There are many security flaws that criminals/hackers can use to attack your vehicle, these include key jamming to phone phishing for car access. 

There has been a huge resurgence of vehicle crimes after a bit of a decline. Because of the increase in technology, there is now far more opportunity for hackers. The use of up to date security systems has also increased too.

Hacking methods

The most common method used by hackers is attacking keyless access. Thieves use a relay system to access vehicles by amplifying a signal from the key or fob inside the owners premises so it reaches the car or van outside.

This method can be thwarted by leaving the key inside a microwave or a Faraday cage to block the signal.

Additional security weak spots include:

• Phone phishing – Criminals can email you links that then connect to a car’s WiFi features, if it has them, and take control.
• Local remote control apps – There are tracking apps on the market that allows users to locate, start and control their cars from their phones. While these can be handy for those with Internet-connected cars, they also open the users up to hackers who have proved they can manipulate the system to locate, unlock and even cut out the engine of nearby cars on the system remotely.
• Tyre pressure monitor systems – Thieves use sensors inside the tyres of the vehicles to display false tyre pressure readings – and track the car.

Vehicle manufacturers are adding more and more technology, meaning that before you make a purchase you should carry out plenty of research on the vehicle and its capabilities and limitations and getting to know a vehicle you already own to make sure you’re aware of any potential security flaws.

Car hacking is relatively new and unkown threat, but it's real. Even though there are many up to date car security systems available, a steering lock may be an old fashioned method of protecting a vehicle, but it definitely does the job.
