今天学习导入表,于是便通过程序将获取IAT的过程实现一下,各位看官发现什么问题,请多指教。谢谢!废话不多说,下面是代码: #include <iostream> #include <windows.h> #include <winnt.h> using namespace std; int main(int argc, char* argv[]) { if (argc != 2) { cout << "Usage: " << argv[0] <<" "<<argv[1]<<endl; exit(1); } HANDLE hFile = NULL; IMAGE_DOS_HEADER * pDosHeader = NULL; cout << argv[0] << " " << argv[1] << endl; WCHAR pwchar[255] = {0}; MultiByteToWideChar(CP_ACP, 0, argv[1], sizeof(argv[1]) + 1, pwchar, sizeof(pwchar)/sizeof(pwchar[0])); //hFile = CreateFile("D:\\project\\PEInfo\\Debug\\Loadsys.exe", GENERIC_READ, FILE_SHARE_READ| FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); hFile = CreateFile(argv[1], GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); if (hFile == INVALID_HANDLE_VALUE) cout << "CreateFile Error" << GetLastError() << endl; HANDLE hMap = 0; hMap = CreateFileMapping(hFile, NULL, PAGE_READONLY, 0, 0, NULL); if (!hMap) cout << "CreatefileMapping Error !" << endl; void * lpMemory = MapViewOfFile(hMap, FILE_MAP_READ, 0, 0, 0); pDosHeader = (IMAGE_DOS_HEADER *)lpMemory; if (pDosHeader->e_magic != IMAGE_DOS_SIGNATURE) cout << "This File is not a PE File !" << endl; IMAGE_NT_HEADERS* pNtHeader = (IMAGE_NT_HEADERS*)((BYTE*)pDosHeader + pDosHeader->e_lfanew); cout << "----------------------------------------------------------------------" << endl; cout << "Number of Section: " << pNtHeader->FileHeader.NumberOfSections << endl; for (int i = 0; i < pNtHeader->FileHeader.NumberOfSections; ++i) { IMAGE_SECTION_HEADER * pSectionHeader = (IMAGE_SECTION_HEADER *)((pNtHeader->FileHeader.SizeOfOptionalHeader + 24 + (BYTE*)pNtHeader) + i * 0x28); cout << "Setction Name: " << pSectionHeader->Name << endl; } cout << "----------------------------------------------------------------------" << endl; IMAGE_IMPORT_DESCRIPTOR * pImportTabe = (IMAGE_IMPORT_DESCRIPTOR *)(pNtHeader->OptionalHeader.DataDirectory[1].VirtualAddress + (BYTE*)pDosHeader); IMAGE_IMPORT_DESCRIPTOR* pOriginalImportTable = pImportTabe; IMAGE_THUNK_DATA * pThunk = nullptr; IMAGE_IMPORT_BY_NAME* pINT = nullptr; DWORD n = 0; while (pImportTabe->Name) { cout <<"+-------------------------------------------------------------------"<< endl; cout << "+动态库:" << pImportTabe->Name + (BYTE*)pDosHeader << endl; cout << " +----导入函数名称表:" << endl; pThunk = (IMAGE_THUNK_DATA *)(pImportTabe->OriginalFirstThunk + (BYTE*)pDosHeader); while (pThunk->u1.Function) { pINT = (IMAGE_IMPORT_BY_NAME*)(pThunk->u1.Function + (BYTE*)pDosHeader); cout <<" |------"<< pINT->Hint << " : " << pINT->Name << endl; cout << ((DWORD*)(pImportTabe->FirstThunk + (BYTE*)pDosHeader) + n)<<endl; //printf("%x \n", ((DWORD*)(pImportTabe->FirstThunk + (BYTE*)pDosHeader) + n)); n++; pThunk = (IMAGE_THUNK_DATA*)((BYTE*)pThunk + 4); } pImportTabe = (IMAGE_IMPORT_DESCRIPTOR*)((BYTE*)pImportTabe + 20); } cout << "----------------------------------------------------------------------" << endl; return 0; }
