US takes title as top spam-relaying nation in Q2
Sophos has published a report on the top twelve spam-relaying countries over the second quarter of 2006.
Experts at SophosLabs scanned all spam messages received in the company's global network of spam traps, and have revealed that for the first time in more than two years the U.S. has failed to make inroads into its spam-relaying problem. The U.S. remains stuck at the top of the chart and is the source of 23.2 percent of the world's spam. Its closest rivals are China and South Korea, although both of these nations have managed to reduce their statistics since Q1 2006.
The vast majority of this spam is relayed by 'zombies,' also known as botnet computers, hijacked by Trojan horses, worms and viruses under the control of hackers.
