Cars Being Stolen With Keyless Entry
Car owners who toss keys on tables or near their front doors could be allowing thieves to hijack the signal. This relay attack is one of the advanced methods criminals are using to steal new keyless cars.
All keyless ignition vehicles emit a low-power radio signal that is used to locate a matching fob. If the signal is captured and recreated, it can be used unlock the car, and also to start it.
Relay Attack
Imagine your car safely parked in the driveway, with the key fob safely inside your home. You're confident that your car is safe, but unnoticed by you, sophisticated thieves are plotting an attack. The thieves employ technology to snoop on vehicles through digital chinks. This method of stealing cars with keyless access is called relay theft.
The keyless entry system in cars is controlled by a signal from the car's RF transmitter to the key fob. To stop unauthorized keyless entry the RF transmitters inside the key fob as well as in the car are programmed to activate only when they're within certain distance of each other. However, thieves can bypass this restriction by employing a method known as the relay-attack.
Two individuals are required to perform this: one person stands near the car and utilizes a device to capture digitally the the key fob. The other, who is at the house of the owner is using a different device to transmit the key fob signal back down to the car. This trick tricks the car into thinking the key fob is near enough to unlock and start it up.
This type of heist used to require expensive equipment. It is now possible to purchase an inexpensive relay transmitter online and pull off an heist in a matter of minutes. This is why it's so popular with car thieves.
All modern cars with keys are at risk. Certain cars are more vulnerable to this type of attack than others. Researchers have examined 237 well-known automobiles and found that all of them can be stolen by this method.
Tesla vehicles are believed to be less prone to this kind of theft. However Tesla 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. That's why it's essential to take a proactive approach to your car security and install an anti-theft device that protects your keys and car from these types of attacks.
CAN Injection Attack
Modern vehicles are designed to guard themselves from thieves by transferring cryptographic messages using the key to prove that it's authentic. The system is believed to be secure, however criminals have found ways to circumvent it. They pretend to be a smart key, send messages to the vehicle, and then drive off. To do this they have access to the smart key's internal communication network.
Today, most automobiles are equipped with between 20 and 200 electronic control units (or ECUs) that control various aspects of the car's operation. They communicate with each other via a network known as CAN bus. These ECUs are put into a low power sleep mode to reduce their power consumption. This mode is activated when ECUs receive a "wake up" frame. These frames are typically sent by the ECU that is in charge of the smart key or door. However they aren't always authenticated or encrypted so they can be intercepted by criminals with a cheap and basic device.
They search for a spot that allows them to connect directly to the wires for CAN connection. These are often hidden away inside the headlights or elsewhere in front of the car, and can be accessed by removing the bumper and cutting holes in the headlamp assembly to expose them. The thieves use the device referred to as an CAN injection attack. It is used to send out fake messages that trick the car's safety systems into unlocking and disengaging the engine immobilizer.
These devices are available for purchase on the Dark Web, and work for most of the major car manufacturers including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and more. The researchers who discovered this CAN Injection attack are recommending that all car makers fix it in their existing models, but the reality is that thieves will continue to take anything they can get their hands on. We can stop this by installing mechanical security measures, such as Discloks inside all of our cars and parking them in well-lit, well-lit areas.
Jamming the Signal
In a website variation of the relay attack, which makes use of a device that can be used to block the signal sent by key fobs while the vehicle is locked. The device could be hidden in the pocket or in the hiding place of a thief on the parking lot, or in the driveway being targeted. When owners press the lock button on their fobs, and then walk away they don't consider whether or not the car is really locked. Instead, thieves can drive off 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 amplify the key fob's signals to unlock vehicles. They can do this while the key is in the driver's pocket or hanging from its hook in the house. Once the car is locked, they can use a standard diagnostic port or computer hackers to program the blank key fob and gain control over the vehicle.
To guard against this kind of attack, car makers have created a variety of anti-theft gadgets. However, thieves are always trying to beat these measures.
For instance, they've been using devices that transmit on the same frequency as remote key fobs in order to intercept their signals. The thieves can then copy the key fob's unlock code and start the car with this fake signal.
This method is particularly popular in the US and Europe where a large number of automobiles are sold with wireless technology that lets owners unlock and start their vehicles by using a mobile application on their smartphone. This technology is expected to become more popular as more and more companies attempt to connect their vehicles to their owners' smartphones.
It is essential that drivers use best practices to park their cars. They should never leave the keys in ignition and lock the car when not in it. If possible they should also utilize a gearstick lock or steering device. They should also think about installing a tracking device to their car in case it's stolen.
Flat Battery
This type of attack is more common than many people believe. The thieves use low-cost devices that increase the signal of your key fob to enable it to unlock and start your car if it is off. Then they drive the car to an unmarked trailer or around a corner to take the vehicle away. Installing an interruption switch to the starter circuit can protect your vehicle from this. The simplest ones just have an ON/OFF switch that shuts off the starter circuit. It costs about $15 and is simple to put in yourself.
Car thieves are always searching for new ways to take vehicles. Police, car manufacturers and insurance companies are always trying to stay abreast of the latest tactics and provide more effective anti-theft systems for modern vehicles. However, this isn't stopping thieves who easily adapt and find ways to bypass the most recent anti-theft measures.
For example, many criminals employ devices that operate on the same frequency as the fob in order to block the signal. They put the device in their pockets or close to their vehicle, and it prevents the fob's lock signal from reaching the car and thereby leaving it unlocked. This can be done in seconds. The device is inexpensive and easily available online.
Another strategy is to hack the car's computer system. This is more difficult but nevertheless possible. Every car has a diagnostic port, and hackers have designed devices that connect to them and let them access the software in the car. From there, they are able to program a blank key fob and make it work. It is possible to do this on older cars also but it's more difficult without removing the ignition.
As more vehicles are connected to the phones of drivers and this method could be more popular. Once a criminal has the username and password to a vehicle app and then they can unlock or start the car by using the app on their phone. You can protect yourself by not leaving valuables in your car and also by parking in garages.
