Relationship Amongst Spam Actors Researched

Anonymous Coward writes | about a month and a half ago

An anonymous reader writes "A team of researchers at the UC Santa Barbara and RWTH Aachen presented new findings on the relationship of spam actors at the ACM Symposium on Information, Computer and Communications Security. This presents the first end-to-end analysis of the spam delivery ecosystem including: harvesters crawl the web and compile email lists, botmasters infect and operate botnets, and spammers rent botnets and buy email lists to run spam campaigns. Their results suggest that spammers develop a type of "customer loyalty"; spammers likely purchase preferred resources from actors that have "proven" themselves in the past. Previous work examined the market economy of the email address market in preparatory work: 1 million email addresses were offered on the examined forum for anywhere ranging between 20 and 40 Euros."
