This program was designed on work done by Dr. Cyclops and The Alias.
|
|
An IBM version of this program has already been released.
|
|
|
|
CC Maker will generate randomized card numbers for your use. For
|
|
details on how it works, read the second segment of this file which is the
|
|
text file itself around which I based the program.
|
|
|
|
The program and how to use it are pretty evident, whenever you want it
|
|
to stop generating card numbers, press space bar. There is no expiration
|
|
date, but you need not worry. Just make up any reasonable date, it really doesn
|
|
't matter, just make sure you don't give whoever an expired date.
|
|
|
|
|
|
MAKING YOUR OWN CARD TYPE
|
|
|
|
There are two things this option may be used for. The first is to
|
|
check if a credit card number is real, let's say you saw one posted and want
|
|
to test to see if it isn't just something someone made up. Type in all the
|
|
digits EXACTLY EXCEPT FOR THE LAST DIGIT. Now instead of typing in the last
|
|
digit type an X, then hit RETURN to proceed. The program will clear the
|
|
screen and present you with the valid checksumed number. Look at the last
|
|
digit on the number on the screen, and the last digit that you didn't type in.
|
|
If they are the same, the card number is probably real. If not. The card
|
|
isn't.
|
|
|
|
The second thing this option may be used for is for generating card
|
|
numbers for other credit cards than the ones shown. You have the options:
|
|
|
|
X
|
|
0-9
|
|
spacebar
|
|
|
|
Yyou enter the format in, placing X where there is a random digit and 0-9
|
|
where there is a non-changing digit. You may use 'spacebar' to help
|
|
seperate the columns, but it has no effect on the program.
|
|
|
|
Example:
|
|
|
|
3XXX XXXX XXXX XXXX
|
|
|
|
The card number always starts with a 3, then is followed by 15 random
|
|
digits. The spaces are just in there to make the number easier to read.

Last Update : June 19 - 1989
|
|
|
|
The information presented in this article is NOT intended to be used for
|
|
illegal purposes - I don't know anything legal it can be used for - but I'm
|
|
not responsible for whatever uses you may have for it.
|
|
|
|
** NOTE **
|
|
|
|
The original article was written by the Line Breaker (P.P.O.A.). However, I,
|
|
Dr. Cyclops, of the infamous Supreme Beings Corporation of America,
|
|
headquarters Detroit Lakes, MN, with branch offices in three other states and
|
|
several countries in Europe, have discovered some loopholes in his article.
|
|
Missing or puzzling information has been filled in where needed. Another note-
|
|
There is also a program to go along with this file - should be done within a
|
|
week of the last update of this article.
|
|
|
|
Sophisticated computer programs have been developed to analyze past
|
|
experiences, to score applications and to recommend future changes in an
|
|
attempt to reduce the loss from uncollectible accounts. It would be very
|
|
difficult to process a large number of credit card applications today without
|
|
such a technique.
|
|
|
|
In developing the unique account number to be assigned to a successful
|
|
applicant, the use of a check digit is usually employed. The computer creates
|
|
the check digit by using the first N - 1 digits of the account number as input
|
|
to a check digit generation routine. The resulting calculations produce a
|
|
single, unique digit, which becomes the last digit of the account number.
|
|
|
|
Since this isn't really helping much - let's just dig in with a good example
|
|
of a store common to pretty much everybody - Daytons!!! The format of a Daytons
|
|
card is as follows (I don't have one handy but all you really need for scamming
|
|
is a number).
|
|
|
|
DAYTONS
|
|
XXX XXX XXXC
|
|
|
|
The credit card displayed uses a 9 digit account number, with the first eight
|
|
digits (XXX XXX XXX) being the actual account number in blocks of threes, and
|
|
the ninth digit (C) being the check digit. The use of a check digit helps
|
|
reduce errors in the transcription of account numbers.
|
|
|
|
When an item is purchased and the value of the item is high enough to warrant
|
|
a card validity check - the number is first checked through the little black
|
|
and white newsprint book (found on top of most store cash registers) to see if
|
|
it's stolen or not then (usually) it is phoned in to one of many various
|
|
credit card verification services. The verification service re-checks to make
|
|
sure the card isn't stolen or reported lost - then it checks the number to see
|
|
if the card is valid (the check number that you will soon learn how to generate
|
|
on your own), then checks to see if the appropriate funds are available. From
|
|
there the person whom you talk to (could be a machine - some are for speed)
|
|
will tell the merchant whether to accept the card or not - and if not - what
|
|
steps he/she should do next.
|
|
|
|
On with our little scheme...
|
|
|
|
Since you'll probably want to do a little practice first before doing actual
|
|
scamming - let's start using a made up number, let's just use the card number
|
|
123 456 78 - since we don't yet have a check digit - let's just generate one.
|
|
See example below next paragraph.
|
|
|
|
To generate a check digit using the 'Mod 10' technique, work from right to
|
|
left. First, multiply the digits in the odd positions (8,6,4,2) by 2. If an
|
|
individual result from any multiplication is greater than or equal to 10 (e.g.
|
|
2 x 8 = 16) - add 1 to the units position (6 + 1 = 7) and discard the digit in
|
|
the 10's position. Or in other terms - just subtract 9 from the value. Sum
|
|
these results (4 + 8 + 3 + 7 = 22) along with the even positioned account
|
|
digits (22 + 1 + 3 + 5 + 7 = 38). The check digit for this account number is
|
|
the digit that must be added to the ones place to make the total value (38)
|
|
evenly divisible by 10 (2 in our example : 38 + 2 = 40). That's all there is
|
|
to it!!! ALWAYS remember that when generating a check digit - to start from the
|
|
right - so the rightmost account digit is position 1. Also - I would NOT
|
|
recommend using this number - it looks just a bit obvious.
|
|
|
|
Example of Daytons check digit generation...
|
|
|
|
/ ---------------------------------------------------\
|
|
| position : 8 7 6 5 4 3 2 1 |
|
|
| |
|
|
| # x 2 = : 4 8 12 16 |
|
|
| adj val : 4 + 8 + 3 + 7 = 22 |
|
|
| / \ / \ / \ / \ |
|
|
| | | | | |
|
|
| acct # : 1 2 3 4 5 6 7 8 ? |
|
|
| | | | | |
|
|
| \ / \ / \ / \ / |
|
|
| # x 1 = : 1 + 3 + 5 + 7 = 16 |
|
|
| |
|
|
| Add the summed values : 22 + 16 = 38 |
|
|
| Now adjust to make it divisible by 10 : |
|
|
| 40 - 38 = 2 |
|
|
| So 2 is the check digit - Now your valid Daytons |
|
|
| card number is : 123 456 782 |
|
|
\----------------------------------------------------/
|
|
|
|
Here is a list of the values that should be obtained for each number that
|
|
occurs.
|
|
|
|
-------------------------------------------------------------------------------
|
|
Number Position Value Number Position Value
|
|
------ -------- ----- ------ -------- -----
|
|
1 Even 01 1 ODD 02
|
|
2 " 02 2 " 04
|
|
3 " 03 3 " 06
|
|
4 " 04 4 " 08
|
|
5 " 05 5 " 01
|
|
6 " 06 6 " 03
|
|
7 " 07 7 " 05
|
|
8 " 08 8 " 07
|
|
9 " 09 9 " 09
|
|
0 " 00 0 " 00
|
|
------------------------------------------------------------------------------
|
|
|
|
(Note that in the above example, that is the correct way of doing it, (i.e. if
|
|
you happen to be using a Daytons credit card format). If you happen to have
|
|
a different type of card - use the same method - and still work from right to
|
|
left.
|
|
|
|
I have also discovered some more information on the subject. In the original
|
|
article, the VISA was listed as having the same format as MasterCard, I found
|
|
it to be different. Here are also a couple of different types of cards with
|
|
their formats. ALL use this check number verification system. If you happen
|
|
to find a different type of card, try this method, if it works for your card,
|
|
it should work on others.
|
|
|
|
In ALL of the following card format examples - X stands for digit and C stands
|
|
for the check digit. On some cards - some digits MUST contain certain values -
|
|
if they don't your chances of getting busted skyrocket. On those cards - the
|
|
digit will be shown in the correct position.

