Sophos reveals latest 'Dirty Dozen' spamming countries
Sophos published its latest report on the top 12 spamming countries during the last six months.
Experts at SophosLabs analyzed all spam messages received in its global network of spam traps to identify the top 12 countries of origin for spam. The United States remains the worst offender, but is relaying significantly less of the world's spam than it did a year ago, while spam traffic from China and South Korea increased substantially.
Meanwhile, Sophos found that more than 60% of spam is now generated from zombie computers. The evolving nature of spamming now allows culprits to be in a different country than the innocent computers they exploit.
