If you want to get back at your friend then this section is right for you. These steps, when done right, can give you access to VERY valuable information.
The basic jyst:
What we are basically trying to do here is to fool the person's ISP (that you want to screw with) into giving you informaton such as passwords. Most ISPs offer web space and maybe an additional mailbox. So you can see how much fun this could get. But most of this is done by phone, so if you are a shy chicken and are afraid of talking to people on the phone then just stop reading this now.
PreHack:
First you need to get some information about the person you dislike, Such as e-mail address (sometimes you don't even need that) and his mother's maiden name (don't worry – that's not too hard to get). You also need the number to call for that ISP, and you can usually get that off his website.
What to do:
1) Getting e-mail - Simple, all you have to do is ask them to send you something. Or if they don't trust you, refer to the chapter "HTML and JAVA Hacking" to find out how to secretly get their addy.
2) Getting Mother's Maiden Name - This might be a little more difficult to get. But you would be suprised as to what people would tell you. What I did was I started a conversation about people's backgrounds and I told my victim that I would find his anscestors for him on the internet if he would give me his mother's maiden name. It works – trust me.
3) Now call up his ISP and speak to customer service. Tell them the person's necessary info. The conversation should go something like this:
ISP: Hello, user ID or e-mail please.
You: (Whatever their e-mail is)
ISP: OK, what's your mothe'rs maiden name?
You: (Whatever their mother's maiden name is)
ISP: OK, what seems to be the problem?
You: I forgot my password for my mail box!
ISP: Oh, ok. Hold on... It's "jhsuhiz" (or whatever).
You: All right, thanks. Oh, and I would like to make
another mailbox.
ISP: Ok. What would you like your new mailbox name to
be?
You: (Whatever you wish)
ISP: And would you like to keep the same password or
change it?
You: Change it please to "kanmdet" (or whatever).
ISP: Ok, this will take about 12 to 24 hours to
activate.
You: Thanks.
Now you can use someone else's e-mail for whatever purpose you would like! And it would be hard to trace it back to you, it would usually be traced to the person who you are screwing.
Warning! It is always a good idea to not call the ISP from you home. They will trace it back to you.
