Niel Nielsen is an embedded systems developer and hardware security researcher based in Denmark. He publishes research on RFID security, firmware reverse engineering, and embedded Linux at sec1.dk, where the blog posts that became this book first appeared.
He is an active contributor to the ChameleonUltra open-source firmware project, with merged work covering LF protocol readers, HF passive sniffing, raw signal analysis, and standalone operation modes.
His tooling of choice is a Black Magic Probe, an Arch Linux workstation, and whatever hardware refuses to give up its secrets quietly. When not pulling firmware out of things that were not designed to be opened, he develops applications for Sailfish OS and contributes to open-source security tooling under the handle nieldk on GitHub and Codeberg.
