Using dynamic reverse engineering – an example

I've prepared a variant of the previous example that will pose us some challenges. I will show you how to overcome these challenges both statically and dynamically in order for you to be able to compare the amount of effort needed in both cases.

The rule of thumb when comparing dynamic and static approaches is that 99% of the time, dynamic approaches are just easier and should be given priority if possible (don't forget that you may not be able to get access to JTAG/SWD or other on-chip debugging protocols).

In this section, we will also learn how to break where we want, inspect memory with GDB, and all this good stuff!

The target program is located here in the folder you cloned, in the ch12 folder.

First, let's start by loading it into Ghidra and inspect it superficially. Pay attention to setting the correct architecture and base address in Ghidra's loading window (refer to the previous chapter if...
