Abstract

Over the past two decades, the Internet has become an essential tool in the lives of millions of people. Unfortunately, this success has also attracted cybercriminals who exploit the Internet as a platform for illicit gain. Perhaps the most familiar scam is sending unsolicited advertisements (spam), clogging inboxes and putting people's computers at risk of dangerous malware infections. Understanding the mechanisms and effectiveness of these scams is essential to building effective countermeasures to cybercrime. In this talk, I'll explain the modern spamming landscape and present research that help us better understand how spammers make their money online. One effort uses the technique of botnet infiltration to examine a spam campaign from the point of view of the spammers. Botnet infiltration allows us to measure their operation including the advertisements' effectiveness and the worldwide use of spam filtering techniques. The second effort exploits key information leaks to answer key questions about the modern affiliate marketing-based spam ecosystem, from estimating their worldwide gross revenue, to understanding customer demographics and their most popular products.
