Простой пакетный регистратор с Detours 3.0 Express

Моя система: Microsoft Windows XP Professional 32-разрядная

IDE / компилятор: Microsoft Visual C ++ 2010 Express Edition

Библиотека: Detours 3.0 Express

Цель: написать простой регистратор пакетов.

Мой код:

mydll.cpp

#include <cstdio>
#include <windows.h>
#include <detours.h>

#pragma comment(lib,"detours.lib")
#pragma comment(lib,"ws2_32.lib")

int (WINAPI *pSend)(SOCKET s, const char* buf, int len, int flags) = send;
int WINAPI MySend(SOCKET s, const char* buf, int len, int flags);
int (WINAPI *pRecv)(SOCKET s, char* buf, int len, int flags) = recv;
int WINAPI MyRecv(SOCKET s, char* buf, int len, int flags);

FILE* pSendLogFile;
FILE* pRecvLogFile;

int WINAPI MySend(SOCKET s, const char* buf, int len, int flags)
{
fopen_s(&pSendLogFile, "C:\\SendLog.txt", "a+");
fprintf(pSendLogFile, "%s\n", buf);
fclose(pSendLogFile);
return pSend(s, buf, len, flags);
}

int WINAPI MyRecv(SOCKET s, char* buf, int len, int flags)
{
fopen_s(&pRecvLogFile, "C:\\RecvLog.txt", "a+");
fprintf(pRecvLogFile, "%s\n", buf);
fclose(pRecvLogFile);
return pRecv(s, buf, len, flags);
}

BOOL WINAPI DllMain(HINSTANCE hinst, DWORD dwReason, LPVOID reserved)
{
if (DetourIsHelperProcess()) {
return TRUE;
}

if (dwReason == DLL_PROCESS_ATTACH) {
DetourRestoreAfterWith();

DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourAttach(&(PVOID&)pRecv, MyRecv);
DetourTransactionCommit();

DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourAttach(&(PVOID&)pSend, MySend);
DetourTransactionCommit();

}
else if (dwReason == DLL_PROCESS_DETACH) {
DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourDetach(&(PVOID&)pRecv, MyRecv);
DetourTransactionCommit();

DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourDetach(&(PVOID&)pSend, MySend);
DetourTransactionCommit();

}
return TRUE;
}

injector.cpp

#include <windows.h>
#include <detours.h>

#pragma comment(lib,"detours.lib")

int main(int argc, char *argv[])
{
STARTUPINFO si;
PROCESS_INFORMATION pi;

ZeroMemory(&si, sizeof(si));
ZeroMemory(&pi, sizeof(pi));
si.cb = sizeof(si);
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_SHOW;

if(!DetourCreateProcessWithDllEx("C:\\Program Files\\Internet Explorer\\iexplore.exe",
NULL, NULL, NULL, TRUE,
CREATE_DEFAULT_ERROR_MODE | CREATE_SUSPENDED,
NULL, NULL, &si, &pi,
"C:\\Documents and Settings\\Dawid\\Pulpit\\detours_test\\Detours_test\\Release\\Detours_test.dll", NULL))
MessageBox(0, "failed", 0, 0);
else
MessageBox(0, "success", 0, 0);

ResumeThread(pi.hThread);

WaitForSingleObject(pi.hProcess, INFINITE);

CloseHandle(&si);
CloseHandle(&pi);

return EXIT_SUCCESS;
}

Сообщение об ошибке:

(iexplore.exe) Приложение

Вопрос:
Что не так с моим кодом? Почему я получаю эту ошибку?

Решение

РЕШИТЬ

Я убрал функцию:

DetourRestoreAfterWith();

из DLL и добавить в функцию DLL:

extern "C" __declspec(dllexport) void dummy(void){
return;
}

Теперь это работает!

mydll.cpp

#include <cstdio>
#include <windows.h>
#include <detours.h>

#pragma comment(lib,"detours.lib")
#pragma comment(lib,"ws2_32.lib")

int (WINAPI *pSend)(SOCKET s, const char* buf, int len, int flags) = send;
int WINAPI MySend(SOCKET s, const char* buf, int len, int flags);
int (WINAPI *pRecv)(SOCKET s, char* buf, int len, int flags) = recv;
int WINAPI MyRecv(SOCKET s, char* buf, int len, int flags);

FILE* pSendLogFile;
FILE* pRecvLogFile;

int WINAPI MySend(SOCKET s, const char* buf, int len, int flags)
{
fopen_s(&pSendLogFile, "C:\\SendLog.txt", "a+");
fprintf(pSendLogFile, "%s\n", buf);
fclose(pSendLogFile);
return pSend(s, buf, len, flags);
}

int WINAPI MyRecv(SOCKET s, char* buf, int len, int flags)
{
fopen_s(&pRecvLogFile, "C:\\RecvLog.txt", "a+");
fprintf(pRecvLogFile, "%s\n", buf);
fclose(pRecvLogFile);
return pRecv(s, buf, len, flags);
}

extern "C" __declspec(dllexport) void dummy(void){
return;
}

BOOL WINAPI DllMain(HINSTANCE hinst, DWORD dwReason, LPVOID reserved)
{
if (DetourIsHelperProcess()) {
return TRUE;
}

if (dwReason == DLL_PROCESS_ATTACH) {
//DetourRestoreAfterWith();

DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourAttach(&(PVOID&)pSend, MySend);
DetourTransactionCommit();

DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourAttach(&(PVOID&)pRecv, MyRecv);
DetourTransactionCommit();
}
else if (dwReason == DLL_PROCESS_DETACH) {
DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourDetach(&(PVOID&)pSend, MySend);
DetourTransactionCommit();

DetourTransactionBegin();
DetourUpdateThread(GetCurrentThread());
DetourDetach(&(PVOID&)pRecv, MyRecv);
DetourTransactionCommit();
}
return TRUE;
}

injector.cpp

#include <windows.h>
#include <detours.h>

#pragma comment(lib,"detours.lib")

int main(int argc, char *argv[])
{
STARTUPINFO si;
PROCESS_INFORMATION pi;

ZeroMemory(&si, sizeof(si));
ZeroMemory(&pi, sizeof(pi));
si.cb = sizeof(si);
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_SHOW;

if(!DetourCreateProcessWithDllEx("C:\\client.exe",
NULL, NULL, NULL, TRUE,
CREATE_DEFAULT_ERROR_MODE | CREATE_SUSPENDED,
NULL, NULL, &si, &pi,
"C:\\Documents and Settings\\Dawid\\Pulpit\\detours_test\\Detours_test\\Release\\Detours_test.dll", NULL))
MessageBox(0, "failed", 0, 0);
else
MessageBox(0, "success", 0, 0);

ResumeThread(pi.hThread);

WaitForSingleObject(pi.hProcess, INFINITE);

CloseHandle(&si);
CloseHandle(&pi);

return EXIT_SUCCESS;
}
