So I've been offered the chance to go to a day long security awareness event hosted by some organization. On their site, I noticed the login box in the corner, but the site was delivered on HTTP. They probably are doing like some other sites and only using https for the actual login. I thought. So I checked the source of the page, found the form being submitted for login, and noticed 'http://...'.
I'm wanting to bring this to my coworkers' attention, but first I want to be sure that they actually are sending it over http. Is there any other way to verify the connection is going over http (other than setting up a MITM attack on myself, which I'm pretty sure would cause the network admin to express great... displeasure towards me)?
