I have written DLL injector. I used CreateRemoteThread to inject my DLL to process and all was good. Now i am trying inject DLL to process by undocumented function - NtCreateThreadEx. I have written injector but he is not working.
When i use 32 bit injector to inject 32 bit DLL to 32 bit process all working good. Problem is when i use 64 bit injector to inject 64 bit DLL to 64 bit process.
My DLL code:
#include <windows.h> ///Compilation with option -m64 extern "C" BOOL __stdcall DllMain(HMODULE hDLL, DWORD Reason, LPVOID Reserved) { MessageBox( NULL, "MESSAGE FROM 64 BIT DLL", "Lorem ipsum", MB_ICONINFORMATION | MB_OKCANCEL ); return 0; } My TestApp code
#include <iostream> #include <windows.h> int main() { std::cout << " Lorem IPSUM" << std::endl; //HMODULE HDLL = LoadLibraryA("dll64.dll"); //std::cout << "Error: " << GetLastError() << std::endl; while(1) { std::cout << "petla" << std::endl; Sleep(5000); } return 0; } My injector code:

I use to compile on 64 bit architecture: g++ (tdm64-1) 5.1.0 I am working on Virus Windows 7 64 bit as normal user. Run as administrator doesn't help. I dont know why it doesn't work, what i doing wrong.
PS: When i use 32 bit injector to inject 32 bit DLL to 32 bit process, function NtCreateThreadEx return code of error 1300 but my DLL execute. In 32 bit version TestApp GetLastError return code 1114. I use to compile on 32 bit architecture: g++ (tdm-2) 4.8.1

My injector is working when i use him to inject DLL to other process in my user space (i am working as normal user) but it is not working when i am injecting to csrss.exe (or other system's process). I get code of error 5 - Access Denied, when i run injector as Administrator i get code of error 0 (SUCCESS?) but my DLL not aborting process ( abort() - i try do BSoD).
I read about Session Separation and i think it is reason of my problem so i have one question: How i can hacking Windows :) If it is imposibble can i inject DLL as normal user to proces in Administrator context (or other normal user's process) ?
