WhatsApp Vault Secures Voice Message

This CGI advertisement features a building undergoing a dramatic transformation. In a timelapse sequence, all its windows close, followed by a wave of grey particles rising from the ground up, dissolving the building's outer layer and leaving only its structural beams.

A metal gate then closes over the scene, which subsequently opens to reveal a vault. As the vault door shuts, a voice message enters, and a WhatsApp advertisement on the side promotes secured messaging.
