1.生成文件
c:\ProgramFiles\meex.exe
c:\ProgramFiles\CommonFile\System\.exe
c:\ProgramFiles\CommonFiles\MicrosoftShared\.exe
2.修改注册表,添加启动项,以达到随机启动的目的
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
Default="C:\ProgramFiles\CommonFiles\System\.exe"
3.删除注册表安全模式的有关信息,当开机时不能启动安全模式
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\{4D36E967-E325-11CE-BFC1-08002BE10318}
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal\{4D36E967-E325-11CE-BFC1-08002BE10318}
Defualt="DiskDrive"
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\{4D36E967-E325-11CE-BFC1-08002BE10318}
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot\Network\{4D36E967-E325-11CE-BFC1-08002BE10318}
Defualt="DiskDrive"
4.改变注册表值使隐藏文件不可见,达到病毒体隐藏目的
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL
CheckedValue=dword:00000000
5.禁用此计算机上的帮助与支持中心服务:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\helpsvc
Start=dword:00000004
6.禁用网络地址转换、寻址、名称解析、和入侵保护服务:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess
Start=dword:00000004
7.禁用监视系统安全设置和配置服务:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wscsvc
Start=dword:00000004
8.禁用下载和安装Windows更新服务:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\wuauserv
Start=dword:00000004
9.映像劫持
通过在HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\ImageFileExecutionOptions下添加注册表项来进行文件映像劫持,可阻止大量安全软件及系统治理软件运行,并执行病毒体。
