Posted on September 22, 2012 by gatomalo
gAtO wAs– surfing around and found this information targeted at future cyber gAtIcOs- These are the basic tricks that the bad guy’s are using to game the system. and they share this basic information to help other stupid wanna-bee bad guys. TRUST but VERIFY – be a critical reader and remember that this comes from bad guy’s always trying to trick you. I checked out most of the LINKS and deleted any ones I though may be bad. Some of this is a bullshit, some stupid and some is real from what I can tell – enjoy–gATO oUt

for educational PURPOSES ONLY. – how the Cyber Criminals are using the system for cyber–money laundering.

Cracking The Credit Card Code


Credit Cards 2 BTC-Bitcoin – BTC-Bitcoin 2 Credit Cards

Wasn’t quite sure where to put this, but I decided I’d share some information on the actual code of a credit card.

In reading this you will be able to interpret credit card codes efficiently and actually be able to learn about the card itself. This is all simply by knowing the 16 digits on the front of a card.

The first digit of a card is called the Major Industry Identifier (MII). It designates the category of the entity which issued to card. This is useful in finding what exactly the card is for.

1 and 2 are Airlines,

3 is Travel and Entertainment

4 and 5 are Banking and Financial

6 is Merchandizing and Banking

7 is Petroleum

8 is Telecommunications

9 is a National assignment

The first 6 digits are the Issuer Identification Number (IIN). It will identify the institution that issued the card.

Visa: 4xxxxx

Mastercard: 51xxxx – 55xxxx

Discover: 6011xx, 644xxx, 65xxxx

Amex: 34xxxx, 37xxxx

Cards can be looked up by their IIN. A card that starts with 376211 is a Singapore Airlines Krisflyer American Express Gold Card. 529962 designates a pre-paid Much-Music MasterCard.
The 7th and following digits, excluding the final digit, are the person’s account number. This leaves a trillion possible combinations.

The final digit is the check digit or checksum. It is used to validate the credit card number using the Luhn algorithm

How to use this information to validate a credit card with your brain:

Take the below number (or any credit card number)

4417 1234 5678 9113

Now, double every other digit from the right

(4×2, 1×2, 1×2, 3×2, 5×2, 7×2, 9×2, 1×2)

Add these new digits to the undoubled ones (4, 7, 2, 4, 6, 8, 1, 3)

All double digit numbers are added as a sum of their digits, so 14 becomes 1+4.

8+4+2+7+2+2+6+4+1+0+6+1+4+8+1+8+1+2+3 = 70

If the final sum is divisible by 10, then the credit card number is valid.

If it’s not divisible by 10, the number is invalid or fake.

In this case, 70 is divisible by 10, so the credit card number is indeed valid. This works with every credit card and opens many ideas to the mind.

Credit Cards to BTC-Bitcoin

These are methods that have been discussed on HackBB for cashing CCs into bitcoins. Before I continue let me get this out of the way. No you can not cash your CVV directly into bitcoins. Exchangers know the risk involved in accepting reversible credit for non-reversible currency, and the few that have ever accepted direct CC payments were scammed out of business. There are ways around this issue..

CC -> SLL -> BTC

Editors Note:

VirWox wised up to this method and started forcing users to validate their SL avatars..

Thought I’d tidy this up a bit with a noob-friendly tutorial on how to buy bitcoins with a CVV through VirWox.

What you will need.

Valid CVV (any country will do)
Clean Socks5 proxy as close as possible to cardholder’s address
Good DNS setup
Ok lets get started.

You’ll need an email account. Go create a new one at yahoo/gmail/whatever…..doesn’t matter which (i wouldn’t use tormail for this……too much of a flag).

Go to https://www.virwox.com/, and create a new account
