Cars Being Stolen With Keyless Entry
If car owners leave their keys on the table or at their doors, they may unknowingly be allowing thieves to hijack their signal. This relay attack is a highly-tech method criminals use to steal keyless vehicles.
Keyless ignition cars emit an extremely low-power radio signal, in search of a fob that can respond. If the signal is recorded and recreated, it could be used to unlock the car and to start it.
Relay Attack
Imagine your car safely parked in your driveway, with the key fob tucked away inside your home. You're sure that your car is secure, but unseen by you sophisticated thieves are planning an heist. The thieves employ technology to hack into vehicles via digital chinks. This method of stealing vehicles with keyless access is known as relay theft.
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 on the key fob as well as in the car are programmed to only activate when they're within certain distance of each other. However, thieves can bypass this limitation with an attack known as the'relay attack'.
Two individuals are required to perform this: one person is close to the car and uses a device that captures an electronic version of the signal coming from the key fob. The other who is at home with the owner is using a second device to transmit the signal from the key fob back to the car. This trickery fools the car into believing the key fob has traveled a distance sufficient to unlock and start the vehicle.
This type of heist was once a costly process that required expensive equipment. But now, you can pick up relay transmitters for inexpensive online market and carry out the heist in just a few minutes. This is the reason it's well-liked by car thieves.
All modern cars with keys are at risk. Some cars are more vulnerable to this type of attack than others. Researchers have tested 237 popular automobiles and found that all of them are susceptible to being stolen using this method.
Tesla vehicles are supposedly less susceptible to this type of theft, but the company hasn't yet implemented UWB features that could effectively check distances on the car's signal to protect against relay attacks. The company has stated that they will implement this in the future but until then they are vulnerable. That is why it's important to be proactive about your vehicle security and install an anti-theft device that safeguards your keys and the car from such attacks.
CAN Injection Attack
Modern vehicles are designed to protect themselves from thieves by exchanging cryptographic data with the key to prove that it's authentic. This system is generally reckoned to be secure, however criminals have found a way around it. They pretend to be a smart key, transmit messages to the vehicle, and then drive away. To do that they gain access to the smart key's internal communications network.
Nowadays, the majority of cars are equipped with between 20 and 200 electronic control units (or ECUs) that control various aspects of the car's operation. They communicate via a network called CAN bus. These ECUs are put into a low power sleep mode to decrease their power consumption. This mode is activated when ECUs receive a "wake up" frame. These frames are usually sent by the ECU that manages the smart key or door. These messages are not always authenticated or encrypted. This means that thieves can intercept them with the use of a cheap and simple device.
They search for a spot that allows them to connect directly to the wires of the CAN connection. They are usually hidden within the headlights or in the front of the car, and can be accessed by removing the bumper and cutting holes in the headlamp assembly to expose the wires. The thieves then use a device called an CAN injection attacker, which is used to send fake messages which trick the car's security systems into unlocking the car and disengaging its engine immobilizer.
These devices can be bought 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 discovered the CAN Injection attack recommend that all car makers fix this in their existing models. However, these thieves will continue taking everything they can. The best thing we can do is make an effort to prevent this from happening by putting in mechanical security measures such as Discloks on all of cars and ensuring that they are always located in areas with adequate lighting that are clearly visible to passers-by.
The Signal is blocked
In a variation of the relay attack that makes use of a device, thieves can jam the signal transmitted by key fobs while the vehicle is locked. The device could be found hidden in the pocket of a burglar in a parking lot or in a hiding spot near the driveway that is being targeted. When owners press the button to lock their fobs and leave and leave, they don't have to think about whether or not the car actually locks. Instead, thieves could drive off with the vehicle since the signal that normally locks the car has been blocked by the crook's device.
The crooks also make use of devices to amplify the signal from the key fob to unlock vehicles. The crooks can accomplish this even when the key is in the driver's pocket or hanging on an outside hook in the home. Once the car is unlocked, they can make use of an ordinary diagnostic port or computer hacker to program a blank key fob and gain control of the vehicle.
To protect against this type of attack, car makers have developed a variety of anti-theft devices. However, criminals are constantly looking for ways to defeat these measures.
For instance, they've begun using devices that transmit on the same frequency as remote key fobs in order to intercept their signals. The thieves then copy the unlock code from the key fob, and then start the vehicle with this fake signal.
This technique is especially popular in the US and Europe where a large number of cars are sold with wireless technology that lets owners unlock and start their vehicles by using a mobile application on their phone. This technique is likely to become more popular as more car manufacturers attempt to connect their vehicles with their owners phones.
In addition to implementing anti-theft systems in vehicles, it's vital for drivers to follow the best practices when they park their cars. They should never leave their key fobs in the ignition, and should always ensure that their vehicle is locked completely when they're not there and should use an engine or steering wheel lock, if it is possible. They should also consider installing a tracking device on their vehicle in the event that it's stolen.
Flat Battery
This type of attack occurs more often than we think. Thieves use inexpensive devices to extend the signal from your key fob to open and start the car, even if it's switched off. Then they drive the car to a trailer or around a corner to take it away. It would be possible to shield your vehicle from this by installing a starter circuit interrupt switch. Simpler versions come with an ON/OFF button which interrupts the circuit. It costs about $15 and is simple to put in yourself.
Car thieves are constantly looking for new ways to rob vehicles. The police, car makers and insurance companies are constantly trying to keep up to their tactics and offer better anti-theft solutions for the latest cars. But this doesn't stop thieves who can be quick to adapt and find ways to circumvent the latest anti-theft technology.
Many thieves block the signal with devices that use the same radio frequency of the fob. They put the device in their pockets or in a location close to their vehicle, and it blocks the fob's lock signal from reaching the car and thereby leaving the vehicle unlocked. This can be done in a matter of seconds. The device is inexpensive and is available online.
Another strategy is to hack into the car's computer system. This is harder but still possible. All cars have a diagnostic port, and hackers have designed devices that plug into them and allow them access the software in the car. They can then program an unfinished fob to work. It is possible to do this on older cars also however it is more difficult without taking out the ignition.
As more vehicles are linked to smartphones of drivers and this method could be more popular. Once a thief has the username and password to a vehicle app they can open or start the vehicle by using the application. You can help defend yourself from these kinds of attacks by not leaving valuables in read more your car and parking it in a garage or secured parking lot.
