A new mail spam report from Commtouch says China is a top location for zombie IP addresses.The “2008 Email Threats Trend Report” is based on the automated analysis of billions of email messages and covers the third quarter of 2008. Spam levels throughout the third quarter averaged 77% around the world, as in the previous quarter, ranging from a low of 61% to a peak of 94% of all email. Legitimate sites and senders were used by spammers to cloak their illicit activity, and over half of zombies and bots change their IP address daily.
