article imageMost spam comes from just 20 ISPs

By Tim Sandle     Mar 16, 2013 in Technology
A new study has shown that over 50% of all junk mail and spam on the Internet is generated from just 20 Internet service providers (ISPs) out of 42,000 ISPs currently registered worldwide.
The study, which can be downloaded to read in its entirety, looked at the sources of spam and junk mail. The research has been carried out by analysis Giovane Cesar Moreira Moura of the University of Twente. Moura has found that some networks could be classed as "bad neighborhoods" because they are the places where malicious activity was more likely.
In all Moura examined 42,201 ISPs. According to his university's research brief, he has found that about 50% of all junk mail, phishing attacks and other malicious messages come from just 20 networks. Many of these networks are concentrated in India, Vietnam and Brazil. However, the Internet's most crime-ridden network is Spectranet in Nigeria, where 62% of all the addresses controlled by that ISP were seen to be sending out spam.
Moura's study was carried out to help fine-tune computer security tools that scrutinize the net addresses of email and other messages to help them work out if they are junk or legitimate, according to Web India.
Following this objective, Moura is quoted by the BBC as saying: "If security engineers want to reduce the incidence of attacks on the internet, they should start by tackling networks where attacks are more frequently originated."
Hopefully this new research will lead to enhanced Internet security.
