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 just one of the latest techniques criminals are using to steal brand new keyless cars.
All keyless ignition vehicles emit a low-power radio signal to locate the fob that matches. If the signal can be captured and recreated, it can be used to unlock the car and to start it.
Relay Attack
Imagine your car safely in your driveway, and your key fob inside your home. You may think your car is secure, but sophisticated thieves are planning a heist, without you being aware. Instead of slamming windows or jiggling locks, they are leveraging technology to gain access to cars through digital chinks in their armor. Known as relay theft, it's a more common way to steal cars with keyless entry.
The keyless entry system found in cars is controlled by a signal sent by the car's RF transmitter to the key fob. To prevent unauthorized keyless entry the RF transmitters inside the key fob and in the car are programmed to only activate when they're within a specific distance of each other. However, a thief can bypass this limitation with a technique called the 'relay attack'.
To accomplish this, two people work in tandem one is positioned by the car, using the device that captures digitally the key fob's signal. The other, who is at the owner's house, uses a second device to transmit the key fob signal back to the car. This trickery tricks the car into believing that the key fob has traveled the distance needed to allow the vehicle to start and unlock. vehicle.
In the past, this type of heist required expensive equipment in order to execute. Today, you can purchase a cheap relay transmitter online and pull off a heist within minutes. This is the reason car thieves are enthralled by it.
While certain cars are less prone to this kind of theft than others, all cars with keyless entry are vulnerable. Researchers have examined 237 well-known automobiles and found that all of them could be taken by this method.
Tesla cars are said to be less susceptible to this type of theft, however, the company has not yet implemented UWB features that would effectively perform distance checks on the car's signal and protect against relay attacks. The company has said that they'll implement this in the future but until then, they're vulnerable. That's why it's essential to take a proactive approach to your vehicle security and install an anti-theft kit that safeguards your keys and car from these types of attacks.
CAN Injection Attack
Modern vehicles can defend themselves from theft by sending encrypted messages to the key to prove its authenticity. This method is generally thought to be secure, however criminals have found a way around it. They just pretend to be the smart key and send other messages to the vehicle letting it unlock the doors, turn off its engine immobilizer, then let them leave the car. To do this they gain access to the smart key's internal communications network.
Today, most cars 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 the CAN bus. To keep power consumption low the ECUs go into the sleep mode at low power. This mode is activated when they receive a 'wake up' frame. These frames typically come from the door or smart key receiver ECU. However the messages aren't usually encrypted or authenticated, which means that they could be snatched by criminals using a cheap and simple device.
To do this, they look for a place that allows them to connect directly to the CAN bus connector wires. They usually are hidden in the headlights or in other areas of the front of the vehicle. To access them, you must remove the bumper and make holes in the headlamp assemblies. The thieves employ the device referred to as an CAN injection attack. It is used to send fake messages which trick the car's safety systems to unlock and disable the engine immobilizer.
These devices are available for sale on the Dark Web, and work for the majority of major car makers including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, more info Maserati, and many 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 these thieves will continue to grab everything they can lay their hands on. We can stop this from happening by implementing mechanical safety measures, such as Discloks inside all our vehicles and parking them in well-lit, visible areas.
Blocking the Signal
In a different variant of the relay attack, thieves can use a gadget to jam the signal that is sent by a key fob when the car is locked. The device could be found inside the pocket of a burglar in a parking space or in a hideout near the driveway that is being targeted. Owners don't check whether their car is locked after pressing the lock button. The device used by the criminal interferes with the signal to lock the car. Thus, thieves are able to leave the vehicle.
The crooks also use devices to amplify the signal from the key fob to unlock vehicles. The crooks can do this even if the key is in a pocket of a driver, or hanging on a hook inside the home. Once the car has been locked, hackers can use the standard diagnostic port to create an unlocked fob.
Car manufacturers have come up with various anti-theft devices to protect against these types of attacks. However, thieves are always looking for ways to defeat these measures.
For instance, they've been using devices that transmit on the same radio frequency as remote key fobs to intercept their signals. The crooks can then copy the unlock code of the key fob and then start the car using this fake signal.
This technique is particularly popular in the US in which many vehicles are equipped with wireless technology. Owners can unlock and start their vehicle by using a mobile app on their smartphone. This technique is likely to be more commonplace as more car manufacturers attempt to connect their vehicles with their owners smartphones.
It is important that drivers follow the right procedures to park their vehicles. They should never leave the keys in ignition and secure the car when not in it. If they can they should also utilize a steering or gearstick locking device. They should also think about fitting a tracking device to their vehicle in case it is stolen.
Flat Battery
This type of attack is more prevalent than people think. Thieves make use of cheap 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 a corner or onto a trailer to take off with it. Installing an interruption switch to the starter circuit will protect your vehicle from this. Simpler versions have an ON/OFF button that interrupts the circuit. It costs about $15 and is simple to install by yourself.
Car thieves are constantly seeking new ways to rob vehicles. The police as well as the car makers and insurance companies are constantly trying to keep up with their strategies and develop better anti-theft systems for modern vehicles. But this isn't stopping thieves who be quick to adapt and find ways to circumvent the latest anti-theft technology.
For instance, many thieves use devices that operate on the same frequency as the fob to jam the signal. The device is placed in the pocket or close by the vehicle and prevents the fob from transmitting the signal to the car. This can be done within just a few seconds. The device is inexpensive and is available on the internet.
Another tactic is to hack the car's computer system. This is harder but still feasible. All cars have an diagnostic port and hackers have developed devices that connect to them and let them access the car's software. From there, they are able to program an unfinished key fob and start working. It is also possible to do this on older cars, although it is more difficult to do without removing the ignition lock.
This method could become more popular as more vehicles are connected to drivers' mobile phones. Once a thief gets the username and password to a vehicle app, they can then unlock or start the car by using the app on their phone. You can safeguard yourself by not leaving valuables inside your car, and parking in garages.
