When we want to send a message that contains only a link, like a question from the Stackoverflow network, Whatsapp bring some information from the web-site as below;
- The main question is; does this leak information about what was sent, and from who, and to whom?
We can assume that Whatsapp uses an internal browser and doesn’t send information to itself, however, that is already a leak since the user is already looked there before sharing. What about a collaborative attack, like Google and Whatsapp combined? Whatsapps see the message send and Google sees the looked site. So, does this leak information?
