Israel-based startup Karamba Security has announced it has come out of stealth with a $2.5 million finance round in its attempts to provide a “unique approach to in-car security.”

Karamba Security's purpose-built ECU endpoint solution protects the externally connected components of a car, identifying attempts to attack and block exploits from infiltrating the network of the car.

The new solution will enable automakers to embed security enforcement and detection capabilities directly on the ECU, ensuring that only permitted code and applications are loaded and run on the controller. The solution blocks all foreign code, keeping the control safe from attacks via USB port, service port, internet or other channels.

The FBI warning against cybersecurity risks has raised concerns over the safety of connected cars. Attackers have been able to get into and take control of car systems, even killing the care engine while driving on a freeway. Karamba Security's solution hardens the car's electronic control units, which are open to external access.

Ami Dotan, CEO of Karamba Security, said: "Customers have been very excited about our ECU endpoint approach. By stopping attacks at the ECU, attackers can’t make it inside the car’s network, which means the car’s ongoing operations are safe. Our early warning and malware prevention capabilities allow car companies to provide drivers smart vehicles that will get them where they want to go, safely."

Scott J. McCormick, President of the Connected Vehicle Trade Association (CVTA), said: "At CVTA we see a growing need for cybersecurity to ensure drivers' safety, as connected cars may become a target for hackers.

"Early detection of cyberattack attempts and prevention of malware without false positive risks are essential to immunise cars against malicious software. We are impressed with Karamba Security's unique approach, which can be used to provide early warnings of attack attempts and prevent malware from infiltrating the safety controllers of both new and existing cars."
