NOTE
When working with a closed-source application, an exploit developer will often
use a debugger to help understand how the closed-source application functions
internally. In addition to helping step through the program assembly instruc-
tions, it also allows a developer to see the current state of the registers,
examine the virtual memory space, and view other important process informa-
tion. These features are especially useful in later exploit stages when one must
determine the bad characters, size limitations, or any other issues that must be
avoided.
