Snowshoe spamming begins to look like a rising tide.
Peaking at the end of March 2012, the Ogee snowshoe spam winner is AS 16226 GNAXNET-AS - Global Net Access LLC. GNAXNet actually placed another Autonomous System in the same time frame, AS 3595.
U.S. Brinkster's AS 33055 BCC-65-182-96-0-PHX finally cleaned up its act and went to zero Ogee volume 11 April 2012. Canada's AS 32613 IWeb also went to zero on 23 March 2012.
On the other hand, it looks like a new surge of snowshoe spam is starting mid-April, including some organizations maybe not usually considered hosting companies, such as Cogent's AS 174.
Meanwhile, Belarus' AS 6697 BELPAK-AS already went from #7 to #5 worldwide in March, pushing Belarus up from #16 to #12 among countries.
And NOC's AS 21788 keeps on rolling waves of snowshoe spam.
All these volume numbers and rankings are provisional, especially considering we're seeing so many ASes and netblocks that were previously not spamming that we're tuning our database to be sure we're properly accounting for them all.
Nonetheless, it looks like snowshoe may be a rising spamming strategy.
