关于GenPack:Backdoor.Generic木马的分析报告
Finn
一、病毒标签：
病毒名称： GenPack:Backdoor.Generic
病毒类型： 后门类
文件 MD5：326bf248d364ed48d742856109cbf97a
公开范围： 完全公开
危害等级： 4
文件长度： 1,403,638 字节
感染系统： windows 98以上版本
加壳类型： 未知壳
二、病毒描述：
病毒运行后，复制自身到系统目录下，衍生病毒文件。创建注册表方式达到随机启动的目的。进程进行键盘记录，主动访问网络连接病毒服务端，连接成功后中毒电脑会受到远程控制。
三、行为分析：
1、 病毒运行后，复制自身到系统目录下，衍生病毒文件，并删除自身。病毒运行后其副本系统目录下为隐藏属性，且病毒及副本的图标显示为文件夹，来欺骗中毒用户点击:
2、 感染U盘上的文件，修改原文件夹为隐藏，并创建相同名字的exe文件，欺骗用户点击。
C:\WINDOWS\system32\B80A3E\127A0E.EXE
C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\E_N4
（%USERPROFILE%\Local Settings\Temp）
[.ShellClassInfo]
LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21787
病毒在temp目录下释放八个文件(后经分析，发现为dll文件)：
2、修改注册表，以更改Internet的默认设置：
KEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
HKCU\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers\C:\WINDOWS\system32\B80A3E\127A0E.EXE
在可执行文件的属性对话框、兼容性标签页里勾选“以管理员身份启动该程序”复选框。这等效于在HKCU \Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers注册表分支下添加键值，也相当于修改C:\Windows \AppPatch下的sysmain.sdb兼容性数据库。
windows映像劫持技术（IFEO）
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\127A0E.EXE
Date & Time: 2009-11-23 11:24:49
Event Class: File System
Operation: WriteFile
Result: SUCCESS
Path: C:\Documents and Settings\Administrator\「开始」菜单\程序\启动\127A0E.lnk
TID: 1504
Duration: 0.0000449
Offset: 0
Length: 677
[.ShellClassInfo]
InfoTip=@Shell32.dll,-12690
IconFile=%SystemRoot%\system32\SHELL32.dll
IconIndex=-238
LocalizedResourceName=@shell32.dll,-28996
3、进程进行键盘记录，访问网络,等待病毒服务端连接，连接成功后中毒电脑会受到远程控制。
127A0E.EXE:2232 TCP 20090818-0938:3036 mailitciberia.com:http CLOSE_WAIT
电信在他的DNS里搞了鬼，所有不能用的域名统统转到60.191.124.236，也就是在IE里面输入一些不能解析的域名时，也会转到那里去，几时经常看到的114页面，还有难看的

（除cnvpe.fne，其他七个dll全部加载。。）
注释：
%Windir% WINDODWS所在目录
%DriveLetter% 逻辑驱动器根目录
%ProgramFiles% 系统程序默认安装目录
%HomeDrive% 当前启动系统所在分区
%Documents and Settings% 当前用户文档根目录
%Temp% 当前用户TEMP缓存变量；路径为：
%Documents and Settings%\当前用户\Local Settings\Temp
%System32% 是一个可变路径；
病毒通过查询操作系统来决定当前System32文件夹的位置；
Windows2000/NT中默认的安装路径是 C:\Winnt\System32；
Windows95/98/Me中默认的安装路径是 C:\Windows\System；
WindowsXP中默认的安装路径是 C:\Windows\System32。

四、清除方案：
按照行为分析手工清除对应文件，恢复相关系统设置。
(1) 使用windows任务管理器或者IceSword结束127A0E.EXE进程
(2) 删除病毒文件
%WINDIR%\Winmgnts.exe
%WINDIR%\Winmgnts.DLL
%WINDIR%\WinmgntsKey.DLL
%WINDIR%\Winmgnts_Hook.DLL
