Raymond Felch // Preface: I began my exploration of reverse-engineering firmware a few weeks back (see “JTAG – Micro-Controller Debugging“), and although I made considerable progress finding and identifying the JTAG (Joint Test Action Group) pins on my target board (Samsung S3C4510 CPU) Linksys BEFSR41 router, there were complications. I ran into a number of […]
Raymond Felch // Being an embedded firmware engineer for most of my career, I quickly became fascinated when I learned about reverse engineering firmware using JTAG. I decided to take on this project as an opportunity to learn more about this somewhat obscure and often overlooked attack vector. excerpt from: https://en.wikipedia.org/wiki/JTAG JTAG (named after […]
