So far I think this file is original,
so I am writing it.

Most, if not all people have calling
cards from AT&T. They can be used from
any phone to dial long distance and
charge it to your AT&T bill. The
objective, to use someone elses card to
get free long distance service. These
codes are not traced, and they are only
FOUR digits! The nice part is you can
hack the code for anyone you like and
attack a specific person, not a random
name like when hacking MCI. Take your
worst enemy, when you know his phone
number, its the end...

Format:
a. Dial 0.
b. Dial phone number with area code.
c. Wait for tone.
d. Dial billing number with or without
area code.

If your code is correct, the fone
will ring. If it is not correct a
recording will say "Please dial your
card number again, the card number you
have dialed is invalid". You can try
another four digits but after that it
will tell you to call AT&T if it is
still invalid.

This is more of a pain to hack
because there are a thousand possible
codes for each phone number. Just
make a short basic program to do the
job of dialing all the codes. its
best to do a random scan instead of
sequential in my opinion.
