USA is the best country in the WORLD... for sending spam

Floats to top of Dirty Dozen - the junkmail conduit sh*t list

The US has reclaimed its position as the world's leading spam-relaying country, but you'd be wasting your time looking for junkmail crimelords...

In the last three months, almost one-fifth (18.3 per cent) of all global spam has been pushed through computers in the US, according to figures from anti-virus firm Sophos.

However, the list illustrates the location of abused computers (almost always Trojan-infected zombie drones) pwned by spammers rather than the location of current spam kingpins. The latest figures suggest that the hackers who harvested compromised computers for spammers are reaping a bumper harvest in the Land of the Free, suggesting that the security of American computers needs to be improved.

In the latter half of 2012, India had been leading the way as a conduit for junk mail but it recently fell back to third place, relaying an estimated 4.2 per cent of spam between December 2012 and February 2013.

The Dirty Dozen, in order, are:

China leapfrogged the likes of Russia and South Korea to rise to second place in the chart (8.2 per cent of spam), after a spell in the lower half of the Sophos's "Dirty Dozen" of top spam relayers. ®
