OEPCODEFIVE: THEAD =
($55, $8B, $EC, $6A, $FF, $68, $00, $00, $00, $00, $68, $00, $00, $00, $00, $64,
$A1, $00, $00, $00, $00, $50, $64, $89, $25, $00, $00, $00, $00, $83, $EC, $68,
$53, $56, $57, $58, $58, $58, $83, $C4, $68, $58, $67, $64, $A3, $00, $00, $58,

1.直接将入口地址赋给寄存器eax,然后jmp eax
0046902A B8 304A4500 mov eax,Project1.00454A30
0046902F FFE0 jmp eax
00469031 90 nop
2. 直接跳转到入口地址
00469124 - E9 07B9FEFF jmp Project1.00454A30
两种效果实际上是一样的,但我们为了方便修改花指令跳转到原来的入口地址，通常取得原
pe header的AddressOfEntryPoint,然后给寄存器eax保存改值，所以第二种方法就不太方便，
所以一般采用第一种方法，JMPOFF为花指令代码到跳转指令的偏移，如对Visual C++的花指令
JMPOFF=54,其后免跟的是原入口地址，可以随便填写，程序加花指令是会自动修改，一般可以
默认设为00104000(即00401000).
通过汇编修改花指令跳转原入口地址的语句:
asm //这里说明一下，这是嵌入的汇编代码,寄存器—CPU暂时储存数据的东西，比内存更快，以提高效率
PUSHAD
LEA eax, OEPCODE //将OEPCODE的地址交给寄存器
ADD eax, JMPOFF //添加JMPOFF值给寄存器
MOV edx, AddressOfEntryPoint //转移指令，相当于付值语句，左边给右边
MOV DWORD ptr [eax], edx //同上
POPAD

{Tstream中定义的虚方法有四个：
1、Read:此方法实现将数据从流中读出。函数原形为：
Function Read(var Buffer;Count:Longint):Longint;virtual;abstract;
参数Buffer为数据读出时放置的缓冲区，Count为需要读出的数据的字节数，该方法返回值为实际读出的字节数，它可以小于或等于Count中指定的值。
2、Write:此方法实现将数据写入流中。函数原形为：
Function Write(var Buffer;Count:Longint):Longint;virtual;abstract;
参数Buffer为将要写入流中的数据的缓冲区，Count为数据的长度字节数，该方法返回值为实际写入流中的字节数。
3、Seek:此方法实现流中读取指针的移动。函数原形为：
Function Seek(Offset:Longint;Origint:Word):Longint;virtual;abstract;
参数Offset为偏移字节数,参数Origint指出Offset的实际意义，其可能的取值如下：
soFromBeginning:Offset为移动后指针距离数据开始的位置。此时Offset必须大于或者等于零。
soFromCurrent:Offset为移动后指针与当前指针的相对位置。
soFromEnd:Offset为移动后指针距离数据结束的位置。此时Offset必须小于或者等于零。该方法返回值为移动后指针的位置。
4、Setsize:此方法实现改变数据的大小。函数原形为：
Function Setsize(NewSize:Longint);virtual; }
//将指针偏移量放到文件头部
fs.Seek(0, soFromBeginning);
//读取DOS头信息
fs.Read(DOSHEADER, sizeof(DOSHEADER));
//DOS MZ header 又命名为 IMAGE_DOS_HEADER.。其中只有两个域比较重要:
//e_magic 包含字符串"MZ"，e_lfanew 包含PE header在文件中的偏移量。
//将指针移到PE header在文件中的偏移量
fs.Seek(DOSHEADER._lfanew, soFromBeginning);
//读取PE header头信息
fs.Read(PEHEADER, sizeOf(PEHEADER));
//PEHEADER.FileHeader.NumberOfSections:文件的节数目。如果我们要在文件中增加或删除一个节，就需要修改这个值。
//将指针移到节表在当前位置的相对偏移量
fs.Seek(sizeOf(SectionHeader) *
(PEHEADER.FileHeader.NumberOfSections - 1), soFromCurrent);
//读取节表的信息
fs.Read(SectionHeader, sizeof(IMAGE_SECTION_HEADER));
//节名长不超过8字节。记住节名仅仅是个标记而已,我们选择任何名字甚至空着也行
{ MySectionHeader.Name[0] := ord('F');
MySectionHeader.Name[1] := ord('i');
MySectionHeader.Name[2] := ord('7');

