Arrests in card scamWednesday, February 28, 2007

By Paul Grimaldi

Journal Staff Writer

Arraigned yesterday in the thefts of credit-card and debit-card information — and more than $100,000

The men allegedly stole the information by

switching out checkout lane keypads with

one of their own machines and then

retrieving the units a few days later so

they could copy the account data. To

achieve this, they took shelf stocking

positions at the supermarket, which gave

them legitimate access to the facility

during late hours in the evening. They

recorded the stolen information on blank

bank cards that they used to get money from

ATMs in the area, the police said.

Organized Crime

Malware & Botnets

• Easy to find & customizable by user

• Designed to monetize fraud not disrupt systems

• Utilizes phishing attack info

• Prevalent in online advertising & affiliate fraud

• Very low detection & apprehension rate

• Very high ROI rates

• High rate of mutation

Moving the Cash

Attacks on Specific Payment Instruments

• As electronic payments evolve, criminals evolve their targets and their

strategies

• Specific payment instruments have come under significant attack

– Alternative payment: PayPal, Bill Me Later, etc.

– Gift Card (Plastic and Virtual): Schemes used in, both, the acquisition and

redemption of gift cards

– Private Label cards

• Merchants are often “two steps behind” the criminal after launching or

adjusting payment strategies

This is what it’s come to…

• Merchant sample includes 3 very large, established major retailers with significant transaction volumes and private

label portfolios

• Includes CNP Fraud rates for transactions taken place in 2008, with the exception of Retail “B”, whose statistics are

from July to December 2008

• Base on Retail Decisions merchant assessments, April 2009 (delay introduced to allow for confirmed

fraud/chargeback resolution window)

• “Fraud Rate” is defined as known-fraud, but not necessarily chargebacks. Some fraud is detected and denied before

a chargeback occurs. Actual chargeback rates for Other Card Types is significantly lower than reflected above

The Fraud Lifecycle

• Credit card fraud continues to become more of an organized, professional crime

– the case studies prove it

• CNP fraud continues to aggressively increase. As more countries adapt Chip

and PIN solutions, fraud will continue to migrate from CP to CNP channels

• APACS 2007 Fraud Study: For the first time, more than 50% of fraud was CNP

fraud. Update with new state

• As other countries implement Chip and PIN solutions, both CP and CNP fraud

will increase in non-Chip and PIN geographies

• ID Theft continues to increase, replacing counterfeit schemes, which are no

longer valid in Chip and PIN geographies

• Since fraud is aggressively expanding, legacy fraud prevention techniques are

becoming less and less effective

What This Means In Regards to Fraud

Website, etc.

ACCEPT

CHALLENGE

ORDER(Manually Review)

Fraud Prevention System and Tools

(Proprietary or

Outsourced)

~2% Of All Orders 2%-8% Of All Orders

(Where Applicable)

• Challenges or outright Deny categories may not work for all types of merchants

• Merchants must find the balance:

• Too many manual reviews = too much staffing cost

• Too many outright denies = too many false positives

• No Fraud Prevention system is perfect: You will have false positives. You will

require manual review. Today’s strategy is to let the Fraud Prevention system

identify ~95% of all good and bad orders and manually review the rest

Key Metrics Merchants Must Track:

• Manual Review Rate (“Outsort Rate”) - % of orders reviewed by a person before shipped or cancelled

• Outright Deny Rate - % of orders rejected by the fraud system without performing a manual review

• Fraud Rate – Overall percentage of fraud, usually measured in % of overall transactions and % of $ value

• Customer Insult Rate – Falsely identifying good customers as fraudulent OR degrading service to good

customers as a result of slow/cumbersome fraud processes (e.g. manual reviews take so much time to

complete that shipping windows are missed)

• Revenue at Risk – How a particular fraud strategy could affect revenue

When This Happens: This Could Happen:

Manual Review Rates Increase Fraud Rates - Decrease

Staffing Costs - Increase

Revenue at Risk - Decrease

Customer Insult Rate – Potential to increase (slower order turnaround)

Scalability – becomes challenging (Double my orders = Double my staff??)

Manual Review Rates Decrease Fraud Rates - Increase

Staffing Costs - Decrease

Revenue at Risk – Potential to increase

Customer Insult Rate – Potential to increase (due to higher deny rates)

Hard Deny Rates Increase Fraud Rates - Decrease

Staffing Costs - Decrease

Revenue at Risk – Increases (Much more false positives)

Customer Insult Rate – Increase

Should you accept it? Should you outright deny it? Should you manually review it?

The "More Tools Create Greater

Complexity" Challenge

Some technologies don’t fit our existing

paradigms

Some technologies are expensive

Some address very specific fraud

scenarios

More tools and technologies can actually

make decision making more difficult

Some may require additional

customer data, such as

SSN/last 4 or ask personal

validation questions

Cost per transaction increases

when more techniques and

technologies are added to the

suite of fraud tools

Fraud Evolves. Will these be

valid in 2 years? 1 year? 6

Months?

Could lead to increased manual

review costs, false positives

and customer dissatisfaction

New Tools and Techniques: The Challenge

Merchant vs. Issuer Fraud Prevention

Merchant Fraud Prevention

• Screening is transaction-centric

• Primary goal is to protect loss of goods

while staying out of compliance programs

(e.g. Visa RIS)

• Primary focus on CNP channels

• Historical perspective on cardholder is

relatively limited

• Transaction Data set is very robust –

Who? What? When? How?

• More focus on real-time screening

• Many more detection tools exist due to

robust CNP data set

Issuer Fraud Prevention

• Screening is more account- centric

• Primary goal is to protect losses within

issuing portfolio

• Not primarily focused on CNP – in fact,

CNP is often removed from some

screening models

• Historical perspective on cardholder is

comprehensive

• Transaction Data set is limited: Basic

account and transaction details

• Less focus on real-time screening

(although this is changing)

• Certain tools can be deployed much more

effective (e.g. neural networks)

Consolidated Merchant / Issuing fraud prevention systems do not exist today!

• System and IT

• Business model weaknesses

• Defined payment strategy

• Product Delivery

• Customer service and business policies

• Systems designed for the future

• Manage to Total Cost of Payment
