Internet Explorer 9 offers the best protection against socially engineered malware according to the latest tests performed によって NSS Labs focused on European users.

The results of NSS Labs’s “Web Browser Group Test Socially-Engineered Malware - ヨーロッパ Q2 2011” レポート are conclusive with 前 findings of the testing outfit, which consistently highlight IE as offering the best protection against socially engineered malware, even though Microsoft rivals contest the conclusions.

In the latest round of testing, NSS Labs looked at Google Chrome 10.0.648.204, Windows Internet Explorer 8 (build 8.0.7600.16385), Windows Internet Explorer 9 (build 9.0.8112.16421), Mozilla Firefox 4.0, Opera 11.01 Build 1190 and Safari 5.0.5(7533.21.1).

“With SmartScreen enabled and Application Reputation disabled, IE9 achieved a unique URL blocking score of 89% and over-time protection rating of 92%. Enabling Application Reputation on 上, ページのトップへ of SmartScreen increased the unique URL block rate of Internet Explorer 9 によって 11% (to 100%) at zero 時 as well as the over-time protection によって 8% (to 100%),” NSS Labs revealed.

“Internet Explorer 9 was によって far the best at protecting against socially-engineered malware, even before App Rep’s protection is layered on 上, ページのトップへ of SmartScreen.”

Socially engineered malware refers to malicious code that is being spread through social engineering techniques to unsuspecting users.

Victims are in fact tricked through various means into compromising their own machines によって installing malware which often masquerades as legitimate software, from antivirus to codecs.

Socially engineered malware doesn’t use vulnerabilities in the software to spread, and as such, traditional security layers, sandboxing for example, are ineffective when it comes to blocking infections.

Instead, such malicious code is deployed によって the users themselves, after they’re tricked によって attackers to believe that they’re actually installing legitimate software.

Here are NSS Labs’ conclusions for the additional browser tested:



“Firefox 4 achieved a 13% protection rating, on par with protection offered によって Chrome and Safari —86% less protection than Internet Explorer 9 and 77% less than Internet Explorer 8. Firefox exhibited deterioration in protection compared with our Q3 2010 global test that can be attributed to either the implementation of 安全, 安全です Browsing API v2 または new tactics being used によって cybercriminals that 安全, 安全です Browsing has not yet adapted to. There was a slight 1% improvement between zero-hour protection (16%) and eventual protection at the 19 日 mark (17%).

Safari 5 achieved a 13% protection rating on par with Firefox and Chrome converging at a roughly 17% block rate after 19 days. However, Safari presented a notable lag in protection vs. Firefox with zero-hour protection of 11% (vs. Firefox’s 16%).

With a protection rating of 13%, Chrome 10 offered nearly identical protection to Safari and Firefox. Browser Security Comparative Test: Socially-Engineered Malware

Opera 10’s 全体, 全体的です blocking rate of 5% was consistently the lowest in the group. However, this was an improvement over the 0% scores in our 前 global tests, and is likely attributable to the company’s partnership with antivirus firm AVG.”

In the past, in response to earlier NSS Labs reports also focused on socially engineered malware, browser vendors such as Google and Opera criticized the results, and raised 質問 about their accuracy.
