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.
