      From USB Port to Root Shell: The Tesla TCU Vulnerability that Exposed Cars to Physical Tampering     By CyberDudeBivash • October 01, 2025, 11:12 AM IST • Automotive & IoT Security Analysis   A modern vehicle is a datacenter on wheels, and no company exemplifies this more than Tesla. But with this technological leap comes a new and complex attack surface. Security researchers have recently detailed a significant vulnerability in the Telematics Control Unit (TCU) of certain Tesla vehicles, demonstrating how physical access to an internal USB port can be leveraged to gain a full `root` shell. This is not a remote attack that can be done from across the internet, but it represents a serious flaw in the physical security of the car's most critical communication system. This deep dive will explore how the attack works, what it means for owners, and the broader lessons for the future of **automotive cybersecurity**.   Disclosure: This ...
