According to a recent analysis conducted by NSS Labs, Internet Explorer 9 tops the chart when compared to other browsers such as Chrome, Firefox, and Safari, when it comes to blocking social engineering attacks. In a report last year, NSS Labs research shows that IE9 is able to either block or warn against 99% of socially-engineered malware.
Internet Explorer 9 caught an exceptional 92% of the live threats with SmartScreen URL reputation, and an additional 8% with Application Reputation. IE9 with SmartScreen offers the best protection of any browser against socially engineered malware.
Internet Explorer 8 caught 90% of the live threats, an exceptional score that also matched NSSLab’s broader findings from the Q3 2010 global test.
Apple Safari 5 caught 13% of the live threats. Protection offered was near identical to that of Chrome and Firefox.
Mozilla Firefox 4 caught 13% of the live threats, far fewer than Internet Explorer 8 or Internet Explorer 9. Results were 6% less than the 19% protection rate observed in NSSLab’s Q3 2010 global test, indicating either an overall drop in protection for Firefox or regional weakness in Europe.
Google Chrome 10 caught 13% of the live threats, considerably more than the 3% observed during the Q3 2010 global test and a welcome improvement.
Opera 11 caught 5% of the live threats, providing a measurable amount protection against socially-engineered malware for the first time.
NSS Labs reported;
Socially Engineered Malware remains the most common security threat facing Internet users today and European users have found themselves particular targets of malware authors over the last 12 months. According to the EU’s statistics office, Eurostat, almost one third of internet users in the European Union were victims of malware infections in 2010 despite the majority having security software installed.
