Epsilon_SigEp_NV_Alpha_03_CCFlickrSpot Quiz: What does the word epsilon mean to you? It is the fifth letter of the Greek alphabet. As I recall, in its lowercase form, epsilon stands for elasticity, among economists. There might even be a fictional spy named Epsilon.

I’ll bet that up until a few days ago you didn’t know that Epsilon was also the name of a company that has exposed millions of Americans (including you, most likely) to the increased risk of imposter fraud, a crime that made it to the Federal Trade Commission’s top ten complaints list this year for the first time. Epsilon is a unit of Alliance Data that collects consumer information from hundreds of corporate clients to manage their email marketing campaigns.

On April 1st, Epsilon posted a terse announcement on its corporate website, which set off a media frenzy and confirmed, yet again, the end of the Age of Digital Innocence:

IRVING, TEXAS – April 1, 2011 – On March 30th, an incident was detected where a subset of Epsilon clients’ customer data were exposed by an unauthorized entry into Epsilon’s email system. The information that was obtained was limited to email addresses and/or customer names only. A rigorous assessment determined that no other personal identifiable information associated with those names was at risk. A full investigation is currently underway.

Apparently, an unknown cyber ninja (or coven of ninjas) had efficiently and maliciously gained unauthorized access to the Epsilon system and caused, according to Michael Kleeman, a network security expert at the University of California, San Diego, a “massive hemorrhage” of what has heretofore been considered non-personal identifying information, yet now is viewed by a growing number of privacy experts as the Social Security Number in the Digital Age—the email address combined with a name. In other words, the data that consumers provided to many large companies, such as J.P. Morgan Chase, Citibank, Kroger, Target, Best Buy, Disney Destinations and Verizon, could now be in the hands of guys we would never want to friend on Facebook.

If you didn’t know anything more than that, it would be horrifying enough. After all, despite thousands of privacy policy disclosures and enormous media attention, most folks don’t know (or don’t want to know) that information provided to trusted financial institutions, service providers or retail stores is shared with other companies. Again, I’ll bet most Americans didn’t know that there even was a company called Epsilon. But worst of all, we still don’t know, even now, how much information Epsilon really has, or which information was truly hacked. It was publicly announced that, not to worry, only email addresses were stolen. I received several frantic emails from banks with which I have relationships assuring me that only my email address was no longer secure.

Let’s make the salutary (and perhaps facile) assumption that the press releases and email alerts are accurate. So all the bad guys have is our email addresses and our names, right? No biggie, right? Well, not exactly. The problem is that our email addresses are also our user IDs on many websites. Few people are willing to change their email addresses, because too many other people would have to be notified. So in my case, I will have to strengthen my already strong passwords—again.

Heck, it’s gotten so complicated that my current password contains several letters (some upper-, some lowercase), a few numbers, and symbols I have inserted in the place of letters (and forget about the punctuation marks I must now liberally sprinkle throughout). It seems like no password—even those reminiscent of chemical compounds—is enough anymore. (To say nothing about the “secret questions” many sites rely upon in lieu of forgotten passwords. In the Facebook age, it’s not difficult to figure out someone’s high school or mother’s maiden name, so users should establish answers to these as secondary passwords or responses completely unrelated to the question prompt.)

Hello, Reader!

Thanks for checking out Credit.com. We hope you find the site and the journalism we produce useful. We wanted to take some time to tell you a bit about ourselves.

Our People

The Credit.com editorial team is staffed by a team of editors and reporters, each with many years of financial reporting experience. We’ve worked for places like the New York Times, American Banker, Frontline, TheStreet.com, Business Insider, ABC News, NBC News, CNBC and many others. We also employ a few freelancers and more than 50 contributors (these are typically subject matter experts from the worlds of finance, academia, politics, business and elsewhere).

Our Reporting

We take great pains to ensure that the articles, video and graphics you see on Credit.com are thoroughly reported and fact-checked. Each story is read by two separate editors, and we adhere to the highest editorial standards. We’re not perfect, however, and if you see something that you think is wrong, please email us at editorial team [at] credit [dot] com,

The Credit.com editorial team is committed to providing our readers and viewers with sound, well-reported and understandable information designed to inform and empower. We won’t tell you what to do. We will, however, do our best to explain the consequences of various actions, thereby arming you with the information you need to make decisions that are in your best interests. We also write about things relating to money and finance we think are interesting and want to share.

In addition to appearing on Credit.com, our articles are syndicated to dozens of other news sites. We have more than 100 partners, including MSN, ABC News, CBS News, Yahoo, Marketwatch, Scripps, Money Magazine and many others. This network operates similarly to the Associated Press or Reuters, except we focus almost exclusively on issues relating to personal finance. These are not advertorial or paid placements, rather we provide these articles to our partners in most cases for free. These relationships create more awareness of Credit.com in general and they result in more traffic to us as well.

Our Business Model

Credit.com’s journalism is largely supported by an e-commerce business model. Rather than rely on revenue from display ad impressions, Credit.com maintains a financial marketplace separate from its editorial pages. When someone navigates to those pages, and applies for a credit card, for example, Credit.com will get paid what is essentially a finder’s fee if that person ends up getting the card. That doesn’t mean, however, that our editorial decisions are informed by the products available in our marketplace. The editorial team chooses what to write about and how to write about it independently of the decisions and priorities of the business side of the company. In fact, we maintain a strict and important firewall between the editorial and business departments. Our mission as journalists is to serve the reader, not the advertiser. In that sense, we are no different from any other news organization that is supported by ad revenue.

Visitors to Credit.com are also able to register for a free Credit.com account, which gives them access to a tool called The Credit Report Card. This tool provides users with two free credit scores and a breakdown of the information in their Experian credit report, updated twice monthly. Again, this tool is entirely free, and we mention that frequently in our articles, because we think that it’s a good thing for users to have access to data like this. Separate from its educational value, there is also a business angle to the Credit Report Card. Registered users can be matched with products and services for which they are most likely to qualify. In other words, if you register and you find that your credit is less than stellar, Credit.com won’t recommend a high-end platinum credit card that requires an excellent credit score You’d likely get rejected, and that’s no good for you or Credit.com. You’d be no closer to getting a product you need, there’d be a wasted inquiry on your credit report, and Credit.com wouldn’t get paid. These are essentially what are commonly referred to as "targeted ads" in the world of the Internet. Despite all of this, however, even if you never apply for any product, the Credit Report Card will remain free, and none of this will impact how the editorial team reports on credit and credit scores.

Your Stories

Lastly, much of what we do is informed by our own experiences as well as the experiences of our readers. We want to tell your stories if you’re interested in sharing them. Please email us at story ideas [at] credit [dot] com with ideas or visit us on Facebook or Twitter.

Thanks for stopping by.
