——PE结构及加壳的一种实现方式
重难点：
- 对c语言指针的使用
- 编程对exe类型文件的PE结构进行解析
- 编程实现PE信息的修改，为加壳做准备
- 对win32一些函数的使用
- 一种新的二进制壳的思路并通过C语言编程实现（可以抵挡静态分析）
一、PE解析（对一些重要的位置进行解释）
- DOS头
0x00 WORD e_magic; //**必须是MZ（人名缩写）开始的地方，判断是不是PE文件
0x02 WORD e_cblp;
0x04 WORD e_cp;
0x06 WORD e_crlc;
0x08 WORD e_cparhdr;
0x0a WORD e_minalloc;
0x0c WORD e_maxalloc;
0x0e WORD e_ss;
0x10 WORD e_sp;
0x12 WORD e_csum;
0x14 WORD e_ip;
0x16 WORD e_cs;
0x18 WORD e_lfarlc;
0x1a WORD e_ovno;
0x1c WORD e_res[4];
0x24 WORD e_oemid;
0x26 WORD e_oeminfo;
0x28 WORD e_res2[10];
0x3c DWORD e_lfanew **指向真正PE文件开始的地方，从开始的地方的偏移量
- 中间是垃圾数据（对于逆向分析来说是无用的数据，一些程序运行的备注信息，当我们进行新增节时，若头部信息不足，可以修改e_lfanew，把这块信息清除改为我们想要插入的数据）
- NT头包含了 标准PE头 和 可选PE头（很重要***）
0x00 DWORD Signature; 此处数据转换成英文是PE
0x04 _IMAGE_FILE_HEADER FileHeader;跳到标准pe头
0x18 _IMAGE_OPTIONAL_HEADER OptionalHeader;
- 标准PE头
0x00 WORD Machine;* 能在什么样的CPU上运行 0是任何CPU 14C是能在386以及后续处理器上运行
0x02 WORD NumberOfSections;* 一共有多少个节，分了多少节（除了头以外）
0x04 DWORD TimeDateStamp;*时间戳 检查map文件与exe的时间戳是否一样，不一样会出问题（map存储函数说明、地址）
0x08 DWORD PointerToSymbolTable;
0x0c DWORD NumberOfSymbols;
0x10 WORD SizeOfOptionalHeader;*可选PE头的大小（标准pe头和doc头是固定的）
0x12 WORD Characteristics; 每个位有不同的含义
24字节
- 可选PE头
0x00 WORD Magic;* 32位pe文件是10B 64位pe文件是20B
0x02 BYTE MajorLinkerVersion;
0x03 BYTE MinorLinkerVersion;
0x04 DWORD SizeOfCode;* 代码节所有字节的和，每一节必须是FileAlignment的整数倍，编译器进行填充（没用，更改了仍能正常运行）发展到现在没用了
0x08 DWORD SizeOfInitializedData;* 已初始化数据的大小，性质和上面相同（设立初值）
0x0c DWORD SizeOfUninitializedData;* 未初始化数据的大小，性质和上面相同（没有设立初值）
0x10 DWORD AddressOfEntryPoint;* 程序入口，在文件中，在内存中要加上imagebase：为了空出保护区和模块对齐
0x14 DWORD BaseOfCode;* 代码基址，编译器填充，没用 正常情况下程序入口在代码中，但可以更改
0x18 DWORD BaseOfData;* 数据基址，编译器填充，没用（改了不会影响运行）
0x1c DWORD ImageBase;* 最重要，在内存中运行的实际基址 一个exe是由一堆pe文件组成（会用到多个dll）
0x20 DWORD SectionAlignment;* 中间0的大小在内存中
0x24 DWORD FileAlignment;* 中间0的大小在文件中（未运行）根据编译器版本两者可能相同可能不同
0x28 WORD MajorOperatingSystemVersion;
