Cars Being Stolen With Keyless Entry
If car owners place their keys on the table or near their doors, they could unknowingly allow thieves to steal their signal. This relay attack is just one of the latest techniques criminals are using to steal brand new keyless cars.
Keyless ignition cars emit an low-power radio signal that is in search of a fob that can respond. If the signal is recorded and recreated, it could be used unlock the car and start it.
Relay Attack
Imagine your car safely parked in the driveway, and the key fob safely in your home. You're sure that your car is secure, but unseen by you sophisticated thieves are planning an attack. They use technology to hack into vehicles via digital chinks. This method of stealing vehicles with keyless access is called relay theft.
Cars equipped with keyless entry are designed to operate using a signal sent from the car's remote control (RF) transmitter to the owner's key fob. To prevent keyless entry by unauthorized individuals the RF transmitters on the key fob as well as the car are programmed only to be activated when they are within a specified distance from one another. A thief, however, can circumvent this limitation employing a method known as the relay-attack.
Two people are required to do this: one person is near the car and utilizes a device to capture an electronic version of the the key fob. The other person who is at the owner's home is using a second device to transmit the signal from the key fob to the car. This trickery tricks the car into believing that the key fob has reached an adequate distance to allow it to be opened and started the vehicle.
This type of heist was once a costly process that required expensive equipment. It is now possible to purchase an inexpensive relay transmitter online and pull off a heist within minutes. This is the reason it's popular with car thieves.
While some cars are less vulnerable to this type of theft than others, all modern vehicles that have keyless entry are vulnerable. Researchers have tested 237 of the most popular cars and found that every one of them could be taken through this method.
Tesla vehicles are said to be less susceptible to this kind of theft. However Tesla hasn't implemented UWB technology that would allow it to conduct distance checks and stop attacks via relay. The company has stated that they will do so in the future, but for now, they remain vulnerable. Installing an anti-theft device that protects both your car and your keys against these types of attacks is a proactive way to ensure the security of your vehicle.
CAN Injection Attack
Modern cars are designed to protect themselves from theft by exchanging cryptographic messages with the key to prove it's genuine. This method is generally thought to be secure, but criminals have found a way to circumvent it. They pretend to be the smart key, then send messages to the vehicle, and then drive off. To do this they have access to the smart key's internal communication network.
These days, most cars are equipped with between 20 to 200 electronic control units (or ECUs) that control various aspects of the car's operation. They communicate with one another using a network known 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 a "wake up" frame. These frames are typically sent by the ECU that controls the smart key or door. However the messages aren't usually encrypted or authenticated, which means that they can be intercepted by criminals using a cheap and simple device.
To accomplish this, they must look for a location where they can 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 gain access to them, you can remove the bumper and make holes in the headlamp assemblies. The thieves then employ a device known as a CAN injection attacker to send out fake messages that can trick the car's security systems to unlock it and disable the engine immobilizer.
The devices are available for purchase on the Dark Web, and work for most of the major car makers including BMW, Cadillac, Chrysler, Fiat, Ford, Honda, Hyundai, Jaguar, Jeep, Lexus, Nissan, Renault, Toyota, Volkswagen, Maserati, and more. Researchers who discovered the CAN Injection attack recommend that all car makers fix the issue in their current models. However, these criminals will continue taking whatever they can. We can stop this from happening by installing mechanical security measures, such as Discloks inside all of our cars and parking them in well-lit, well-lit areas.
Blocking the Signal
In a variant of the relay attack that uses a gadget, thieves can jam the signal transmitted by key fobs while the vehicle is locked. The device could be 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. Once owners hit the button to lock their fobs, and then walk away, they don't think about whether or not their car is actually locks. Instead, thieves could drive off with the vehicle since the signal that normally locks the car has been blocked by the device of the criminal.
The crooks also use devices to amplify the signal from the key fob in order to unlock vehicles. They may even do this when the key is in the pocket of the driver or hanging from a hook in the house. After the car is unlocked, hackers can use the standard diagnostic port to create an unlocked fob.
Car manufacturers have come up with a variety of anti-theft solutions to protect against these types of attacks. However, thieves are always finding ways to beat these measures.
They've been using devices that transmit at the same frequency as remote keyfobs to intercept signals. The crooks can then copy the unlock code of the key fob and then start the car using this fake signal.
This method is especially popular in the US where a lot of cars are equipped with wireless technology. Owners can start and unlock their car by using a mobile app from their mobile. This technique is likely to be more commonplace as more car manufacturers attempt to connect their cars to their owners phones.
It is crucial that drivers follow the best practices to park their vehicles. It is not a good idea to leave keys in the ignition. They should always make sure the vehicle is locked completely when they're not using it and should make use of the steering wheel or a gearstick lock if possible. They should also think about installing a tracking device onto their vehicle in the event it is stolen.
Flat Battery
This kind of attack happens more often than most people realize. The thieves employ cheap devices that extend the signal of your key fob to enable it to unlock and start your car, even in the event that it is off. They then drive the car around a corner or onto a trailer to then drive off with it. Installing an interruption switch to the starter circuit can protect your vehicle from this. Simpler versions include website 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 looking for new ways to gain access to vehicles and take them away. The police as well as car manufacturers and insurance companies are constantly trying to catch up with their strategies and develop better anti-theft systems for modern cars. But this isn't stopping thieves who easily adapt and find ways to circumvent the most recent anti-theft measures.
Many thieves jam the signal by using devices that use the same radio frequency as the fob. They place the device in their pocket or in a location close to their vehicle, and it prevents the fob's lock signal from reaching the vehicle which leaves the vehicle unlocked. This can be accomplished in just a few seconds. The device is inexpensive and easily accessible online.
Another tactic is to hack into the car's computer system. This is harder but still feasible. Every car has an diagnostic port and hackers have designed devices that plug into them and let them access the software of the car. From there, they are able to program the blank key fob to start working. It is possible to do this on older cars also but it's more difficult if you remove the ignition.
This method could become more popular as more vehicles are connected with drivers' phones. Once a criminal has the username and password to the vehicle app they are able to open the car or get it started by using the app on their phone. Fortunately, you can protect yourself from these types of attacks by not putting valuables in your car and putting it in a garage or secure parking lot.
