While this has nothing specifically to do with Backtrack.
As predicted by you the simple answer is "no" however I will try to sum up a few points and justify the answer.
In the post you mention you are a "newbie" this is not a bad thing after all everyone has to start as a newbie, however, these things can cause a lot of damages in real world and can cost companies a lot of money. I suggest you leave this idea alone until you get more experience and a security related job, doing this without legal authority of course is not supported on this forum.
If you really wish to stop building your penlab and make the vulnerability obvious there are a lot of Vulnerable Machines which you can download either as an ISO or VM and use them in your lab to learn, same thing goes for different websites with challenges. Another alternative with for this is simply find someone you know who's interested in security also and ask him to setup your penlab with different ideas.
As mentioned above real life attacks are to be made by professional pentesters who have legal authorisation to do it. There are many reasons for this and I suggest you follow the advice
