Phreak codes are fast running out, and people are getting caught. Its time to pioneer a brand new industry. 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…


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.

If you have something you can add to this file then please tell me…
