A team of European ethical hackers, PCA Cyber Security (formerly PCAutomotive), successfully took full control of a 2020 Nissan LEAF using inexpensive components sourced from eBay and a junkyard. By exploiting multiple security vulnerabilities, they demonstrated:
- Real-time GPS tracking
- Eavesdropping via the car’s microphone
- Playing audio through the speakers
- Steering wheel manipulation while driving
The full research was presented at Black Hat Asia 2025, exposing critical flaws:
🔹 Anti-theft system bypass (CVE-2025-32056)
🔹 Man-in-the-Middle attack on the update app (CVE-2025-32057)
🔹 Memory overflow leading to remote code execution
🔹 Lack of software signature verification
🔹 Faulty CAN bus filtering
🔹 Persistent Wi-Fi connections as attack vectors
The hackers could not control brakes or acceleration, but they displayed “Hacked by PCAutomotive” on the dashboard.

You Should Know: How to Test and Secure Connected Vehicles
1. CAN Bus Analysis & Exploitation
Modern vehicles rely on CAN (Controller Area Network) buses for communication. Attackers inject malicious CAN frames to manipulate vehicle functions.
Tools & Commands:
Install CAN utilities on Linux sudo apt install can-utils Monitor CAN traffic candump can0 Inject CAN frames (example: unlock doors) cansend can0 123DEADBEEF
2. Reverse Engineering Firmware
Extracting firmware from ECUs (Electronic Control Units) helps find vulnerabilities.
Steps:
1. Dump firmware via OBD-II port:
sudo apt install openobd openobd-cli --dump-firmware --output firmware.bin
2. Analyze with Ghidra:
ghidra firmware.bin
3. Exploiting Wi-Fi & Bluetooth
Many vehicles use weak Wi-Fi/Bluetooth authentication.
Kali Linux Commands:
Scan for vehicle Wi-Fi sudo iwlist wlan0 scan Crack WPA2 key (if weak) aircrack-ng -w rockyou.txt capture.cap
4. Preventing Remote Hacks
- Disable unused services (Wi-Fi, Bluetooth when parked).
- Update vehicle software regularly.
- Use a Faraday pouch to block key fob signals.
What Undercode Say
This attack highlights critical IoT security flaws in modern vehicles. Manufacturers must enforce:
– Strong CAN bus filtering
– Secure OTA (Over-the-Air) updates
– Hardened Wi-Fi/Bluetooth stacks
Expected Output: A detailed penetration testing report with exploitable CAN commands and mitigation steps.
Prediction
As connected cars evolve, expect more ransomware attacks locking vehicles until payment. Automotive cybersecurity will become a billion-dollar industry by 2030.
Expected Output: Increased demand for ethical hackers specializing in vehicle security.
Relevant Commands for Further Testing:
Simulate CAN attacks with SocketCAN sudo ip link set can0 up type can bitrate 500000 canplayer -I can_logfile.log Detect ECU vulnerabilities with Metasploit msfconsole use auxiliary/scanner/automotive/can_bus
Conclusion: Always audit your vehicle’s digital systems before attackers do.
Expected Output: A secure, patched vehicle resistant to remote hijacking.
