About Roald Nefs

I’m a security and platform engineer based in the Netherlands, currently CTO at Warpnet. Over the past decade I’ve worked on security and platform engineering at organizations like DUO, KPN, and CJIB.

Community

I co-organize BSides Groningen, BSides Amsterdam, and Cloud Native Groningen: grassroots events for the curious, the technical, and the occasionally reckless. I also run hands-on workshops on automotive security and hardware hacking, and operate a Car Hacking Village at conferences across Europe.

Open source

Most of my code lives on GitHub. I’ve contributed to projects like SaltStack, Prometheus, and rfcat, and maintain a few of my own. One of those is WebUSB CAN, the browser-based CAN console I use in my automotive workshops.

Off the keyboard

Outside of work, automotive security and hardware hacking are the rabbit holes I keep ending up in. The workshops and the Car Hacking Village all come from that hobby. I also tinker with electronics, RF, and lockpicking; the Tools page lists what’s currently on the bench.
