It looks like spammers have found a new service to host their sites in. For several days, Trend Micro threat researchers have seen spammed messages advertising various prescription medications.

As expected, clicking any of the links in the email will lead you to the spammers’ website. Unusually, however, the links are hosted on blogs that are hosted by Yahoo!

The presence of Yahoo!’s logo on these sites may well be interpreted by some users either as an endorsement or as a sign that the site is legitimate.

Trend Micro product users need not worry, however, as the spammed messages are blocked by the Smart Protection Network, along with user access to the spam sites.
