In this section, we are going to reverse the passcode.exe program. As a practice run, we'll gather the information we need by using static and dynamic analysis tools. We'll use some of the Windows tools that were introduced in the previous chapters. Do not be limited by the tools that we are going to use here. There are a lot of alternatives that can do the same task.  The OS environment used to analyze this program is a Windows 10, 32-bit, 2 GB RAM, 2 core processor in a VirtualBox.
