Exploiting Wireless Side Channels in EV Charging Systems - Security Vulnerabilities in CCS and NACS

Explore critical security vulnerabilities in electric vehicle charging systems through this DEF CON 31 Car Hacking Village presentation that examines wireless attack vectors in the Combined Charging System (CCS). Learn how charging cables inadvertently function as antennas, exposing power-line communication signals to potential exploitation using common radio equipment. Discover techniques for eavesdropping on charging communications and methods to remotely terminate charging sessions. Understand why these security flaws, known for years, persist in both CCS standards and the new North American Charging Standard (NACS), and examine potential solutions for securing these widely-deployed charging infrastructures.
