WINDOWS黑客基础(6):查看文件里面的导入表

int main(void)
{
    HANDLE hFile = CreateFile("D:\\Shipyard.exe",
                               GENERIC_READ,
                               FILE_SHARE_READ,
                               NULL,
                               OPEN_EXISTING,
                               FILE_ATTRIBUTE_NORMAL,
                               NULL);

    HANDLE hFileMapping = CreateFileMapping(hFile,NULL,FILE_READ_ONLY,0,0,NULL);

    LPBYTE lpBaseAddress = (LPBYTE)MapViewOfFile(hFileMapping,FILE_MAP_READ,0,0,0);
    
    PIMAGE_DOS_HEADER pDostHeader = (PIMAGE_DOS_HEADER)lpBaseAddress;

    PIMAGE_NT_HEADERS pNtHeader = (PIMAGE_NT_HEADERS)(lpBaseAddress + pDostHeader->e_lfanew);
    
    DWORD rva_import_table = pNtHeader->OptionalHeader.DataDirectory[IMAGE_DIRECTORY_ENTRY_IMPORT].VirtualAddress;

    PIMAGE_IMPORT_DESCRIPTOR pImport = 
        (PIMAGE_IMPORT_DESCRIPTOR)ImageRvaToVa(pNtHeader,
                                               lpBaseAddress,
                                               rva_import_table,
                                               NULL);

    IMAGE_THUNK_DATA *data = NULL;

    while ( pImport->Name != NULL)
    {
        LPCTSTR szDllName = (LPCTSTR)ImageRvaToVa(pNtHeader,lpBaseAddress,pImport->Name,NULL);
        
        PIMAGE_THUNK_DATA pThunk = 
            (PIMAGE_THUNK_DATA)ImageRvaToVa(pNtHeader,
                                            lpBaseAddress,
                                            pImport->OriginalFirstThunk,
                                            NULL);

        printf("%s\n",szDllName);

        while (pThunk->u1.Function)
        {
            if (pThunk->u1.AddressOfData & IMAGE_ORDINAL_FLAG32)
            {
                printf("序号:%d\n",pThunk->u1.AddressOfData & 0xffff);
            }
            else
            {
                PIMAGE_IMPORT_BY_NAME pFunName = 
                    (PIMAGE_IMPORT_BY_NAME)ImageRvaToVa(
                    pNtHeader,
                    lpBaseAddress,
                    pThunk->u1.AddressOfData,
                    NULL
                    );

                printf("%s\n",pFunName->Name);
            }
            pThunk++;
        }

        pImport ++;
    }
}

这节也没什么难的,主要还是PE文件的解析,还要会运用ImageRvatoVa这个函数还取得对应的内存地址,就能解析出来了
