在winnt.h头文件中有定义，32位win程序的PE结构和64位win程序的有所不同，但区别不大。
☀️ PE文件的整体结构
☀️ PE文件的两种状态
红色表示更多的空白
☀️ RVA与FOA转化
- 如果文件对齐和文件对齐相同，则
FOA==RVA。 - 得到RVA的值:内存地址 – ImageBase
- 判断RVA是否位于PE头中，如果是:
FOA==RVA - 判断RVA位于哪个节:
RVA>=节.VirtualAddressRVA<=节.VirtualAddress +当前节内存对齐后的大小差值=RVA - 节.VirtualAddress
☀️ 空白区添加代码
1️⃣ 构造要写入的代码
【注】call指令后面的硬编码数据 = 要跳转的地址 - 指令当前的地址 - 5
2️⃣ 在PE的空白区构造一段代码（比如节表之间的空间）
3️⃣ 修改入口地址为新增代码
4️⃣ 新增代码执行后，跳回入口地址
☀️ 扩大节的步骤
1️⃣ 分配一块新的空间，大小为S
2️⃣ 将最后一个节的SizeOfRawData和VirtualSize改成NN =(SizeOfRawData或者VirtualSize内存对齐后的值)+S
3️⃣ 修改SizeOflmage大小
☀️ 新增节的步骤
1️⃣ 判断是否有足够的空间，可以添加一个节表
2️⃣ 在节表中新增一个成员
3️⃣ 修改PE头中节的数量
4️⃣ 修改sizeOflmage的大小
5️⃣ 再原有数据的最后，新增一个节的数据(内存对齐的整数倍)
6️⃣ 修正新增节表的属性
☀️ 合并节的步骤
1️⃣ 按照内存对齐展开
2️⃣ 将第一个节的内存大小、文件大小改成一样Max = SizeOfRawData>VirtualSize?SizeOfRawData:VirtualSizeSizeOfRawData = VirtualSize = 最后一个节的VirtualAddress + Max - SizeOfHeaders内存对齐后的大小
3️⃣ 将第一个节的属性改为包含所有节的属性.
4️⃣ 修改节的数量.
☀️ IMAGE_DOS_HEADER（64个字节）
这个结构体是给16位dos程序看的（e_magic 和 e_lfanew 例外）
typedef struct _IMAGE_DOS_HEADER { // DOS .EXE header
WORD e_magic; // Magic number
WORD e_cblp; // Bytes on last page of file
WORD e_cp; // Pages in file
WORD e_crlc; // Relocations
WORD e_cparhdr; // Size of header in paragraphs
WORD e_minalloc; // Minimum extra paragraphs needed
WORD e_maxalloc; // Maximum extra paragraphs needed
WORD e_ss; // Initial (relative) SS value
WORD e_sp; // Initial SP value
WORD e_csum; // Checksum
WORD e_ip; // Initial IP value
WORD e_cs; // Initial (relative) CS value
WORD e_lfarlc; // File address of relocation table
WORD e_ovno; // Overlay number
WORD e_res[4]; // Reserved words
WORD e_oemid; // OEM identifier (for e_oeminfo)
WORD e_oeminfo; // OEM information; e_oemid specific
WORD e_res2[10]; // Reserved words
LONG e_lfanew; // File address of new exe header
} IMAGE_DOS_HEADER, *PIMAGE_DOS_HEADER;
1️⃣ e_magic PE指纹的第一部分，值为IMAGE_DOS_SIGNATURE/0x5A4D/"MZ"。
2️⃣ e_lfanew 指向PE头的偏移。
☀️ Dos Stub（Dos块）
是编译器生成的，没有啥用处，可以随意修改。
☀️ IMAGE_NT_HEADERS
typedef struct _IMAGE_NT_HEADERS {
DWORD Signature;
IMAGE_FILE_HEADER FileHeader;
IMAGE_OPTIONAL_HEADER32 OptionalHeader;
} IMAGE_NT_HEADERS32, *PIMAGE_NT_HEADERS32;
typedef struct _IMAGE_NT_HEADERS64 {
DWORD Signature;
IMAGE_FILE_HEADER FileHeader;
IMAGE_OPTIONAL_HEADER64 OptionalHeader;
} IMAGE_NT_HEADERS64, *PIMAGE_NT_HEADERS64;
1️⃣ Signature PE指纹的第二部分，值为IMAGE_NT_SIGNATURE/0x00004550/"PE"。
2️⃣ FileHeader 标准PE头，大小为20个字节，可以通过IMAGE_SIZEOF_FILE_HEADER宏获取。
3️⃣ OptionalHeader 扩展PE头。
☀️ IMAGE_FILE_HEADER
typedef struct _IMAGE_FILE_HEADER {
WORD Machine;
WORD NumberOfSections;
DWORD TimeDateStamp;
DWORD PointerToSymbolTable;
DWORD NumberOfSymbols;
WORD SizeOfOptionalHeader;
WORD Characteristics;
} IMAGE_FILE_HEADER, *PIMAGE_FILE_HEADER;

