IE9 Best at Protecting Against Socially-Engineered Malware

NSS Labs recently tested all of the current (or at least current at the time) Web browsers to see how well each detects and prevents socially engineered malware attacks.

The NSS Labs press release about the study explains:

Socially engineered malware (SEM) remains the most common security threat facing Internet users today, claiming one third of internet users as victims. These attacks pose a significant risk to individuals and organizations by threatening to compromise, damage, or acquire sensitive personal and corporate information. European and American users have found themselves particular targets of malware authors over the last 12 months. North America has consistently been the primary host of malicious URLs, while users in Asia have been victims of the greatest number of malicious URLs.


Cybercriminals are taking advantage of the implied trust relationships inherent in social networking sites (Facebook®, MySpace™, Badoo, StudiVZ, Skyrock, LinkedIn®, renren, Kaixin001 (a.k.a. Happy Net), 51, Multiply, Cyworld, Orkut, Mixi, etc.) and user-contributed content (blogs, Twitter™, etc.) which allow for rapid publishing and anonymity. Furthermore, the speed at which these threats are “rotated” to new locations poses a significant challenge to security vendors.

NSS Labs found, “With a unique URL blocking score of 99.9% and over-time protection rating of 99.2%, Internet Explorer 9 was by far the best at protecting against socially-engineered malware.”
