Advanced OSINT Techniques: Expert Strategies, Automation Workflows, and Case Studies for Digital Intelligence Professionals
This book is the second volume in the OSINT series. The first book, OSINT for Beginners, introduced readers to the fundamentals of open-source intelligence. This volume, Advanced OSINT Techniques, takes the next step by delivering professional-grade methods, automation workflows, and case studies designed for digital intelligence practitioners who need depth, speed, and precision.
You will learn how to go far beyond basic search. Each chapter focuses on the techniques and tools professionals use in real investigations:
Advanced search and data collection across the surface web, deep web, and dark web.
Specialized search engines and custom queries that filter noise and reveal hidden datasets.
Infrastructure investigations covering DNS, IPs, ASNs, and TLS certificate correlation.
Automated social media monitoring, scraping, and network mapping at scale.
Multimedia forensics, including metadata extraction, hashing, and deepfake detection.
Breach data and dark web analysis with an emphasis on ethical and legal boundaries.
Scripting and APIs to build automated OSINT pipelines and visualization dashboards.
Case studies and capstone projects replicating corporate, law enforcement, and journalism investigations.
Each chapter includes structured labs, exercises, and case simulations. These are not theoretical discussions but hands-on workflows that mirror the tasks faced by working analysts. You will write scripts, automate queries, extract intelligence from multiple sources, and produce reports that withstand professional scrutiny
