Here they are: the latest "Dirty Dozen" SPAM­PION­SHIP tables, detailing the globe's most dastardly distributors of delinquent data during the first quarter of 2015.

If you haven't seen the Dirty Dozen before, here's how it works.

SophosLabs maintains a large network of spamtraps, operated around the world with the express purpose of collecting spam.

And, boy, do they collect spam!

Of course, whenever spam falls into a trap, we can tell where the final step of its journey started by looking at the IP address of the computer from which the offending email was sent.

It's possible to track back individual IP numbers fairly accurately, sometimes down to a street block, often to a suburb or metro area, and almost always to the sender's country.

In other words, our spamtraps tell us which countries are the worst senders of spam.
