行為分析
:
1、病毒運行後釋放病毒檔案:
%WINDIR%\exert.exe
%WINDIR%\io.sys.bak
%WINDIR%\lsass.exe
%Program Files%\Common Files\intexplore
其中除%WINDIR%\io.sys.bak外均為病毒自身。
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.exe
新建鍵值: 字串: "默認"="WindowFiles"
原鍵值: 字串: "默認"="exefile"
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Applications \iexplore.exe\shell\open\
原鍵值: 字串: "默認"=""C:\Program Files\Internet Explorer\iexplore.exe" -nohome"
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\opennew\command
新建鍵值: 字串: "默認"=""C:\Program Files\common~1\INTEXPLORE.pif" %1"

HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet
新建鍵值: 字串: "默認"="INTEXPLORE.pif"
原鍵值: 字串: "默認"="IEXPLORE.EXE"
3、新建註冊表,添加啟動項,以達到隨機啟動的目的:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
\CurrentVersion\Run\
鍵值: 字串: "ToP "="C:\WINDOWS\LSASS.exe"
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main
鍵值: 字串: "Check_Associations "="No"
HKEY_CURRENT_USER\Software\Microsoft\Windows
\ShellNoRoam\MUICache\
鍵值: 字串: "C:\Program Files\common~1\INTEXPLORE.pif
"="INTEXPLORE"
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WindowFiles\
鍵值: 字串: "默認"="%1"
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WindowFiles
\DefaultIcon
鍵值: 字串: "默認"="%1"
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WindowFiles\Shell\
鍵值: 字串: "默認"="C:\WINDOWS\EXERT.exe "%1" %*"
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WindowFiles
\Shell\Open\
鍵值: 字串: "默認"="C:\WINDOWS\EXERT.exe "%1" %*"
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WindowFiles\Shell
\Open\Command
鍵值: 字串: "默認"="C:\WINDOWS\EXERT.exe "%1" %*"
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\WindowFiles\Shell
\Open\Command
鍵值: 字串: "默認"="C:\WINDOWS\EXERT.exe "%1" %*"
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet
\ INTEXPLORE.pif
鍵值: 字串: "默認"="INTEXPLORE"
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet
\INTEXPLORE.pif\LocalizedString
鍵值: 字串: "默認"="INTEXPLORE"
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet
\INTEXPLORE.pif\shell\
鍵值: 字串: "默認"=""C:\Program Files\common~1\INTEXPLORE.pif""
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet
\INTEXPLORE.pif\shell\open\
鍵值: 字串: "默認"=""C:\Program Files\common~1\INTEXPLORE.pif""
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet
\INTEXPLORE.pif\shell\open\command\
鍵值: 字串: "默認"=""C:\Program Files\common~1\INTEXPLORE.pif""
HKEY_LOCAL_MACHINE\SOFTWARE\Clients\StartMenuInternet
\INTEXPLORE.pif\shell\open\command
鍵值: 字串: "默認"=""C:\Program Files\common~1\INTEXPLORE.pif""
註:% System%是一個可變路徑。病毒通過查詢作業系統來決定當前System資料夾的位置。Windows2000/NT中默認的安裝路徑是C:\Winnt\System32,windows95/98/me中默認的安裝路徑是C:\Windows\System,windowsXP中默認的安裝路徑是C:\Windows\System32。
