Note: This Text file contains >>>Extremely<<< damaging
|
|
material about the American Express account making algorithm.
|
|
I do not commit credit card fraud. I just made up this scheme
|
|
because I was bored. However, I do possess some morals. I
|
|
called American Express to see if they'd have a reward for
|
|
anyone finding a loophole in there system. I was going to
|
|
tell them the loophole, get a reward and keep my mouth shut
|
|
about what I found. Well American Express didn't seem to
|
|
interested in what I discovered. In fact there "Special
|
|
Investigation Division" didn't even believe me. Now that really
|
|
burns me. In fact that got me really pissed. Since AMEX didn't
|
|
seem to interested in this information, I thought that all you
|
|
junior credit card frauders would. As for AMEX, they can kiss my
|
|
ass.
|
|
|
|
Sorry about 'Xing' out all the account numbers in this file. But
|
|
I just want to keep myself out of legal hassles.
|
|
|
|
About the System:
|
|
My system for making cards is the ONLY system that IS
|
|
100 PERCENT EFFECTIVE. Out of the 22 cards I made, all
|
|
worked. 2 cards did not pass the authorization. This was
|
|
because they were reported as lost after the date on my
|
|
cancellation bulletin. But the 2 cards would have been good
|
|
had they not have been lost.
|
|
|
|
Materials Needed:
|
|
- American Express "Cancellation Bulletin"
|
|
(You can get these from almost any store. If you're really
|
|
into carding, I suggest even attempting to BUY the book
|
|
from an employee. )
|
|
|
|
- Brain (You don't need much of one to follow my system)
|
|
|
|
About all these other card hacker programs:
|
|
|
|
In a nutshell: THEY DON'T WORK!
|
|
If you have one of these programs, throw it away. All
|
|
these programs do is spit out a randomly generated number
|
|
that doesn't mean shit.
|
|
|
|
How AMEX makes there cards:
|
|
American Express made a big fuckup in there account
|
|
algorithm. Let me demonstrate.
|
|
|
|
37XX XX XXXX 61006
|
|
37XX XX XXXX 01007
|
|
37XX XX XXXX 71007
|
|
37XX XX XXXX 81000
|
|
37XX XX XXXX 81012
|
|
|
|
Notice the last FIVE digits in the numbers. You'll
|
|
see that the second number is almost always a 1 followed by
|
|
two zeros. In other words the number 100 is almost ALWAYS in
|
|
the middle of the series of five numbers. But look at the
|
|
last number. In the middle you have a 101 and not a 100. Why
|
|
is that? Let me tell you why. It's because AMEX made a bad
|
|
mistake which I picked up on...
|
|
|
|
Card A 37XX XX XXXX 81007
|
|
^^^
|
|
Card B 37XX XX XXXX 81015
|
|
^^^
|
|
Notice these two numbers. They are almost identical
|
|
except for the last 2 digits. You see AMEX can't have two
|
|
identical card numbers can they? Of course not because then
|
|
who would they bill? What AMEX did instead was this...
|
|
|
|
37XX XX XXXX 81015
|
|
^
|
|
They changed the damn zero to a 1 and made a new check digit
|
|
for the end!! If you don't know what a check digit is. Get
|
|
Dr. Cyclops file on the "Mod 10" method of check digits. If
|
|
you can't get a hold of the file you can still make a valid
|
|
card number. Here's what you do...
|
|
|
|
Look in your cancellation book for a number similar to the
|
|
one above. Make sure that within the last 5 digits the number
|
|
101 is in the middle. Now do this....
|
|
|
|
Before - 37XX XX XXXX 81015
|
|
|
|
After - 37XX XX XXXX 81005
|
|
^
|
|
Change the 1 to a 0. Now to the number on the end add 2.
|
|
|
|
37XX XX XXXX 8100(5+2) = 37XX XX XXXX 81007
|
|
|
|
|
|
Now you have a valid card number: 37XX XX XXXX 81007
|
|
|
|
You'll notice that the card number just made matches the
|
|
Card A listed above. That is because those two cards were
|
|
cancelled together. Therefore in the cancellation bulletin
|
|
you'll want to look for a card number in the format:
|
|
|
|
XXXX XX XXXX X101X
|
|
|
|
Then you'll want to make sure that there is not an identical
|
|
card with the number:
|
|
|
|
XXXX XX XXXX X100X
|
|
|
|
Right above or below it. You see AMEX would not have made
|
|
the card number XXXX XX XXXX X101X unless there was already a
|
|
duplicate card number in existence! That alone makes my
|
|
system 100 percent effective. There is no way that the card
|
|
can't exist because it's XXXX XX XXXX X101X counterpart
|
|
WOULDN'T, COULDN'T, AND WON'T exist without a
|
|
XXXX XX XXXX X100X number being right next to it in there
|
|
account system!
|
|
|
|
Once Again:
|
|
In short do the following:
|
|
|
|
X- Number
|
|
C- Check Digit
|
|
|
|
1) Find a card number in the following format:
|
|
|
|
XXXX XX XXXX X101C
|
|
|
|
2) Change the 101 to a 100 :
|
|
|
|
XXXX XX XXXX X100C
|
|
|
|
3) Add TWO to the CHECK DIGIT IN THE CARD:
|
|
|
|
XXXX XX XXXX X100(C+2)
|
|
|
|
4) Call for authorization.
|
|
|
|
It's that easy! If you can add you can do it. Just make sure
|
|
the number 101 is in the middle of the series of 5 and you
|
|
can do this trick.
|
|
|
|
But suppose the last 5 digits in the card number are the
|
|
following:
|
|
|
|
XXXX XX XXXX 81019
|
|
|
|
If you add 2 to the check digit 9 you get 11! No problem. Just
|
|
drop the 1 in the tens place so you get this:
|
|
|
|
XXXX XX XXXX 81001
|
|
|
|
Now you have a valid number.
|
|
|
|
Remember this is 100 percent effective! No one else can say that
|
|
about there system. No one. So get a cancellation book and make
|
|
up a whole list of cards. It takes about 10 seconds to make a
|
|
card with my system so enjoy!
|
|
|
|
Final note here. Yes there are other ways to "Play the numbers"
|
|
with AMEX. So go see if you can find them like I did!
|
|
|
|
As for American Express. If there security agents are reading
|
|
this, let me offer a cheap solution...
|
|
|
|
1) GET RID OF THOSE USELESS CANCELLATION BULLETINS!!
|
|
No one fucking uses them! (Except people like me!)
|
|
|
|
2) REQUIRE that a valid expiration date be given with each
|
|
authorization. That way you can keep your damn bulletins.
|
|
You see my system just makes the account number. I can't make
|
|
the expiration date!
|
|
|
|
3) When someone calls one of your operators for a validation be
|
|
sure that your operators handle the situation like this ...
|
|
|
|
Operator - "Account number please"
|
|
|
|
Frauder - "37XX XX XXXX XXXXX"
|
|
|
|
Operator - "Expiration Date"
|
|
|
|
Frauder - "Ahhh... 10/90"
|
|
|
|
Operator - "I'm sorry that account is invalid"
|
|
|
|
NOTICE that the operator did not say that the DATE was invalid.
|
|
NOR did s/he say that the CARD NUMBER was invalid. S/he should
|
|
not make a distinction to the person trying to get authorization.
|
|
That way you always keep the frauder guessing...
|
|
|
|
Frauder "Gee I wonder whether the expiration date is bad. Or is
|
|
it the account number? Or is it both?"
|
|
|
|
You see that is a great and cheap defense. Too bad AMEX is too
|
|
damn ignorant to see it.
