WhatsApp under threat?Reuters File

Before you get overjoyed by the fact that you just received a voice-calling invitation on your WhatsApp-decorated smartphone, here's a bit of reality best served harsh: The voice-calling invitation you are receiving is basically a malware and the newest way in the book to scam users.

As reports have suggested, the latest voice-calling invitation from WhatsApp is a spam message that's being used to insert malware into smartphones. As of now, a number of users have already received the fake invitation.

Furthermore, the message has already gone viral and uses to its advantage the fact that WhatsApp was recently pushing out an update for selected subscribers that would allow voice calling via the application.

The new fake message tried to imitate the roll-out from the company and was even successful in downloading malware into a number of handsets, assuring users that it was indeed the much anticipated voice-calling feature that users have been craving for since its announcement.

In order to avoid getting duped by the scammers, keep in mind that the invitation comes accompanying a link 'www.WhatsappCalling.com' that then redirects you to a website where a short survey on behalf of the popular messaging service will be conducted.

Once that survey is done and dusted, the website will then ask the user to download various applications that can and will spread malware in the phone in question. Downloading the malware-infected apps is a part of the survey and in order to complete it, you will need to download and install those applications.

In the end, as if infecting your handset isn't enough, the website will prompt the user to spread the message by sending the invitation to few other friends. Users are currently advised to stay away from any such malicious links and messages.

Stay tuned for more updates.
