Cars Being stolen car key fob With Keyless Entry

Car owners who leave their keys on tables or in front of their front door could be allowing thieves to hijack the signal. This relay attack is just one of the high-tech methods criminals are employing to steal new keyless cars.

Keyless ignition vehicles emit a low power radio signal that is used to locate a matching fob. If the signal is recorded and recreated, it could be used to unlock the car and begin it up.

Relay Attack

Picture your car parked securely in the driveway, with the key fob sitting safely inside your home. You're sure that your car is secure, but unseen by you, sophisticated thieves are plotting an heist. They use technology to snoop on vehicles through digital chinks. Known as relay theft, it's an increasingly common way to steal cars with keyless entry.

The keyless entry system found in cars is controlled by a signal sent by the stolen car key replacement's radio transmitter to the key fob. To stop keyless entry by unauthorised persons the RF transmitters on the key fob and the car are programmed to activate when they are within a specified distance from each other. The thief can circumvent this limitation employing a technique called the "relay-attack".

Two individuals are required to perform this: one person is near the car and uses a device to capture digitally the the key fob. The other, standing by the house of the owner, uses a second device to transmit the key fob signal back down to the car. This trickery fools the car into thinking the key fob is close enough to allow it to unlock and begin the engine.

In the past, this kind of attack required expensive equipment to carry out. However, now you can buy a relay transmitter on the low cost online and conduct an heist in a matter of minutes. This is the reason why car thieves love it.

All modern vehicles that have keys are at risk. Certain cars are more vulnerable to this kind of attack than others. In fact researchers have examined 237 popular cars and found that they can be targeted by this method.

Tesla vehicles are believed to be less vulnerable to this kind of theft. However, the company hasn't yet implemented UWB technologies that would allow it to perform distance checks and stop relay attacks. The company has stated that they'll implement this in the future but until then, they are vulnerable. Installing an anti-theft device that guards your car and your keys against these types of attacks is a proactive approach to ensure the security of your vehicle.

CAN Injection Attack

Modern cars are designed to guard themselves from theft by transferring cryptographic messages using the key to prove that it's genuine. The system is generally believed to be secure, however thieves have found a way to circumvent it. They fake the identity of a smart key, send messages to the vehicle, and then drive away. To achieve this, they need access to the smart my keys were stolen' internal communication network.

These days, most cars are fitted with between 20 and 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. To reduce power consumption, these ECUs go into the sleep mode at low power. This mode is activated when they receive a 'wake up frame. These frames are typically sent from the door or smart key receiver ECU. However they aren't always encrypted or authenticated so they can be intercepted by criminals using a cheap and basic device.

They search for a spot that allows them to connect directly to the CAN connection wires. These are often hidden away inside the headlights or elsewhere in the front of the car and can be accessed by pulling the bumper off and cutting holes in the headlamp assembly to expose the wires. The criminals then employ a device dubbed an CAN injection attacker, which is used to send fake messages that can trick the car's security systems to unlock it and disable its engine immobilizer.

These devices can be bought on the Dark Web and work with most major car stolen after losing keys 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 address the issue in their current models, but the reality is that thieves will continue to take anything they can get their hands on. The best we can do is try and prevent this by installing mechanical security measures like Discloks on our vehicles, and making sure that they are always located in areas with adequate lighting that are easily visible to pedestrians.

The Signal is blocked

In a variation of the relay attack, which makes use of a device that is able to block the signal sent by a key fob while the vehicle is locked. The device could be hidden in the pocket or hiding place of a thief on the parking lot, or in the driveway being targeted. Once owners hit the lock button on their fobs and walk away and leave, they don't have to think about whether or not their car is really is locked. Instead, thieves can drive off with the vehicle because the signal that normally locks the car has been blocked by the device of the criminal.

They also make use of devices that amplify signals from the key fob to unlock vehicles. They may even do this when the key is inside the pocket of the driver or hanging from a hook inside the house. When the car is unlocked, they can use an ordinary diagnostic port or computer hackers to program an unlocked key fob to gain control over the vehicle.

Car manufacturers have come up with a range of anti-theft systems to protect against these types of attacks. However, criminals are constantly trying to beat these measures.

For example, they've started using devices that transmit on the same frequency as remote key fobs to intercept their signals. The thieves copy the unlock code of the key fob and start the vehicle using this fake signal.

This method is especially popular in the US in which many vehicles are equipped with wireless technology. Owners can unlock and start their vehicle using a mobile application on their phone. This technology is likely to gain popularity as more and more companies attempt to connect their vehicles with their owner's smartphones.

It is important that drivers follow the best practices to park their cars. They should not leave the key fobs in ignition and should always secure the car when not in it. If possible it is also recommended to use a steering or gearstick locking device. They should also consider having a tracking device fitted to their vehicle in the event that it's stolen car keys replacement.

Flat Battery

This kind of attack is more prevalent than many people believe. Thieves make use of inexpensive devices to extend the signal from your key fob to unlock and begin a car even when it's turned off. They then simply drive the car around the corner or even to a trailer and then drive off with it. It is possible to protect your vehicle from this by installing a starter circuit interrupt switch. Simpler versions come with an ON/OFF button which interrupts the circuit. It's priced at around $15 and is easy enough to put in yourself.

Car thieves are always trying new ways to gain access to vehicles and take them away. Car manufacturers, police and insurance companies are always trying to keep up with the latest methods and offer better anti-theft systems for modern vehicles. However, this does not stop thieves who are able to adapt quickly and find ways to bypass the most recent anti-theft measures.

Many thieves jam the signal with devices that use the same radio frequency as the fob. They place the device in their pocket or close to their vehicle, and it prevents the fob's lock commands from reaching the vehicle which leaves the vehicle unlocked. This can be done in just a few seconds. The device is inexpensive and can be purchased on the internet.

Hacking the computer system of the car is another option. This is more difficult, but still feasible. All cars have an diagnostic port and hackers have designed devices that plug into them and let them access the software of the car key stolen from house. They can then program a blank fob to work. It is possible to do this with older cars as well however it is more difficult without removing the ignition.

As more vehicles are linked to drivers' phones and this method could become more popular too. Once a criminal has the username and password for the vehicle app, they can then open the car or get it started using the app on their phone. You can guard yourself by not leaving valuables inside your car, and also by parking in garages.
