Trailrunner7 writes "China has become the go-to bogeyman behind every cyber attack or malware campaign, but if you're looking for the most malicious hosting providers on the Web, you won't find any of the top 10 in China. In fact, the United States and Russia have many more bad hosting providers in the top 20 than China does. ... [One] interesting data point is the appearance of Amazon in the top 10 list of providers hosting the highest concentration of infected Web sites. These are the kind of sites used in drive-by download attacks and to deliver exploits from exploit packs. Amazon, with more than two million IPs, ranks fourth in the list of providers hosting infected sites. Also on that list is Google, which comes in at number seven. The top spot belongs to Mail.ru, a Russian hosting provider."
