A study called "Mapping the Mal Web" has been written by McAfee SiteAdvisor. It is based on analysis data from massive tests of website exploits, downloads, the "spamminess" of the sites et cetera ( I reckon they use automatic tests of some kind for this ).

It is an interesting read, but most of it was expected, e.g. the most risky sites are the ones in eastern Europe, Russia and China. What surprised me a bit was the result of the .info sites.

A stunning 73.2% of the more than 6,000 .info sites that we have tested for e-mail practices are rated risky, meaning that SiteAdvisor registrations at these sites resulted in the receipt of high volume e-mail, spammy e-mail or both.
