Demystifying the Dark Web: Measuring and analyzing online anonymous marketplaces

15.06.2018

Talk by Nicolas Christin, Carnegie Mellon University


Developments in anonymous communication technologies in the 1990s and early 2000s led to the rise of a number of websites and services, that users could participate in anonymously. Collectively referred as the "dark web," these sites and services are surrounded by a mystique that is actually rather unwarranted, given that, however anonymous they may be, they are publicly accessible.

In this talk, Nicolas Christin will focus on "dark web markets" or online anonymous electronic marketplaces, in which buyers and sellers can transact with anonymity guarantees far superior to those available in online or offline alternatives. Unsurprisingly, the superior anonymity guarantees result in a number of illicit products (narcotics, compromised digital goods) being bartered.

Nicolas Christin will describe longitudinal measurements that help us better understand this dynamic ecosystem and its evolution over a number of years. In the process, I will highlight the scientific challenges in collecting such data at scale. He will show that, despite the primarily illicit nature of the offerings on these markets, online anonymous markets share a number of commonalities with their more legitimate cousins, thereby evidencing that a number of economic properties generally apply to online commerce, irrespective of the legality of its purpose.
