Connected cars work by using software to control a range of vehicle functions. Tech Crunch found that connected vehicles have up to 125 different electronic control units (ECUs) designed to handle a range of diagnostic, navigation and entertainment systems.

With hundreds of ECUs in a single car, this translates into over 100 million lines of code. These lines of code act as “instructions” for your vehicle to dictate how features like steering, brakes, radio systems, lights and air conditioning units will function.

But for every 1,000 lines of code, experts say at least 10-15 mistakes will be discovered. These mistakes can often leave holes in a vehicle’s software (vulnerabilities) that fraudsters exploit and access for fraud, identity theft and other cybersecurity and identity crimes.
