Keep an eye out for scam emails that appear to be from WhatsApp, or you could end up with a nasty case of malware on your iPhone or Android device.
The offending emails have been reported with subject lines such as "new voice message", “a brief audio recording has been delivered”, “a short vocal recording was obtained” or "an audio memo was missed".
"Cybercriminals are becoming more and more like marketers, trying to use creative subject lines to have unsuspecting emails be clicked and opened to spread malware," said Director of Comodo Antispam Labs, Fatih Orhan.
Once the email is opened and attached virus downloaded (it will be in a compressed ZIP file), you'll have yourself an infected phone. The virus adds itself into an auto-run of the computer's registry, and duplicates throughout system folders. Not fun.
WhatsApp users should treat any emails with suspicion, since notifications for the messenger platform are only ever delivered in the app.
