The paper "Comprehensive Experimental Analyses of Automotive Attack Surfaces" by Stephen Checkoway et al. explores the security vulnerabilities of modern automobiles, focusing on their external attack surfaces. The authors systematically analyze various attack vectors, including mechanics tools, CD players, Bluetooth, and cellular radio, to demonstrate that remote exploitation is feasible. They find that wireless communications channels allow long-distance vehicle control, location tracking, in-cabin audio exfiltration, and theft. The study also discusses the structural characteristics of the automotive ecosystem that contribute to these vulnerabilities and highlights practical challenges in mitigating them. The research makes four main contributions: characterizing the threat model, conducting vulnerability analysis, assessing the utility of vulnerabilities, and providing recommendations to enhance automotive system security. The authors conclude by emphasizing the need for deeper architectural redesign to address the identified security issues.The paper "Comprehensive Experimental Analyses of Automotive Attack Surfaces" by Stephen Checkoway et al. explores the security vulnerabilities of modern automobiles, focusing on their external attack surfaces.
