Abstract

“ A Wikileaks-style war of attrition between two competing rogue Internet pharmacy gangs has exposed some of the biggest spammers on the planet. The latest casualties? Several individuals likely responsible for running Grum, currently the world’s most active spam botnet.

In the summer of 2010, hackers stole and leaked the database for SpamIt and Glavmed, sister programs that paid people to promote fly-by-night online pharmacies. According to that data, the second-most successful affiliate in SpamIt was a member nicknamed “GeRa.” Over a 3-year period, GeRa’s advertisements and those of his referrals resulted in at least 80,000 sales of knockoff pharmaceuticals, brought SpamIt revenues of in excess of $6 million, and earned him and his pals more than $2.7 million.
