Australia and New Zealand are relatively clean when compared with the 12 top spam-relaying countries for the third quarter of 2007, according to research put together by IT security company, Sophos.
The United States was responsible for the more spam than any other country (28.4 per cent) with South Korea (5.2 per cent) and China/Hong Kong (4.9 per cent) following, according to the results which were collated from spam messages caught in the company’s own ‘spam traps’.
“Yet again the US relayed more spam than any other nation, accounting for a massive 28.4 percent – meaning that almost one in three of all the world’s spam emails is being sent through a compromised US computer,” said Sophos.
Australia and New Zealand sit in 37th (0.4 per cent) and 79th (0.1 per cent) place respectively, contributing to less than one per cent of the world’s spam.
“It seems as though a major American spammer is arrested every other week at the moment, but despite these high-profile lawbreakers being put away, the US continues to relay far more spam than any other nation on the planet,” said Sophos senior security consultant, Carole Theriault.
“This level of activity can’t be attributed solely to the slick operations of a few cash-hungry criminals. The problem is there are thousands of spammers using many thousands of compromised zombie computers in the US.
“The only way we’re going to reduce the problem is if US authorities invest a lot more in educating computer users of the dangers, while ensuring ISPs step up their monitoring efforts to identify these compromised machines as early as possible.”
The top twelve spam-relaying countries are:
1 United States 28.4%
2 South Korea 5.2%
3 China (inc.Hong Kong) 4.9%
4 Russia 4.4%
5 Brazil 3.7%
6 France 3.6%
7 Germany 3.4%
8 Turkey 3.2%
9 Poland 2.7%
10 United Kingdom 2.4%
11 Romania 2.3%
12 Mexico 1.9%
Others 33.9%
During August 2007 Sophos identified a series of large-scale malware attacks made via spam email, with weblinks inserted into spam messages that directed recipients to malicious websites designed to infect their PCs.
