WhatsApp Messenger is a widly-available, cross-platform proprietary instant messaging subscription service. It allows users to communicate via text messages and to share a wide variety of content and data, such as videos and location, without incurring text messaging fees. WhatsApp was acquired by Facebook in February 2014.
WhatsApp makes use of the following ports; 4244,5222,5223,5228,5242
When it cannot communicate on those ports it fails over to using ports 80 and 443.
Block either all incoming and outgoing, or just outgoing communications on ports 5244,5222,5223,5228,5242.
You will want to add the follow addresses to either the invididual groups blacklist, or the global blacklist.
Some of these ports are used for other popular services and will disable them as well
Port 5222 & 5223 are used for XMPP communication
Port 5228 is used for HP Virtual Room and Google Play
