Cars Being Stolen With Keyless Entry
If car owners throw their keys on the table or next to their doors, they could not realize that they are allowing thieves to steal their signal. This relay attack is just one of the high-tech methods criminals are using to steal new keys from cars.
Keyless ignition vehicles emit an low-power radio signal that is seeking a compatible fob that can respond. If the signal is recorded and recreated, it could be used unlock the car and to start it.
Relay Attack
Imagine your car safely parked in the driveway, and the key fob sitting safely inside your home. You're confident that your vehicle is safe, but unnoticed by you, sophisticated thieves are plotting an attack. Instead of slamming windows and jiggling locks, thieves are using technology to hack into vehicles using digital cracks in their armor. Known as relay theft, it's a more common way to steal cars with keyless entry.
The keyless entry system that is found in cars is controlled by a signal from the car's RF transmitter to the key fob. To prevent keyless entry by unauthorised persons the RF transmitters on the key fob as well as the car are programmed to turn on when they are within a specified distance of each other. A thief, however, can bypass this restriction by using a technique known as the relay-attack.
Two people are required to do this: one stands near the car and uses a device to capture digitally the the key fob. The other, in the vicinity of the house of the owner, uses a second device to send the key fob signal back down to the car. This trick tricks the car into believing that the key fob has reached a distance sufficient to allow it to be opened and started the vehicle.
In the past, this kind of heist required expensive equipment to carry out. But now, you can buy a relay transmitter on the cheap online and execute a heist in minutes. This is the reason car thieves are enthralled by it.
All modern cars with keys are at risk. Certain cars are more vulnerable to this type than others. In fact researchers have examined 237 vehicles that are popular and found that they can be all stolen using this method.
Tesla vehicles are believed to be less prone to this kind of theft. However, the company hasn't yet implemented UWB technology that would enable it to perform distance checks and stop attacks via relay. The company has stated that they'll implement this in the near future, but until then, they're vulnerable. That is why it's important to take a proactive approach to your security in your car and install an anti-theft device that protects your keys and the car from such attacks.
CAN Injection Attack
Modern vehicles are designed to shield themselves from theft by exchanging cryptographic messages with the key to prove it's authentic. This system is generally reckoned to be secure, but criminals have found a way around it. They can impersonate the smart key, and send other messages to the car letting it unlock the doors, turn off its engine immobilizer, then let them leave the car. To do this, they get access to the smart key's internal communications network.
Nowadays, the majority of automobiles are equipped with between 20 to 200 electronic control units (or ECUs) that control various aspects of the car's operation. They communicate with each other using the CAN bus. These ECUs enter a low-power sleep mode to reduce their power consumption. This mode is activated when ECUs receive an "wake up" frame. These frames typically come through the door or a smart key receiver ECU. However the messages aren't usually encrypted or authenticated and, therefore, could be snatched by criminals with a cheap and basic device.
To accomplish this, they must look for a place that allows them to connect directly to the CAN bus connection wires. They usually hide in the headlights, or in other areas of the front of the vehicle. To access them, you must remove the bumper and cut holes in the headlamp assemblies. The thieves employ an instrument known as a CAN injection attack to send fake messages which trick the car's safety systems to unlock and disable the engine immobilizer.
The devices are available on the Dark Web and work with the majority of major car manufacturers, including BMW and Cadillac, Chrysler, Fiat and Ford, Honda, Hyundai and Jeep, Lexus and Nissan, Renault and Toyota, Volkswagen and Maserati. The researchers who discovered this CAN Injection attack are recommending that all car makers fix the issue in their current models, but the reality is that thieves will continue to grab anything they can get their hands on. The best thing we can do is try and prevent this by installing mechanical security measures like Discloks on cars, and making sure that they are parked in well-lit areas that are clearly visible to passers-by.
The Signal is blocked
In a variant of the relay attack, which employs a device that can be used to block the signal from a key fob while the car is locked. The device may be inside the pocket of a burglar in a parking space or in a hideout close to the driveway that is being targeted. Owners aren't able to verify whether read more the car is locked after pressing the lock button. Instead, thieves could take off with the car since the signal that normally locks the car is blocked by the crook's device.
They also use devices that amplify signals from the key fob to unlock vehicles. The crooks are able to do this even if the key is in a driver's pocket, or hanging on a hook inside the home. When the car is unlocked, they can use an ordinary diagnostic port or computer hackers to program an unlocked key fob to gain control of the vehicle.
To guard against this kind of attack, car makers have created a variety of anti-theft devices. But, as always, thieves come up with new ways to beat these measures.
They've started using devices that transmit at the same frequency as remote keyfobs to intercept signals. The thieves can then copy the key fob's unlock code and then start the car using this fake signal.
This method is especially popular in the US in which many vehicles have wireless technology. Owners can unlock and start their vehicle through a mobile application on their smartphone. This technology is likely to be more commonplace as more manufacturers try to link their cars with their owners phones.
It is important that drivers follow the right procedures to park their vehicles. They shouldn't leave their key fobs in the ignition, should always ensure that the car is fully locked when they're not using it and should utilize an engine or steering wheel lock if possible. They should also consider having a tracking device fitted to their car in the event it's stolen.
Flat Battery
This kind of attack occurs more often than we think. The thieves employ inexpensive devices that extend the signal of your key fob in order to unlock and start your car, even when it's off. Then they drive the car to the trailer or around a corner, and take the car away. It would be possible to protect your vehicle from this by installing an interrupter switch for the starter circuit. Simpler versions include an ON/OFF button that shuts off the circuit. It's priced at around $15 and is simple enough to install yourself.
Car thieves are always seeking new ways to rob vehicles. Car manufacturers, police and insurance companies are always trying to keep up with the latest tactics and provide better anti theft systems for modern vehicles. But that doesn't stop thieves, who are able to adapt quickly and find ways to circumvent the latest anti-theft measures.
Many thieves block the signal with devices that use the same radio frequency of the fob. They place the device in their pockets or in a location close to their vehicle, and it blocks the fob's lock command from reaching the car, leaving it unlocked. This can be done in a matter of seconds. The device is affordable and can be purchased online.
Another strategy is to hack the car's computer system. This is more difficult but feasible. Hackers have created devices that plug into the diagnostic port of all cars and allow them to connect to the software. From there, they are able to program an unfinished key fob and start working. It is possible to do this on older vehicles also but it's more difficult without removing the ignition.
This technique could be more popular if more vehicles are connected to drivers' phones. 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 guard yourself by not putting valuables inside your car, and also by parking in garages.
