Exploring the Darknet: Between Safe Haven, Crime, and Conspiracy Theories

In this episode of CAISzeit, host Dr. Matthias Begenat speaks with Dr. Marco Wähner, postdoctoral researcher at CAIS, about the fascination, functions, and misconceptions surrounding the Darknet. Together, they take a scientifically grounded look at the hidden layers of the internet and explore the Darknet’s role in protecting freedom of speech, as well as its use in spreading conspiracy theories.

To many, the Darknet is a mysterious space brimming with illegal activity. But what is really behind it? And how does it differ from the surface web? In this episode of CAISzeit, we debunk common myths and speak with Dr. Marco Wähner, interim head of the “Research, Data & Methods” team at CAIS, about the technical foundations, political potential, and societal challenges of the Darknet.

How does the Tor network work? What are Hidden Wikis, and how does one even navigate the Dark Web? We discuss how the Darknet can serve as a safe haven for journalists and whistleblowers under authoritarian regimes – and what kinds of platforms exist beyond the clichés, including offerings by the BBC and Deutsche Welle.

Dr. Marco Wähner also shares insights into his research in cooperation with Felix Soldner from GESIS – Leibniz Institute for the Social Sciences: How can the Darknet be studied scientifically? What data is available – and what isn’t? What makes research in this area particularly challenging? And how do conspiracy theories become an argument for selling certain products?
