运行后连续释放以下文件并运行：
"C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\T200645150560000027841\BigFoot.exe"
"C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\T200646380243000028112\BigFoot.exe"
"C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\T200647210381000028253\BigFoot.exe"
其中第一个是正常的大脚程序，后面的两个均是捆绑的恶意程序。
第一个恶意程序（第二个exe）较小：41KB，MD5：c0097ebdfca5250cc18c6888202ed154
第二个恶意程序（第三个exe）较大：232KB，MD5：6c20ad3c3023f26af774d4b5dbecdb0d
首先分析第二个恶意程序：
解压自身资源段中的代码，以覆盖的方式写入系统dll"C:\WINDOWS\system32\msxmlfilta.dll"中，创建注册表：

这个不知道是不是BHO，还是类似的东西？
覆写后的msxmlfilta.dll文件MD5：39d40d074eb693ca06ca35e435f29d9b，发现里面有以下字符串：
http://www.go2easy.com/iso/
http://www.sogou.com/features/ip.jsp
所在位置：北京
搜索了下，找到一篇文章：
ie7 ie8地址栏搜索被劫持到百度联盟:
http://www.fh.net.cn/home-space-uid-726-do-blog-id-4375.html
看来分析于此类似，说是浏览器的搜索劫持，详细请查看原文链接。里面的两个网址，一个是“Windows加密大师”的，一个是搜狗的，看来冠冕堂皇的背后却在悄悄地做着流氓的勾当。
----------------------------------------------分割线-----------------------------------------
下面分析第一个恶意程序，较小的那个，也是比较难分析的。
该exe遍历查找名为“.Wpack”的节，经过解密处理。获取当前进程路径并以挂起的方式创建一个新的进程，然后将上面解密后的代码写到新进程的内存空间，
然后唤醒进程。
这个过程不是很好分析，为此我写了一个api跟踪的dll来监视api调用的流程，以下是输出信息：

C:\WINDOWS\system32\wksbqizm.dll
C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\1.tmp.bat
创建的注册表：

{B38E77C6-E3E1-4b0f-BC51-6A8352868C4C} :C:\WINDOWS\system32\wksbqizm.dll
某次截获的"C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\1.tmp.bat"文件内容：
:try
del "C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\dsad11.exe"
if exist "C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\dsad11.exe" goto try
del %0
是为了实现自删除的。
下面主要wksbqizm.dll，这个dll的防静态分析做得很好，OD搜索不到任何字符串，字符串全部用双字一组组写入。
如果是在"verclsid.exe"进程中就安装钩子，0006F598 0006F6A8 ASCII "verclsid.exe"。
10003EBE A1 A4880010 mov eax,dword ptr ds:[100088A4]
10003EC3 8B35 B4600010 mov esi,dword ptr ds:[<&USER32.SetWindowsHookExA>] ; USER32.SetWindowsHookExA
10003EC9 6A 00 push 0
10003ECB 50 push eax
10003ECC 68 40400010 push 1.10004040
10003ED1 6A 07 push 7
10003ED3 FFD6 call esi
10003ED5 8B0D A4880010 mov ecx,dword ptr ds:[100088A4]
10003EDB 6A 00 push 0
10003EDD 51 push ecx
10003EDE 68 60400010 push 1.10004060
10003EE3 6A 02 push 2
10003EE5 A3 B0880010 mov dword ptr ds:[100088B0],eax
10003EEA FFD6 call esi
10003EEC 8B15 A4880010 mov edx,dword ptr ds:[100088A4]

10003EFC A3 A8880010 mov dword ptr ds:[100088A8],eax
10003F01 FFD6 call esi
安装钩子主要是为了实现全局注入的，如果发现当前进程为:"360safebox.exe"、"safeboxTray.exe"则调用：
1000114B |> \53 push ebx ; /ExitCode
1000114C |. FF15 00600010 call dword ptr ds:[<&KERNEL32.GetCurrentProcess>] ; |[GetCurrentProcess
10001152 |. 50 push eax ; |hProcess
10001153 |. FF15 4C600010 call dword ptr ds:[<&KERNEL32.TerminateProcess>] ; \TerminateProcess
如果是在explorer进程中创建两个线程，并创建事件进行通信。0006F598 0006F628 ASCII "Explorer.exe"
这种利用事件通信的方式类似于双进程保护一样，这样确保dll不太容易被删除。
下面到了重点，如果是在魔兽进程中：
0006F634 0006F63C \s2 = "wow.exe"
跟进去看，MD被vm掉了，于是乎就写api监控，结果只在里面拦截到了获取ws32里面的connect函数，其他的api没有断下。
于是乎没有下文了……
但是可以断定这是个魔兽的木马。
