Check out this presentation by Emily Stark from the Usenix Enigma 2019 conference.
In a security professional’s ideal world, every web user would carefully inspect their browser’s URL bar on every page they visit, verifying that they are accessing the site they intend to be accessing. In reality, many users rarely notice the URL bar and don’t know how to interpret the URL to verify a website’s identity. An evil URL may even be carefully designed to be indistinguishable from a legitimate one, such that even an expert couldn’t tell the difference!
In this talk, I’ll discuss the URLephant in the room: the fact that the web security model rests on users noticing and understanding URLs as indicators of website identities, but they don’t actually work very well for that purpose. I’ll discuss how the Chrome usable security team measures whether an indicator of website identity is working, and when the security community should consider breaking some rules of usable security in search of better solutions.
