蠕虫病毒

worm.win32.autorun.rzp

捕获时间

2009-12-16

危害等级



病毒症状

 该样本是使用“microsoft visual c/c ”编写的“蠕虫病毒”,由微点主动防御软件自动捕获,采用“upack”加壳方式试图躲避特征码扫描,加壳后长度为28,160字节,图标为“”, 使用“ exe”扩展名,通过网页木马、下载器下载、移动介质(如u盘)等方式进行传播。
   用户中毒后,会出现计算机及网络运行缓慢,安全软件退出等现象。

感染对象

windows 2000/windows xp/windows 2003/windows vista

传播途径

网页挂马、文件捆绑、下载器下载

防范措施

已安装使用微点主动防御软件的用户,无须任何设置,微点主动防御将自动保护您的系统免受该病毒的入侵和破坏。无论您是否已经升级到最新版本,微点主动防御都能够有效清除该病毒。如果您没有将微点主动防御软件升级到最新版,微点主动防御软件在发现该病毒后将报警提示您发现“未知木马”,请直接选择删除处理(如图1);

如果您已经将微点主动防御软件升级到最新版本,微点将报警提示您发现"worm.win32.autorun.rzp”,请直接选择删除(如图2)。

未安装微点主动防御软件的手动解决办法:

1、手动删除以下文件:

%systemdriver%\fonts\tbh.ini
%temp%\dll2.tmp
x:\ haz.pif
x:\ autorun.inf
x移动介质。

2、手动删除以下注册表键:

hkey_local_machine\software\microsoft\windows nt\currentversion\image file execution options\[安全软件]
hkey_local_machine\system\currentcontrolset\services\ haot
hkey_local_machine\system\currentcontrolset\services\aae

变量声明:

  %systemdriver%       系统所在分区,通常为“c:\”
  %systemroot%        windodws所在目录,通常为“c:\windows”
  %documents and settings%  用户文档目录,通常为“c:\documents and settings”
  %temp%           临时文件夹,通常为“c:\documents and settings\当前用户名称\local settings\temp”
  %programfiles%       系统程序默认安装目录,通常为:“c:\programfiles”

病毒分析

1、病毒运行后遍历进程查找360rp.exe和360sd.exe,如果发现就删除360rp服务,结束360rp.exe和360sd.exe进程。
2、检查"%systemroot%\system32\arp.exe"是否存在,如果不存在就退出当前进程。
3、释放并执行病毒文件"%program files%\sochst.exe。
4、退出当前进程,调用命令行自我删除。
5、在sochst.exe中,检查"%systemroot%\system32\cmd.exe"是否存在,不存在就退出进程。
6、查找病毒当前目录中是否存在autorun.inf,如果存在,就执行explorer.exe。
7、如果不存在就创建名称为"longf"的互斥量,提升自己为"sedebugprivilege"权限。
8、创建线程,枚举窗口,遍历进程,如果发现avp.exe、360sd.exe、rstray.exe、ravmond.exe等进程,就关闭这些进程创建的窗口;如果存在kswebshield.exe、kav32.exe、kpfw32.exe、vptray.exe、mctray.exer、tvscan.exe、vpc32.exe、mcshiled.exe进程,就通过释放其内存使这些进程退出;如果发现ekrn.exe,就删除ekrn服务,结束ekrn.exe和egui.exe进程;如果发现nod32krn.exe,就删除nod32krn服务,结束nod32krn.exe和nod32kui.exe进程。
9、释放并加载动态库文件"%systemdriver%\yansl.dll",并设置为系统、隐藏属性。
10、在yansl.dll中,释放驱动文件"%systemdriver%\windows\fonts\pci.sys",创建名称为"aae"的服务,恢复ssdt,遍历查找并结束
360safe.exe、360tray.exe、safeboxtray.exe、360safebox.exe、krnl360svc.exe、zhudongfangyu.exe、rstray.exe、360sd.exe、360rp.exe、kavstart.exe、kswebshield.exe、mcshield.exe等进程,删除安全软件相关文件,最后删除驱动文件。
11、创建线程,释放并加载动态库文件dll2.tmp,在dll2.tmp中,创建大量安全软件的映像劫持,查找兵刃窗口,如果找到就发送消息使其退出,连接网络,下载病毒列表,根据列表下载病毒到本地运行。
12、创建线程,遍历查找avp.exe,找到后通过卸载avp进程模块,使进程退出,停止avp相关服务。
13、删除动态库文件yansl.dll。
14、检查"%systemdriver%\system32\dllcache\linkinfo.dll"是否存在,不存在就拷贝"%systemdriver%\system32\linkinfo.dll"到此文件夹,释放驱动文件"%systemdriver%\fonts\haot.sys",创建名称为"haot"的服务,感染"%systemdriver%\system32\linkinfo.dll"。
15、遍历磁盘,在每个磁盘下创建autorun.inf和haz.pif。

病毒创建文件:

%systemdriver%\fonts\haot.sys
%systemdriver%\fonts\tbh.ini
%systemdriver%\fonts\pci.sys
%systemdriver%\yansl.dll
%temp%\dll2.tmp
x:\ haz.pif
x:\ autorun.inf
x移动介质。

病毒删除文件:

%systemdriver%\fonts\haot.sys
%systemdriver%\fonts\pci.sys
%systemdriver%\yansl.dll

病毒修改文件:

%systemdriver%\system32\linkinfo.dll
