Panda Security has released a report stating that Brazil, India, Korea, Vietnam and U.S. head the list of countries from which most spam was sent during the first two months of the year 2010. With respect to the cities from which spam was being sent, Seoul was first in the list, followed by Hanoi, New Delhi, Bogota, Sao Paulo and Mumbai.
The five million emails analyzed by PandaLabs came from a total of almost one million different IP addresses. This shows that the spam is mostly sent from zombie computers belonging to a botnet. This way, the computers of the infected users themselves are those which send the spam. The cybercrooks have thousands of computers at their disposal, which do the dirty work for them.
