ZenCart MaxMind minFraud (e-Commerce Fraud Detection)

MaxMind Credit Card Fraud Detection v1.4 for ZenCart

Overview
1. This has been tested on ZenCart 1.3.9h, your mileage on earlier versions may vary.
2. This addon will allow the store owner to query the MaxMind server to identify and place a risk score on transactions.
3. You MUST have an account with MaxMind to use this addon! You may get a test license with 1000 queries at:
http://www.maxmind.com/app/ccv2r_signup

4. From MaxMind website:
Fraudster techniques becoming more advanced
Techniques used in online card-not-present fraud are becoming more and more sophisticated. Traditional fraud screening tools can only determine if a credit card is legitimate or if the user-entered account information matches those on record. Today, fraudsters can obtain personal credit card information, pose as the legitimate card holder, and bypass standard fraud checks.

Looking at fraud from a different angle
At MaxMind, we approach fraud screening in a different way. We examine an online transaction from various angles. Our tools are not geared towards verifying the authenticity of the credit card details used for the purchase, but rather, identifying if the purchaser is the legitimate card holder. Through our analysis, we have been able to identify traits and patterns that are associated with fraudulent orders. By asking the right questions, we can provide e-commerce businesses with the necessary information to detect fraudulent orders before the payment is processed.

5. This is what you should see once installed:

Warning
BACKUP your database and files BEFORE installation. Use this contribution at YOUR OWN RISK.

Installation
With Zen Magic only one file needs to be replaced IF you want credit card orders to auto-process when the order is placed:
includes/modules/pages/checkout_process/header.php

If you want to use the credit card issuer (BIN) name and phone number fraud scoring, or if you use the default credit card module and do not store credit card numbers on the server (you e-mail the middle numbers), you will need to replace:
includes/modules/payment/cc.php
(This needs to be done to change which numbers stay on the server and which get e-mailed to you, we need the first 6 numbers to pass on to MaxMind)

If you use GoogleCheckout you need to replace:
googlecheckout/responsehandler.php
(This needs to be done so the ip address is collected from the GoogleCheckout message and stored in the database.)

The core file includes/classes/order.php has to be modified to seperate the customers ip address.
(A regex smart person could rewrite the ip address grabbing code to remove this requirement.)

All other files are added and used with Zen Magic:
admin/maxmind_orders.php
admin/maxmind_update.php
admin/images/flags/*.*
admin/includes/boxes/extra_boxes/maxmind_orders_customers_dhtml.php
admin/includes/extra_datafiles/maxmind_orders.php
admin/includes/languages/english/extra_definitions/maxmind_orders.php
googlecheckout/responsehandler.php ***Only needed if you use GoogleCheckout***
images/maxmind_ccfd.gif
includes/extra_datafiles/maxmind_orders.php
includes/languages/english/extra_definitions/maxmind_orders.php
includes/modules/maxmind/CreditCardFraudDetection.php
includes/modules/maxmind/GeoIP.dat
includes/modules/maxmind/geoip.inc
includes/modules/maxmind/HTTPBase.php
includes/modules/maxmind/maxmind.php
includes/modules/payment/cc.php ***Read note above, only needed if you want to use BIN scoring or e-mail partial credit card numbers***
includes/modules/pages/checkout_process/header.php ***Read note above, only needed if you want to auto-process orders***
