滴水逆向-打印数据目录

核心代码部分

//简单打印可选PE头的数据目录
 
VOID FileBufferPrintDataDirectory(IN LPVOID pFileBuffer)
{
    PIMAGE_DOS_HEADER pDosHeader = NULL;
    PIMAGE_NT_HEADERS pNTHeader = NULL;

    PIMAGE_DATA_DIRECTORY pDataDirectory = NULL;
 
    if (pFileBuffer == NULL)
    {
        printf("FileBuffer 获取失败!\r\n");
        return;
    }
 
    //判断是否是有效的MZ标志
    if (*((PWORD)pFileBuffer) != IMAGE_DOS_SIGNATURE)
    {
        printf("无效的MZ标识\r\n");
        return;
    }
    pDosHeader = (PIMAGE_DOS_HEADER)pFileBuffer;
 
    //判断是否是有效的PE标志
    if (*((PDWORD)((DWORD)pFileBuffer+pDosHeader->e_lfanew)) != IMAGE_NT_SIGNATURE)
    {
        printf("无效的PE标记\r\n");
        return;
    }
    //定位NT头
    pNTHeader = (PIMAGE_NT_HEADERS)((DWORD)pFileBuffer+pDosHeader->e_lfanew);
    pPEHeader = (PIMAGE_FILE_HEADER)(((DWORD)pNTHeader)+4);
    pOptionHeader = (PIMAGE_OPTIONAL_HEADER32)((DWORD)pPEHeader+IMAGE_SIZEOF_FILE_HEADER);
    //	pDataDirectory = PIMAGE_DATA_DIRECTORY((&pOptionHeader->NumberOfRvaAndSizes + 1));
    pDataDirectory = pOptionHeader->DataDirectory;
    printf("\t\t RVA\t\t 大小\r\n");
 
    //打印相关信息测试
    //#define IMAGE_NUMBEROF_DIRECTORY_ENTRIES    16
 
    //下面是一种粗糙的遍历写法；
    /*

上述代码定义好头文件，然后在main入口调用即可，下面是执行后的效果；
