On the Spam Campaign Trail

Category: Software and Web Development, Security

Overview Over the last decade, unsolicited bulk email, or spam, has transitioned from a minor nuisance to a major scourge, adversely affecting virtually every Internet user. Industry estimates suggest that the total daily volume of spam now exceeds 120 billion messages per day; even if the actual figure is 10 times smaller, this means thousands of unwanted messages annually for every Internet user on the planet. This paper explores a new methodology-distribution infiltration-for measuring spam campaigns from the inside. This approach is motivated by the observation that as spammers have migrated from open relays and open proxies to more complex malware-based "Botnet" email distribution, they have unavoidably opened their infrastructure to outside observation.
