A new spam run is on the loose, misusing the global economic crisis as its social-engineering vector. Consumers looking for a bargain should take care, because the bad guys exactly want to fool people trying to save some money these days. Spam mails promoting bargains, which could help in the recession, are hitting the inboxes right now.

When users follow a link in such spam mails–but please don’t do that!–a website like the one below appears:

After the Valentine’s Day theme, the malware authors behind the Waledac botnet changed their lure to promote free coupons, pretending to “save” consumers a lot of money. The text states: Exclusive sale coupons and deals at over 100 000 stores in <City>, <Country>. You can find these amazing sale offers and coupons ONLY HERE! You can download free online and printable coupon list. In our list there are most popular stores, restaurants and companies in <City>, <Country> with discounts up to 95%. We help you to survive this crisis! The coupon list is named “couponslist.exe,” “sale.exe,” or “print.exe”–and, in fact, is malware.
In economically hard times, the malware authors do not rely only on clever and timely social engineering, they also include a malicious IFRAME in the website that refers to malicious code trying to exploit unpatched computers with an additional drive-by infection. Furthermore, the website is craftily designed. The bad guys are using geo-location services to better target their audience. So when someone connects to the website, it determines the geographical location on the fly and presents the actual location in the website texts. When a victim sees coupons for exactly his town, this will increase the demand for the bargain list.

As a last piece of advice we can only stress again that consumers should always take care with offers that look too good to be true–even more so in the hard times of a global economic crisis. Please also refer to our predictions for 2009 “Cybercrime, Online Threats, and the Recession.”
