Sophos Labs experts have released their latest "dirty dozen" report detailing the world's top spam-relaying countries - and have discovered that India has solidified its position as the biggest global contributor to the junk email problem.
Despite only 5.3% of the world's internet users reportedly living in India, the country topped the list by a significant margin and was accountable for 11.4% of the world's spam seen throughout April, May and June.
The vast majority of spam comes from home computers that have been compromised by hackers in this way. Remote hackers can send spam from recruited computers, as well as potentially steal information or install other malicious code.
The latest "Dirty Dozen" stats suggest that as more first-time internet users get online in growing economies they are not taking appropriate measures to block the malware infections that turn their PCs into spam-spewing zombies.
