Spam originating from hacked computers in China has "steadily" dropped, and the country is now off the Top 12 chart for spam relaying.

In a report covering the first quarter, security firm Sophos said China had dropped off "Dirty Dozen" list to No. 15. China contributed to just 1.9 percent of the world's spam during the quarter--done primarily through malware-infected computers called bots or zombies.

China had earned a bad reputation as the "launch pad of targeted attacks against foreign companies and government networks," the report said. However, "at least in the last 12 months," the proportion of spam relayed by computers in the country has steadily reduced.

The revised "Dirty Dozen" list: U.S., India, Brazil, South Korea, Vietnam, Germany, U.K., Russia, Italy, France, Romania, and Poland.
