Top 10 Countries with most malicious networks

In the past we have released many top 10 lists showing countries in the order of spam production or other similar criteria. One of the latest lists orders the results like this:

  1. United States
  2. China
  3. Russia
  4. United Kingdom
  5. Germany
  6. Japan
  7. Brazil
  8. Romania
  9. Ukraine
  10. Turkey

While the order is technically accurate when considering the volume of spam or the number of networks involved, we decided to examine the number of malicious networks involved as a percentage of the total number of networks in a given country. The results. showing the percentage of networks containing malicious activity, including spammers, hackers, comment spammers or other detrimental outgoing traffic, are astonishing.

Here are the results based on percentage of infected networks:

  1. Brazil 89%
  2. Turkey 54%
  3. Romania 39%
  4. China 32%
  5. Russia 11%
  6. United Kingdom 11%
  7. Japan 10%
  8. Ukraine 9%
  9. Germany 6%
  10. United States 6%

Keep in mind, these results show only countries that are listed as the current top 10 global spammers. A full review of all countries might lead to an even more dramatic result. Is it 15 times more likely an email from a network in Brazil will contain spam or other malicious content than from a network in Germany or the United States? Maybe, but maybe not.

We will continue to study the issue and release our findings in the near future.
