Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or at their door, they may unknowingly allow thieves to steal their signal. This relay attack is a sophisticated technique used by criminals to steal keyless vehicles.
All keyless ignition vehicles emit a low power radio signal to find an appropriate fob. If the signal is recorded and recreated, it could be used to unlock the car and then start it up.
Relay Attack
Imagine your car safely at your driveway, with your key fob in your home. You're sure that your car is safe, but not seen by you, sophisticated thieves are plotting an attack. Instead of breaking windows or jimmying locks, these thieves are using technology to hack into vehicles using digital cracks in their armor. This method of stealing cars with keyless access is known as relay theft.
Cars with keyless entry are designed to operate using a signal that is transmitted from the remote control (RF) transmitter to the owner's key fob. To prevent keyless entry by unauthorized individuals, the RF transmitters on the key fob and the car are programmed to turn on when they are within a specific distance of each other. However, thieves are able to override 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 to capture a digitalized version of the the key fob. The other who is at the home of the owner, uses a second gadget to transmit the signal from the key fob to the car. This trick tricked the car into thinking the key fob is close enough to unlock and start it up.
This type of heist was once a costly process that required expensive equipment. However, now you can pick up relay transmitters on the cheap online and execute a heist in minutes. This is why it's popular with car thieves.
All modern vehicles that have keyless access are vulnerable. Certain cars are more vulnerable to this kind of attack than others. In fact researchers have examined 237 vehicles that are popular and found that they could be all 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 conduct distance checks on the car's signal and stop relay attacks. The company has stated that they will implement this in the near future, however until then, they're vulnerable. Installing an anti-theft device that protects both your car and your keys against such a threat is a proactive approach to ensure your car's security.
CAN Injection Attack
Modern cars are designed to guard themselves from theft by exchanging cryptographic data with the key to prove that it's authentic. The system is generally believed to be secure, however thieves have found a way to circumvent it. They simply pretend to be the smart key and send other messages to the car, letting it unlock the doors, turn off its engine immobilizer, and then go on their way. To achieve this, they need 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) which control different aspects of the car's operation. They communicate through an electronic network known as CAN bus. To ensure that power consumption is low they ECUs enter sleep mode with low power that is activated when they receive a wake up frame. These frames are typically sent through the door or a smart key receiver ECU. However the messages aren't usually authenticated or encrypted, which means that they can be intercepted by criminals using a cheap and basic device.
To accomplish this, they search for a location that allows them to connect directly to the CAN bus wires. They are usually hidden inside the headlights or elsewhere 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 employ a device known as an CAN injection attack to send fake messages that fool the safety systems of the car to unlock and disable the engine immobilizer.
These devices are available for purchase on the Dark Web, and work for the majority of major car manufacturers which include BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and many more. The researchers who discovered this CAN Injection attack are recommending that all car makers fix the issue in their current check here models, but the reality is that thieves will continue to steal whatever they can get their hands on. The best we can do is make an effort to prevent this from happening by installing mechanical security measures like Discloks on all cars and ensuring that they are always parked in well-lit areas that are easily visible to pedestrians.
The Signal is blocked
In a variant of the relay attack that makes use of a device that can be used to block the signal transmitted by the key fob when the vehicle is locked. The device could be hidden in the pocket or hidden the location of a thief in an open parking lot or even near the driveway that is being targeted. Once owners hit the lock button on their fobs and leave, they don't think about whether or not their car is really is locked. Instead, thieves could drive off with the vehicle because 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 key fob's signals to unlock vehicles. The crooks can accomplish this even when the key is inside a pocket of a driver, or hanging on a hook inside the home. After the car is unlocked, hackers can make use of an ordinary diagnosis port to program an unlocked fob.
Car manufacturers have come up with various anti-theft devices to guard against these kinds of attacks. However, thieves are always finding ways 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 then copy the unlock code from the key fob and begin the vehicle with this fake signal.
This method is especially popular in the US where a lot of cars have wireless technology. Owners can unlock and start their vehicle through a mobile application on their smartphone. This technology is likely to increase in popularity as more companies attempt to connect their vehicles with their owners' smartphones.
In addition to installing anti-theft technologies in vehicles, it's vital for drivers to leverage best practices when parking their vehicles. They should never leave the key fobs in ignition and always lock the car when they are not in it. If possible, they should also use a steering or gearstick locking device. They should also think about installing a tracking device to their car in case it is stolen.
Flat Battery
This kind of attack occurs more often than most people realize. Thieves employ cheap devices to extend the signal from your key fob to unlock and begin the car, even if it's switched off. Then they drive the car to an unmarked trailer or around a corner and take it away. It would be possible to protect your car from this by installing an interrupter for the starter circuit. Simpler versions have an ON/OFF button which interrupts the circuit. It costs around $15 and is simple to install.
Car thieves are always working on new ways to enter vehicles and steal them. Car manufacturers, police and insurance companies are always trying to stay on top of the latest tactics and provide better anti-theft systems for modern vehicles. However, that doesn't stop thieves, who are able to be quick to adapt and discover ways to bypass the most recent anti-theft measures.
For instance, a lot of thieves use devices that operate on the same radio frequency as the fob to jam the signal. The device is put in the pocket or close by the vehicle and blocks the fob from transmitting the lock command to the vehicle. This can be done in just a few seconds. The device is inexpensive and available online.
Hacking the computer system of the car is another option. This is more difficult, but still possible. Every car has a diagnostic port, and hackers have created devices that plug into them and let them access the software in the car. They can then program an unfinished fob to function. It is possible to do this with older cars too, but it's more difficult without taking out the ignition.
As more vehicles are connected to the phones of drivers, this method may become more popular too. Once a criminal has the username and password to a vehicle app they are able to unlock or start the car using the app on their phone. You can protect yourself by not putting valuables inside your car, and by parking in a garage.
