本文主要是介绍WindowsPE权威指南学习过程中的代码片段,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
第一个基础的HelloWorld
.386 .model flat,stdcall option casemap:none include windows.inc include user32.inc includelib user32.lib include kernel32.inc includelib kernel32.lib .data szText db 'HelloWorld',0 .code start: invoke MessageBox,NULL,offset szText,NULL,MB_OK invoke ExitProcess,NULL end start
调试观察栈的变化
.386 .model flat,stdcall option casemap:none include windows.inc include user32.inc includelib user32.lib include kernel32.inc includelib kernel32.lib .code _add proc a:word,b:word local @bl1:dword ret _add endp start: push 1 push 2 call _add add eax,1 end start
第二章的几个小工具
太长太长了,而且书中代码有一些过时的部分,所以也就跟着敲了一部分。

导入表值导入多个user32的函数,稍微修改了一下,按照原文禁止窗口就不好玩了。

1.def
EXPORTS AnimateOpen AnimateClose FadeInOpen FadeOutClose
编译链接:
ml -c -coff 1.asm link -subsystem:windows -DLL -def:1.def 1.obj
但是要在其他程序中使用这个dll,还需要编写inc文件
1.inc
AnimateOpen proto :dword AnimateClose proto :dword FadeInOpen proto :dword FadeOutClose proto :dword
后面的例子,使用上一个dll
.386 .model flat,stdcall option casemap:none include windows.inc include gdi32.inc includelib gdi32.lib include user32.inc includelib user32.lib include kernel32.inc includelib kernel32.lib include 1.inc includelib 1.lib .data? hInstance dd ? hWinMain dd ? .const szClassName db 'MyClass',0 szCaptionMain db '窗口特效演示',0 szText db '你好,认识我吗?^-^',0 .code _ProcWinMain proc uses ebx edi esi,hWnd,uMsg,wParam,lParam local @stPs:PAINTSTRUCT local @stRect:RECT local @hDc mov eax,uMsg .if eax==WM_PAINT invoke BeginPaint,hWnd,addr @stPs invoke DrawText,@hDc,addr szText,-1,\ addr @stRect,\ DT_SINGLELINE or DT_CENTER or DT_VCENTER invoke EndPaint,hWnd,addr @stPs .elseif eax==WM_CLOSE invoke FadeOutClose,hWinMain invoke DestroyWindow,hWinMain invoke PostQuitMessage,NULL .else invoke DefWindowProc,hWnd,uMsg,wParam,lParam ret .endif xor eax,eax ret _ProcWinMain endp _WinMain proc local @stWndClass:WNDCLASSEX local @stMsg:MSG invoke GetModuleHandle,NULL mov hInstance,eax invoke RtlZeroMemory,addr @stWndClass,sizeof @stWndClass invoke LoadCursor,0,IDC_ARROW mov @stWndClass.hCursor,eax push hInstance pop @stWndClass.hInstance mov @stWndClass.cbSize,sizeof WNDCLASSEX mov @stWndClass.style,CS_HREDRAW or CS_VREDRAW mov @stWndClass.lpfnWndProc,offset _ProcWinMain mov @stWndClass.hbrBackground,COLOR_WINDOW + 1 mov @stWndClass.lpszClassName,offset szClassName invoke RegisterClassEx,addr @stWndClass invoke CreateWindowEx,WS_EX_CLIENTEDGE,\ offset szClassName,offset szCaptionMain,\ WS_OVERLAPPEDWINDOW,\ 100,100,600,400,\ NULL,NULL,hInstance,NULL mov hWinMain,eax invoke FadeInOpen,hWinMain ;invoke ShowWindow,hWinMain,SW_SHOWNORMAL invoke UpdateWindow,hWinMain .while TRUE invoke GetMessage,addr @stMsg,NULL,0,0 .break .if eax == 0 invoke TranslateMessage,addr @stMsg invoke DispatchMessage,addr @stMsg .endw ret _WinMain endp start: call _WinMain invoke ExitProcess,NULL end start
延迟导入:
.386 .model flat,stdcall option casemap:none include windows.inc include user32.inc includelib user32.lib include kernel32.inc includelib kernel32.lib include 7.inc includelib 7.lib include delayimp.inc includelib delayimp.lib .data dwFlag dd 1 szText db 'HelloWorldPE',0 .code start: mov eax,dwFlag .if eax==0 invoke AnimateOpen,NULL .endif invoke MessageBox,NULL,offset szText,NULL,MB_OK invoke ExitProcess,NULL end start
代码没问题,但是win10下的masm32链接就报错,所以想学习这个延迟导入,直接VS写个代码,然后配置里面添加延迟导入的dll就可以了。
第9章的使用TLS多线程的例子。

