India, Bank of America, and CyberSURF: December 2011 SpamRankings.net

In SpamRankings.net for December 2011, worldwide India spammed the most, while Bank of America topped one U.S. ranking, and CyberSURF peaked in Canada, but Cleveland Clinic cleaned up its act.

More on those and other interesting rankings in later posts.

What is IPWORLDNET and why is it spamming from Canada?

In the October SpamRankings.net for Canada (from CBL data), IPWORLDNET is that big blue molar tooth in the graph on the right. In the interactive chart you can see IPWORLDNET’s Autonomous System (AS) 19875 winning the month with two bursts of spam, and then dropping almost to zero.

That’s not the only spamming churn activity in Canada for October. The log chart shows MetroBridge Networks Corporation AS 25976 METROBRIDGE-NET jumping up from zero to take ninth place. It looks like one organization may have cleaned up its act while another got infested.

Last month’s winner, Canaca-com’s AS 33139 CANACA-210, came in second. From there down it’s mostly the usual suspects in slightly different orders. Interestingly, longterm winner Bell Canada’s AS 577 BACOM only came in fourth. This is unusual for a national telco. Maybe they’re watching the rankings?

Upset in Canadian spam rankings: Canaca took first, Bell Canada down to fifth!

Canaca-com’s AS 33139 CANACA-210 rose from sixth place in August to first in September in SpamRankings.net for Canada from CBL data. Long-time winner Bell Canada’s AS 577 BACOM fell from first to fifth.

Two ASNs had big spurts of spam in September. iWeb’s AS 32613 got to second place in the last two weeks of the month. Like in August, IPWorld’s AS 19875 did one big spam spew, but this time it almost doubled its closest competitor, breaking 100,000 messages!

What is making Canada suddenly attractive to spammers?
