  • Advice on embedded RE:

    • Figure out how things are layed out in memory

    • Get all the low-hanging fruit in terms of functions based on if you have symbols

    • Look for debug strings and use those to inform other functionality, work your way back.

    • Define your desired end-state: what is the overall goal of REing this?  Ignore branches that don't answer that.
