(NOTE: I've read other similar questions, but I'm not at all certain about this, therefore I'm asking.)
I travel a lot, and I generally use public WiFi spots and hotels/hostels/boarding houses etc. access points.
I'm a reporter. Sometimes I send my communications to email services and websites which don't use SSL cryptography (no https, just http), and though I KNOW this is not smart, I have no alternative.
What I want to know is if someone locally sniffing the network could read what I send to unprotected (no https) websites. If I send multimedia, pictures, audios etc., can they see/listen to them? Can they see what sites exactly I'm loading?
If so, what would take them? Just being connected to the same network? Having direct access to the router?
Is there anything I can do about it?
Again, I'm talking about people using the same network, snooping locally, and thinking about the data just after it leaves my PC and after it leaves the end node.