0x2a WORD MinorOperatingSystemVersion;
0x2c WORD MajorImageVersion;
0x2e WORD MinorImageVersion;
0x30 WORD MajorSubsystemVersion;
0x32 WORD MinorSubsystemVersion;
0x34 DWORD Win32VersionValue;
0x38 DWORD SizeOfImage;* 在内存中拉伸后的大小，可以比实际大，但必须是SectionAlignment的整数倍，对齐便于遍历
0x3c DWORD SizeOfHeaders;头+节表在文件中对齐后的大小，必须是FileAlignment的整数倍，对齐
0x40 DWORD CheckSum;* 校验和WORD，两两相加后存入，自然溢出，验证是否出错
0x44 WORD Subsystem;
0x46 WORD DllCharacteristics;
0x48 DWORD SizeOfStackReserve;* 初始化时保留栈的大小（最大值）
0x4c DWORD SizeOfStackCommit;*实际提交的大小
0x50 DWORD SizeOfHeapReserve;* 初始化时保留堆的大小
0x54 DWORD SizeOfHeapCommit;* 实际提交的大小
0x58 DWORD LoaderFlags;
0x5c DWORD NumberOfRvaAndSizes;* 目录项数目（后面还有多少目录项）记录编译器向EXE加的数据的信息
实现的PE工具中列出的DOS头、PE头、可选PE头中的重要的信息
- 节表（每个节一个节表，依次排列，在NumberOfSections记录了节表的数量）
0x00 BYTE Name[IMAGE_SIZEOF_SHORT_NAME];//可能不存在‘/0’所以要用char[9]取出，可以更改，起个名字
union {
0x08 DWORD PhysicalAddress;
0x08 DWORD VirtualSize;//节表指向该节字节对齐之前，内存中数据的大小，可以不准确，不影响程序的运行
} Misc;
0x0c DWORD VirtualAddress;//指向的节区在内存中的偏移地址，加上imagebase
0x10 DWORD SizeOfRawData;//指向的节在文件对其之后的尺寸
0x14 DWORD PointerToRawData;//指向的节区在文件中的偏移，从零开始
0x18 DWORD PointerToRelocations;//无意义
0x1c DWORD PointerToLinenumbers;//无意义
0x20 WORD NumberOfRelocations;//无意义
0x22 WORD NumberOfLinenumbers;//无意义
0x24 DWORD Characteristics;//当前节的属性
属性对照表：（用了其中的一些位，并非全部，表示一些属性）
00000020h:包含可执行代码
00000040h：包含初始化的数据
00000080h：包含未初始化的数据
10000000h：该节为共享节
20000000h：可执行节
40000000h：可读节
80000000h：可写节
实现的PE工具中列出每一个节表重要的信息
- PE加载的过程：（每个exe程序运行在操作系统分配的4GB虚拟内存中）
1、根据SizeOfImage的大小，开辟一块缓冲区(ImageBuffer).
2、根据SizeOfHeader的大小，将头信息从FileBuffer拷贝到ImageBuffer
3、根据节表中的信息循环讲FileBuffer中的节拷贝到ImageBuffer中.
示意图：（在附件PE加载示意图中可见）
如何新建一个节（加壳所需）：
1、SizeOfHeader - (DOS + 垃圾数据 + PE标记 + 标准PE头 + 可选PE头 + 已存在节表)>= 2个节表的大小
2、需要修改的数据
1) 添加一个新的节(可以copy一份)
2) 在新增节后面 填充一个节大小的一串0（PE结构判断节表信息结束是判断当最后有一个节表长度大小的0表示节表信息到此结束）
3) 修改PE头中节的数量NumberOfSections
4) 修改sizeOfImage的大小
5) 再原有数据的最后，新增一个节的数据(内存对齐的整数倍).
