How Tabjacking Works

The introduction of having multiple tabs to be opened at the same time exposed a vulnerability that can be exploited by malicious programs to infiltrate in your computer systems. On opening a new tab, the malicious code/scripts are automatically executed to “hi-jack” the newly opened tab window. These compromised tabs will then show or load the unsolicited content from the associated website. Tabjackers may also introduce harmful viruses and worms that could infect your PC. It is generally hidden inside the legitimate web content and hence detection of such invasions is quite difficult.

This technique is employed by unlawful web companies to make profit in the overgrowing web market. This type of threat is now being examined by web security experts come-up with a solution to effectively countermeasure this flaw.
