I've been always worrying about using HTTPS in all sites and using secure connections in Messenger, Email, etc, because I don't want people being able to read my private info or hacking my sessions on sites, in shared networks.
However, I would like to try myself doing the same, just to see how easy it is to do what I've been worrying about.
The thing is, Wireshark can only sniff what my computer receives and sends. Or, if I make everything obviously insecure in a private network for Wireshark to be able to get the packets.
I assume that is because routers are not hubs anymore, not broadcasting anymore, sending the packets directly to the destination.
So my questions are:
1) Does it make sense at this time to worry about someone tracking what I'm doing on the Internet in a shared network?
2) If so, how do I sniff traffic from other computers in a shared network?
I'm not saying I'm going to discard the importance of HTTPS. I fully know the importance of it. However, not all sites or services provide secure connections, and those are what I worry about, avoiding using them in a shared network.