不带TLS的多线程例子
.386 .model flat,stdcall option casemap:none include windows.inc include user32.inc includelib user32.lib include kernel32.inc includelib kernel32.lib MAX_THREAD_COUNT equ 4 .data hTlsIndex dd ? dwThreadID dd ? hThreadID dd MAX_THREAD_COUNT dup(0) dwCount dd ? szBuffer db 500 dup(0) szOut1 db 'xc %d terminated,use %d ms.',0 .code _tFun proc uses ebx ecx edx esi edi,lParam local @dwCount local @dwStart local @dwEnd local @tID pushad invoke GetTickCount mov @dwStart,eax mov @dwCount,1000*10000 mov ecx,@dwCount .while ecx>0 dec @dwCount dec ecx .endw invoke GetCurrentThreadId mov @tID,eax invoke GetTickCount mov @dwEnd,eax mov eax,@dwStart sub @dwEnd,eax invoke wsprintf,addr szBuffer,addr szOut1,@tID,@dwEnd invoke MessageBox,NULL,addr szBuffer,NULL,MB_OK popad ret _tFun endp start: mov dwCount,MAX_THREAD_COUNT mov edi,offset hThreadID .while dwCount>0 invoke CreateThread,NULL,0,offset _tFun,NULL,NULL,addr dwThreadID mov dword ptr [edi],eax add edi,4 dec dwCount .endw mov dwCount,MAX_THREAD_COUNT mov edi,offset hThreadID .while dwCount>0 mov eax,dword ptr [edi] mov dwThreadID,eax push edi invoke WaitForSingleObject,dwThreadID,INFINITE invoke CloseHandle,dwThreadID pop edi add edi,4 dec dwCount .endw invoke ExitProcess,NULL end start
TLS回调函数的例子
.386 .model flat,stdcall option casemap:none include windows.inc include user32.inc includelib user32.lib include kernel32.inc includelib kernel32.lib .data szText db 'HelloWorldPE',0,0,0,0 TLS_DIRR dd offset Tls1 dd offset Tls2 dd offset Tls3 dd offset TlsCallBack dd 0 dd 0 Tls1 dd 0 Tls2 dd 0 Tls3 dd 0 TlsCallBack dd offset TLS dd 0 dd 0 .data? TLSCalled db ? .code start: invoke ExitProcess,NULL RET TLS: cmp byte ptr [TLSCalled],1 je @exit mov byte ptr [TLSCalled],1 invoke MessageBox,NULL,addr szText,NULL,MB_OK @exit: RET end start
需要注意的是,这里构造了数据目录表里面线程本地存储表的数据,需要自己修改exe的字节文件,让那个表指向代码段的数据。详情可见本人线程本地存储记录。
第11章,获取kernel32.dll地址(一)
.386 .model flat,stdcall option casemap:none include windows.inc include user32.inc includelib user32.lib include kernel32.inc includelib kernel32.lib .data szText db 'kernel32.dll的基地址为%08x',0 szOut db '%08x',0dh,0ah,0 szBuffer db 256 dup(0) .code start: call loc0 db 'GetProcAddress',0 loc0: pop edx push edx mov ebx,7ffe0000h ;mov ebx,75950000h loc1: cmp dword ptr [ebx],905A4Dh JE loc2 loc5: sub ebx,00010000h pushad invoke IsBadReadPtr,ebx,2 .if eax popad jmp loc5 .endif popad jmp loc1 loc2: mov esi,dword ptr [ebx+3ch] add esi,ebx mov esi,dword ptr [esi+78h] nop .if esi==0 jmp loc5 .endif add esi,ebx mov edi,dword ptr [esi+20h] add edi,ebx mov ecx,dword ptr [esi+18h] push esi xor eax,eax loc3: push edi push ecx mov edi,dword ptr [edi] add edi,ebx mov esi,edx xor ecx,ecx mov cl,0eh repe cmpsb pop ecx pop edi je loc4 add edi,4 inc eax loop loc3 jmp loc5 loc4: invoke wsprintf,addr szBuffer,addr szText,ebx invoke MessageBox,NULL,addr szBuffer,NULL,MB_OK ret end start
这里有坑,它写的地址太高了,不属于此进程,使用isbadreadptr就会抛出异常。个人认为,还不如直接查看栈顶地址,然后以10000H向下取整。。。因为执行到main的时候,是从kernel32.dll跳过来的。
(二)
.386 .model flat,stdcall option casemap:none include windows.inc include kernel32.inc includelib kernel32.lib include user32.inc includelib user32.lib .data szText db 'ksernel32.dll %08x',0 szOut db '%08x',0dh,0ah,0 szBuffer db 256 dup(0) .code start: assume fs:nothing mov eax,fs:[0] inc eax loc1: dec eax mov esi,eax mov eax,[eax] inc eax jne loc1 lodsd lodsd xor ax,ax jmp loc3 loc2: sub eax,10000h loc3: cmp dword ptr [eax],905A4Dh jne loc2 invoke wsprintf,addr szBuffer,addr szText,eax invoke MessageBox,NULL,addr szBuffer,NULL,MB_OK invoke ExitProcess,NULL ret end start
本人对此也不太熟悉,不过能确定的是,在win10上,运行结果是错的,不是kernel32.dll的地址。建议合并一和二。把一里面那个太高的地址改成二获得的地址就好了。
(三)
.386 .model flat,stdcall option casemap:none include windows.inc include kernel32.inc includelib kernel32.lib include user32.inc includelib user32.lib .data szText db 'ksernel32.dll %08x',0 szOut db '%08x',0dh,0ah,0 szBuffer db 256 dup(0) .code start: assume fs:nothing mov eax,fs:[30h] mov eax,[eax+0ch] mov esi,[eax+1ch] lodsd mov eax,[eax];这一句是win7/win10需要添加的,原文没有,运行结果不是对的 mov eax,[eax+8] invoke wsprintf,addr szBuffer,addr szText,eax invoke MessageBox,NULL,addr szBuffer,NULL,MB_OK invoke ExitProcess,NULL ret end start
