Cars Being Stolen With Keyless Entry
Car owners who throw keys on tables or near their front door could be giving thieves the ability to take over the signal. This relay attack is a highly-tech method used by criminals to steal new keyless vehicles.
All keyless ignition cars emit a low-power radio signal seeking a compatible fob to respond. If the signal is captured and recreated it can be used to unlock the car and start it up.
Relay Attack
Imagine your car safely parked in your driveway, with the key fob safely inside your home. You may be confident that your vehicle is secure but sophisticated thieves are planning a heist without you being aware. Instead of breaking windows or jimmying locks, thieves are using technology to hack into cars via digital cracks in their armor. Also known as relay theft, it's an increasingly common way to steal cars that have keyless entry.
The keyless entry system found in cars is controlled by a signal by the car's RF transmitter to the key fob. To ensure that keyless entry is not unauthorized, the RF transmitters in the key fob and car are programmed to only activate when they're within certain distance from one another. The thief is able to circumvent this restriction using a technique known as the relay-attack.
Two individuals are required to perform this: one stands near the car and uses a device that captures digitally the the key fob. The other who is at the owner's home is using a second device to transmit the signal from the key fob to the car. This trickery fools the car into thinking the key fob is near enough to be able to unlock it and start it up.
In the past, this kind of heist required expensive equipment to perform. Now, you can purchase a relay transmitter on the inexpensive online market and carry out a heist in minutes. This is the reason it's well-liked by car thieves.
While certain vehicles are less vulnerable to this type of theft than others, all modern cars with keyless entry are at risk. Researchers have tested 237 popular automobiles and found that all of them are susceptible to being stolen using this method.
Tesla vehicles are said to be less vulnerable to this kind of theft. However Tesla hasn't yet implemented UWB technologies that would allow it to perform distance checks and prevent attacks via relay. The company has said that they'll implement this in the near future, but until then, they are vulnerable. That is why it's important to adopt a proactive approach to your vehicle security and install an anti-theft device that safeguards your keys and the car from such attacks.
CAN Injection Attack
Modern cars can guard themselves from thieves by sending encrypted messages to the key to confirm its authenticity. The system is generally believed to be secure, however thieves have found a way around it. They impersonate a smart key, transmit messages to the vehicle and then drive off. To do this, they gain access to the smart keys' internal communication network.
Nowadays, the majority of cars are equipped with between 20 to 200 electronic control units (or ECUs) that manage different aspects of the car's operation. They communicate with each other using a network known as CAN bus. These ECUs are put into a low power sleep mode to decrease their power consumption. This mode is activated when ECUs receive an "wake up" frame. These frames are typically sent by the ECU that manages the smart key or door. These messages are not always authenticated or encrypted. This means that thieves can take them over with a simple and cheap device.
They search for a location that allows them to connect directly to the wires of the CAN connection. They're usually hidden in the headlights or in the front of the car, and can be accessed by pulling the bumper off and cutting holes in the headlamp assembly to expose the wires. The thieves employ a device known as an CAN injection attack. It is used to send out fake messages that trick the car's safety systems to unlock and disable the engine immobilizer.
The devices are available for sale on the Dark Web, and work for most of the major car manufacturers which include BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and more. Researchers who have discovered the CAN Injection attack recommend that all car makers address the issue in their current models. However, these criminals will continue taking everything they can. We can stop this by installing mechanical safety measures, such as Discloks inside every car we own and parking them in well-lit, visible areas.
The Signal is blocked
In a variation of the relay attack, which employs a device that is able to block the signal sent by a key fob while the car is locked. The device could be hidden in the pocket of a thief in a parking area 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 think about whether or not their car is actually locks. Instead, thieves are able to drive off with the vehicle because the signal that normally locks the car is blocked by the crook's device.
The crooks also use devices to amplify the key fob's signals to unlock vehicles. The crooks are able to do this even if the key is in the pocket of a driver, or hanging on an outside hook in the home. Once the car has been unlocked, hackers can make use of the standard diagnostic port to create an unlocked fob.
Car manufacturers have developed various anti-theft devices to safeguard against these types of attacks. But, thieves are constantly looking for ways to defeat these measures.
They've begun using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The thieves copy the unlock code from the key fob and begin the vehicle with this fake signal.
This method is particularly popular in the US in which many vehicles come with wireless technology. Owners can start and unlock their car using a mobile application on their smartphone. This technology is expected to become increasingly popular as more and more companies try to connect their vehicles to owners' smartphones.
In addition to implementing anti-theft systems in vehicles, it's vital for drivers to follow the best practices when they park their vehicles. It is not advisable to leave the key fobs in ignition and should always secure the car when they are not in it. If they can, they should also use a gearstick lock or steering device. They should also consider installing a tracking device onto their vehicle in the event that it is stolen.
Flat Battery
This kind of attack is more frequent than many people believe. Thieves use inexpensive devices to extend the signal from your key fob to open and start cars even if they're switched off. They then simply drive the car around the corner or onto a trailer to leave with it. It is possible to protect your vehicle from this by installing an interrupter switch for the starter circuit. Simpler versions come with an ON/OFF button which interrupts the circuit. It is priced at around $15 and is easy to install.
Car thieves are always looking for new ways to enter vehicles and steal them. Car manufacturers, police and insurance companies are always 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 find ways to get around the latest anti-theft measures.
For instance, many thieves use devices that operate on the same radio frequency as the fob to block the signal. They place the device in their pockets or close to their vehicle, and it prevents the fob's lock command from reaching the car, leaving the vehicle unlocked. This can be accomplished in a matter of minutes. The device is cheap and is available online.
Hacking the computer system of the car is an alternative option. This is more difficult, but it is still possible. Every car has an diagnostic port, and hackers have developed devices that connect to them and let them access the car's software. They can then program a blank fob to function. This can also be done on older cars, although it is more difficult to do without removing the ignition lock.
This method is likely to be more popular if more vehicles are connected with drivers' phones. Once a burglar has the username and password to a vehicle app they can open or start check here the vehicle using the app. It is possible to protect yourself from these types of attacks by not leaving valuables in your car and putting it in a garage or secure parking lot.
