Dark Web Expert Explains How He Infiltrates Cybercrime Forums
A deep dive into HUMINT tradecraft on cybercrime forums — and the open-source tooling behind it.
PROJECTS
(Open-source tools)Robin
An AI-powered tool for dark web OSINT investigations — using LLMs to refine queries, filter results from dark web search engines, and produce an investigation summary.
EXPERIENCE
Leading research and intelligence efforts across cybercrime and dark-web threats — from investigation through automation to decision-ready reporting.
Detecting and disrupting scraping operations at scale — analyzing large datasets, building automation, and running OSINT-driven investigations to drive high-impact enforcement against automated abuse.
Delivered tactical and operational intelligence on client RFIs, served as SME for Generative-AI threat-intel projects, and curated OSINT/SOCMINT/HUMINT investigations into actionable, IOC- and TTP-enriched deliverables.
Ran surface and dark web investigations, profiled threat actors and ransomware groups, and built Python automation that cut data-collection time by 40%.
Deep-dived malicious data from dark web forums and markets, applied NLP (LDA, CatE) to large unstructured datasets, and generated six threat-intelligence metrics.
Performed OSINT and HUMINT across 20+ dark web forums and markets, and designed an automated Scrapy-based scraping tool feeding Elasticsearch.
