According to a study by Kaspersky Labs, the US – once the leading source of spam messages – doesn’t even appear in the list of top 10 spam sources. Not only that, but it barely makes the top 20 on occasion.
Why the big change in spam sources?
It seems that botnets Pushdo/Cutwail, Bredolab and Rustock all played a very large role in keeping the US at the top of the list for spam distribution. Once those botnets started to be taken offline, the US started to trickle down the spam source ranks.
The top spam producing countries are now India, Indonesia, Brazil, and Peru. Together they contribute to nearly half of the world’s spam.
Kaspersky Labs' analysis even suggest that cybercriminals have learned from the anti-botnet crusades that lead to the take-down of the top US botnets and they’re spreading their resources across different countries to ensure they’re able to thrive should they lose a bot somewhere.
