Hi Shub-Nigurrath !
Sorry first if I have a wrong idea. I think the IsBadReadPtr and IsBadWritePtr can not be used to check memory access right for a memory range of another process. In your code, you really call them to check read/write right for a memory range in your virtual memory process with the addess value is same as lpAddress (of beging loaded process).
FEARHQ, if one of a call to ReadProcessMemory failed, the protection flag of those memory pages will be not restored to original flag (je Failed). Some coders/programs uses PAGE_NOACCESS to allocate memory when need.
Regards,
TQN
