Cars Being Stolen With Keyless Entry
Car owners who throw keys on tables or near their front door may be unwittingly permitting thieves to steal the signal. This relay attack is a sophisticated method used by criminals to steal keys from new vehicles.
All keyless ignition vehicles emit a low-power radio signal that is used to locate the fob that matches. If the signal is captured and recreated, it could be used to unlock the car and begin it up.
Relay Attack
Imagine your car being parked safely in the driveway, and the key fob tucked away in your home. You're sure that your car is safe, but unnoticed by you, sophisticated thieves are plotting an heist. Instead of slamming windows and jiggling locks, they are leveraging technology to hack into cars via digital chinks in their armor. This method of stealing cars with keyless access is called relay theft.
Cars with keyless entry are designed to function using a signal sent by the car's remote control (RF) transmitter to the owner's key fob. To stop keyless entry by unauthorised persons the RF transmitters that are on the key fob as well as the car are programmed only to turn on when they are within a certain distance from one another. However, thieves are able to override this restriction using an attack known as the'relay attack'.
Two people are required to complete this: one person stands close to the car and utilizes a device to capture an electronic version of the the key fob. The other, who is at the house of the owner, uses a second device to transmit the key fob signal back to the car. This trick tricks the car into thinking that the key fob is near enough to be able to unlock it and begin the engine.
In the past, this kind of attack required expensive equipment to perform. It is now possible to purchase an inexpensive relay transmitter on the internet and complete a heist within minutes. This is why it's so popular among car thieves.
All modern vehicles with keyless access are at risk. Certain cars are more susceptible to this kind of attack than others. Researchers have examined 237 well-known cars and found that all of them are susceptible to being stolen using this method.
Tesla vehicles are supposedly less prone to this kind of theft, but Tesla hasn't yet implemented UWB features that could effectively perform distance checks on the car's signal to prevent relay attacks. The company has said it will do so in the future, but for now they are vulnerable. This is why it's crucial to adopt a proactive approach to your security in your car and install an anti-theft kit that safeguards your keys and vehicle from these kinds of attacks.
CAN Injection Attack
Modern vehicles are designed to protect themselves from theft by exchanging cryptographic messages with the key to prove it's genuine. The system is generally believed to be secure, however criminals have found a way to circumvent it. They impersonate a smart key, transmit messages to the vehicle, and then drive off. To do that they gain access to the smart key's internal communication network.
Today, most automobiles are equipped with between 20 and 200 electronic control units (or ECUs) that manage different aspects of the car's operation. They communicate with one another using a network known as CAN bus. These ECUs enter a low-power sleep mode to reduce their power consumption. This mode is activated when the ECUs receive a "wake up" frame. These frames typically come via the door or smart key receiver ECU. However, these messages aren't always authenticated or encrypted, which means that they can be intercepted by criminals with a cheap and simple device.
To accomplish this, they search for a location where they can directly connect to the CAN bus wires. These are often hidden away in the headlights or 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 known as an CAN injection attacker to send out fake messages that trick the car's security systems into unlocking it and disengaging the engine immobilizer.
These devices are for sale 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 address the issue in their current models, but the reality is that thieves will continue to steal whatever they can get their hands on. We can stop this from happening by implementing mechanical safety measures like Discloks in every car we own and parking them in well-lit and visible areas.
Jamming the Signal
In a variant different to the relay attack, thieves may make use of a device to block the signal from a key fob when the vehicle is locked. The device could be hidden in the pocket or hiding place of a thief on a parking lot, or even near the driveway being targeted. Once owners press the lock button on their fobs and walk away and leave, they don't have to think about whether or not the car actually locks. Instead, thieves are able to escape with the vehicle since the signal that normally locks the car is blocked by the crook's device.
The crooks also use devices to amplify the signal from the key fob to unlock vehicles. They can accomplish this if the key is in the driver's pocket or hanging from a hook in the home. Once the car has been unlocked, hackers can use an ordinary diagnosis port to program an unlocked fob.
To safeguard against this kind of attack, car manufacturers have developed a variety of anti-theft gadgets. But, as always, thieves find ways to defeat these measures.
They've been using devices that transmit at the same frequency as remote keyfobs in order to intercept signals. The thieves can then copy the unlock code of the key fob and then start the car with this fake signal.
This method is very popular in the US and Europe where many automobiles are equipped with wireless technology that allows owners to unlock and start their vehicle using a mobile app on their phone. This technique is likely to become more popular as more companies attempt to link their cars with their owners phones.
In addition to implementing anti-theft systems in vehicles, it's important for drivers to leverage best practices when they park their vehicles. It is not a good idea to leave keys in the ignition. They should always ensure that their vehicle is locked completely when they're not in it and should use a steering wheel or gearstick lock, if it is possible. They should also consider having a tracking device fitted to their car in the event it gets stolen.
Flat Battery
This type of attack occurs more often than we think. The thieves employ low-cost devices that increase the signal of your key fob to enable it to unlock and start your car if it is off. Then, they drive the car to the trailer or around a corner to take the vehicle away. It would be 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 about $15 and is simple to install.
Car thieves are always looking for new ways to get into vehicles and steal them. The police as well as the car makers and insurance companies are always trying to keep up to their tactics and offer better anti-theft solutions for the latest cars. However, this isn't stopping thieves who easily adapt and find ways to bypass the latest anti theft measures.
Many thieves block the signal with devices that operate on the same radio frequency as the fob. They place the device in their pocket or close to their vehicle, and it blocks the fob's lock commands from reaching the car and thereby leaving the vehicle unlocked. This can be done in just a few seconds. The device is affordable and can be purchased on the internet.
Hacking the computer system of the car is an alternative option. This is more difficult, but nevertheless possible. All cars have an diagnostic port and hackers have created devices that plug into them and allow them access the software of the car. They can then program the fob with blank code click here to work. It is also possible to do this on older vehicles, however it is more difficult to do so without removal of the ignition lock.
As more vehicles are connected to the phones of drivers the method is likely to be more popular. Once a criminal has the username and password for an app for vehicles they are able to unlock the car or start it using the app on their phone. You can safeguard yourself by not leaving valuables inside your car, and also by parking in garages.
