There are job postings lately for hacking and reverse engineering embedded systems, particularly from defense contractors. I suppose they would be doing things like capturing and hacking enemy drones.

That’s not exactly my interest, but shows there is a demand for breaking into embedded systems. I personally want to develop these skills just to repair shit like washing machines that lock me out of their protectionist PCBs designed for premature obsolescence/destruction. When the washing machine manufacturer gives me the middle finger after asking for a service manual, I need to return the sentiment and fix the thing without their support (yes, it has serial ports on the PCB).

In any case, the course should cover using tools like Bus Pirates and Flipper Zero. Anything out there in open university courses?
