Far east starts to dominate in source of IT security threats

Network Box : 02 December, 2009  (Technical Article)
With Vietnam hitting the top of the spam source table and significant threats from Korea and Malaysia, the far East is beginning to eclipse other regions in IT malware origination
Vietnam is now responsible for more than 10 per cent of the worlds spam, according to threat analysis from managed security firm, Network Box. November saw malware threat levels remain consistently high with Vietnam taking the number one spam spot from last month's chart topper, Brazil.

Spam - The level of spam originating from Vietnam has increased by 3.4 per cent: it now accounts for 10.9 per cent of worldwide spam production, beating Brazil into second place (Brazil's spam production levels have dropped to 8.3 per cent since October). Korea still occupies the third position in the charts, seeing an increase in spam production of 1.5 per cent, to 7.07 per cent.

Phishing - Network Box's analysis of internet threats in November 2009 show a rise of three per cent in phishing attacks globally, reaching 28.3 per cent - although levels are still not near their September peak of 33.3 per cent.

Viruses - Once again, Brazil, the US and Korea are dominating the virus charts as the top three sources of viruses, with Brazil's levels static at 14 per cent. The US has seen a rise of 2.4 per cent in virus production since October and Korea a rise of 1.7 per cent.

India continues to be a significant source of viruses, with 4.16 per cent originating from the sub-continent. The UK has entered the virus charts, contributing 2.7 per cent of global virus production.

Simon Heron, Internet Security Analyst for Network Box says: "Last month we noticed that fewer malware attacks were originating from the traditional top sources, such as the US and China. We can see the effect of the dispersal of malware production in the rise of Vietnam to the number one source of spam. The speed at which spam production centres are created, used and closed down again is fast and difficult to contain."
