Description

My code as follows:

BOOL WINAPI HookedCreateProcessAsUserW(
HANDLE hToken,
LPCWSTR lpApplicationName,
LPWSTR lpCommandLine,
LPSECURITY_ATTRIBUTES lpProcessAttributes,
LPSECURITY_ATTRIBUTES lpThreadAttributes,
BOOL bInheritHandles,
DWORD dwCreationFlags,
LPVOID lpEnvironment,
LPCWSTR lpCurrentDirectory,
LPSTARTUPINFOW lpStartupInfo,
LPPROCESS_INFORMATION lpProcessInformation
) {
LOG_INFO(L"===sunlei22===CreateProcessAsUserW is called with application: %ls, commandline: %s, currentdirectory: %s, desktop: 
%s\n", lpApplicationName, lpCommandLine, lpCurrentDirectory, lpStartupInfo->lpDesktop);

return OriginalCreateProcessAsUserW(
    hToken, lpApplicationName, lpCommandLine, lpProcessAttributes, lpThreadAttributes,
    bInheritHandles, dwCreationFlags, lpEnvironment, lpCurrentDirectory, lpStartupInfo, lpProcessInformation
);}

bool ProcessAttach()
{
OriginalCreateProcessAsUserW = CreateProcessAsUserW;
OriginalCreateProcessW = CreateProcessW;

DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourSetIgnoreTooSmall(TRUE);

LONG ret = 1;
do
{
    ret = DetourAttach(&(PVOID&)OriginalCreateProcessAsUserW, HookedCreateProcessAsUserW);
    if (ret != 0)
    {
        LOG_ERROR(L"DetourAttach for CreateProcessAsUserW failed\n");
        break;
    }
    ret = DetourAttach(&(PVOID&)OriginalCreateProcessW, HookedCreateProcessW);
    if (ret != 0)
    {
        LOG_ERROR(L"DetourAttach for CreateProcessW failed\n");
        break;
    }
} while (false);

if (ret == 0)
{
    LOG_ERROR(L"DetourAttach Successfully\n");
}
else
{
    LOG_ERROR(L"DetourAttach failed\n");
}
PVOID* ppbFailedPointer = NULL;
LONG error = DetourTransactionCommitEx(&ppbFailedPointer);
if (error != 0)
{
    LOG_ERROR(L"DetourTransactionCommitEx failed, error %ld (%p/%p)\n", error, ppbFailedPointer, *ppbFailedPointer);
}
return ret;
}

CreateProcessW can be hooked, but CreateProcessAsUserW not work.

Research direction

No repository file or test is named.
