Robin: The Archaeologist of the Dark Web - Because Manual Dark Web OSINT is So Last Season
Recon Village @ DEF CON 33 • 8th, 9th and 10th August 2025
Abstract
When exploring the Dark Web for OSINT or CTI investigations, you may be overwhelmed with numerous onion links, questionable marketplaces, and numerous search engines. With time constraints, how do you make sense of all this information and prioritize what truly matters?
Enter Robin, an AI-powered Dark Web OSINT tool to streamline your investigations. Robin takes your query, automatically searches across multiple Dark Web search engines, scrapes relevant onion sites, and uses AI to generate clear, actionable investigative summaries. No more juggling five different tools or wasting hours validating dead links. In this talk, I'll walk you through the real pain points of today's Dark Web OSINT tools and show how Robin was built to solve them. I'll cover the architecture, the scraping and summarization pipeline, and how Robin fits into real-world investigation workflows.
By the end of this talk, you will have a fresh perspective on Dark Web OSINT, a practical tool to use right away, and insights into how AI can simplify the investigative process.
