Criminals are smart enough to skip any of that -- they'll trick you into opening a site that has the "same" domain and looks the same, except that the domain uses a Unicode character that is just a tiny bit different from the real one. (Thank you ICANN!) I get junk email from them every day. Even if just 1 out of 50 people fall for this, they get a good payout.

And that's just one of the many possible scenarios. When you control someone else's Internet, there is a lot of things you can do. Google's certificate transparency is going to help a lot here, but only as much as what happens in a browser.
