Why Cybersecurity Matters to the EV Ecosystem

EVs have emerged as a promising solution to address climate issues, create new job opportunities, and act as an engine for economic growth. However, the increasing connectivity of EVs creates new cybersecurity risks. The recent combination of cutting-edge technologies and mobility in EVs brings new cybersecurity vulnerabilities to ensure safety, reliability, and trustworthiness.

This article talks about EV cybersecurity in India, and examines possible next steps. Specifically, it answers:

1. What major cybersecurity risks do EV ecosystems face?
2. Why is it important to address cybersecurity in the EV ecosystem, and how does it impact stakeholders, including EV manufacturers, charging infrastructure providers, and policymakers?
3. How can stakeholders mitigate these cybersecurity risks and enhance the resilience of the EV ecosystem?

Assessing Current Cybersecurity Processes

In EVs, each individual component is connected to a central operating system. This operating system ensures smooth communication between all of the components, as well as monitoring their individual health and performance. Although this model is efficient, it also means that hackers can use the operating system as a single point of attack to bring down the entire EV. To highlight this vulnerability, a research student hacked into 25 Tesla EV cars using a third-party tool called Teslamate.

Charging infrastructure introduces additional risks. By connecting to a charger, which is necessary for monitoring charge levels and avoiding voltage fluctuations, EV operating systems become vulnerable to malware and ransomware that can be transmitted through the charger. Malware can also be transmitted in the other direction: from the infected EV to the charger, and then from the charger to the power grid. Ransomware, on the other hand, is more dangerous because cybercriminals lock the EV users' personal data using encryption techniques and demand a high payment as ransom to provide the decryption key. Such attacks have the potential to cause large-scale power outages, similar to the Colonial Pipeline ransomware attack that inflicted fuel shortages on the United States’ east coast in 2021.

EVs are also susceptible to social engineering attacks such as phishing. One investigation discovered that scammers in India had defrauded would-be EV customers of approximately $1,000,000, by using Google Ads to misdirect them to phishing sites and charging them for down payments or booking fees for nonexistent EVs.

Although these incidents are relatively rare so far, growing EV adoption of EVs opens the door to more frequent and serious security breaches with widespread ramifications.

The Value Chain of the Indian EV Ecosystem

Cybersecurity risks can potentially discourage EV adoption, and reverse the environmental and economic gains that EVs have achieved so far. To counteract this, EV manufacturers, charging station operators, and service providers must work to earn consumers’ trust. Otherwise, they may incur reputational damage, massive financial losses, and even legal liabilities. Stakeholders who are not directly connected to EVs must also step in; cyberattacks on EVs could lead to public safety hazards such as grid blackouts, disabled EV charging infrastructure, mass malware, stolen personal information, and more.

To mitigate these risks, protect individuals and companies in the EV ecosystem, and safeguard national resources including power grids, cybersecurity for EVs is a top priority today. The first step to building a comprehensive cybersecurity solution is to understand the most likely threats to both charging networks and EVs themselves.

Major Cybersecurity Risks in EVs

EVs’ inherent architecture and design make them vulnerable to unique cybersecurity threats such as the unauthorized takeover of vehicles. Furthermore, EVs’ reliance on software puts them at risk of malware attacks and data breaches.

Hacking and Unauthorized Access to Vehicles

Most EVs unlock via either apps or RFID chips. Unfortunately, car manufacturers’ apps are demonstrably vulnerable to hacking, and RFID chips are easy to clone. This gives hackers two different mechanisms for easily gaining unauthorized access to an EV's systems. In addition to physically unlocking the EV, they could remotely manipulate braking, acceleration, or steering functionality, potentially leading to life-threatening accidents.

Data Breaches and Privacy Concerns

EVs and their associated charging infrastructure collect and store a wealth of data, including user profiles, location data, and payment details. Cybercriminals can exploit this valuable information through wireless technology and malicious software for financial gain. This risk can hinder EV adoption by exacerbating existing public concerns about data safety, usage, and sharing.

Malware and Software Vulnerabilities

Malware can infect EVs, compromising their functionality, safety features, and data integrity. Potential consequences of these attacks range from inconvenience and financial losses to threats to public safety. Since EV components are so closely connected to other systems, hackers can inflict virtually unlimited damage.

Besides EVs, the charging networks can also be impacted by cyberattacks.

Major Cybersecurity Risks in the EV Charging Networks

The Electric Vehicle Supply Equipment (EVSE) industry is experiencing explosive growth due to the increasing demand for EV charging points. Unfortunately, due to their unique position at the intersection of the energy and transportation sectors, EVSEs are highly susceptible to cyberattacks. From cyberattackers’ perspective, EVSEs provide a perfect opportunity to cause widespread damage.

Below are some potential ways for hackers to attack EV charging networks.

Disrupting Electrical Grids

Since chargers connect to national resources like power grids, cyberattackers have the opportunity to cause major disruptions. Electrical grids are an unusually easy and attractive target for cybercriminals, since attacking them can inflict extensive damage with little effort.

Disabling EV Charging Infrastructure

Hackers can disable EV charging stations, thereby stranding drivers. The magnitude of the threat increases with every new charging station. For example, the United States’ current governmental plan to fund EV charging stations across 53,000 miles of highways will give hackers myriad opportunities to disrupt operations.

Accessing Interconnected Systems

The EVSE architecture encompasses a variety of components and architecture types. For example, some EVSE equipment may use renewable energy resources, or may be connected to building management systems. This interconnected architecture means that, by gaining access to a single charger, hackers can attack an entire system.

All of these threats require comprehensive solutions, both to protect public safety, and to build confidence and trust among potential EV owners.

Addressing Key Cybersecurity Challenges in the EV Ecosystem

Overcoming the above cybersecurity challenges requires a proactive and multifaceted approach from all stakeholders. Given the dynamic nature of cyber threats, the complexities in implementing solutions, and the lack of awareness about the underlying problem, collaboration is crucial now.