6）修正新增节表的属性
函数代码（加壳程序中的添加新节函数）：
char* add_section_2(char* start_image){
char* start_new_image;
if(headers_file.SizeOfHeaders-headers_file.e_lfanew-headers_file.SizeOfOptionalHeader-24-headers_file.NumberOfSections*40<80){
//printf("space is not statific");
}
else{
//printf("space is statific");
start_new_image = (char*)malloc(headers_file.SizeOfImage+(flen/0x1000+1)*0x1000);
memset(start_new_image,0,headers_file.SizeOfImage+(flen/0x1000+1)*0x1000);
memcpy(start_new_image,start_image,headers_file.SizeOfImage);
*(short*)(start_new_image+headers_file.e_lfanew+6) = headers_file.NumberOfSections+1;
*(int*)(start_new_image+headers_file.e_lfanew+80) = headers_file.SizeOfImage+(flen/0x1000+1)*0x1000;
memcpy(start_new_image+headers_file.e_lfanew+headers_file.SizeOfOptionalHeader+24+headers_file.NumberOfSections*40,start_new_image+headers_file.e_lfanew+headers_file.SizeOfOptionalHeader+24,40);
*(char*)(start_new_image+headers_file.e_lfanew+headers_file.SizeOfOptionalHeader+24+headers_file.NumberOfSections*40) = 'a';
*(int*)(start_new_image+headers_file.e_lfanew+headers_file.SizeOfOptionalHeader+24+headers_file.NumberOfSections*40+0x24) = 0xe0000020;
*(int*)(start_new_image+headers_file.e_lfanew+headers_file.SizeOfOptionalHeader+24+headers_file.NumberOfSections*40+8) = (flen/0x1000+1)*0x1000;
printf("%x",(flen/0x1000+1)*0x1000);
int a;
if((sections.VirtualAddress+sections.VirtualSize)%0x1000==0){
a = sections.VirtualAddress+sections.VirtualSize;
}
else{
a = ((sections.VirtualAddress+sections.VirtualSize)/0x1000+1)*0x1000;
}
//sections.VirtualSize = headers_file.SectionAlignment;
if(sections.VirtualSize>sections.SizeOfRawData){
*(int*)(start_new_image+headers_file.e_lfanew+headers_file.SizeOfOptionalHeader+24+headers_file.NumberOfSections*40+12) = a;
}
else{
*(int*)(start_new_image+headers_file.e_lfanew+headers_file.SizeOfOptionalHeader+24+headers_file.NumberOfSections*40+12) = a;
}
//printf("%x\n",a);
//sections.VirtualAddress = sections.VirtualAddress+sections.VirtualSize;
*(int*)(start_new_image+headers_file.e_lfanew+headers_file.SizeOfOptionalHeader+24+headers_file.NumberOfSections*40+16) = (flen/0x1000+1)*0x1000;
//sections.SizeOfRawData = headers_file.FileAlignment;
*(int*)(start_new_image+headers_file.e_lfanew+headers_file.SizeOfOptionalHeader+24+headers_file.NumberOfSections*40+20) = sections.PointerToRawData+sections.SizeOfRawData;
if(sections.VirtualSize>sections.SizeOfRawData){
sections.VirtualAddress = a;}
else{
sections.VirtualAddress = a;
}
sections.PointerToRawData = sections.PointerToRawData+sections.SizeOfRawData;
sections.VirtualSize = (flen/0x1000+1)*0x1000;
