India number two in relaying spam, says Sophos

InformationWeek News Network, October 14, 2010

One in 20 spam messages sent from India

IT security and control firm Sophos has published the latest report into the 'Dirty Dozen' spam-relaying countries, covering the third quarter of 2010.

The top five spam relaying countries for July to September 2010 are as follows:

 

 Country   Contribution to global spam (in percentage)
 United States                             18.6
 India                                7.6
 Brazil                                 5.7
 France                                5.4
 UK                                5.0


Almost all of this spam comes from malware-infected computers (known as bots or zombies) that are being controlled by 'botherder' cybercriminals.  One of the primary tactics used by cybercriminals to grow botnets involves tricking computer users into clicking malicious links - either contained in spam email or social networking messages - which direct computers to malware infected webpages

"Spam isn't just a nuisance, it's used by cybercriminals as a means of growing their operations," said Graham Cluley, Senior Technology Consultant at Sophos.  "You should never even be tempted to open a spam message out of curiosity, as it can only take a second to effectively hand over control of your computer to the spammers.  If your computer does become part of a botnet, you're also inviting further malware infections, which may compromise your personal or banking details."
