Sophos research launched on Monday has revealed that while spam levels in the UK have dropped by nearly 50 per cent, they have skyrocketed in India, with the country now responsible for a tenth of the world's spam messages.
The marked growth in Indian spam levels was revealed by Sophos in its annual Dirty Dozen report.
Sophos analysts reported that Indian networks relayed 9.3 per cent of all the spam email messages sent this quarter.
Second in the table of offenders is the US. Last year's biggest contributor, the US is now listed as being responsible for 8.3 per cent of all spam messages.
The rise in spam in India runs contrary to a global decrease in overall spam levels. Demonstrated by the UK, which saw a 50 per cent decrease from its 2011 3.2 per cent share, Sophos suggested the decrease was due to improved security measures within Europe.
In line with this, poor internet security on Indian networks and computers was cited as a key reason for the marked increase in Indian spam.
"My assumption would be that Indian computers are less likely to be running up-to-date security than those, say, in the UK and USA," said Sophos analyst Graham Cluley.
Speaking to V3, Cluley went on to suggest that while spam levels have decreased, the nature of the messages has taken a darker tone, with many being part of phishing scams run by cyber criminals.
"Worldwide, the trend is for more malicious spam and we'd expect that from India too," he said.
The news follows on from previous research by IBM warning that cyber criminals are finding new ways to circumvent companies' online security.
