 Posted: Mon Sep 07, 2009 11:27 am Post subject: Injeccion Dll without dll |
 |
|
Hello everyone, this time I found a E0N code, the programmer, it's about dll injection, no dll.
Someone could spend this code to C#, (original version is in C++)?, It gives me errors!
 ! Thanks in advanced, code the here:
| Code: | #pragma hdrstop
#include <windows.h>
#include <tlhelp32.h>
#include <stdio.h>
//We create a pointer to the api that we inject
typedef int (WINAPI *datMessageBoxA) (HWND, LPCTSTR, LPCTSTR, UINT);
//the esctructure to inyect
struct datos
{
datMessageBoxA apiMessageBoxA;
char titulo [100];
char mensaje [100];
};
//declarating functions
DWORD GetAdres(char *module, char *function);
//the function to inyect
DWORD inyectada (datos *data)
{
data -> apiMessageBoxA (0, data->mensaje, data->titulo, 0);
return 0;
}
//inject function
void inyectora()
{
int pid;//This is the pid of the process in which you want to inject
HANDLE proc; //The handle of the process in which inject
datos dat; //The data type of the structure
DWORD TamFun; //The size of the function to inject
void* esp; // Memory location where we will copy our role
buscar
HANDLE handle = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0); //Get the PID
PROCESSENTRY32 procinfo = { sizeof(PROCESSENTRY32) };
while(Process32Next(handle, &procinfo))
{
if(!strcmp(procinfo.szExeFile, "notepad.exe"))
{
CloseHandle(handle);
pid = procinfo.th32ProcessID;
}
}
CloseHandle(handle);
//We open the process in which we inject
proc = OpenProcess(PROCESS_CREATE_THREAD | PROCESS_VM_OPERATION | PROCESS_VM_WRITE, false, pid);
//We put the address of the api in the structure function calling to GetAdres
dat.apiMessageBoxA = (datMessageBoxA) GetAdres ("USER32.DLL", "MessageBoxA");
//Inicializamos las variables que contendrán el mensaje
sprintf(dat.mensaje,"inyeccion Complete :D");
sprintf(dat.titulo,"Hiii");
//Reserve space for our structure in the process to inject and write
datos *dat_ = (datos*) VirtualAllocEx(proc, 0, sizeof(datos), MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE);
WriteProcessMemory(proc, dat_, &dat, sizeof(datos), NULL);
//We estimate the size of the function to inject.
TamFun = (long unsigned int) inyectora - (long unsigned int)inyectada;
//Reserve space for the function, write it and create a thread
esp = VirtualAllocEx(proc, 0, TamFun, MEM_RESERVE | MEM_COMMIT, PAGE_EXECUTE_READWRITE);
WriteProcessMemory(proc, esp, (void*)inyectada, TamFun, NULL);
CreateRemoteThread(proc, NULL, 0, (LPTHREAD_START_ROUTINE) esp, dat_, 0, NULL);
}
void main()
{
inyectora();
}
// Function returns a DWORD us with the address of an API
DWORD GetAdres(char *module, char *function)
{
HMODULE dh = LoadLibrary(module);
DWORD pf = (DWORD)GetProcAddress(dh,function);
FreeLibrary(dh);
return pf;

well, that's my problem, this code injects a msgbox, I want to change the values in the memory of notepad, how do I do?.
I want to do it the same way in which the msgbox was performed, because if I do it with notepad, i can do with other processes.
Thanks in advance, see you son!.

what exactly do you want notepad to do with api injection?
i mean the allocated address must be called by other address for the api to execute?!
btw sounds cool api injection never heard it =D

Your English is poor, so it is hard to understand what you want to do.
Do you want to change the text in notepad?

that is a stupid method for just changing one address. i recommend writeprocessmemory
are you sure you want to use that method ?

Of course! I say because I'll do in Counter Strike, and inject SXE does not allow me to WriteProcessMemory therefore wish to use this method 100% Functional.  
EH SOMEONE CAN HELP ME ?

No es posible convertirlo al C# porque tendrias que declarar la funcion inyectada() en su exe de C# para escribirlo en notepad con WriteProcessMemory y C# consiste de .NET que es diferente del assembly del C/++ (o sea x86). Entonces puedes escribir un DLL en C++ y exportar la funcion inyectora() (y cambiar messageboxA a cualquier API que quieres) y llamarlo por pInvoke
(It's not possible to convert this exact code to C# because C# uses .NET assembly which isn't the same as x86 assembly so you couldn't write the function to an x86 process, just make a C++ dll and export the inject() function and call it with pInvoke)

Si no se puede hacer en C#, usted tiene la API que yo necesito para la edicion de memoria en C++?.
Lo que veo que me esta diciendo es que cree una Dll aparte y la inyecte, pero eso es lo que no deseo hacer.
Si en dado caso por ultimas busquedas que se hagan y aun asi sea imposible hacer inyeccion de dll sin dll en C#, se podría entonces hookear las APIS WriteProcessMemory, ReadProcessMemory, entre otras?, podría decirme como hookearlas para poder usarlas?; si no se puede hacer entonces me podría decir algún metodo para poder usarlas que no sea inyeccion dll?.
Gracias por su ayuda, espero una respuesta.
