Two separate tests performed by NSS Labs measured protection against phishing and socially engineered malware across 5 browsers: Apple Safari 4, Google Chrome 2, Mozilla Firefox 3, Opera 10 Beta and Windows Internet Explorer 8.
One of the key things to note is that while the other browsers maintained or decreased protection between the two tests, Internet Explorer continued to improve its protection against cybercriminals.
“Socially engineered malware is the most common and impactful threat on the Internet today, with browser protection averaging between 1% and 81%. Internet Explorer 8 caught 81% of the socially engineered malware sites over time, leading other browsers by a 54% margin. Safari 4 and Firefox 3 caught 21% and 27% respectively, while Chrome 2 blocked 7% and Opera 10 Beta blocked 1%.
Phishing protection over time varied greatly between 2% and 83% among the browsers. Statistically, Internet Explorer 8 at 83% and Firefox 3 at 80% had a two-way tie for first, given the margin of error of 3.6%. Opera 10 Beta, exhibited more extreme variances during testing and averaged 54% protection. Chrome 2 consistently blocked 26% of phishing sites, and Safari 4 offered just 2% overall protection. Firefox 3.5 crashing issues prevented it from being tested reliably.”
