A screenshot of the opening paragraphs of my blog post. Text: Recently, I’ve been obsessed with hacking on embedded QNX systems - inspired by my own car’s head unit! As part of this, I’ve been looking to dump the device’s firmware for future static analysis. On other car head units, I’ve achieved this by simply plugging in a USB drive - mount it, dd over a disk images, and huzzah! You’re done! But this time, this system doesn’t have any USB ports… But it does have an ethernet interface!
