The Internet's Bad Neighborhoods

An anonymous reader writes "Of the 42,000 Internet Service Providers (ISPs) surveyed, just 20 were found to be responsible for nearly half of all the spamming IP addresses — and some ISPs have more than 60% of compromised hosts, mostly in Asia. Phishing Bad Neighborhoods, on the other hand, are mostly in the U.S. Also, there is a silent ticking 'spam' bomb in BRIC countries: if India would have the same Internet penetration rate as the United States while keeping its current ratio of malicious IP addresses, we would observe 200% more spamming IP addresses worldwide. These are just few of the striking results of an extensive study from the University of Twente, in The Netherlands, which scrutinizes the Internet Bad Neighborhoods to develop next-generation algorithms and solutions to better secure networks."

Break it down per capita

[roman_mir]

Brazil: 196,655,014 people (World Bank)
Russia: 141,930,000 people
India: 1,241,491,960 people
China: 1,344,130,000 people

that's 2,924,206,974 people total.
world population: 6,973,738,433 people, so BRIC countries are 41% of the total in population.

FTFA:

Of the 42,000 Internet Service Providers (ISPs) surveyed, just 20 were found to be responsible for nearly half of all the internet addresses that send spam.

so I take it "nearly half" is between 40% and 50%, but less than 50%. If it's over 41%, then what we are looking here is some form of distribution of 'nuisance' that is related to the actual population and it probably shows normal distribution.

Is this really a surprise?