sections.SizeOfRawData = (flen/0x1000+1)*0x1000;
}
addcode(start_new_image);
return start_new_image;
}
- 数据目录：
1、我们所了解的PE分为头和节，在每个节中，都包含了我们写的一些代码和数据，但还有一些非常重要
的信息是编译器替我们加到PE文件中的，这些信息可能存在在任何可以利用的地方。
2、这些信息之所以重要，是因为这些信息包含了诸如：
PE程序的图标在哪里？
用到了哪些系统提供的函数？
为其他的程序提供哪些函数？
3、编译器添加了这么多信息，那程序是如何找到这些信息的呢？
答案就是：数据目录
4、数据目录定位：
可选PE头最后一个成员，就是数据目录.一共有16个:
typedef struct _IMAGE_DATA_DIRECTORY {
DWORD VirtualAddress; //内存偏移
DWORD Size; //大小
} IMAGE_DATA_DIRECTORY, *PIMAGE_DATA_DIRECTORY;
#define IMAGE_NUMBEROF_DIRECTORY_ENTRIES 16
分别是：导出表、导入表、资源表、异常信息表、安全证书表、重定位表、调试信息表、版权所以表、全局指针表
TLS表、加载配置表、绑定导入表、IAT表、延迟导入表、COM信息表 最后一个保留未使用。
和程序运行时息息相关的表有：
- 导出表
1.数据目录项的第一个结构，就是导出表，其中的内存偏移 VirtualAddress指向导出表真正的位置
typedef struct _IMAGE_DATA_DIRECTORY {
DWORD VirtualAddress;
DWORD Size;
} IMAGE_DATA_DIRECTORY, *PIMAGE_DATA_DIRECTORY;
VirtualAddress 导出表的RVA
Size 导出表大小
2.导出表结构：
typedef struct _IMAGE_EXPORT_DIRECTORY {
DWORD Characteristics; // 未使用
DWORD TimeDateStamp; // 时间戳
WORD MajorVersion; // 未使用
WORD MinorVersion; // 未使用
DWORD Name; // 指向该导出表文件名字符串
DWORD Base; // 导出函数起始序号
DWORD NumberOfFunctions; // 所有导出函数的个数
DWORD NumberOfNames; // 以函数名字导出的函数个数
DWORD AddressOfFunctions; // 导出函数地址表RVA
DWORD AddressOfNames; // 导出函数名称表RVA
DWORD AddressOfNameOrdinals; // 导出函数序号表RVA
} IMAGE_EXPORT_DIRECTORY, *PIMAGE_EXPORT_DIRECTORY;
三个重要的结构：AddressOfFunctions、AddressOfNames、AddressOfNameOrdinals
3、AddressOfFunctions说明：
该表中元素宽度为4个字节
该表中存储所有导出函数的地址
该表中个数由NumberOfFunctions决定
该表项中的值是RVA, 加上ImageBase才是函数真正的地址
4、AddressOfNames说明：
该表中元素宽度为4个字节
该表中存储所有以名字导出函数的名字的RVA
该表项中的值是RVA, 指向函数真正的名称
5、AddressOfNameOrdinals
该表中元素宽度为2个字节
该表中存储的内容 + Base = 函数的导出序号
- 导入表
1.导入表结构：
typedef struct _IMAGE_IMPORT_DESCRIPTOR {
union {
DWORD Characteristics;
DWORD OriginalFirstThunk; //RVA 指向IMAGE_THUNK_DATA结构数组
};
DWORD TimeDateStamp; //时间戳
DWORD ForwarderChain;
DWORD Name; //RVA,指向dll名字，该名字已0结尾
DWORD FirstThunk; //RVA,指向IMAGE_THUNK_DATA结构数组
} IMAGE_IMPORT_DESCRIPTOR;
typedef IMAGE_IMPORT_DESCRIPTOR UNALIGNED *PIMAGE_IMPORT_DESCRIPTOR;
2.示意图：
- 重定位表
1.重定位表的定位：
数据目录项的第6个结构，就是重定位表.
typedef struct _IMAGE_DATA_DIRECTORY {
DWORD VirtualAddress;
DWORD Size;
} IMAGE_DATA_DIRECTORY, *PIMAGE_DATA_DIRECTORY;
2.重定位表的结构：
typedef struct _IMAGE_BASE_RELOCATION {
DWORD VirtualAddress;
DWORD SizeOfBlock;
} IMAGE_BASE_RELOCATION;
typedef IMAGE_BASE_RELOCATION ，* PIMAGE_BASE_RELOCATION;
3.解析说明：
1、通过IMAGE_DATA_DIRECTORY结构的VirtualAddress
属性 找到第一个IMAGE_BASE_RELOCATION
2、判断一共有几块数据：
最后一个结构的VirtualAddress与SizeOfBlock都为0
3、具体项 宽度：2字节
位于SizeOfBlock之后的数据
内存中的页大小是1000H 也就是说2的12次方 就可以表示
一个页内所有的偏移地址 具体项的宽度是16字节 高四位
代表类型：值为3 代表的是需要修改的数据 值为0代表的是
用于数据对齐的数据，可以不用修改.也就是说 我们只关注
高4位的值为3的就可以了.
