Survey scammers and adware peddlers continue to advantage of the interest Whatsapp users have in the quietly rolled out Free Voice Calling feature. According to security researchers, both English-speaking and Arabic-speaking users are being targeted. The lure comes via a Whatsapp message: a message saying that the user has been invited to try “Whatsapp Calling"” and to visit a particular site (www[dot]whatsappvoiceplus[dot]com) to activate the feature. The site first instructs them to invite ten friends. Once they do it, they are asked to complete a survey. Upon clicking on “Take the Survey” will load up a survey page, which would either present a typical selection of survey questions or give the Whatsapp fan a “Not available in your region” message. In another approach, scammers are trying to get users to install adware by offering “updated” or cracked versions of the app that apparently have the free calling feature enabled. The offered file is a Windows executable whereas Whatsapp is available as an app only for mobile users.
