The Toolkit
Automotive
Modern vehicles are networks on wheels. The controllers behind the engine, brakes, locks, dashboard, and infotainment talk to each other over the CAN bus, and car security work means getting onto that bus to read what’s being said and, carefully, to send messages of your own. It’s a specialized corner of security with growing importance as cars get more connected, and it needs a CAN interface (a USB-to-CAN adapter, or a SocketCAN-compatible device) to reach real hardware.
