Understanding the Growth of the Underground Economy
Abstract: New threats are inevitably driven by changes in opportunity. Nowhere is this more true than on the Internet, where the combination of widespread software homogeneity and unrestricted high-speed connectivity have created "perfect storm" conditions for large-scale outbreaks of network-borne infections. Indeed, over the last decade, the ability to easily compromise large numbers of Internet hosts has emerged as the backbone of a vibrant criminal economy encompassing unsolicited bulk-email (SPAM), denial-of-service extortion, piracy, phishing and identity theft. Using tools such as worms, viruses, and web-based exploits, the technical cadre of this community can leverage a small investment in software into a large-scale virtual commodity - hundreds of thousands of remotely controlled "bot" hosts - that are then used, resold and leased to others. This capability effectively provides a platform upon which higher-level criminal
applications are deployed (such as SPAM forwarding, DDoS, piracy, etc.) In this talk I will describe the growth of this ecosystem, its underlying technical drivers and provide preliminary data quantifying the emergence of a vibrant third-party market economy in support of on-line crime.
