Using data from Google’s Safe Browsing initiative, StopBadware.org analyzed over 200,000 websites found to engage in badware behavior. The analysis found that over half of the sites were based on Chinese network blocks, with a small number of blocks accounting for most of the infected sites in that country. The U.S. accounted for 21% of infected sites, and these were spread across a wide range of networks.
Compared to May 2007, the total number of sites was much higher, likely due both to increased scanning efforts by Google and to increased use of websites as a vector of malware infection. Several U.S.-based network blocks that were heavily infected last year, including that of web hosting company iPowerWeb, whose network block topped last year’s list, no longer host large numbers of infected sites.
