Following our warning, last week, of the possible scams related to the approaching Valentine’s Day, it’s no surprise that today we’ve seen another new Valentine theme come up–hosted on the fast-fluxing Waledac botnet. If a user were to follow the link in these spam emails–and please don’t do that!–a web site like the following would appear:

A picture with two adorable Shih Tzu puppies is wishing a Happy Valentine’s Day. The text of the lure is advertizing a “Valentine Devkit” named loveexe.exe or start.exe. And regular readers can guess it already: This is a social-engineering trick to convince users to download the real threat. Don’t click the link to the executable or you will end up with malware.

A close look into the website’s source code doesn’t currently reveal any additional drive-by infections nor downloads (but that can change quickly), as seen in past Waledac (or “Storm”) themes. Coverage of this particular malware variant is in the 5522 DATs, plus blocked by Artemis, plus blocked at the (former Secure) Web Gateway as well.
