9. Arrests in card scam

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 & Social
Arraigned yesterday in the thefts of credit-card and debit-card information — and more than $100,000
11. CVV2s contain:
1: Name, Address, Post/Zip code, Phone number, Name on Card, CC Number, Expiry, CVV2
2: Name, Address, Post/Zip code, Phone number, Name on Card, CC Number, Expiry, CVV2
3: Name, Address, Post/Zip code, Phone number, Name on Card, CC Number, Expiry, CVV2
14. 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
16. 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

• 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
21. What This Means In Regards to Fraud
• 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

(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
23. 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?
25. New Tools and Techniques: The 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
26. 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!
27. Identify Your Vulnerabilities
