If you detect that you are at the wrong URL, or that something is amiss on a page, the chase is up. You've escaped the attackers. In fact, the time that wary people are most wary is exactly when they first navigate to a site.</span></span></div> <div> <span class="Apple-style-span"><span id="7140679708706166316"><br /></span></span></div> <div> <span class="Apple-style-span"><span id="7140679708706166316">What we don't expect is that a page we've been looking at will change behind our backs, when we aren't looking. That'll catch us by surprise.</span></span></div> <div> <span class="Apple-style-span"><span id="7140679708706166316"><br /></span></span></div> <div> <span class="Apple-style-span"><span id="7140679708706166316"><br /></span></span></div> <div> <span class="Apple-style-span"><span id="7140679708706166316"><b>How Phishing Attack Using Tabnabbing Works</b></span></span></div> <div> <ol> <li style="margin: 0px 0px 0.25em; padding: 0px; text-indent: 0px;"><span class="Apple-style-span"><span id="7140679708706166316">A user navigates to your normal looking site.</span></span></li> <span class="Apple-style-span"><span id="7140679708706166316"> <li style="margin: 0px 0px 0.25em; padding: 0px; text-indent: 0px;">You detect when the page has lost its focus and hasn't been interacted with for a while.</li> <li style="margin: 0px 0px 0.25em; padding: 0px; text-indent: 0px;">Replace the favicon with the Gmail favicon, the title with "Gmail: Email from Google", and the page with a Gmail login look-a-like. This can all be done with just a little bit of Javascript that takes place instantly.</li> <li style="margin: 0px 0px 0.25em; padding: 0px; text-indent: 0px;">As the user scans their many open tabs, the favicon and title act as a strong visual cue—memory is malleable and moldable and the user will most likely simply think they left a Gmail tab open. When they click back to the fake Gmail tab, they'll see the standard Gmail login page, assume they've been logged out, and provide their credentials to log in. The attack preys on the perceived immutability of tabs.</li> <li style="margin: 0px 0px 0.25em; padding: 0px; text-indent: 0px;">After the user has entered their login information and you've sent it back to your server, you redirect them to Gmail. Because they were never logged out in the first place, it will appear as if the login was successful.</li> </span></span></ol> </div> </div> <div> <div> <span class="Apple-style-span"><span id="7140679708706166316">In this attack, the phisher need not even change the Web address displayed in the browser's navigation toolbar. Rather, this particular phishing attack takes advantage of user trust and inattention to detail, or what Raskin calls "the perceived immutability of tabs." Then, as the user scans their many open tabs, the favicon and title act as a strong visual cue, and the user will most likely simply think they left a Gmail tab open.</span></span></div> <div> <span class="Apple-style-span"><span id="7140679708706166316"><br /></span></span></div> <div> <span class="Apple-style-span"><span id="7140679708706166316">"When they click back to the fake Gmail tab, they'll see the standard Gmail login page, assume they've been logged out, and provide their credentials to log in," Raskin explained.
