Hi guys,

i installed fiddler, rooted my android and started debugging.

Fiddler captues the traffic from chrome and some other apps. Nice!

Then i started whatsapp but there was no connection in fiddler.
I send a message, my other phone got it but still no message in fiddler.
Then i clicked on the profile picture and there was only a "CONNECT pps.whatsapp.net:443 HTTP/1.1" in fiddler.

Why i fiddler not showing the traffic?
I there is cert pinnig or something like that, whatsapp should not work but its working.

Hi Andy,

 

It's not officially confirmed but based on some threads posted online it seems that WhatsApp application uses both certificate pinning and also uses their own end-to-end encryption. So that said, it would make sense that you won't be able to capture traffic that goes through the application.
