Modern vehicles have become prime targets for cybercriminals. Security researchers demonstrated 76 separate vulnerabilities across multiple manufacturers at a major hacking competition last month, a clear reminder that the convenience of connected cars comes with risks most drivers don’t fully understand.
The Pwn2Own Automotive 2026 competition in Tokyo exposed weaknesses in everything from infotainment systems to EV chargers. Researchers earned more than $1 million after exploiting zero-day vulnerabilities, which are security flaws unknown to manufacturers at the time of discovery. Tesla alone accounted for 37 vulnerabilities, including one exploit that gained full root access through a USB attack.
These are not theoretical risks. A compromised system can allow attackers to steal personal data, track a vehicle’s location, or potentially manipulate vehicle functions. The 2015 incident in which researchers remotely disabled a Jeep Cherokee demonstrated this was possible. Today’s vehicles are far more connected, and therefore far more exposed.
Key Takeaways
Connected vehicles dramatically expand the potential attack surface.
Researchers continue to find real, exploitable vulnerabilities across major brands.
Most real-world theft now combines digital and physical attack methods.
Automakers are investing heavily in cybersecurity but remain in a reactive posture.
Basic owner precautions still prevent many common attacks.
🎧 Listen: 60-Second Summary
The Money Flooding Into Automotive Security
The automotive cybersecurity market reached $3.37 billion in 2024 and is projected to grow to $12.6 billion by 2032. That rapid growth reflects how seriously the industry now views cyber risk.
Spending is focused largely on embedded security systems such as:
Hardware Security Modules that encrypt communications
Secure boot systems that verify software integrity
Over-the-air updates used to patch vulnerabilities remotely
These tools are essential because modern vehicles contain dozens of electronic control units managing everything from braking to door locks. Each connected feature adds another possible entry point.
The industry is investing heavily, but much of that investment is catching up to risks created over the last decade.
How Hackers Actually Get In
High-profile demonstrations often focus on wireless exploits, but physical access remains one of the most common real-world attack paths.
Law enforcement agencies report growing use of CAN bus injection attacks. Thieves access wiring through headlights or taillights, connect a small device, and trick the vehicle into believing a valid key is present. The process can take only minutes.
Key fob relay attacks are also widespread. Criminals capture a wireless signal from inside a home and relay it to the parked vehicle, unlocking it without ever stealing the key.
Smartphone apps introduce another vulnerability. A compromised phone can provide access to remote vehicle controls and stored personal data. Telematics systems used for insurance or fleet tracking create similar exposure.
The Disclosure Problem
Only 59 percent of automakers maintain formal vulnerability disclosure programs where researchers can safely report flaws.
Some manufacturers actively engage with researchers. Others publish little or no vulnerability information, making it difficult to judge whether systems are highly secure or simply under-tested.
Security experts note that transparency often signals stronger security practices, not weaker ones.
What Drivers Can Do Now
For most owners, the biggest threat is still keyless-entry theft rather than sophisticated hacking.
Practical steps include:
Store key fobs in signal-blocking pouches or metal containers
Install vehicle software updates promptly
Avoid plugging unknown devices into the OBD-II port
Review app permissions tied to the vehicle
Use visible deterrents such as steering wheel locks
Many vehicle thefts remain opportunistic. Making a car harder to access often pushes criminals elsewhere.
The Industry’s Next Moves
Manufacturers are deploying stronger encryption, network monitoring, and secure software validation processes. Compliance frameworks like ISO 27001 and TISAX are becoming standard.
However, live exploitation testing continues to reveal vulnerabilities that internal audits miss. As vehicles add driver-assistance systems, vehicle-to-everything communication, and cloud integration, the attack surface continues to grow faster than security solutions.
What This Means for Vehicle Buyers
Connected features deliver real value, but cybersecurity has become a permanent consideration alongside reliability and safety.
Buyers should evaluate whether manufacturers:
Provide ongoing software updates
Maintain security disclosure programs
Demonstrate active vulnerability management
The shift to connected vehicles is irreversible. Understanding the risks helps drivers reduce exposure while still benefiting from the technology.
Frequently Asked Questions
Are hackers really targeting everyday vehicles?
Yes. Researchers continue to find exploitable weaknesses in common vehicle systems such as infotainment, wireless key access, and internal vehicle networks. Many real-world attacks focus on theft rather than remote control scenarios.
What is the most common car hacking method today?
Key fob relay attacks and CAN bus injection are currently among the most frequently reported methods. These techniques allow thieves to unlock or start vehicles without needing the original key.
Do hackers need physical access to the car?
Not always. Some attacks can be carried out wirelessly. However, many real-world theft methods involve brief physical access to wiring or external components to inject signals into the vehicle’s network.
Why are connected cars more vulnerable?
Modern vehicles include dozens of electronic control units, wireless connections, mobile apps, and cloud services. Each added feature creates another potential entry point that must be secured.
Are automakers doing anything to fix these issues?
Yes. Manufacturers are investing heavily in embedded security, encrypted communications, intrusion detection systems, and over-the-air software updates to patch vulnerabilities after vehicles are sold.
How can drivers reduce their risk?
Simple steps make a big difference. Store key fobs in signal-blocking cases, install software updates promptly, avoid plugging unknown devices into the OBD-II port, and review which apps have access to the vehicle.
Does a vehicle with connected features mean it is unsafe?
Not necessarily. Connected features provide real benefits, but they require stronger cybersecurity awareness. Risk can be managed through updates, manufacturer support, and basic protective habits.
