Dirty Dozen Spamming Countries
Lynnfield, MA -- Sophos, a developer of integrated threat management software, published its latest report on the top 12 spamming countries during the last six months.
Researchers at SophosLabs analyzed all spam messages received in its global network of spam traps to identify the top 12 countries of origin for spam. Sophos found that more than 60% of spam is now generated from zombie computers -- hijacked PCs infected by malware. The evolving nature of spamming now allows culprits to be in a different country than the innocent computers they exploit.
The "Dirty Dozen" countries are as follows (figures in brackets denote percentages for the same period in 2004):
April - September, 2005
1. United States 26.35% (41.50%)
2. South Korea 19.73% (11.63%)
3. China (incl. Hong Kong) 15.70% (8.90%)
4. France 3.46% (1.27%)
5. Brazil 2.67% (3.91%)
6. Canada 2.53% (7.06%)
7. Taiwan 2.22% (0.86%)
8. Spain 2.21% (1.04%)
