Spam through Yahoo Groups

At the beginning of this year we were writing that Google hosts Spam on its “Google Docs” portal. Spam hosted on Google’s Groups is nothing new.

We have received now a spam hosted on Yahoo’s Groups. The difference between Yahoo and Google is that Yahoo removed the spam website (for meds) within hours after the spams were spread in the wild.

So, one point for Yahoo.

The emails contain nothing but one single URL to the Yahoo groups directory, pointing to a random generated name. You need a Yahoo account and there is also a CAPTCHA quiz when one tries to create a group.

Either the spammers have solved those CAPTCHAs themselves or they used tiny “games”. Those games are offered for download to unsuspecting users and usually show women getting undressed. Each time you solve a CAPTCHA in such games, the women is undressing more clothes.

Please don’t play these games, you’re helping spammers to create fake accounts at popular services that way.
