A spam message is being used to download malware on smartphones, the message shows a fake invitations to download the voice calling feature on WhatsApp. A number of people reported that they got an invitation to try-out the calling feature in WhatsApp. The message is already viral and is using the fact that WhatsApp had recently pushed an update for few subscribers that allowed voice calling via the application. The message tried to mimic this move and was successful in downloading malware in the name of the much anticipated voice-calling feature.
The invitation comes with a link www.WhatsappCalling.com that takes you to a website where a short survey is conducted, and once that survey concludes the website will ask the user to download various applications that can spread malware in the phone.