I don't remember the number format, but a good place to POSSIBLY scam stuff
|
|
from is Nieman Marcus. A very exclusive overpriced yuppie shopping store. I
|
|
don't know how they do their mail order business - but I suspect they do check
|
|
their credit card orders well.

Since many businesses don't want their customers being ripped off by those
|
|
who might use this information to illegal ends - several companies have made
|
|
available places you can call by fone to check if a card has been stolen and
|
|
if it has sufficient funds to cover the purchase. To this section The Alias
|
|
gets most of the credit since he did most of the work here.

When using a verification number, you also need a merchant number to tell the
|
|
verification place how much business their client is getting. At the place
|
|
where I worked - and I suspect most other places - the merchant number is 10
|
|
digits long. Verification numbers are only used by places to check if a card
|
|
number is valid (what you hopefully did correctly using the above process).\
|
|
Verification numbers do NOT have to be used in all instances - the minimum
|
|
amount for a verification number to be used is $50 or Visa and $75 for
|
|
American Express. I don't know what the amounts are for Discover (or the
|
|
Discover Card format - Somebody help me out) though.

*************************************
|
|
* USING SELF GENERATED CARD NUMBERS *
|
|
*************************************
|
|
|
|
If you get a credit card number from a BBS to charge calls to or other - use
|
|
the above process to check if it's okay. Better yet - if you by some chance
|
|
find/borrow/steal or in any way get a Real credit card - use it as quickly
|
|
as possible as it will most likely soon be reported stolen. Always check
|
|
to see if a card is valid or stolen BEFORE using it. Either use the above
|
|
verification numbers - or steal one of those black and white newsprint books
|
|
found on all cash registers (they won't miss 'em - they get two new updates
|
|
a month).
|
|
|
|
The only SURE use of self generated card numbers, if you're perverted, is for
|
|
phone sex places. Simply create a number using the above technique (almost
|
|
all take Visa), then call up the place (use a 1 - 800 number or they'll need
|
|
your fone # to call you back then you're toast) and tell them you want however
|
|
long you want to have fone sex (half hour or whatever). Give them the card
|
|
type, the card number, and the expiration date (make one up - they never have
|
|
a record of it at the verification place - they just want to make sure the
|
|
card is still good). Now wait a few moments while they check it out. If
|
|
no problems - enjoy your new fone friend. Have fun - but not around me!!!
