New spam sources in the making

After the Pushdo/Cutwail, Bredolab and Rustock botnets were taken offline, the geography of spam sources underwent some major changes. In particular, from September 2010 the US, for a long time the leading spam distributor, began to lose ground. For several months now it hasn’t even made it into the Top 10 leading sources of spam and only occasionally appears at the bottom of the Top 20.

The US and some European countries have been replaced by Asian and Latin American countries. The cybercriminals have clearly established new bases for distributing spam with eight of July’s top 10 spam sources located in Asia and Latin America.
