Hope this helps shed some light on what could be going on, but answer is absolutely right, it is a threat and it is recommended to always keep your browser updated in order to protect yourself.Īdditionally, clickjacking can also provide the attacker with specific information about you. Unfortunately, in the malicious case of clickjacking attacks, the perpetrator gets paid and the advertiser's ad is never seen (though is inadvertently clicked on). Generally clicks tell the advertiser that the ad (impression) was seen and interacted with by a real human visitor, and the advertiser rewards the publisher (the site that hosts the ad) with payment for serving the impression. Ordinarily when I detect this kind of behavior the clickjacking is used to falsely attribute your legitimate attempt to close a window with an advertising click, which essentially registers a click-through event on the would-be-visible ad. See this OWASP page for more information. What I believe you are referring to is a practice known as clickjacking, and this is sadly quite a common practice.
