The word not only sounds like hi-jacking but has similar connotations as well. This new threat refers to the attack on the browsers. By exploiting vulnerabilities present in a browser a hacker can take control. Next, the victim can be duped into clicking on a link. that would lead to a malicious website. Such a website might inject malicious code on the system. To the victim it would appear as ifhe were clicking on something innocuous like a picture. Such an attack could be compared to cross-site injection or any other injection technique that has harmful consequences. At present there is no solution to combat this threat but as it uses graphics as a shield to hide its malicious content, switching to a browser that supports text only can be a solution (very difficult in the current scenario). However, research is underway to to come up with a more practical and viable solution.