//则本域值为0x400，表示本节是0x400字节长）。
//FileAlignment 文件中节对齐的粒度。例如，如果该值是(200h),，那么每节的起始地址必须是512的倍数。

{PE装载器的工作:
1.读取 IMAGE_FILE_HEADER 的 NumberOfSections域，知道文件的节数目。
2.SizeOfHeaders 域值作为节表的文件偏移量，并以此定位节表。
3.遍历整个结构数组检查各成员值。
4.对于每个结构，我们读取PointerToRawData域值并定位到该文件偏移量。然后再读取SizeOfRawData域值来决定
映射内存的字节数。将VirtualAddress域值加上ImageBase域值等于节起始的虚拟地址。然后就准备把节映射进内存，
并根据Characteristics域值设置属性。
5.遍历整个数组，直至所有节都已处理完毕。
注意我们并没有使用节名: 这其实并不重要。}

1.直接将入口地址赋给寄存器eax,然后jmp eax
0046902A B8 304A4500 mov eax,Project1.00454A30
0046902F FFE0 jmp eax
00469031 90 nop
2. 直接跳转到入口地址
00469124 - E9 07B9FEFF jmp Project1.00454A30
两种效果实际上是一样的,但我们为了方便修改花指令跳转到原来的入口地址，通常取得原
pe header的AddressOfEntryPoint,然后给寄存器eax保存改值，所以第二种方法就不太方便，
所以一般采用第一种方法，JMPOFF为花指令代码到跳转指令的偏移，如对Visual C++的花指令
JMPOFF=54,其后免跟的是原入口地址，可以随便填写，程序加花指令是会自动修改，一般可以
默认设为00104000(即00401000).
通过汇编修改花指令跳转原入口地址的语句:
asm //这里说明一下，这是嵌入的汇编代码,寄存器—CPU暂时储存数据的东西，比内存更快，以提高效率
PUSHAD
LEA eax, OEPCODE //将OEPCODE的地址交给寄存器
ADD eax, JMPOFF //添加JMPOFF值给寄存器
MOV edx, AddressOfEntryPoint //转移指令，相当于付值语句，左边给右边
MOV DWORD ptr [eax], edx //同上

