Firefox Extension Blocks Dangerous Web AttackOctober 8, 2008 – 12:07 PM
A popular free security tool for the Firefox browser has been upgraded to block one of the most dangerous and troubling security problems facing the Web today.
The latest release of NoScript, version 220.127.116.11, will stop so-called “clickjacking,” where a person browsing the Web clicks on a malicious, invisible link without realizing it, said Giorgio Maone, an Italian security researcher who wrote and maintains the program.
Clickjacking has been known for several years but is drawing attention again after two security researchers, Robert Hansen and Jeremiah Grossman, warned last month of new scenarios that could compromise a person’s privacy or even worse, steal money from a bank account.
Unfortunately, clickjacking is possible due to a fundamental design feature in HTML that allows Web sites to embed content from other Web pages, Maone said. Nearly all Web browsers are vulnerable to a clickjacking attack.
