I am new to reverse engineering and after some research, I haven't found a clear way to do what I want to do.
I have an ELF file, but not the original source code that generated it. It is really simple and just prints some numbers. I wanted to make a small change in the range of numbers it prints. I have disassembled it and figured out where the change must be made, but I am not sure how to make this change.
Is there a way to edit disassembled code and still generate an executable file? Or should I figure out where in the hex file is the corresponding information that I want to change and use a hex editor?
