Security experts spent two years analyzing the Nissan Leaf, uncovering nine critical vulnerabilities that allow attackers to remotely control the vehicle. These flaws enable unauthorized steering, unlocking doors, and accessing trip data—all over the internet without physical access. The vulnerabilities have remained unpatched since 2023, posing serious risks to drivers.
Researchers Radu Motspan, Mikhail Evdokimov, and Polina Smirnova presented their findings at Black Hat Asia, detailing the attack chain in a 118-slide deck. The exploitation involves:
1. Bluetooth Intrusion: A single crafted frame bypasses security.
2. Persistence Attack: Malware survives factory resets.
- CAN Bus Exploitation: Attackers manipulate firmware, door locks, and air conditioning.

You Should Know: Critical Commands & Countermeasures
Bluetooth Exploitation (Step 1)
Attackers use crafted Bluetooth Low Energy (BLE) packets to gain initial access.
Scanning for vulnerable BLE devices sudo hcitool lescan Injecting malicious BLE frames sudo gatttool -b <MAC_ADDRESS> --interactive
Maintaining Persistence (Step 2)
Malware is embedded in non-volatile memory, surviving resets.
Checking for rogue processes (Linux) ps aux | grep -i "malicious_process" Forensic analysis of persistent storage dd if=/dev/mmcblk0 | strings | grep -i "backdoor"
CAN Bus Attacks (Step 3)
The Controller Area Network (CAN) bus allows lateral movement.

What Undercode Say
This research highlights the dangers of IoT in vehicles—smart cars are essentially unpatched computers on wheels. Key takeaways:
– Patch Management: Unlike PCs, cars rarely receive timely updates.
– Bluetooth Hardening: Disable BLE when not in use.
– CAN Bus Security: Implement CAN message authentication.
Expected Output: A fully documented attack path with mitigations for automotive cybersecurity professionals.
