After solving few crackmes I tried to take one step further and move on "real life" reversing tasks, targeting a known win7 program's password check feature.
The program in question obviously doesn't store interesting strings in memory, so I tried another approach, that so far worked well in test-scenarios and in crackmes. The prompt for the password itself uses a simple edit control, so I instantly looked for executable modules -> USER32.dll and found the GetWindowTextW offset (I know it may be using alternative ways to retrieve text, but that was not the problem) Setting a breakpoint there and trying to f9-run the program causes it to crash.
I'm new in reversing and debuggers, and I don't really know what may be causing the issue, or where should I look to solve it.
PS: could this be a good approach for the task ?
