SECURITY CONCERN

Someone sent me a voice message via Whatsapp. I was on my driveway when I got the message. My wife who is in the house was on whatsapp talking with her brother and the voice message I received also went in the conversation she was having. The sender doesn't know my wife, in fact he is in Africa. Technically, the same voice message went to 2 different devices. 

Clues:

- My wife and I have Iphones

- My wife and I have different icloud accounts

- My wife and I have cricket as phone service provider

- My wife was not connected to the home wi-fi, but I was.

- My wife's bluetooth was disconnected from my car

A very strange and scary scenario. Anyone experienced this before? If this is a bug in whatsapp application, it is a problem
