So I was watching some Backtrack learning videos and similar stuff, and noticed how there is always talk about getting people's information. For example if someone using unsecured WIFI you can see what pages he is browsing of even steal his Facebook session.
So as far as I understand, hacker cannot get any real value from seeing that information. Even if they steal my Facebook session and post some nonsense, they gained nothing out of it material wise, right? I mean they cannot steal my Paypal credentials because they are encrypted, all they can do is access stuff which is not that important to me in the first place.
Are there any real life examples, where hacker can get some real benefit apart from getting password to random forum or just causing harm to other person?
