It has also been reported by researchers that WhatsApp group chat might not be so secure and a malicious server could allow someone to be secretly added to the group.

Speaking to Wired, one of the researchers said: "The confidentiality of the group is broken as soon as the uninvited member can obtain all the new messages and read them". Currently, only the administrator of the group can invite new members, but the platform doesn't use authentication for an invitation its own servers can't spoof. WhatsApp is a widely used messenger and is available in more than 60 different languages which include 10 Indian languages.
