Web Surfers Face Dangerous New Threat - Clickjacking

Internet and Web browser security experts are sounding the alarm about a new type of malicious attack called "clickjacking," a technique that can be used to dupe Web surfers into revealing confidential information while clicking on seemingly innocuous Web pages. Among other things, a clickjacking attack can be used to take control of a computer's Webcam and microphone without the knowledge of the user.

Clickjacking has been identified as a vulnerability for the Adobe Flash player, as well as for every major browser, including Firefox, Internet Explorer, Opera, Safari and even the newly released Google Chrome.

"It is a very serious problem," said Giorgio Maone, the author of a widely praised free Firefox extension called NoScript, which blocks potentially malicious scripts from running in the Firefox browser.

"Clickjacking is a very simple attack to build, and now that the details are out, any script kid can try it successfully," Maone warned. "There's no estimate to the number of trap sites, and it's unlikely that we will see any credible report about the number of sites using this technique, because there are literally infinite ways to implement such an attack, therefore no signature-based scanning can detect it automatically."
