Online Fraud: Start with the "Why"

By Yohai Einav, Senior Fraud Analyst


I have six friends that serve me true
Their names are Why and What and When
and How and Where and Who.
-- Rudyard Kipling


Why quote Kipling in an online identity blog? According to all his biographies, Kipling was never a victim of identity theft, nor did he ever write a blog.

But Kipling knew something about the 6 W's, something that we, in the security industry, often forget: starting with the "Why."


Have you noticed the phenomenon: every discussion about identity theft, security and online fraud - starts with the How and What questions:


"How do fraudsters attack banks?"
"What technologies are fraudsters using?"
"What is the damage to customers?"
"What can we do to protect ourselves?"


All good questions. But, the first thing we should ask is "why?"


"Why am I being attacked?"
"Why am I a target?"
And, of course, "why isn't my competitor a target?!"


When you think of it, all banks are good sources for money (yes, they really are!), but, for some reason, not all banks are attacked by fraudsters. As I see it, not all fraud targets are born equal: there are the preferred and the less preferred. Where do you want to be?


A good example for the "Why" is Phishing:
Phishing is a huge, worldwide phenomenon. Millions of phishing emails are sent every year and thousands of new phishing sites are created every month. But the list of entities being attacked is quite constant. And you usually see a trend of bursts of phishing attacks against a specific target.


Why?

The true cost of online fraud

Posted by Vicente Silveira, Sr. Product Manager for VIP Fraud Detection Service

The never ending parade of consumer data leakage and the inevitable fraud that follows added another participant this week with the Hannaford incident. This time, the damage amounts to 4.2 million credit and debit cards being compromised. It is early to tell all the ramifications of this incident, but the unraveling already started with the first salvo of class-action lawsuits against Hannaford.

When I see something like this happen, I'm always left to wonder: what is the true cost of a fraud incident ?

Looking back to some of the high-water mark incidents of the past we can have some hints of what the direct cost involved may look like. Take TJ Maxx for example: back in January 2007 TJ reported a 45 million (or 94 million) card compromise, which was followed by an estimated $68 million to $83 million in fraud losses on Visa cards alone. All this damage led to legal action and a settlement last September with TJ reserving more than $120 million to cover for it. Fast forward to the beginning of this week, and TJ is still in the news with a massive notification campaign that has been kicked off with mailings, magazine and newspaper adds to try to reach customers that may have had their cards compromised.

Based on all of this, it shouldn't be unreasonable to think that the direct costs associated with this fraud incident are north of $100 million dollars, specially when you include legal costs, advertising and G&A overhead to manage all the mess. All the urgent security assessments, patching and fixing shouldn't have come cheap either.

The indirect costs are harder to access but in my view even more dramatic: one can only imagine the amount of brand damage when you have to engage tens of millions of your customers repeatedly over more than one year, reminding them you didn't manage to keep their sensitive data safe. The cost goes up and is shared with all of us with the broader backlash against e-commerce and online businesses in general, where consumer confidence is melting away faster than I can say Global Warming. We are already seeing that in the polls: according to a recent YouGov survey in the UK almost half of the women in Great Britain would be ready to stop shopping and banking online in order to reduce their risk of ID fraud.

It got to a point where even corrective and preventive measures are becoming vectors for data leakage, such as this bank's attempt to notify one customer about a fraud issue in his account ending up compromising information on other people's accounts.

Sooner or later we will have to implement pro-active, stronger security measures for the broader online infrastructure, the only question is how much organizations and consumers will have to pay until that day arrives.

What's your online persona worth?

Posted by Vicente Silveira, Sr. Product Manager for VIP Fraud Detection Service


If you live in the UK, the answer would be a little over twenty thousand dollars (at current exchange rates) for the average adult internet user, a nice bounty for phishers, bot herders, malware coders and other cyber-criminals to go after.

This is based on highlights of a recent YouGov survey that estimates European Internet users are risking up to 1.6 trillion dollars by sharing personal and financial data with sites that are not adequately protected, with UK Internet users responding for a 731 billion chunk of the total amount.

What the research also suggests is that the ubiquity of social networking and other data sharing sites has increased dramatically the quantity and sensitivity of the information available on the web, with users volunteering more and more details in order to complete their profiles, make more friends or establish new connections. Many consumers are giving away their date of birth (75%), their home address (70%) and even their mother's maiden name (68%). People sharing such data may not realize that it is not too hard to aggregate all this information and use it to compromise internet banking accounts and other sensitive online applications.

That is why consumer education plays a key role in making sure users understand what is appropriate to share and where to share it. And believe it or not some of it is working, as the YouGov research shows that consumers are becoming more aware of security symbols such as the padlock (69 percent) or a security mark like the VeriSign® Secured Seal (41 percent).

Moving forward, tools such as Microsoft IE7 and EV certificates will ease the learning curve, but at the end of the day good old common sense continues to be key when deciding whether to share sensitive data online.

The Global Business of Fraud

Hi there! My name is Vicente Silveira and I'm responsible for the VIP Fraud Detection Service , or as we call it, VIP FDS, product at VeriSign.


Our team develops products that help businesses and individuals transact securely on the internet. Needless to say we have a lot of work to do.


I just spent some time in Europe talking to financial institutions and comparing notes on fraud trends here and there. One of the quick conclusions is that online criminals are sharing tools and methods on a global basis and on a scale that we haven't seen before.


One example is a modern variation of an old stock touting technique known as "Pump and Dump" , where fraudsters use e-mail spam to falsely promote a thinly traded instrument (such as a penny stock) hoping that enough people will buy it and drive the price up. The way they make money is by buying the penny stock before sending the spam and selling when the stock goes up (and before it crashes down).


Now if one feels like following investment tips from an e-mail with an anonymous robotic voice that is one thing. A different thing altogether is when criminals take "Pump & Dump" to the next level and steal your username and password, hijack your online brokerage account, sell all your blue chip stocks and use the proceeds to buy the penny stock, leaving you with some worthless equity in a tiny and obscure company. Play the video below for a CNBC report on Pump & Dump aired last year.


Over the last two years, the SEC has filed charges against several individuals in the US and abroad that used this enhanced technique to defraud online brokerage users. Since 2007 the same technique started to show up in Europe and China, as fraudsters realize they can repeat the scam throughout the globe.


While the authorities are arresting some of the suspects, the sustainable solution is for brokerages to continue monitoring suspicious trading behavior and investing in better authentication credentials.
