Mozilla’s FireFox made Internet Browser tabs popular and Internet Explorer followed suit with quicking adopting tabs into their web browser. As with all technology, a new threat that emerged was “Tabjacking”. Tabjacking emerged as a threat in early 2007. It refers to hackers introducing malicious code into your computer’s borwser where one of the browser tbas will fall under their control and be directed to a potentially malicious website. They can also use the hijacking or tabjacking to display adware and other annoyances on your computer.
Internet Browser Tabs
Mozilla Firefox made web surfing with multiple tabs popular with Internet surfers. Firefox was the first browser to incorporate tabs and Microsoft’s Internet Explorer followed suit with IE 7. It reduces the number of browser windows that you have to open on your computer when surfing across multiple websites and can take up less memory on your computer by not opening as many concurrent computer processes.
How Tabjackers Gain Control of Your Browser’s Tab
Internet Browser tabs are another potential Internet Browser exploitation target. If a hacker can gain control of a browser tab on your computer’s Internet Browser, then they can use the “Tabjacked” tab to load computer malware on your computer, or display variants of “pop-under” or “pop-up” advertisements. This type of ad doesn’t have a unique name yet…maybe “tabvertisement”? This is just an annoyance, however, as the real danger lies in opening a malicious website that can inject malicious code on your computer such as Spyware or Trojan virus downloaders than can serve as gateways to additional computer malware being installed on your computer without your permission. Tabjackers could also display “fake” webpages for commonly used banking and other websites where you might be tricked into entering your credit card or other financial information. Tabjacking normally occurs from hackers taking advantage of Browser security vulnerabilities on computers that are not running up-to-date anti-virus software or out of date operating systems.
How to Defend Against Tabjacking
The best way to defend against Tabjacking is to keep your Operating System and Web Browser up to date with all current software updates and to run current anti-virus protection. Once you are infected, you will likely notice an increase in adware and spyware being run on your computer which requires a greater level of effort to remove than keeping your browser from being tabjacked in the first place.
