 Posted: Wed Aug 17, 2011 1:34 pm Post subject: [SOLVED] c++ dll injector problem |
 |
|
Hello i am new to this forum and i need help with some c++ code.
I have a problem with my dll injector i just created in c++. I am not sure if the problem is caused by the injector or by the game. I tryed to inject a dll in war3.exe and every time it fail. I injected the same dll with the same injector in other processes and works fine. Here is the code of my dll injector if someone could make me understand why i can't inject in war3.exe i would be happy.
| Code: |
#include <iostream>
#include <windows.h>
#include <Tlhelp32.h>
using namespace std;
//get process id
bool PidByName(char* name, PROCESSENTRY32 &s)
{
HANDLE hSnapshot;
PROCESSENTRY32 pStruct;
hSnapshot = CreateToolhelp32Snapshot(0x2, 0);
if( hSnapshot == INVALID_HANDLE_VALUE )
{
return false;
}
else {
bool ch;
pStruct.dwSize = sizeof(PROCESSENTRY32);
ch = Process32First(hSnapshot, &pStruct);
bool f=false;
while(ch && !f)
{
if(!strcmp(pStruct.szExeFile,name))f=true;
else ch = Process32Next(hSnapshot, &pStruct);
}
if(f) {s=pStruct;return true;}
else return false ;
}
}
int main()
{
PROCESSENTRY32 prc;
char *dst;
dst = new char[1024];
cout<<"Path dll: ";cin>>dst;
char* nume;cout<<"Process name: ";
nume = new char[256];
cin>>nume;
if(!PidByName(nume,prc))cout<<"No process with that name.\n";
else
{
HANDLE hThread;
HANDLE hProc;
char dllPath[1024];
strcpy(dllPath, dst);
void *destAdr; // the address (in the remote process) where
// dllPath will be copied to;
DWORD hLibModule; //Base address of loaded module (==HMODULE);
HMODULE hKernel32 = GetModuleHandle("Kernel32");
hProc = OpenProcess(PROCESS_ALL_ACCESS, FALSE, prc.th32ProcessID);
// 1. Allocate memory in the remote process for dllPath
// 2. Write dllPath to the allocated memory
destAdr = VirtualAllocEx(hProc,
NULL,1024,
MEM_COMMIT,
PAGE_EXECUTE_READWRITE);
WriteProcessMemory(hProc,
destAdr,
(void*)dllPath,
sizeof(dllPath),
NULL);
// Load "my.dll" into the remote process
// (via CreateRemoteThread & LoadLibrary)
hThread = CreateRemoteThread(hProc,
NULL,
0,
(LPTHREAD_START_ROUTINE)GetProcAddress(hKernel32, "LoadLibraryA"),
destAdr,
0,
NULL);
WaitForSingleObject( hThread, INFINITE );
// Get handle of the loaded module
if(GetExitCodeThread( hThread, &hLibModule )!=0)cout<<"\nGetExitCodeThread done";
else cout<<"\nGetExitCodeThread error";
// Clean up
CloseHandle( hThread );
VirtualFreeEx(hProc, destAdr, sizeof(dllPath), MEM_RELEASE );
// Unload "my.dll" from the target process
// (via CreateRemoteThread & FreeLibrary)
hThread = CreateRemoteThread(hProc,
NULL,
0,
(LPTHREAD_START_ROUTINE)GetProcAddress( hKernel32,"FreeLibrary" ),
(void*)hLibModule,
0,
NULL );
WaitForSingleObject( hThread, INFINITE );
// Clean up
CloseHandle( hThread );
}
return 0;
} |
it fails at "GetExitCodeThread()" function. I injected that dll with cheat engine into war3.exe process and it works so it seems like the problem is in this code.

If it works for other processes, I think the game has some kind of protection.
Also I believe we're not allowed to talk about online games.

| Warcraft III is not only an online game. and i want to inject only for the purpose of learning. if i want to inject a dll in this game for hacking i will use cheat engine to inject a specific dll. With cheat engine i can succesfully inject my dll. I can't figure out the problem.

Sorry, I thought war3 was referring to warrock.

Problem solved topic can be close. For this injector to work properly you need to set debug privilage.
| Code: | BOOL SetDebugPrivileges()
{
BOOL bRET = FALSE;
TOKEN_PRIVILEGES tp;
HANDLE hToken;
if (LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &tp.Privileges[0].Luid))
{
if (OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, &hToken))
{
if (hToken != INVALID_HANDLE_VALUE)
{
tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
tp.PrivilegeCount = 1;
if (AdjustTokenPrivileges(hToken, FALSE, &tp, 0, 0, 0))
bRET = TRUE;
CloseHandle(hToken);
}
}
}
return bRET;
}
} |
Call this function befor call OpenProcess() and will work

Or just don't use PROCESS_ALL_ACCESS and specify the flags you actually need.
