I've run Google Safe Browsing against the top 1 million (based on number of visits) websites according to Alexa. 621 of them are blacklisted by Google Safe Browsing. I've looked at the most popular to understand why they are considered malicious. Here is what I found for the most popular blacklisted sites:
|18,784||financereports.co||Scam||Work from home scam|
I have also checked to see which country the blacklisted domain is hosted in. Here is the breakdown:
Most of the blacklisted sites are hosted in the US. Western Europe (especially Germany, France and the Netherlands) is number two, followed by China (8%).
No site is safe from hijacking. Personal websites and top-10,000 sites are all likely to be infected at some point.
