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25,532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);

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%\dll1.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\ xtpin
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.检查"%systemroot%\system32\taskmgr.exe"是否存在,不存在就退出进程。
2.设置自己为系统、隐藏属性,查找当前目录中是否存在autorun.inf,如果存在,就执行explorer.exe。
3.如果不存在就创建名称为"yming"的互斥量,提升自己为"sedebugprivilege"权限。
4.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。
5.释放并以pktv为参数加载动态库文件"%systemdriver%\zjl.dll",并设置动态库文件为系统、隐藏属性。
6.在zjl.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
7.360safe.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。
8.创建线程,释放并加载动态库文件dll1.tmp,在dll1.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。
9.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。
10.删除动态库文件zjl.dll。
11.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\xtpin.sys",创建名称为"xtpin"的服务,感染"%systemdriver%\system32\linkinfo.dll"。
12.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\xtpin.sys
%systemdriver%\fonts\tbh.ini
%systemdriver%\fonts\pci.sys
%systemdriver%\zjl.dll
%temp%\dll1.tmp
x:\ haz.pif
x:\ autorun.inf
x移动介质。
病毒删除文件:
%systemdriver%\fonts\xtpin.sys
%systemdriver%\fonts\pci.sys
%systemdriver%\zjl.dll
病毒修改文件:
%systemdriver%\system32\linkinfo.dll