☀️ IMAGE_DATA_DIRECTORY
typedef struct _IMAGE_DATA_DIRECTORY {
DWORD VirtualAddress;
DWORD Size;
} IMAGE_DATA_DIRECTORY, *PIMAGE_DATA_DIRECTORY;
1️⃣ VirtualAddress 表在内存的RVA。
2️⃣ Size 表的大小，是指IMAGE_EXPORT_DIRECTORY结构体和其使用的所有数据之和，该值不会影响程序的运行。
☀️ IMAGE_EXPORT_DIRECTORY
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的辅助性信息

DWORD NumberOfNames; //以函数名字导出的函数个数
DWORD AddressOfFunctions; // RVA from base of image
DWORD AddressOfNames; // RVA from base of image
DWORD AddressOfNameOrdinals; // RVA from base of image
} IMAGE_EXPORT_DIRECTORY, *PIMAGE_EXPORT_DIRECTORY;
1️⃣ AddressOfFunctions 指向的表的成员的大小是4个字节。
2️⃣ AddressOfNames 指向的表的成员每一个以\'\0\'结束，以字符排序来进行。
3️⃣ AddressOfNameOrdinals 指向的表是给AddressOfNames看的，每一个对应在AddressOfFunctions的索引位置。
☀️ IMAGE_IMPORT_DESCRIPTOR（大小为20个字节）
这结构体一个挨着一个，以空结构体为结尾（内容全为0的
IMAGE_IMPORT_DESCRIPTOR）。
typedef struct _IMAGE_IMPORT_DESCRIPTOR {
union {
DWORD Characteristics; // 0 for terminating null import descriptor
DWORD OriginalFirstThunk; // RVA to original unbound IAT (PIMAGE_THUNK_DATA)
} DUMMYUNIONNAME;
DWORD TimeDateStamp; //时间戳
DWORD ForwarderChain; //不使用
DWORD Name; //指向Ascii字符串
DWORD FirstThunk; // RVA to IAT (if bound this IAT has actual addresses)
} IMAGE_IMPORT_DESCRIPTOR;
typedef IMAGE_IMPORT_DESCRIPTOR UNALIGNED *PIMAGE_IMPORT_DESCRIPTOR;
0️⃣ 图解OriginalFirstThunk
☀️ IMAGE_THUNK_DATA
typedef struct _IMAGE_THUNK_DATA32 {
union {
DWORD ForwarderString; // PBYTE
DWORD Function; // PDWORD
DWORD Ordinal;

typedef struct _IMAGE_THUNK_DATA64 {
union {
ULONGLONG ForwarderString; // PBYTE
ULONGLONG Function; // PDWORD
ULONGLONG Ordinal;
ULONGLONG AddressOfData; // PIMAGE_IMPORT_BY_NAME
} u1;
} IMAGE_THUNK_DATA64;
typedef IMAGE_THUNK_DATA64 * PIMAGE_THUNK_DATA64;
☀️ IMAGE_IMPORT_BY_NAME
typedef struct _IMAGE_IMPORT_BY_NAME {
WORD Hint;
CHAR Name[1];
} IMAGE_IMPORT_BY_NAME, *PIMAGE_IMPORT_BY_NAME;
☀️ IAT与INT
- PE加载前
- PE加载后
☀️ IMAGE_BASE_RELOCATION (重定位表)
typedef struct _IMAGE_BASE_RELOCATION {
DWORD VirtualAddress;
DWORD SizeOfBlock;
// WORD TypeOffset[1];
} IMAGE_BASE_RELOCATION;
typedef IMAGE_BASE_RELOCATION UNALIGNED * PIMAGE_BASE_RELOCATION;
☀️ 重定位表说明
若一个
DWORD中的高4位为3，即为0011，则VirtualAddress + 其低12位为即为要修复的地址。
