Dubai: More than 50 percent of all spam messages in the world during the third quarter of 2011 originated from just six countries, with India accounting for the highest 14.8 percent of such messages.

According to Kaspersky Lab's spam report, India was ahead of countries like Indonesia (10.6 percent), Brazil (9.65 percent), Peru (6.65 percent), South Korea (5.85 percent) and Ukraine (3.7 percent).

All of the countries that make up the top 10 sources of spam are situated in South America, Asia and Eastern Europe, the report said.

"This is due to the fact that there are numerous users in these countries and they are, for the most part, not very experienced when it comes to IT security. This makes them a soft target for cybercriminals spreading spam-bots," it said.

The report said that all GCC countries together accounted for only 1.33 percent of all global spam, with Saudi Arabia leading the pack. This was attributed to the low number of users and more vigilance in protecting computers in these countries.

GCC countries are Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and United Arab Emirates.
