Malware researchers have notified Google working since long time on blocking the tap-under behavior in Chrome. Google commonly considers tab-under behavior at the time when an unsuspecting user is scrolling or tapping a page, but the site duplicates or clone the current page in some another tab and displays an ad or a new website in the page the user was initially going through.
Experts reported Crooks Exploiting Tab-under for displaying ads and redirecting users to other sites
Website owners and advertisers exploits tab-unders for generating ads and rerouting users to several undesired sites. Telemetry accommodated by Google unveiled that majority of the original pages (now displaying ads or another website) never get engaged with again. This exercise provokes the Google engineers to start working on a track to address tab-unders last year in the November.
Google discloses three distinct ways its currently looking at for the purpose of dealing with tab-unders in Chrome.
Among the three, first and the second one have been notified utilizing the existing Chrome framebusting detection framework for displaying an alert inside the page. The warning appears like so :
Now though initially both the proposals appears but as a matter of fact, are distinct from each other. The difference between the two is that the first proposal suggests displaying the warning on the original page before a new tab gets created, while on the other hand second recommends that the Chrome should close the original tab immediately and should display the warning on the new page.
Google Chrome engineers have been notified currently favoring the first proposal, since the second one might mean for allowing the creation of a new tab which does not necessarily hold the previous page’s navigational history, breaking the Back button.
Google’s third suggestion has been reported proposing to enhance the existing Chrome pop-up blocker and add support regarding tab-unders.
