Cars Being Stolen With Keyless Entry
Car owners who throw keys on tables or near their front doors may be unwittingly permitting thieves to steal the signal. This relay attack is a highly-tech method used by criminals to steal keys from new vehicles.
All keyless ignition cars emit an low-power radio signal that is in search of a fob to respond. If the signal is recorded and recreated, it can be used to unlock the car and 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 not seen by you sophisticated thieves are planning an heist. Instead of breaking windows or jimmying locks, thieves are leveraging technology to gain access to cars through digital cracks in their armor. Also known as relay theft, it's an increasingly popular method of stealing cars that have keyless entry.
Cars with keyless entry are designed to operate via an electronic signal that is transmitted by the car's remote control (RF) transmitter to the owner's key fob. To stop unauthorized keyless entry the RF transmitters on the key fob as well as in the car are programmed to only be activated when they're within certain distance from each other. A thief, however, can circumvent this limitation employing a technique called the "relay-attack".
Two people are required to do this: one stands close to the car and uses a device that captures a digitalized version of the signal from the key fob. The other person who is at the owner's home, uses a second gadget to transmit the signal from the key fob back to the car. This trick tricks the car into thinking that the key fob is near enough to allow it to unlock and start it up.
In the past, this kind of heist required expensive equipment in order to execute. Today, you can purchase an inexpensive relay transmitter online and pull off an heist in just a few minutes. This is why car thieves are enthralled by it.
All modern cars with keys are at risk. Certain cars are more susceptible to this kind of attack than others. In fact researchers have examined 237 popular vehicles and found that they could be all stolen using this method.
Tesla vehicles are supposedly less prone to this kind of theft, but the company hasn't yet implemented UWB features that would effectively conduct distance checks on the car's signal and prevent relay attacks. The company has said it will do so in the future, but until then they are still vulnerable. Installing an anti-theft device that protects both your car and your keys against such a threat is a proactive way to ensure your car's security.
CAN Injection Attack
Modern vehicles are designed to protect themselves from thieves by transferring cryptographic messages using the key to prove it's genuine. This system is generally reckoned to be secure, but criminals have found a way to circumvent it. They just impersonate the smart key, and send other messages to the vehicle letting it unlock the doors, turn off its engine immobilizer, and then go on their way. To do that they gain access to the smart key's internal communications network.
The majority of cars today are fitted with between 20 and over 200 electronic control units, also known as ECUs, that manage various aspects of the vehicle's operation. They communicate with each other via a network known as CAN bus. To reduce power consumption they ECUs are put into sleep mode with low power that is activated when they receive a 'wake up frame. These frames are typically sent by the ECU that manages the smart key or door. However they aren't always encrypted or authenticated so they can be intercepted by criminals who have a low-cost and basic device.
To do this, they look for a spot where they can directly connect to the CAN bus wires. They're usually hidden inside the headlights or elsewhere in front of the vehicle, and are accessible by pulling the bumper and cutting holes in the headlamp assembly to expose them. The thieves employ the device referred to as an CAN injection attack. It is used to send out fake messages that trick the car's safety systems to unlock and disable the engine immobilizer.
The devices are available on the Dark Web and work with most 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 manufacturers fix it in their existing models, but the reality is that the thieves will continue to steal everything they can lay their hands on. The best we can do is to make an effort to prevent this from happening by putting in mechanical security measures such as Discloks on all of our vehicles, and making sure that they are parked in well-lit areas that are clearly visible to people passing by.
Jamming the Signal
In a variant of the relay attack that employs a device that can be used to block the signal transmitted by the key fob when the car is locked. The device could be in the pocket or hiding place of a thief on a parking lot, or even near the driveway being targeted. Once the owners hit the button to lock their fobs and leave, they don't think about whether or not their car is actually locks. The device of the crook blocks the signal that locks the vehicle. Therefore, thieves can escape with the car.
The crooks also here make use of 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 driver's pocket or hanging from a hook in the home. After the car is locked, hackers can use a standard diagnosis port to create an unlocked fob.
Automobile manufacturers have developed a variety of anti-theft solutions to guard against these kinds of attacks. However, thieves will always 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 crooks then copy the unlock code from the key fob and start the vehicle with this fake signal.
This method is very popular in the US and Europe where many cars are equipped with wireless technology that allows owners to unlock and start their vehicles by using a mobile application on their smartphone. This technique is likely to increase in popularity as more car manufacturers attempt to connect their cars to their owners phones.
It is crucial that drivers use best practices to park their cars. They should not leave their keys in the ignition and should always lock the car when they are not in it. If possible, they should also use a gearstick lock or steering device. It is also recommended to think about fitting a tracking device to their vehicle in the event that it's stolen.
Flat Battery
This kind of attack happens more often than most people realize. Thieves use cheap devices to extend the signal from your key fob to unlock and start cars even if they're switched off. Then they drive the vehicle to an unmarked trailer or around a corner to take the car away. It is possible to protect your car from this by installing an interrupter switch for the starter circuit. Simpler versions include an ON/OFF button that interrupts the circuit. It's priced at around $15 and is simple enough to install by yourself.
Car thieves are always working on new ways to gain access to vehicles and steal them. The police as well as the car makers and insurance companies are constantly trying to catch up to their tactics and develop better anti-theft systems for modern vehicles. But this doesn't stop thieves who can adapt quickly and find ways around the most recent anti-theft measures.
For instance, many criminals employ devices that operate on the same frequency as the fob in order to block the signal. They place the device in their pocket or close to their vehicle, and it blocks the fob's lock command from reaching the car and thereby leaving it unlocked. This can be done in just a few seconds. The device is cheap and can be purchased on the internet.
Hacking the computer system of the car is another option. This is more difficult, but it is still possible. All cars have an diagnostic port and hackers have created devices that plug into them and let them access the car's software. From there, they can program the blank key fob to get it to work. It is also possible to do this on older vehicles, however it is more difficult to do so without taking off the ignition lock.
This method could be more popular if more vehicles are connected to drivers' mobile phones. Once a criminal has access to the username and password to an application for vehicles they can open or start the vehicle by using the app. You can help be safe from these kinds of attacks by not leaving valuables in your car and putting it in a garage or secure parking lot.
