Cybersecurity is no longer limited to protecting computers, databases, or financial systems. As digital technologies become embedded into physical infrastructure, cyberattacks increasingly have the potential to affect real-world operations, public safety, and even human lives.
One of the most significant developments in recent years has been the emergence of connected vehicles. Modern automobiles, electric vehicles (EVs), and smart transportation systems rely extensively on software, cloud computing, wireless communication, sensors, and Internet of Things (IoT) technologies. These innovations have transformed vehicles into highly connected digital platforms capable of communicating with drivers, manufacturers, mobile applications, service providers, and surrounding infrastructure.
However, according to CA Mayur Joshi, cybersecurity researcher and digital threats expert, this connectivity has created a new category of cyber risk that is often underestimated by consumers, organizations, and policymakers.
As part of his Digital Threats Series, Mayur Joshi examines how cyberattacks have evolved from traditional data breaches into threats capable of disrupting critical infrastructure, healthcare systems, industrial operations, and transportation networks. Connected vehicles represent one of the most visible examples of this transformation.
The same technologies that make vehicles smarter, safer, and more efficient can also create opportunities for malicious actors to exploit vulnerabilities within connected ecosystems.

Can Cars Really Be Hacked?
One of the most frequently asked questions in automotive cybersecurity is whether hackers can actually gain access to a vehicle’s systems.
The answer is yes.
Security researchers have repeatedly demonstrated that vulnerabilities within connected vehicle systems can potentially be exploited under certain circumstances.
One of the most widely discussed examples occurred in 2015 when researchers successfully demonstrated a remote compromise of a Jeep Cherokee. During the controlled experiment, researchers were able to interact with several vehicle functions after exploiting vulnerabilities in the connected system.
The demonstration attracted global attention because it highlighted a reality that many consumers had not previously considered: modern vehicles contain software vulnerabilities just like computers and smartphones.
While the demonstration was conducted for research purposes, it fundamentally changed how the automotive industry approached cybersecurity.
According to Mayur Joshi, vehicle hacking represents a broader shift in cyber risk where digital attacks can potentially influence physical systems and create real-world consequences.

Every digital connection creates a potential attack surface.
As the number of connected components increases, so does the complexity of securing the entire ecosystem.
This challenge becomes even more significant as electric vehicles and autonomous vehicle technologies continue to expand globally.
Understanding Data Privacy Risks in Connected Cars
Connected vehicles collect significant amounts of information about drivers and passengers.
This information may include:
-
Location history
-
Driving behavior
-
Navigation destinations
-
Vehicle diagnostics
-
Contact information
-
Communication records
-
Mobile device integrations
If unauthorized parties gain access to this information, privacy risks emerge.
For individual users, this may result in surveillance, tracking, or misuse of personal information.
For organizations, compromised vehicle data could expose sensitive operational activities, executive movements, or business intelligence.
For governments and defense organizations, vehicle data may potentially reveal strategic locations, travel patterns, or critical infrastructure access points.
This is one reason why automotive cybersecurity is increasingly being discussed alongside national security and critical infrastructure protection.
How Vehicle Hacking Can Affect Physical Safety
One of the most important differences between automotive cybersecurity and traditional cybersecurity is the potential for physical consequences.
