I'm a penetration tester working in automotive and EV charging security. This blog is where I document what I learn while assessing connected vehicles, EV chargers, embedded devices and the technologies that power modern mobility. You'll find practical notes, architecture breakdowns, protocol deep dives, original diagrams and security research focused on OCPP, ISO 15118, firmware, wireless interfaces and real-world attack surfaces. My goal is simple: make complex automotive security topics easier to understand through hands-on engineering rather than marketing buzzwords.
