行为分析
1、释放以下文件并设置为隐藏和系统属性。
%WINDIR%\system32\bryato.dll
%WINDIR%\system32\bryato.exe
%WINDIR%\system32\severe.exe
%WINDIR%\system32\drivers\conime.exe
%WINDIR%\system32\drivers\fubcwj.exe
2、在每个分区的根目录下生成文件：Autorun.inf 和病毒复制体：OSO.exe ，并修改相关注册表项以使用户双击打开该分区时运行病毒体：
修改的注册表项：HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoDriveTypeAutoRun 0xB5
Autorun.inf内容如下：
[AutoRun]
open=OSO.exe
shellexecute=OSO.exe
shell\Auto\command=OSO.exe
3、添加或修改注册表项以隐藏病毒文件：
HKLM\software\microsoft\windows\currentversion\explorer\advanced\folder\hidden\showall\CheckedValue "0"
4、添加以下注册表项以达到自启动的目的。
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\fubcwj "%WINDIR%\System32\bryato.exe" 
HKLM\Software\Microsoft\Windows\CurrentVersion\Run\bryato "%WINDIR%\System32\severe.exe"
5、修改以下注册表项以达到随Explorer进程启动的目的：
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell "Explorer.exe %WINDIR%\System32\drivers\conime.exe"