4、VirtualAddress 宽度：4字节
当前这一个块的数据，每一个低12位的值+VirtualAddress 才是
真正需要修复的数据的RVA
真正的RVA = VirtualAddress + 具体项的低12位
5、SizeOfBlock 宽度：4字节
当前块的总大小
具体项的数量 = (SizeOfBlock - 8)/2
二、运用C语言、win32函数及上述知识写一个PE解析的图形界面
- 使用win32函数而不是QT或者MFC来构建图形界面，使我更加了解了底层的工作原理，有助于对图形界面的逆向分析
vc中的主界面
实际运行的主界面
vc中的PE查看器界面
选择程序进行PE查看（exe）
实际运行的PE查看界面（这里选择的exe是程序本身）
vc中的节表界面
实际运行的节表界面
vc中的目录界面
实际运行的目录界面
还有各种具体的目录信息界面，这里不做赘述。

三、加壳思路及代码实现
- 思路
1、获取Shell程序的路径
2、获取src程序的路径
3、将src程序读取到内存中，加密（我使用了最简单的异或，密钥是“4310”，可以随意更换加密方式）
4、在Shell程序中新增一个节，并将加密后的src程序追加到Shell程序的新增节中
5、加壳过程完毕
- 壳子程序思路
1、获取SHELL程序的路径
2、获取src的数据
(1) 定为到SHELL文件的最后一个节
(2) 将数据取出，并解密
3、拉伸PE
将解密后的PE文件在内存中拉伸，并存储到缓冲区中
4、以挂起方式运行Shell进程
(0) 以挂起形成创建Shell进程，并得到主线程的Context
(1) 卸载外壳程序的文件镜像(ZwUnmapViewOfSection)
(2) 在指定的位置(src的ImageBase)申请指定大小(src的SizeOfImage)的内存(VirtualAllocEx)
(3) 如果创建失败，查看src是否包含重定位表，如果包含重定位表，就在任意位置申请(src的SizeOfImage)
大小的内存，然后修复重定位表.
(4) 如果在指定位置申请内存失败，并且没有重定位表的数据，直接返回失败.
(5) 如果内存申请成功，将新的数据复制到内存中
(6) 修正运行环境的基址和入口地址
(7) 恢复主线程执行
- 壳子程序流程
1、读取主模块的数据
2、解密：得到原来的PE文件
3、以挂起的形式创建进程：CreateProcess ：要创建的进程在哪里？
要创建的进程，就是壳子本身！
4、获取外壳程序的Context,后面要用.
5、卸载外壳程序.
6、在指定的位置分配空间：位置就是src的ImageBase 大小就是Src的SizeOfImage
7、如果成功，将Src的PE文件拉伸 复制到该空间中
8、如果申请空间失败，但有重定位表：在任意位置申请空间，然后将PE文件拉伸、复制、修复重定位表。
9、如果第6步申请空间失败，并且还没有重定位表，直接返回：失败.
10、修改外壳程序的Context:
将Context的ImageBase 改成 Src的ImageBase
将Context的OPE 改成 Src的OEP
11、设置Context 并恢复主线程
12、终止外壳程序，解壳过程结束.
- 原理
这样对加壳后的程序进行分析，分析的是壳子程序本身，而不是原程序，达到了防止静态检测的目的，但是对动态检测效果甚微。

- 效果展示
在物理主机中，总是被360检测为病毒，此过程在虚拟中进行。我采用笔记本程序NOTEPAD.exe程序作为原程序，进行加壳
生成了加壳后的程序，命名为4310.exe
运用PE工具，与NOTEPAD.exe进行pe结构比对
可以看到pe结构根本不同，因为这里分析的是壳子程序的PE结构，但双击运行
运行的是壳子程序，但是壳子程序在4GB虚拟内存中，把自身卸载掉，然后换上存储在节中的原程序（此处就是NOTEPAD.exe），也就达到如此效果，如果把NOTEPAD.exe换成木马程序，就能实现文件免杀的效果。
四、总结
这个项目从刚开学就开始做了，中间停滞了一段时间（复习考研），导致后来继续的时候，一些模块丢失，不能把逆向进阶和加壳的程序代码加到PE工具图形界面中，有些遗憾，但是预期效果都达到了，下一步的学习就是向内核（0环）进阶。
