PIC: If you receive an e-mail like this one from WhatsApp, DO NOT open it

Security experts are warning against a cyber attack that could result in access to victims’ personal files.

WhatsApp users have been warned not to open e-mails purporting to be from the mobile messaging app that could trigger a virus giving access to users' personal data. Researchers at Comodo Antispam Labs (CASL) have identified a new malware attack targeted specifically at businesses and consumers who might use WhatsApp that uses e-mails to spread malware when the “message” is clicked on. The e-mails, which appear in a similar format to the picture below, have been cleverly branded to make it seem as if they have been sent by WhatsApp. As is evident in the sender’s address line, they bear no association with a messaging app that is used by millions of people worldwide.
