US leads the dirty dozen spammers
Published: 24 Dec 2004 11:45 GMT
The United States is in a league of its own when it comes to sending junk mail to email users.
Researchers at security company Sophos found after scanning its global network of honeypots -- computers designed to attract spam emails and viruses -- that 42 percent of all spam sent this year came from the United States.
Sophos says this is evidence that America's anti-spam legislation simply isn't working.
"When we released the first report back in February, the US had the excuse that the Can-Spam Act had been in existence for only three months," said Graham Cluley, senior technology consultant for Sophos, on Friday.
"Almost a year and millions of spam messages later, it is quite evident that that the Can-Spam legislation has made very little headway in damming the flood of spam."
South Korea and China came in second and third place, respectively, but together they sent just half as much spam as the US.
The United Kingdom came ninth in the list, and was responsible for just 1.13 percent of the world's spam.
The results came in as follows:
United States: 42.11 percent
South Korea: 13.43 percent
China (including Hong Kong): 8.44 percent
Canada: 5.71 percent
Brazil: 3.34 percent
Japan: 2.57 percent
France: 1.37 percent
Spain: 1.18 percent
United Kingdom: 1.13 percent
Germany: 1.03 percent
Taiwan: 1.0 percent
Mexico: 0.89 percent
Sophos warned that many spammers are using hacked PCs with broadband connections to send out their spam. This could explain South Korea's position near the top of the list, as it leads the world for broadband penetration.
"Spammers are motivated by one thing -- quick, easy money," added Cluley. "There are plenty of spammers who have taken their money-making schemes to the extreme by hacking into innocent third-party computers in an effort to do their dirty work."
"Many of the computers sending out spam are most likely to have had their broadband internet connections exploited by remote hackers. Zombie computers -- PCs that have been compromised by hackers or virus writers -- are sending out over 40 percent of the world's spam, and many users who fall victim are unaware."
