【详细过程】
今天拿到PcShare远程控制会员版本20070826，看看说明

一、加了插默认浏览器的功能

二、重新修改了文件下载,一目了然,肉机不上线也可以管理。

三、加了窗口管理的功能、

四、加了群发消息的功能

五、加了强制肉机访问网页的功能

六、增加代理(不完善测试阶段)

七、增加了记录系统登录密码功能
看着看着 就想破解，说干就干，不管是不是菜鸟，还是先查壳把，
  
用PEID查壳：
 Themida/WinLicense V1.8.2.0 +  -> Oreans Technologies   * Sign.By.fly *
如果你的查不到，可以下载最新的特征库

由于是Themida壳，1.9版本的后反OD的插件，只能用工具隐藏，PEID分辨不是很好，所以干脆就用HideToolz.exe 把OD隐藏起来

在HideToolz.exe里添加上你的OD的目录，在隐藏选项里选上：
Hide process
Protect process
Hide windows
Protect form windows

Anti-anti debug
Auto Start

设置好后打开OD，

1、设置OllyDBG忽略所有异常选项。
2、用HideOD插件:
勾选Auto Run HideOD、HideNtdebugBit。
勾选ZwQueryInformationProcess-->method2。

OD载入后，到这里：

00556014 P>  B8 00000000                       mov eax,0
00556019     60                                pushad

0055604C     33FF                              xor edi,edi                           ; ntdll.7C930738

接着运行okdodo大侠的Themida脚本后：

运行完成后有提示：
脚本执行完毕，请注意OEP是否被偷代码！

点确定，来到这里：

00422C05     50                                push eax
00422C06     64:8925 00000000                  mov dword ptr fs:[0],esp

00422C23     59                                pop ecx                               ; PcShare.00422D5A
00422C24     830D 34EA4900 FF                  or dword ptr ds:[49EA34],FFFFFFFF

被偷了OEP。

拿一个VC++的程序来参考下：

00401F10 D>  55                                push ebp
00401F11     8BEC                              mov ebp,esp
00401F13     6A FF                             push -1
00401F15     68 E8394000                       push 4039E8
00401F1A     68 96204000                       push 402096
00401F1F     64:A1 00000000                    mov eax,dword ptr fs:[0]
00401F25     50                                push eax
00401F26     64:8925 00000000                  mov dword ptr fs:[0],esp
00401F2D     83EC 68                           sub esp,68
00401F30     53                                push ebx
00401F31     56                                push esi
00401F32     57                                push edi                              ; ntdll.7C930738
00401F33     8965 E8                           mov dword ptr ss:[ebp-18],esp
00401F36     33DB                              xor ebx,ebx
00401F38     895D FC                           mov dword ptr ss:[ebp-4],ebx
00401F3B     6A 02                             push 2
00401F3D     FF15 4C334000                     call dword ptr ds:[40334C]            ; msvcrt.__set_app_type
00401F43     59                                pop ecx                               ; kernel32.7C816FD7
00401F44     830D 6C514000 FF                  or dword ptr ds:[40516C],FFFFFFFF
00401F4B     830D 70514000 FF                  or dword ptr ds:[405170],FFFFFFFF
00401F52     FF15 48334000                     call dword ptr ds:[403348]            ; msvcrt.__p__fmode


为了防止代码混淆，点分析代码，向上看 ：

00422BEA    .  C3                              retn
00422BEB    >  E9 70010000                     jmp 00422D60                          ;  jmp to msvcrt.terminate

00422C01    .  4C                              dec esp
00422C02    .  014E 2B                         add dword ptr ds:[esi+2B],ecx
00422C05    .  50                              push eax
00422C06    .  64:8925 00000000                mov dword ptr fs:[0],esp
00422C0D    .  83EC 68                         sub esp,68
00422C10    .  53                              push ebx
00422C11    .  56                              push esi                              ;  PcShare.0067B539
00422C12    .  57                              push edi
00422C13    .  8965 E8                         mov dword ptr ss:[ebp-18],esp
00422C16    .  33DB                            xor ebx,ebx
00422C18    .  895D FC                         mov dword ptr ss:[ebp-4],ebx
00422C1B    .  6A 02                           push 2
00422C1D    .  FF15 4C0D4800                   call dword ptr ds:[480D4C]            ;  msvcrt.__set_app_type


确定OEP：00422BF0

并补上OEP：

00422BF0       55                              push ebp
00422BF1       8BEC                            mov ebp,esp
00422BF3       6A FF                           push -1
00422BF5       68 E8394000                     push 4039E8-------------------------①
00422BFA       68 96204000                     push 402096-------------------------②
00422BFF       64:A1 00000000                  mov eax,dword ptr fs:[0]
00422C05    .  50                              push eax
00422C06    .  64:8925 00000000                mov dword ptr fs:[0],esp
00422C0D    .  83EC 68                         sub esp,68
00422C10    .  53                              push ebx
00422C11    .  56                              push esi                              ;  PcShare.0067B539
00422C12    .  57                              push edi
00422C13    .  8965 E8                         mov dword ptr ss:[ebp-18],esp
00422C16    .  33DB                            xor ebx,ebx
00422C18    .  895D FC                         mov dword ptr ss:[ebp-4],ebx
00422C1B    .  6A 02                           push 2

其中①和②处的数据可以看考堆栈里的数据

在堆栈里找到：

④处的数据就是①，③处的数据就是②

补好OEP后 把EIP指针改到OEP处 用LordPE_fix.EXE脱壳

打开ImportREC 填上OEP后自动查找IAT，获取函数输入表 如果有无效的就剪切掉。
到此脱壳完成，
PEID 查壳：Microsoft Visual C++ 6.0  脱壳后3.85 MB 
运行程序，程序有时候提示操作系统错误，原因我不是很清楚，用OD载入 F9运行，

找到出错的地方 修改下跳转就可以了，不过后来没修改的也可以运行了。
