进入sub_40123E后，首先创建了一个互斥Srv3231415，失败的话此程序就退出了；
然后又去查询注册表HKLM\Software\Microsoft\Windows\CurrenteVersion\srv32下
"D"的值，如果srv32存在D的键值不为0则调用sub_4030EB，代码如下：

在sub_4030EB里打开了socket，并创建了两个线程（动作越来越明显了 ^…^）。
由于我第一次执行没有此键值所以跳转了，我们就先看跳转的情况吧：

现在还不知道这些数据做什么用的，先继续往下看...

CODE:004012A8 call sub_4019A5 ; 打开已存在的文件srv32res，并得到其大小

CODE:004012C1 jb short loc_4012C8 ; 如果文件sccss小于8个字节则跳转
这里调用sub_4019A5来判断Windows目录下文件Srv32Res和sccss的大小，第一次执行到这里没有这两个
文件，所以跳转了。
CODE:004012C3 loc_4012C3:
CODE:004012C3 call sub_40148D
CODE:004012C8
CODE:004012C8 loc_4012C8:

CODE:004012DE call WaitForSingleObject
CODE:004012E3 jmp short loc_4012C8
这一段代码会不断执行 sub_401575,sub_40148D直到sub_401575的返回值（eax）不等于0；
看了这两个函数应该事关键了，我们先看看函数sub_401575:
CODE:00401575 sub_401575 proc near
CODE:00401575 var_4 = dword ptr -4
CODE:00401575 enter 4, 0
CODE:00401579 push esi

CODE:00401581 push offset dword_406587
CODE:00401586 call sub_4014CA ; 读文件Srv32tsk的内容,存放到[406587]
CODE:0040158B cmp eax, 0FFFFFFFFh

CODE:00401590 mov esi, eax

CODE:004015A2 push esi ; hObject
CODE:004015A3 call CloseHandle
CODE:004015A8 jmp short loc_4015E1
跟进sub_4014CA看看它读文件的操作
CODE:004014CA sub_4014CA proc near
CODE:004014CA NumberOfBytesRead= dword ptr -8
CODE:004014CA lpBuffer = dword ptr 8

CODE:004014DD push offset aSrv32tsk ; lpFileName = "Srv32tsk"
CODE:004014E2 call CreateFileA
CODE:004014E7 cmp eax, 0FFFFFFFFh
CODE:004014EA jz short locret_40152D ; 打开文件失败则退出
打开Windows目录下的文件srv32tsk，到CreateFileA会失败，我们可以先建一个文件
srv32tsk，然后看它对文件做了些什么操作

文件srv32tsk打开失败的话直接退出，如果读文件成功，比较从文件开始读的第4个DWORD
值是否为0，不等于0关闭文件退出此函数，等于0的话比较第2个DWORD值是否为0，如果第
2个DWORD值不为0的话调用sub_40171C，然后又调用sub_401531写文件srv32tsk。
文件srv32tsk的头部的结构大概是这样的
struct tagSRV32TSK_HEAD
{
DWORD dword_406587;
DWORD dword_40658B;
DWORD dword_40658F;
DWORD dword_406593;
DWORD dword_406597;
DWORD dword_40659B;
BYTE[8] unk_40659F;
DWORD dword_4065A7;
};
这一段代码里调用了一个函数sub_40171C:
CODE:0040171C sub_40171C proc near
CODE:0040171C mov eax, ds:dword_40658F ; 从文件srv32tsk开始的第3个DWORD值
CODE:00401721 rcl eax, 0Dh
CODE:00401724 rcl edx, 1
CODE:00401726 rcl eax, 1
CODE:00401728 rcl edx, 1
CODE:0040172A rcl eax, 1
CODE:0040172C rcl edx, 1
CODE:0040172E rcl eax, 1
CODE:00401730 rcl edx, 1
CODE:00401732 rcl eax, 1
CODE:00401734 rcl edx, 4
CODE:00401737 rcl eax, 1
CODE:00401739 rcl edx, 1
CODE:0040173B rcl eax, 1
CODE:0040173D rcl edx, 3
CODE:00401740 rcl eax, 1
CODE:00401742 rcl edx, 1
CODE:00401744 rcl eax, 1
CODE:00401746 rcl edx, 1
CODE:00401748 rcl eax, 1
CODE:0040174A rcl edx, 2
CODE:0040174D rcl eax, 1
CODE:0040174F rcl edx, 1
CODE:00401751 rcl eax, 1
CODE:00401753 rcl edx, 1
CODE:00401755 rcl eax, 1
CODE:00401757 rcl edx, 1
CODE:00401759 rcl eax, 1
CODE:0040175B rcl edx, 1
CODE:0040175D rcl eax, 1
CODE:0040175F rcl edx, 1
CODE:00401761 rcl eax, 1
CODE:00401763 rcl edx, 1
CODE:00401765 rcl eax, 1
CODE:00401767 rcl edx, 2
CODE:0040176A rcl eax, 1
CODE:0040176C rcl edx, 1
CODE:0040176E rcl eax, 1
CODE:00401770 rcl edx, 1
CODE:00401772 rcl eax, 1
CODE:00401774 rcl edx, 6
CODE:00401777 and edx, 0F8CEFEE0h
CODE:0040177D bswap edx
CODE:0040177F mov ds:dword_406597, edx ; 文件srv32tsk的第5个DW值
CODE:00401785 xor edx, edx
CODE:00401787 mov ds:dword_40659B, edx ; 文件srv32tsk的第6个DW值
CODE:0040178D retn
CODE:0040178D sub_40171C endp
对文件srv32tsk操作完后返回到sub_40123E
CODE:004012CD test eax, eax ; 如果打开文件srv32tsk出错,eax == 0
CODE:004012CF jnz short loc_4012E5
CODE:004012D1 call sub_40148D
CODE:004012D6 push 0FFFFFFFFh ; dwMilliseconds = INFINITE
CODE:004012D8 push ds:hHandle ; hHandle
CODE:004012DE call WaitForSingleObject
CODE:004012E3 jmp short loc_4012C8
现在还有一个会频繁执行的函数sub_40148D
CODE:0040148D sub_40148D proc near
CODE:0040148D cmp ds:ThreadId, 0
CODE:00401494
CODE:00401494 loc_401494:
CODE:00401494 jnz short locret_4014C9
CODE:00401496 cmp ds:hHandle, 0FFFFFFFFh
CODE:0040149D jz short loc_4014AA
CODE:0040149F push ds:hHandle ; hObject
CODE:004014A5 call CloseHandle
CODE:004014AA
CODE:004014AA loc_4014AA:
CODE:004014AA push offset ThreadId ; lpThreadId
CODE:004014AF push 0 ; dwCreationFlags
CODE:004014B1 push 0 ; lpParameter
CODE:004014B3 push 401DB0h ; lpStartAddress
CODE:004014B8 push 2000h ; dwStackSize
CODE:004014BD push 0 ; lpThreadAttributes
CODE:004014BF call CreateThread
CODE:004014C4 mov ds:hHandle, eax
CODE:004014C9
CODE:004014C9 locret_4014C9:
CODE:004014C9 retn
CODE:004014C9 sub_40148D endp
创建了一个线程（^_^，到这里才刚刚开始噢！），肯定不会干什么好事，下次
我们再详细分析这个线程。
到这里有个2问题：
1. 由函数sub_4033E7算出的内存数据做何用？
2. 文件srv32Res,sccss何srv32tsk做何用？
