Cybersecurity Risks in the Electric Vehicle Revolution: Navigating the Threats of a Connected Future

Electric vehicles (EVs) have been making waves in the automotive industry as a promising solution for a greener future. With the increased demand for sustainable transportation, EVs offer a cleaner alternative to traditional petrol-diesel powered(gasoline) vehicles. However, with the rise of EVs comes a new concern – cybersecurity risks.

The vast computing power and numerous online connections that come with EVs make them a prime target for cyberattacks. According to experts, an electric vehicle could have up to 3,000 electronic control units, compared to a high-end standard internal combustion luxury car that might have only 150. This increased number of electronic components in EVs means that there is a higher potential for cyberattacks.

Cybersecurity risks in EVs pose a threat not only to the vehicle itself, but also to the driver, passengers, and other vehicles on the road. If a hacker were to gain access to an EV, they could cause a range of problems, from locking people out of their cars to damaging the charging system. In the worst-case scenario, they could even cause the batteries to overheat or control the steering, braking, or acceleration.

As the EV industry continues to grow, it’s important to address the potential cybersecurity risks associated with these vehicles. In this article, we’ll explore the different ways that EVs can be vulnerable to cyberattacks and what measures are being taken to protect them.

Potential Scenarios of a Cyberattack on an EV

If a hacker were to gain access to an electric vehicle, the potential consequences could range from inconvenient to potentially dangerous. In this section, we’ll discuss the different scenarios that could occur if a hacker were to target an EV.

One of the most common scenarios is a ransomware attack. This type of attack occurs when a hacker locks the owner out of their vehicle until they receive payment in exchange for unlocking it. This type of attack could leave an EV owner stranded and unable to start their vehicle.

Cybersecurity Risks

Another potential scenario is damage to the charging system. The charging of an EV is controlled by software and chips, and if a hacker were to gain access to this system, they could potentially cause damage to the vehicle.

Additionally, the transmission of power from the batteries to the electric motors is also controlled by chips, and if this were to be compromised, it could cause issues with the vehicle’s performance.


ScenarioDescription
Ransomware AttackA hacker gains access to a vehicle’s systems and locks the owner out, forcing them to pay a ransom to regain access to their car.
Damage to the Charging SystemA hacker takes control of the charging system, potentially causing damage to the vehicle or the charging equipment.
Overheating BatteriesA hacker causes the batteries in the vehicle to overcharge and potentially heat up, leading to a dangerous situation.
Control of Steering, Braking, or AccelerationA hacker gains control of the vehicle’s steering, braking, or acceleration, putting the safety of the passengers and others on the road at risk.
Potential Scenarios of a Cyberattack on an EV

One of the worst-case scenarios is overheating batteries. An EV’s batteries are controlled by software and chips, and if a hacker were to cause them to overcharge, they could potentially heat up and cause a fire. This could be a dangerous situation for both the vehicle and anyone in the vicinity.

Finally, a hacker could also potentially control the steering, braking, or acceleration of an EV. These critical components of a vehicle are controlled by computers, and if a hacker were to gain access to these systems, they could cause the vehicle to behave erratically or even put the driver and passengers in danger.

Vulnerable Communication Pathways in EVs

One of the biggest challenges in protecting EVs from cyberattacks is the numerous communication pathways that they use. Hackers can exploit these pathways to gain access to a vehicle’s systems and cause a range of problems.

EVs typically communicate with the car company that made them, the dealership, and the supplier of the charging station. When an EV is plugged in, it also connects with the electric utility behind the charging station. These communication pathways provide potential entry points for hackers to exploit.

Another risk is the potential for one hacked car to spread the issue to other vehicles through a charging station. If a hacker were to infect one car with a certain type of software, it could be transmitted to the charger itself when the car is plugged in.

From there, the software could potentially propagate itself to the entire charging network through the computers that run public charging stations.

Finally, there is also the potential for hackers to distribute dangerous software to a large number of vehicles through electronic updates sent by car makers.

Car makers often send updates to their EVs wirelessly, and if a hacker were to gain access to this process, they could potentially distribute malware to hundreds, thousands, or even millions of vehicles.

Government and Industry Response to the Threat of Cyberattacks on EVs

As the threat of cyberattacks on EVs becomes more prevalent, the government and industry are taking steps to address the issue and protect these vehicles from potential attacks.

In October of last year, the Biden White House gathered a group of executives from the EV industry to discuss the need for greater security.

Additionally, the National Highway Traffic Safety Administration released new guidelines for EV manufacturers, one of which stated that crucial components such as acceleration, braking, and steering should not be connected to anything wireless.

Despite these efforts, there have not been many new laws passed that would mandate cybersecurity controls in the EV industry. This means that it’s up to the industry and EV owners to take steps to protect themselves from potential cyberattacks.

For EV owners, the best way to stay safe is to be aware of the possibility of hacking and to be vigilant for any signs of erratic behavior in their vehicle. If your vehicle were ever to act erratically, it’s important to stop and have it looked at by a professional, rather than assuming it’s just a small glitch.


The government and industry are taking steps to address the threat of cyberattacks on EVs, but it’s important for EV owners to be proactive in protecting their vehicles from potential attacks.

By being aware of the risks and taking steps to stay safe, EV owners can help ensure that their vehicles remain secure from potential cyberattacks.
