Michael Mosbey sent us a link to a website that attempts to scare people into purchasing a credit report. The website, pictured below, reminds the visitor of the relatively recent Epsilon data breach. The goal is to persuade the person into proceeding to another site that is being promoted. This looks like a technique to make money through affiliate marketing.

Fraudulent URL: www. financialalertssystem. com/5/t/14.php?engsec=10&target=example.com (don't go there)

To urge the person to act right away, the website uses a bit of JavaScript to dynamically generate the date during which the offer is available. This allows the website to always present the current date, regardless of when the page is accessed.

The page is written to assist the attacker in targeting multiple domains. It accepts the targeted organization's name as the "target" parameter. For the screenshot above, we used "example.com", so the page stated "Important Information for Example.com Customers."

The page also presents the following (entertaining) disclaimer:

"2011 All right reserved. This site is not sponsored by or affiliated with Example.com. Example.com has not authored, participated in, or in any way reviewed this advertisement or authorized it. Terms and conditions apply, see service providers's site for details. This site is an advertisement. This website, and any page on the website, is based loosely off true stories, and is a fictitious account. Compensation is received for clicks on or purchase of products featured on this site..
