Cars Being Stolen With Keyless Entry
If car owners leave their keys on the table or at their doors, they could not realize that they are allowing thieves to steal their signal. This relay attack is a sophisticated technique used by criminals to steal keys from new vehicles.
All keyless ignition cars emit a low-power radio signal in search of a fob to respond. If the signal is recorded and recreated, it could be used unlock the car and start it.
Relay Attack
Imagine your car safely at your driveway, with your key fob in your home. You may think your car is safe however, sophisticated thieves are planning a heist without you even knowing. The thieves employ technology to snoop on vehicles through digital chinks. Known as relay theft, it's an increasingly common method of stealing vehicles with keyless entry.
The keyless entry system that is 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 and car are programmed to activate only when they're within certain distance from one another. A thief, however, can circumvent this limitation using a technique known as 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 home of the owner, uses a second device to send the key fob signal back down to the car. This trick tricks the car into thinking that the key fob has reached the distance needed to allow the vehicle to start and unlock. vehicle.
In the past, this kind of attack required expensive equipment to perform. Now, you can pick up relay transmitters on the inexpensive online market and carry out the heist in just a few minutes. This is why car thieves are enthralled by it.
While some cars are less vulnerable to this kind of theft than others, all modern cars with keyless entry are vulnerable. Researchers have tested 237 popular cars and found that all of them could be taken using this method.
Tesla vehicles are said to be less susceptible to this kind of theft. However Tesla hasn't yet implemented UWB technologies that would allow it to conduct distance checks and stop relay attacks. The company has said that they will do this in the near future, however until then, they're vulnerable. Installing an anti-theft device that protects both your keys and your car against such a threat is a proactive approach to ensure the security of your car.
CAN Injection Attack
Modern vehicles are designed to shield themselves from thieves by transferring cryptographic messages using the key to prove it's authentic. The system is considered to be secure, however thieves have found ways around it. They just impersonate the smart key and send messages to the car letting it unlock the doors, turn off its engine immobilizer, and then drive away. To do that, they get access to the smart key's internal communication network.
These days, most cars are fitted 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 an electronic network referred to 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 an "wake up" frame. These frames are usually sent from the door or smart key receiver ECU. These messages aren't always authenticated or encrypted. This means that criminals are able to intercept them with the use of a cheap and simple device.
To accomplish this, they search for a location that allows them to connect directly to the CAN bus wires. They are usually hidden within the headlights or in the front of the car, and are accessible by pulling the bumper and cutting holes in the headlamp assembly to expose them. The thieves then use a device called an CAN injection attacker, which is used to send fake messages that trick the car's security systems into unlocking it and disengaging the engine immobilizer.
The devices are available on 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 fix the issue in their current models. However, the thieves will continue taking everything they can. We can prevent this by implementing mechanical safety measures like Discloks in every car we own and parking them in well-lit, visible areas.
Jamming the Signal
In a variation of the relay attack, which makes use of a device that can be used to block the signal sent by the key fob when the car is locked. The device could be hidden in the pocket or in the hiding where a burglar is hiding on a parking lot, or even near the driveway that is being targeted. The owners don't know if the vehicle is locked after pressing the lock button. Instead, thieves can take off with the car because the signal that normally locks the car is blocked by the crook's device.
The crooks also employ devices to amplify the signal from the key fob in order to unlock vehicles. The crooks are able to do this even when the key is in the pocket of a driver, or hanging on a hook inside the home. When the car is unlocked, they can use the standard diagnostic port or computer hacker to program the blank key fob and gain control of the vehicle.
To safeguard against this kind of attack, car makers have created a variety of anti-theft devices. However, thieves are always 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 then copy the unlock code of the key fob, and then start the vehicle using this fake signal.
This technique is particularly popular in the US, where many cars have wireless technology. Owners can start website and unlock their car using a mobile application on their phone. This technique is likely to be more commonplace as more car manufacturers attempt to connect their cars to their owners smartphones.
In addition to implementing anti-theft systems in vehicles, it's crucial for drivers to use the best practices when parking their vehicles. It is not advisable to leave the keys in ignition and should always lock the car when not in it. If possible they should also utilize the gearstick or steering locking device. They should also think about having a tracking device fitted to their car in the event it's stolen.
Flat Battery
This type of attack is more common than most people realize. Thieves use cheap devices to extend the signal from your key fob to unlock and start cars even if they're switched off. Then they drive the car to the trailer or around a corner to take the vehicle away. Installing a starter circuit interruption switch will protect your vehicle from this. The simplest ones just have an ON/OFF switch that interrupts the starter circuit. It costs around $15 and is easy to install.
Car thieves are constantly looking for new ways to rob vehicles. Car manufacturers, police and insurance companies are always trying to stay abreast of the latest methods and offer better anti theft systems for modern vehicles. But this isn't stopping thieves who be quick to adapt and find ways to bypass the latest anti-theft technology.
For example, 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 in a location close to their vehicle, and it prevents the fob's lock signal from reaching the vehicle, leaving the vehicle unlocked. This can be done in a matter of seconds. The device is cheap and readily available on the internet.
Another option is to hack into the car's computer system. This is more difficult, but possible. Hackers have created devices that plug into the diagnostic port of all vehicles and allow them to access the software. From there, they can program a blank key fob and get it to work. This is also possible on older cars, although it is more difficult to do so without removing the ignition lock.
As more vehicles are linked to drivers' phones, this method may be more popular. Once a criminal has access to the username and password to a vehicle application, they can unlock or start the vehicle with the app. You can protect yourself by not leaving valuables in your car and also by parking in a garage.