{Tstream中定义的虚方法有四个：
1、Read:此方法实现将数据从流中读出。函数原形为：
Function Read(var Buffer;Count:Longint):Longint;virtual;abstract;
参数Buffer为数据读出时放置的缓冲区，Count为需要读出的数据的字节数，该方法返回值为实际读出的字节数，它可以小于或等于Count中指定的值。
2、Write:此方法实现将数据写入流中。函数原形为：
Function Write(var Buffer;Count:Longint):Longint;virtual;abstract;
参数Buffer为将要写入流中的数据的缓冲区，Count为数据的长度字节数，该方法返回值为实际写入流中的字节数。
3、Seek:此方法实现流中读取指针的移动。函数原形为：
Function Seek(Offset:Longint;Origint:Word):Longint;virtual;abstract;
参数Offset为偏移字节数,参数Origint指出Offset的实际意义，其可能的取值如下：
soFromBeginning:Offset为移动后指针距离数据开始的位置。此时Offset必须大于或者等于零。
soFromCurrent:Offset为移动后指针与当前指针的相对位置。
soFromEnd:Offset为移动后指针距离数据结束的位置。此时Offset必须小于或者等于零。该方法返回值为移动后指针的位置。
4、Setsize:此方法实现改变数据的大小。函数原形为：
Function Setsize(NewSize:Longint);virtual; }
//将指针偏移量放到文件头部
fs.Seek(0, soFromBeginning);
//读取DOS头信息
fs.Read(DOSHEADER, sizeof(DOSHEADER));
//DOS MZ header 又命名为 IMAGE_DOS_HEADER.。其中只有两个域比较重要:
//e_magic 包含字符串"MZ"，e_lfanew 包含PE header在文件中的偏移量。
//将指针移到PE header在文件中的偏移量
fs.Seek(DOSHEADER._lfanew, soFromBeginning);
//读取PE header头信息
fs.Read(PEHEADER, sizeOf(PEHEADER));
//PEHEADER.FileHeader.NumberOfSections:文件的节数目。如果我们要在文件中增加或删除一个节，就需要修改这个值。
//将指针移到节表在当前位置的相对偏移量
fs.Seek(sizeOf(SectionHeader) *
(PEHEADER.FileHeader.NumberOfSections - 1), soFromCurrent);
//读取节表的信息
fs.Read(SectionHeader, sizeof(IMAGE_SECTION_HEADER));
//节名长不超过8字节。记住节名仅仅是个标记而已,我们选择任何名字甚至空着也行
{ MySectionHeader.Name[0] := ord('F');
MySectionHeader.Name[1] := ord('i');
MySectionHeader.Name[2] := ord('7');
MySectionHeader.Name[3] := ord('k');
MySectionHeader.Name[4] := ord('e');
MySectionHeader.Name[5] := 0;
MySectionHeader.Name[6] := 0;
MySectionHeader.Name[7] := 0; }
for i:=0 to 7 do
begin
MySectionHeader.Name[i] :=0;
if i<length(MySection) then
MySectionHeader.Name[i] :=Ord(MySection[i+1]);
end;
//VirtualAddress 本节的RVA（相对虚拟地址）。PE装载器将节映射至内存时会读取本值，因此如果域值是1000h，
//而PE文件装在地址400000h处，那么本节就被载到401000h。
//SizeOfImage 内存中整个PE映像体的尺寸。它是所有头和节经过节对齐处理后的大小。
MySectionHeader.VirtualAddress := PEHEADER.OptionalHeader.SizeOfImage;
//节的大小 $200十六进制 ＝ 512字节 最好大于 512 不然可能会出错
//MySectionHeader.Misc.VirtualSize := $200;
MySectionHeader.Misc.VirtualSize := SecSize; //StrToInt(IntToHex(SecSize,sizeof(SecSize)));
//SizeOfRawData 经过文件对齐处理后节尺寸，PE装载器提取本域值了解需映射入内存的节字节数。
//（译者注: 假设一个文件的文件对齐尺寸是0x200，如果前面的 VirtualSize域指示本节长度是0x388字节，
//则本域值为0x400，表示本节是0x400字节长）。
//FileAlignment 文件中节对齐的粒度。例如，如果该值是(200h),，那么每节的起始地址必须是512的倍数。
//若第一节从文件偏移量200h开始且大小是10个字节，则下一节必定位于偏移量400h:
//即使偏移量512和1024之间还有很多空间没被使用/定义。
MySectionHeader.SizeOfRawData := (MySectionHeader.VirtualAddress div
PEHEADER.OptionalHeader.FileAlignment + 1) * PEHEADER.OptionalHeader.FileAlignment -
PEHEADER.OptionalHeader.SizeOfImage;
//这是节基于文件的偏移量，PE装载器通过本域值找到节数据在文件中的位置。
MySectionHeader.PointerToRawData :=
SectionHeader.SizeOfRawData + SectionHeader.PointerToRawData;
//包含标记以指示节属性，比如节是否含有可执行代码、初始化数据、未初始数据，是否可写、可读等。
MySectionHeader.Characteristics := $E0000020;
{PE装载器的工作:
1.读取 IMAGE_FILE_HEADER 的 NumberOfSections域，知道文件的节数目。
2.SizeOfHeaders 域值作为节表的文件偏移量，并以此定位节表。
3.遍历整个结构数组检查各成员值。
4.对于每个结构，我们读取PointerToRawData域值并定位到该文件偏移量。然后再读取SizeOfRawData域值来决定
映射内存的字节数。将VirtualAddress域值加上ImageBase域值等于节起始的虚拟地址。然后就准备把节映射进内存，
并根据Characteristics域值设置属性。
5.遍历整个数组，直至所有节都已处理完毕。
注意我们并没有使用节名: 这其实并不重要。}
