Introduction
In this tutorial, we would like to
share with merchants some common techniques to pinpoint red flags of credit
card frauds. Our goal is to cut down all frauds and chargebacks.
John is an online merchant selling
watches. Below is one of his typical order. Everything looks fine to him but we
would like to highlight some important information to help him make an informed
decision.
IP Address
The IP address is from an anonymous
web proxy service. It allows the user to hide their actual IP address but still
perform an order submission. In this case, the actual user IP address is
unknown and we only know the proxy server's IP address.
If we analyse the user’s IP address,
it is located in a different country which is 1,000 miles away.
Amount and Quantity
The order and quantity are also
above average transaction values. Fraudster will usually order large quantities
of items to maximize their returns.
Addresses
The shipping address is being
listed as one of the forwarding service providers. The
actual item will be forwarded to another address for collection upon
fraudster’s further instructions.
The shipping address, billing
address and IP address locations are all totally different. In this case, the
fraudster is using a proxy server, mail forwarder and stolen credit card to
avoid tracking.
Email Domain
The order is being submitted using
a disposable email address. The email address is easy to setup, anonymous and
temporary.
Username and Password
The user name and password is too
simple and generic. Fraudsters usually apply easy-to-remember account
information.
Credit Card
The credit card number has been
blacklisted due to prior exposure in public area. The fraudster purchased this
credit card information from underground trading forums.
BIN and Issuing Bank
The BIN number and issuing bank
name do not match. Fraudsters usually only have partial credit card information
except the issuing bank information.
There are many other techniques
that are not readily apparent when looking at the order forms such as
transaction velocity and device fingerprints, both of which can also unmask a
serial fraudster.
If you do not have the time to
process these techniques for all orders, you can consider the FraudLabs Pro fraud service which is
free for small businesses.

credit card transactions for online frauds. It accepts online transactions data
via its open API. Fraud screening engine analyzes transactions parameters and
returns its fraud analysis. Merchants can then decide on the next course of
action based on the fraud distribution score or custom rules by conditions.
