to beat these measures.
They've been using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The thieves copy the unlock code of the key fob, and then start the vehicle with this fake signal.
This technique is particularly popular in the US in which many vehicles have wireless technology. Owners can start and unlock their car using a mobile application on their smartphone. This technology is likely to become increasingly popular as more and more car manufacturers attempt to connect their vehicles to owners' smartphones.
In addition to implementing anti-theft systems in vehicles, it's vital for drivers to leverage best practices when here parking their cars. It is not advisable to leave their keys in the ignition and should always secure the car when they are not in it. If possible they should also utilize a gearstick lock or steering device. They should also think about having a tracking device fitted to their car in case it gets stolen.
Flat Battery
This type of attack is more prevalent than many people believe. The thieves use cheap devices that extend the signal from your key fob in order to unlock and start your car if it is off. They then simply drive the car around the corner or onto a trailer to then drive off with it. It is possible to shield your vehicle from this by installing an interrupter switch for the starter circuit. Simpler versions come with an ON/OFF button that shuts off the circuit. It costs around $15 and is easy to install.
Car thieves are always searching for new ways to take vehicles. Police, car manufacturers and insurance companies are constantly trying to stay abreast of the latest techniques and offer better anti theft systems for modern vehicles. But that doesn't stop thieves who are able to be quick to adapt and discover ways to bypass the most up-to-date anti-theft systems.
For instance, a lot of criminals use devices that operate on the same frequency as the fob in order to block the signal. They place the device in their pockets or somewhere close to their vehicle, and it prevents the fob's lock command from reaching the car, leaving the vehicle unlocked. This can be done in a matter of minutes. The device is inexpensive and readily available online.
Another strategy is to hack the car's computer system. This is more difficult, but possible. Hackers have developed devices that plug into the diagnostic port of all vehicles and allow them to access the software. They can then program a blank fob to work. It is possible to do this on older cars also, but it's more difficult without taking out the ignition.
This method could be more popular if more vehicles are connected to drivers' mobile phones. Once a thief has the username and password to a vehicle application they can open or start the vehicle using the application. You can safeguard yourself by not leaving valuables in your car and by parking in a garage.
